The Pap's milk was actually ignited, and it quickly opened up the market, but the arrival of some imported pasteurized milk was full of routines. There are irregular or misleading behaviors such as adding reconstituted milk and non-pasteurization, high temperature sterilization, pre-Pasteurization technology, and room temperature milk mixing into the freezer, which makes the Pap's milk market look like a mess. In the era when this routine was king, some so-called imported pasteurs from foreign countries also set a way for consumers. According to a survey conducted by the Beijing Business Daily, the shelf life of some imported pasteurized milk is twice that of the local pasteurized milk, and the product is not labeled with sterilization technology. Some products are labeled as “high temperature sterilization†but placed at low temperature. Shelves give consumers the illusion of low temperature pasteurized milk. The play of the normal temperature milk mixed into the freezer and the sterilized milk camouflage pure milk has been quietly staged. Not 100% pure milk Consumers buy fresh milk, and pasteurized milk is also considered the best interpretation of “fresh milk†due to its short storage time. However, the reporter's investigation found that the original imported milk on the supermarket shelves with a price tag of 20-30 yuan or even 60 yuan is not completely as fresh as consumers think. In a high-end supermarket in Beijing, the most concentrated imported milk comes from South Korea. Nanyang Ranch Milk, Yanshi Ranch Milk, and Jeju Lok Milk Milk are the most popular products sold by supermarket sales staff. However, the three milks have one thing in common, that is, the product types are all modulated milk. For example, in addition to raw milk, vitamin J is added to the ingredients of Korea's Yonsei milk, and another Nanyang milk is supplemented with calcium carbonate. However, industry experts pointed out that although the brewing milk sounds more "material" than pure milk, there are two points that consumers should be clear about: First, as long as the milk is not less than 80% of the milk content, The requirement for milk content is lower than that of pure milk; secondly, because of the addition of other nutrients, the nutritional content of each milk is more prominent in one item. For example, Korea Yonsei milk is added with vitamin D, and pure Compared with milk, the vitamin D content of 22% is more, and this content is outstanding, which means that this product is more suitable for people who need vitamin D, but on other ingredients such as protein, fat, carbohydrate, sodium and so on. It is not as good as ordinary pure milk produced in China. It is worth mentioning that this product does not have the same calcium nutrition as any other milk. Previously, the inspection data released by the Ministry of Agriculture's Milk and Dairy Products Quality Supervision, Inspection and Testing Center showed that the thermal damage of imported milk was 15.8% higher than that of domestic milk; the pasteurized milk was mostly pseudo-Pap milk, and the detection of 4 products had 2 products. Unqualified, there is added reconstituted milk and non-pasteurized. Extended shelf life The so-called pasteurized milk refers to the milk treated by pasteurization. The sterilization temperature is low, the storage condition is refrigeration, and the shelf life is short. It is the three characteristics of pasteurized milk. Since not all products are labeled with sterilization technology, consumers usually The length of the shelf life is used to distinguish which one is pasteurized milk. For example, taking the local market in Beijing as an example, the shelf life of ternary organic fresh milk is 7 days, and the product is clearly marked with storage conditions of 2-6 degrees Celsius; the shelf life of another organic sweet milk is also 7 days. The storage method is Refrigerate at 2-6 degrees Celsius. Both products are also labeled as pasteurized milk. However, unlike the two local pasteurized milks, imported pasteurized milk from abroad is more relaxed in shelf life. For example, the shelf life of South Korea's Jeju Lohas milk is 15 days, the shelf life of Korea's Nanyang Ranch milk and Korea's Yonsei milk are also 15 days. In addition, the storage conditions of Nanyang Ranch are 0-10 degrees Celsius. Dairy expert Song Liang told the Beijing Business Daily that a few companies will use membrane filtration technology to filter out spores, somatic cells, reduce the number of bacteria, and then cooperate with new packaging, which may extend the shelf life to 20 days. However, some companies may have used the UP technology of Super Pap. “UP refers to instant sterilization at ultra-high temperature above 130 degrees Celsius, and then rapid cooling, the shelf life can be 20-30 days, but the result of this technology is high temperature sterilization, sterilization with pasteurized milk 72-75 degrees Celsius It is a completely different process, and the active nutrients in the product are also different. Therefore, it can only be called pseudo-Paste." Song Liang said. Some business people also revealed that in addition to this technology, there is another kind of pre-Pasteurization