China Packaging Network News] Remember not to buy food from unknown sources. Food packaging labels on the label is unknown, or is completely foreign language logo, or not on the sale of food in a fixed place should be careful, this kind of food may be relatively cheap, but it is not guaranteed, can people feel at ease to eat it? Do not think that frozen foods can be stored for long periods of time without fear, and its shelf life is actually only one or two months. It is not easy to judge how long it takes to store and store frozen foods in supermarket freezers. Therefore, don't let frozen dumplings, frozen meats, etc. fill the refrigerator freezer when you're working again. Frozen foods are best bought now. Pay attention to the preservation temperature of frozen foods. When buying frozen foods, it should be chilled and stored below -18°C, and it is hard when it is picked up, not wet and soft. The food that has been a bit thawed may have already begun to decline in quality. Buy canned food and note good canning. When choosing canned foods, you must choose a good and complete can body, no unevenness and rust; in addition, special attention must be paid to the can body QS production license signs and numbers in order to feel comfortable buying. The food logo must be complete. For fresh packaged foods purchased in supermarkets, in addition to price, we must also carefully look at whether the information on the packaging is complete and detailed, such as: net food content, name, food additives, name of the manufacturer, address, contact information, shelf life, and origin And production date.

Journal of China Science and Technology Journalist Zhao Guangli Foods, beverages, cosmetics... Are these products thrown or used in the last few days of shelf life? This is a problem. Some nutritionists point out that the definition of shelf life is [the quality guarantee period of products under normal conditions", which means that during the warranty period, the merchants are responsible for the quality of the products, but the shelf life does not equal to the last available time. For example, rice, coffee and other foods are still edible after the expiration date. Yan Chunhua, an academician of the Chinese Academy of Sciences and a professor of the School of Chemistry and Molecular Engineering of Peking University, did not think so: [In most cases, the shelf life of the product packaging is stated in the following: 'This product is always under proper conditions during transportation, storage and sales ( If the temperature and humidity are appropriate, the package is not damaged, the product is not contaminated, etc.) Presumed under the premise of preservation, since the product inevitably undergoes changes in temperature during these processes, especially for medical supplies such as vaccines. The shelf life indicated on the product packaging does not have sufficient credibility, which may pose a threat to public health." The two points of view are diametrically opposed, but there is one point where the two sides reached a consensus: The shelf life is not the only criterion for determining whether food is deteriorating. This in turn makes friends who are entangled in [throw or use" even more confused: how do we judge whether it is deteriorating? The research on "color-changing smart labels" led by Yan Chunhua et al. proposes a solution. This is a [color-changing smart label" that purportedly [indicates the real-time quality of perishable packaging products." Researchers cleverly use the common color-changing reactions in chemistry to indicate the quality of packaged products in real time. What did the researchers do about the label? Yan Chunhua took E. coli in milk as an example. According to a reporter from the China Science Journal, in the normal temperature range (0°C to 35°C), the reproduction rate of E. coli accelerated with increasing temperature; similarly, large The rate of most chemical reactions also increases with temperature. If a specific chemical reaction can be found and its reaction rate at each temperature is consistent with the propagation rate of E. coli, the two are mathematically equivalent. "Thus, if a smart label is prepared with this chemical reaction, the label is placed on the packaging box when the perishable product such as milk is shipped - this guarantees that the two will experience the same temperature history and can use the chemical reaction in the label. Tracking, simulating and instructing the quality change process of the product," said Yan Chunhua, adding that in order to facilitate the reading of relevant information, chemical reactions that change color over time should be used. In other words, the design of the smart tag is based on the fact that the process of degrading the milk and the process of changing the color of the label are synchronized at any temperature. In search of label materials, the researchers selected the "Gold Nanorods Epitaxial Silver Shell Growth" chemical reaction. According to reports, the gold nanorod aqueous solution is red, and after the silver source (silver nitrate) and the reducing agent (vitamin c) are introduced into it, the resulting elemental silver is deposited on the surface of the gold nanorods to form a "core-shell structure" ( Nano-materials - such as silver particles, nano-scale ordered assembly structures formed by chemical bonds or other forces that coat another nano-material. As the "silver shell" thickness increases, the solution changes from red to orange, yellow, green, and even blue and purple. Yan Chunhua told reporters that at room temperature, the time required for this chemical reaction process can be adjusted within minutes to months (or even longer). In addition, the researchers also found a simple and easy way to adjust the sensitivity