Various preservatives are added to food to prevent spoilage caused by bacteria, molds, fungi and yeast. Preservatives extend the freshness and shelf life of food. Food preservatives are also used to slow or prevent changes in color, taste or texture and to delay food spoilage.

Edible gelatin and industrial gelatin are gelatin, basically no difference in appearance, the average consumer can not identify, and the difference lies in the raw materials and different uses. The reason why there will be gelatin in yogurt, jelly and other foods is because gelatin has the physical and chemical properties of strong water absorption and high viscosity, coupled with a fat-free, high protein, cholesterol-free, so gelatin becomes a natural nutritious food thickening agent for yogurt, jelly, Xiao Long Bao and other foods to add a certain texture to be used, but also has a certain role in preserving freshness.
To add gelatin to food is known as food gelatin, food gelatin is the use of fresh animal skin by strict safety production control boiling extracted collagen protein, non-toxic and harmless, as long as the requirements of the country in accordance with the packaging labeling, it is not illegal, the public do not need to worry about safety issues, from a nutritional point of view, the addition of food gelatin will not affect the original nutritional value of food.
The main character of the recent public unpleasantness is another use of gelatin - industrial gelatin. Industrial gelatine is widely used in a variety of products in the sheet metal, furniture, matches, packaging, paper and other industries, and in which it mainly plays a role in thickening, stabilizing, cohesion and so on. Because it is not used for food, the boiling process is relatively simple, in which preservatives are also added, and its use for food is strictly prohibited.
Now the common practice is to collect leather trimmings, through a series of processes, from the leather will be hydrolyzed proteins out, made of gelatin, so can effectively use the waste leather, reduce costs. But the problem is that the waste leather contains a lot of metal chromium, and in the process of dehydrolyzed proteins chromium can not come off clean, so the industrial gelatin with toxicity, if only used for industrial production, will not cause damage to human health.
Foods with gelatin are not vegan
Gelatin as a food thickener, used in meat jelly, canned food, candy, sausage, fans, instant noodles, ice cream and other food industries, and food to add a thickener in one of the purposes is to increase the strong taste, such as vermicelli, instant noodles, etc.; Secondly, in order to prevent impact in the process of transportation leads to the collapse of the product shape, such as yogurt. There are many netizens mistakenly believe that fans, vermicelli, yogurt, etc. belong to the vegetarian diet, which is a kind of misinterpretation.
This is a misinterpretation because gelatin is added during the production of vermicelli, and gelatin is a product boiled from the skin, bones, tendons and other parts of the animal, so if there is a product that contains gelatin, it can't possibly be vegan, and therefore some vegans shouldn't choose to add gelatin to their products.
Nowadays there are some all-vegan gelatin substitutes such as guar gum, carrageenan, etc. There are also many vegan substances that have the same ingredients as gelatin, such as cellulose, agar, guar gum, xanthan gum, carob fruit, fruit jelly, etc., so if you read the ingredients list and see that there is gelatin, then you can know that it's not vegan, but if there are any of the vegan substances mentioned above in the ingredients list, even if you're a vegan, you can eat it now.