technology, which is two pasteurization. This kind of technology can also extend the shelf life of milk, but after repeated sterilization, it is likely to damage. Some trace elements that are sensitive to heat are somewhat different from what people often call low temperature pasteurization. Normal temperature milk mixed into the freezer It is worth mentioning that some of the imported milk products are marked with “pasteurized milkâ€. For example, a2 milk from Australia has been used for sterilization technology. Domestic pasteurized milk is also clearly marked with technical means, but the above Three milk from South Korea did not make any explanation on the bottle. “So, consumers can only judge from low temperature storage that this may be pasteurized milk, but it is not known whether low temperature pasteurization technology is used.†Some dairy companies say. Even more milk has been marked "high temperature sterilization" in the bottle body, but it is still placed in the low temperature area, and marked "2-6 degrees Celsius refrigeration". The above-mentioned dairy enterprises further said, "This is a misleading behavior. If it is high temperature sterilization, it can be stored directly at room temperature. It is not necessary to appear in the low temperature zone. This is just to make consumers mistakenly think that it is cold storage. Milk is not." Song Liang previously pointed out that although foreign companies and agents arrange the pasteurized milk market, pasteurized milk is low-temperature sterilization, which has strict requirements for transportation and storage. If the control is not strict, the quality of the pasteurized milk will be severe. problem. Previously, low-temperature pasteurized milk from Australia detected pathogens many times, so the National Certification and Accreditation Administration suspended the registration of problem companies in China, and comprehensively strengthened supervision of all Australian low-temperature milk companies. The problem comes from the discovery of unqualified products in Australia's multi-batch imported pasteurized milk products. One of the Australian companies' products have repeatedly detected the pathogens such as Staphylococcus aureus and Escherichia coli. The quality control of pasteurized milk is the most difficult to carry out, which also makes many true pasteurized milk discouraged, but it provides a space for the pseudo-buses to survive. Of course, this is also very necessary for the education of consumers. Through the spread of knowledge of pasteurized milk, consumers can recognize the truth and falsehood. Imported Pseudo-Pap milk has been widely used in the Chinese market. A few days ago, the inspection data of the Ministry of Agriculture's Milk and Dairy Products Quality Supervision, Inspection and Testing Center for seven years showed that the thermal damage of imported milk was 15.8% higher than that of domestic milk; the pasteurized milk was mostly pseudo-Pap milk, and 4 products were tested. 2 unqualified, there is added reconstituted milk and non-pasteurization. If you want to break the routine of Pap's milk, you need to see the tricks, recognize the labels, and let the pseudo-Paste milk be invisible. Pasteurized milk shelf life 7 days The Ministry of Agriculture's Milk and Dairy Products Quality Supervision, Inspection and Testing Center tested four imported pasteurized milk: two sampling locations in Guangzhou and two from the Internet e-commerce platform. The result of the test was that two imported pasteurized milk sold in Guangzhou were unqualified: one containing reconstituted milk and one non-pasteurized (sterilization temperature far exceeding 80 degrees Celsius), and two pasteurized milks sold from the Internet were qualified. It is understood that the domestic ultra-high temperature instantaneous sterilization (UHT) milk shelf life is 151 days on average, and imported milk is 310 days. UHT milk shelf life: domestic vs import, 53 days vs 180 days; pasteurization shelf life: domestic vs import, 2 days vs 9 days. It is understood that the main mode of transportation of imported liquid milk is sea transportation. The shipping time from Europe to China is about 6 weeks. During the period, there are import inspection procedures, and the sales time in the market is mostly more than 2 months. This will undoubtedly lead to a longer shelf life of imported liquid milk, which is why the shelf life of imported liquid milk is very long. Imported liquid milk is transported over long distances and long-distance long-distance sea transportation. The general transportation period is 2 months, and it is exposed to the equatorial area for a long time. The quality of milk is greatly affected. The shelf life of imported pasteurized milk sold in supermarkets is about 20 days, and some can even reach 40 days, while the shelf life of domestic pasteurized milk is generally 2-7 days. In this regard, industry insiders analyzed that the shelf life of good pasteurized milk is only two or three days, and the shelf life of pasteurized milk which is slightly worse is about 7 days. The shelf life of imported pasteurized milk can reach 15-30 days, which shows that it is Pseudo-Pap's milk treated with high