of the reaction to temperature changes (ie, the apparent activation energy, the apparent activation energy can be adjusted in the range of 50 ~ 190kj/mol or even wider) . [The range of these parameters covers the metamorphic kinetic parameters of the vast majority of perishable products, and thus can track, simulate and indicate the real-time quality of the vast majority of perishable products." Yan Chunhua said that researchers have used E. coli as an example. Synchronization of food spoilage and label discoloration has been achieved at multiple temperatures. "This is expected to be achieved at any time by the color of the label, which can be used to reverse product quality without even having to open the product package." Yan Chunhua and associate professor Sun Jingdong's research group completed the study in collaboration with the research group of the Faculty Fellow Chen Xing of the Faculty and Wang Jianfang's team of the Physics Department of the Chinese University of Hong Kong. Once this study was reported at the 247th American Chemical Society Spring Conference and Expo 2014, it received extensive attention from academia, industry, the media, and the public. According to reports, although the follow-up work of the research is still in progress so far, there have been a number of well-known foreign companies that have sent in letters to consult relevant results and discuss industrial cooperation. The reporter learned that there have been some technologies that have been dedicated to solving the problem of monitoring the quality of perishable foods, such as using a data logger to track and record the temperature changes experienced by the product. These technologies are often costly, and it is difficult to completely cover the entire process of the product from the manufacturer to the consumer, and it is difficult for consumers to read the information recorded therein intuitively. In comparison, the "color-changing smart label" is more reliable and safer, and its raw materials have no toxic or side effects. Yan Chunhua is full of hope for its productization: [This label is expected to expand the current product quality monitoring range from 'manufacturer to consumer', and advance monitoring accuracy to a single package level with high potential. Value."

Beijing, May 11th, 2015: The report on genetically modified foods sold by supermarkets of the North Greenfield Plaza, released by the International Environmental Protection Organization Greenpeace today, shows that over 30% of the sample samples tested contained genetically modified components, including Pleasant potato chips, Vivivita-type soy milk, and Nestle's egg milk stars, etc. However, none of these products have any genetically modified signs on their packaging. Greenpeace called on the Ministry of Agriculture to improve GM labeling regulations and regulations, strengthen supervision, give the public full rights to know about GM issues, and ensure that consumers` legal rights in food choices are protected. "Without the logo, there is no possibility of choice," said Wang Wei, director of the Greenpeace Food and Agriculture Project. "People are consuming genetically modified food without knowing it." Greenpeace conducted random sampling of foods containing rice, soy, and corn components in major supermarkets in Beijing, Shanghai, and Shanghai from January to March 2015, including domestic and imported foods. There are many domestic and foreign brands, such as PINK, Nestle, and Vivi were sent to independent third-party laboratories for testing of genetically modified components. Among the 43 foods spotted and tested, 14 samples were found to contain genetically modified components, accounting for more than 30% (33%) of the samples. In particular, 2 of the 9 Nestlé-branded foods sampled contain genetically modified ingredients. In addition, nearly 40% (36%) of imported foods that are generally considered [high-end and safe" by consumers have been detected containing genetically modified ingredients, such as Pringles chips. All of the above-mentioned foods containing the genetically modified components were not clearly identified. [At present, the proliferation of foods containing GM ingredients but not indicated in the market indicates the dereliction of duty by the Ministry of Agriculture. At the same time, the opaqueness of the Ministry of Agriculture in the disclosure of genetically modified information has led some consumers to launch actions to defend the right to know and choose." Wang Say it. Earlier this year, following the case of Huang Leping`s lawyer and citizen Yang Xiaolu`s filing of an administrative litigation against the [Ministry of Agriculture" on [opening of genetically modified information", on February 10th, Beijing Yipai Law Firm filed an [Application for GM Crops Research Status quo to the Ministry of Agriculture. Administrative lawsuits involving violations of penalties are formally filed in the court. Less than six months later, the Ministry of Agriculture became the defendant for the third time, and the reasons for the case involved all involved the disclosure of genetically modified information. Greenpeace appealed to the Ministry of Agriculture and related departments to speed up the renewal and improvement of genetically modified signs and regulations, remove the illegally-tested genetically modified foods and thoroughly investigate the sources, and effectively protect the legitimate rights and interests of consumers. Greenpeace also hopes that the Ministry of Agriculture and local agricultural administrative departments can openly disclose genetically modified information, give consumers full rights to know about genetically modified issues, and use public opinions as an important basis for formulating laws and regulations.

