Canned food sterilization process 2017-08-30 00:38:53Canned fruit, in the end containing no preservatives - Add food food science food safety fruit canned, in the end containing no preservatives? This morning argued for a long time canned fruit, in the end containing no preservatives, the Internet said no, but in real life, we generally think there are, and that there is no iron, food additives added to the composition of what is the name, If not contain, how to prove it The The Up to the posture (do not take it for granted) 278705475 45 users 219 Under normal circumstances, the cans do not need to add preservatives, because the basic are sealed after sealing and then do sterilization, so after the completion of sterilization in a sealed state , The internal is sterile state. But as a result of small companies in the production of time to save the cost of sterilization to add some preservatives is not easy to say, the days of the manufacturer's imagination is infinite. The preservative used in the country is listed in GB 2760. Please refer to GB 2760-2014 National Standard for food safety food additive standards, as long as in accordance with the type of the standard and limited to add, are legitimate and can be considered safe. As for how to prove that no preservatives are really sad, all the types are checked again? Seems to be the behavior of burning it, and some other fruits may contain their own natural anti-corrosion ingredients, but also interfere with the test results, and seems to prove that they have no crime. BTW: say something extravagant, and now the media in order to find a gimmick, the additives demonized, the additive itself is no error, within the prescribed range without any security problems, and the food flavor, safety, preservation have played a great effect. For example, a bottle of drink, do you think is the risk of preservatives within the scope of compliance or the risk of microbial exposure? More brain remnants, to create the so-called \Say a few words, really like to eat canned fruit will not do their own words, just buy those regular manufacturers like the big. 2015-05-2954 User 6 Xie Lin invited to see before the problem is, just afternoon, nothing to answer this question. This thing is not to fight, no real right or wrong, some people are willing to say so, some people are willing to do so, some people are willing to sell so, some people are willing to buy so, some people are willing to eat ... ... can, but since the answer, first clear Point: why add preservatives; fruit cans are allowed to add; fruit canned is all fruit canned or a fruit canned; why do you want to prove this problem; food added the name of the preservative. Well, to answer, first of all, from the literally to understand the preservatives on the Well, the preservative is nothing more than the growth of food freshness and preservation time, it is clear and well understood, businesses add preservatives to increase shelf life by reducing Cost, which is also very consistent with the characteristics of businessmen Well, but this business is not good yet? On the black heart of it? Obviously not the case! The The Had to say that preservatives are a great invention in the human food industry, not only for businessmen, but also for all mankind, where there is no detail, single pull out can be said for several days, and as @ Claude Li In his answer, the use of additives as long as the use of a reasonable dose in the atmosphere are relatively safe (here also asked why I think you do not need to continue to read ~), but it is necessary to mention the The country's laws and regulations are different, although there are differences, but do not worry, there is no national legislation is to make their own nationals to eat and die, but also in the maximum edible amount will have a protective coefficient, after the end is the standard display Of the maximum available, China's protection coefficient is still relatively high, theoretically can be assured, but this does not affect the unscrupulous business to add chaos, so there are some such people know the misunderstanding \There are some degrees of possibility. To sum up: theoretically, canned fruit should be completely natural, it should not need any additives, and put a long time after and just picking is the same fresh. Of course, manufacturers are often not so good, they want to profit. Edit at 2015-05-3024 smallker more to see how much less to say. 2 first thank you @ Lin Jia's invitation.

Read the picture, we look at how GB2760-2014 Jun is the provisions of the. Propionic acid and its calcium and sodium salts can be used in the processing of canned cornflower, the maximum use of 50.0g / kg. Benzoic acid and its sodium salts and p-hydroxybenzoates and their sodium salts are prescribed and can not be used in jam cans. (Jam can also be considered in the canned fruit) sorbic acid and its potash can be used in jam. 1g / kg and then mentioned so much. Here's why the fruit cans are mostly preservatives. Because it is not needed. The role of preservatives is to prevent food spoilage, to extend the food storage period of the material. Canned fruit processing process involves sealing canned, that is, require 121 degrees Celsius, 15min sterilization operation, in this condition, the standard canned aseptic. That is, after loading canned, no bacteria. No bacteria, that even if the fruit canned in the environment (medium) nutrient content so rich, there is no way to reproduce. On the fruit will not cause the impact of flavor changes. (The words do other fruit canned after the flavor ...) so manufacturers do not need to add preservatives to prevent corruption. Having said that, food additives are the cornerstone of the development of modern food industry. We really do not need to talk about the kind of preservative ah like the tiger on the change. These are the ones that require the addition of the maximum added dose (regular manufacturer). Or that sentence, do not talk about the dose is rogue, as long as the manufacturers are in accordance with the provisions of the standard to add, then, consumer safety issues can be guaranteed. Pull away, hope that we can still correctly understand the food additives. Efforts to improve their level of posture is falling roar, we all need to learn one. 2015-05-292 Li Xiaoming 6002 food industry to eat a 1 first I want to tell you the production of fruit canned principle, you will know the answer after reading.

And vitamin C, is also a common food additives, but also the role of antioxidant. In summary, if in accordance with a more general definition, citric acid and Vc are considered a preservative. But in the inside to add the purpose of more can also be the taste of the debugging, not really for the anti-corrosion and deliberately added. In addition, add a preservative and do not be afraid.