temperature and high pressure. Therefore, when purchasing imported pasteurized milk, you can carefully read the shelf life on the label and try to choose pasteurized milk with a shelf life of 2-7 days. Modulated milk is not pure milk In general, the price of imported pasteurized milk is relatively high, but whether it is genuine or not is questionable. There are fewer brands of imported pasteurized milk, but problems have been found in the four products of the imported pasteurized milk. The investigation found that imported pasteurized milk was found to contain added reconstituted milk. Although imported milk powder is now imported into China in large quantities, resulting in the fact that domestic products now have reconstituted milk, it is now found that imported milk also contains reconstituted milk. According to industry insiders, neighboring countries such as Japan and South Korea added more reconstituted milk to Pakistani milk imported from China. Some pasteurized milk with milk is also understood as reconstituted milk. For example, a Korean imported milk called “Nanyang Ranch Milk†was placed in a freezer. The ingredients were Korean origin milk and calcium carbonate. The type of product is milk. The ternary organic fresh milk ingredients which are compared with the same freezer are organic raw milk and full fat pasteurized milk. In addition, the formula of some imported pasteurized milk is also marked with ingredients, that is to say, these imported pasteurized milk is not fresh milk. It can be seen that the imported pasteurized milk is mostly pseudo-Pasteurized milk. According to national food safety standards, brewed milk is different from pure milk that consumers usually know. Both are based on raw milk, but different production processes are used, and the milk content is also different. Pure milk is a liquid product made from raw milk and using appropriate sterilization or sterilization processes. The nutrient content is mainly nutrients contained in natural milk, and the milk content is 100%; the milk is prepared in raw milk. On the basis of adding other raw materials or nutrient-enhancing substances, liquid products made by a process such as sterilization or sterilization, the milk content is not less than 80%. Modulated milk strengthens some nutrients, such as calcium and other trace elements, making it higher than ordinary pure milk products. Therefore, when purchasing Papillon milk, the ingredients in the formula need to be carefully watched. High temperature sterilization non-Pasteurization process The high temperature and high pressure treatment caused the thermal damage of imported milk to be 15.8% higher than that of domestic milk. According to analysts, imported milk has to be treated with high temperature and high pressure in order to extend the shelf life, including three processes, namely ESL process, high-pressure instant sterilization process and high-temperature instant sterilization process. These processes make the thermal damage of imported milk higher than domestic milk. For pasteurized milk, the high temperature treatment of imported pasteurized milk is also much higher than that of domestic pasteurized milk, resulting in higher thermal damage. Milk treated by pasteurization at low temperature has a short shelf life, requires refrigeration, and does not require the addition of preservatives. It is truly fresh and safe, and “normal temperature milk†is high temperature sterilization. It does not need to be refrigerated and can be stored at room temperature, but because At high temperatures, some of the heat-labile nutrients in the milk are destroyed. Domestic milk heat damage is low, and the proline content is less than 15.8%. Proline is an indicator of heat damage. The higher the value, the higher the degree of milk heat damage. The average value of domestic milk glycine is 196, and that of imported milk is 227. Because the imported liquid milk is very hot in the container, if it is subjected to a long transportation process, its value can easily reach a higher level. When consumers buy Papillon milk, they can distinguish it by observing the label on the bottle. Ordinary domestic pasteurized milk is usually marked with "low temperature sterilization" or "Pasteurized low-milk milk" on the bottle, and the milk marked with "high temperature sterilization" can be concluded that this is not pasteurized milk. It should be noted that not only the pasteurized milk will be displayed in the freezer, but some merchants will mix the normal temperature milk into the freezer and pretend to be the pasteurized milk through the high price. The consumer needs to see the label when purchasing. So as not to be deceived. Experts said that if consumers need to buy pasteurized milk, it is recommended to buy domestic pasteurized milk as much as possible. In terms of quality, domestic milk is not worse than imported products, and the production is near, and food safety can be guaranteed. When more routines are revealed, when some false features are uncovered, what are the benefits for merchants and manufacturers? Lost word of mouth and the trust of consumers, there are many routines, and it is inevitable that they will go downhill or even close down.