What is the difference between RF technology and bar code? Conceptually speaking, the two are very similar. The purpose is to quickly and accurately identify the target object. The main differences are as follows: Is there any ability to write information or update memory. The memory of the barcode cannot be changed. RF tags are unlike bar codes, and their unique identifiers cannot be copied. The role of the tag is not limited to the field of view, because information is transmitted by radio waves, and the bar code must be within sight. Due to the low cost of barcodes and the existence of a well-developed standards system that has spread around the world, it has been generally accepted. On the whole, radio frequency technology is limited to a limited market share. At present, a variety of bar code control templates are already in use. In terms of access to information channels, radio frequency has different standards. Radio frequency technology and bar code are two different technologies, have different scopes of application, and sometimes overlap. The biggest difference between the two is that the bar code is "visual technology". The scanner works under the guidance of a person and can only receive bar codes within its field of view. In contrast, radio frequency identification does not require seeing the target. The RF tag can be read as long as it is within the scope of the receiver. The bar code itself also has other drawbacks. If the tag is scratched, contaminated or falls off, the scanner cannot identify the target. Bar codes can only identify producers and products, and cannot identify specific products. Bar codes attached to all packages of the same product are the same and it is impossible to identify which products have expired first. At present, in terms of cost, smart labels are much more expensive than barcodes because of different components. The cost of barcodes is the cost of barcode paper and ink, while the price of active RFID tags with memory chips is more than US$2, and the cost of passive RFID tags is also Above 1 USD. However, the price of a tag without a built-in chip is only a few cents. It can be used for situations where the data information is not so demanding, and it also has anti-counterfeiting features of anti-counterfeiting technology products that do not have bar codes. in conclusion RFID technology is at an early stage in China, but its development potential is huge and its prospects are very attractive. In the information society, the requirements for the acquisition and processing of various kinds of information are fast and accurate. In the near future, RFID technology will penetrate into our lives and improve our lives as much as other identification technologies. For such a new technology, we should strengthen our propaganda. We hope to popularize it as soon as possible and use it to improve our work efficiency and economic efficiency. In contrast. I still think that the management and standardization of RFID applications need to catch up. Otherwise, many manufacturers will behave in different ways, causing fait accompli, and it will be difficult to unify management. Now that the international standards for RFID have not yet been completed, there are only a few industry standards, which brings certain difficulties to the standardization work. But from a strategic point of view. This issue is becoming increasingly urgent.

1. Development background Based on the manual management of conference rooms by many large and medium-sized enterprises, the conference rooms on each floor are free-the reservation status cannot be known in time. In order to further standardize the use / reservation management of conference rooms and avoid resource conflicts. The ENC-MEETING conference room management system based on the B / S structure independently developed by our company, users only need to know the current status and reservation status of each conference room at any time through the Internet, which improves the utilization rate of the conference room and saves meetings Organizer's time. 2.

Roles correspond to permissions, users correspond to user groups, and user groups correspond to roles. No matter how users change, they will not cause confusion in permission control, making user rights management safe and secure. 3.3 Support SMS and email notification The ENC-MEETING conference management system and mobile technology are fully integrated, and once the conference is confirmed, SMS and email notifications will be sent to the participants in advance to avoid absences and lateness, which can effectively improve the efficiency of conference execution. 3.4 Overall allocation of conference resources In the actual operation of the enterprise, sometimes there is a phenomenon of conflicting conference resources. In the past, once different conference groups used the same conference resources at the same time, such as holding meetings in the same conference room at the same time, the result caused unnecessary Embarrassment. The ENC-MEETING conference management system fully takes this into consideration. When applying for conference resources, it judges the usage time of the conference room. If there is a situation of using the conference room at the same time, the applicant will be reminded to perform relevant processing. 3.5 System Security Security is a very important part of the information system of enterprises and institutions, especially important meetings. Once the content of the meeting is leaked, it will have a very serious impact on enterprises and institutions.

