Gelatin is actually a common item in daily life, and food with gelatin is not vegetarian, we should look at it correctly and should not choke on it.　　What is gelatin? Conceptually, gelatin is a peptide molecule made from boiled animal bones, skin and tendons, is a collagen protein hydrolysis product, contains a large number of amino acids, has a high nutritional value. This thing is actually not far from life can not be common, the people at home boiled big bone soup condensation, the surface of the soup will appear a layer of clear and transparent slightly amber-colored jelly-like objects; there are some areas will be consumed a "jelly", made of long strips, the texture if the jelly, but contained in the mouth in the event of heat will be melted, is quite a lot of old people like the cold dishes! ...... These things are actually gelatin, therefore, gelatin is not far from our lives, and is not something terrible, we do not need to gelatin word too much panic.　　　　In fact, edible gelatin and industrial gelatin are gelatin, from the appearance of the basic no difference, the average consumer can not identify, and the difference lies in the raw materials and different uses. The reason why yogurt, jelly and other foods will have gelatin, because gelatin has a strong water absorption, high viscosity physicochemical properties, coupled with a fat-free high protein, does not contain cholesterol, so gelatin becomes a natural nutritional food thickening agent for yogurt, jelly, steamed dumplings and other foods to increase a certain degree of texture and the use of the same time, but also has a certain degree of preservation of the role of 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 the role of thickening, stabilization, 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 protein chromium can not be removed cleanly, so the industrial gelatin with toxicity, if only used for industrial production, will not cause damage to human health.　　Add gelatin food non-vegetarian 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.; the second is to prevent the impact in the process of transportation leads to the collapse of the product shape, such as yogurt. Many netizens mistakenly believe that vermicelli, vermicelli, yogurt, etc. are vegetarian, which is a misinterpretation. Because fans and so on in the production process added gelatin, and gelatin is from the animal skin, bones, tendons and other parts of the boiled product, so if there is a product containing gelatin, it can not be vegan, so some vegetarians should not choose to join the gelatin products.