IHI Marine United (IHIMU), a Japanese shipbuilding subsidiary of IHI, signed a technical cooperation agreement with the EAS shipyard (Estaleiro Atlantico Sul), the largest shipyard in Brazil, on the 27th. The EAS shipyard delivered a Suez-type tanker in May this year. The plant is still holding 21 Suez-type tankers, Aframax tankers and 7 drilling platform ships. As the only shipyard in Brazil to build large-scale ships and offshore projects, EAS Shipyards is working with IHIMU to increase productivity, deliver on time, improve plant operations, and seek technical support partners. In July, IHIMU will dispatch a technical support team to the shipyard as a technical support.

EAS system security is a new technology for customer surveillance anti-theft With the development of science and technology and the quest for efficiency, today's traditional theft prevention methods for retail stores using human power to monitor shopping malls are no longer appropriate. Instead, high-tech electronic goods theft protection systems will be used instead. The theft of retail merchandise is a worldwide problem. According to statistics from abroad, the loss of a US$9.34 worth of goods requires US$849 in turnover to recover losses. The loss of commodities undoubtedly aggravated the burden on the company. For this reason, loss prevention has gradually become the focus of domestic business leaders. As early as the late 1960s, the United States had the first electronic article surveillance (EAS) electronic article surveillance (Electronic Article Surveillance). Fundamentally changed all previous anti-theft measures aimed at customer monitoring. The implementation of anti-theft surveillance on commodities prevents consumer resistance and this anti-theft deterrence has been agreed by many retailers. At present, most large-scale retail companies in the world use electronic anti-theft devices. The installation rate of EAS systems that entered the Asian countries 10 years ago, Japan, Singapore, South Korea, and Hong Kong and Taiwan has been increasing year by year. After Chinese enterprises accepted electronic anti-theft systems in the 1990s, they began to install EAS systems in shopping malls in Beijing, Shanghai, Guangzhou, and Shenzhen. After 40 years of development, the electronic anti-theft system has evolved from a single single-principle single product to a wide variety of different principles and adapts to the needs of different types of stores such as department stores, supermarkets, specialty stores, and libraries. 1. Subdividing from the form of protection can be divided into vertical system, concealed system and channel system. The detection system of the vertical system stands proudly at the entrance and exit of the shopping mall and has a clear deterrent effect in addition to the detection function. The concealed system conceals the system under the carpet under the exit or at the ceiling. It does not affect the overall environment of the store and can also function as a theft protection to meet the needs of the owner who is both beautiful and anti-theft. The channel system integrates the EAS system with the cash register at the exit of the supermarket to form a channel-type protection, which is an effective method to achieve theft prevention in the supermarket. 2. It can be divided into radio system, electromagnetic wave system, microwave system, frequency division system, intelligent system and acousto-magnetic system. (1) Acoustic-magnetic system The tuning fork only causes resonance if the oscillation frequency is the same. Acusto Magnetic (Acusto Magnetic) is the application of this physical principle to achieve almost zero false alarm operation. When a sound-magnetic system tag fixed on a commodity enters the detection area of the system, it will generate resonance but it will only be received by the receiver. The alarm is issued only after four consecutive resonance signals (once every 1/50th of a second). The characteristics of the acousto-magnetic system are high anti-theft detection rate, almost zero false alarms, good anti-interference, and the protection of the export width of up to 3.5 meters, there are two anti-theft labels soft and hard, for most types of shopping malls can be protected, and Demagnetization can be repeated, even if the system is still working at the POS cash register. The acousto-magnetic system includes vertical system, channel system and concealed system different types. There are more than 10 models to choose from, which can be widely used in department stores, supermarkets, specialty stores, audio-visual shops, grocery stores, pharmacies, etc. Office buildings and other environments. (2) Radio System (Radio Frequency, RF) uses radio waves as signals for transmission and reception, detects electromagnetic waves in the frequency range of 7.4-8.8 MHz, and has a center frequency of 8.2 MHz. Call the police. The biggest advantage of the radio system is the very low system cost and easy installation. However, since its anti-theft tag is a toroidal coil type, the system is susceptible to interference from some items, such as electronic products such as cash registers and metal objects, which cause false alarms or non-reports of the system. The radio system has two labels, soft and hard, that can protect most items in the mall. The distance between two bearings can not be more than 0.9 meters, usually used in a shopping mall with only one import and export. The radio system has two types, vertical and channel, for the protection of department stores, clothing stores, and supermarkets. (3) Electromagnetic wave system Electromagnetic wave system (Electromagnetic System) uses electromagnetic waves as detection signals. The electromagnetic wave system has the smallest label, the label price is also low, and the demagnetization can be repeated, but it is susceptible to the occurrence of false positives due to the influence of magnetic or metallic substances. The protected exit width is generally about 0.9 meters. The system will not affect magnetic objects (such as audio tapes, video tapes, magnetic cards). The new generation of channel-type electromagnetic wave system is a software-controlled electronic anti-theft system, using digital processing technology and degaussing system, cashier monitoring, closed-circuit television monitoring system. The use of fast degaussing plates enables repeated demagnetization and high system costs. There are two types of electromagnetic wave systems: vertical and channel. The application environment is mostly in libraries, bookstores, sound shops, hotels, supermarkets, etc. (4) Microwave System The Microwave System uses microwave as a detection signal and is not easily disturbed by the surrounding environment. It can be installed in a flexible and concealed manner (such as hidden under a carpet or suspended from a ceiling), and is suitable for interior decoration and aesthetics. The advantages. However, due to the large scale of Shengying, it is impossible to arrange products in a certain area. This would limit the use of space for merchants with a high price of land. Therefore, it is suitable for use in large department stores and large music stores and fashion stores. (5) Frequency division system Frequency division system (SplitFrequency) is a high-tech frequency division technology and ultra-low frequency radio wave signal anti-theft system. When a security tag enters the detection area, the tag receives the signal transmitted by the transmitting device, divides it into half, and then transmits the divided information to the receiver. Only when the receiver receives half the signal Sending an alarm can effectively avoid interference from other radio waves. The system is light in label, small in size, cheap in price, stable in performance, high in detection rate, good in anti-interference, and less likely to cause false alarms. There are two kinds of vertical and concealed products, which is an ideal anti-theft system for clothing and apparel. (6) Wisdom system The unique technology of the smart system application is an internal integrated circuit control, battery drive, hard tag and alarm group. When the tag is picked up or taken out of the store along with the product, the system automatically sends an alarm. The system enables the entire store to be protected, with no errors, and the labels can be reused without damaging the merchandise. It is used to protect valuables, such as fashion, leather, and clothing. (7) Destruction principle The anti-theft system of the system destruction principle is a hard tag or magnetic lock. The ink is contained in a hard tag. When the thief attempts to remove the hard tag, the hard tag will eject ink, contaminating the body of the goods and the burglar. Magnetic lock is very difficult to dismantle, forcibly remove it will destroy the goods, it is easy to use, has a good deterrent effect, and the cost is very low, applied to clothing, glasses, jewelry, ties, silk and other goods, the label can be reused. In addition to electronic article surveillance systems, closed-circuit television monitoring systems (Closed-Circuir Television, CCTV) are closely related to theft prevention in shopping malls. Closed-circuit television monitoring systems can monitor what is happening in shopping malls and discover suspicious events and act as deterrents to deter use. Compared with the electronic anti-theft system, the advantage is that it can not only effectively monitor the situation in the mall, and can use the video tape to record the incident or theft process, as the basis for the follow-up investigation and evidence collection. Conditional shopping malls can combine electronic anti-theft systems with CCTV. This can effectively prevent internal and external thief crimes, increase theft prevention effect, and reduce the loss of retail goods.
