Industrial, medical gelatin, what is industrial grade gelatin What is the role of gelatin?

Medical gelatin: the appearance is light yellow or yellow particles, dry, clean, uniform, no inclusions, and its solution has no uncomfortable odor. The products are mainly used as raw materials for soft and hard capsules, hemostatic sponges, and tablet icing.

Use. Gelatin's gelatin, water fixability, adhesion and solubility, as well as its chemical purity, make gelatin have a wide range of uses in the pharmaceutical industry, the most important of which are hard capsules, soft capsules, plasma substitutes and coatings.

Quality standards for medicinal gelatin.

Industrial gelatin: Industrial gelatin is a protein that is hydrolyzed from collagen moieties in the connective or epidermal tissues of animals. It has many excellent physical and chemical properties, such as the formation of reversible gels, cohesiveness, surface activity, etc., and is widely used as jelly, emulsifier, stabilizer, binder and clarifying agent in the food industry.

Identification of gelatin. There are three ways to make an initial identification.

1. Industrial gelatin products are generally of poor quality, more impurities, less viscosity and toughness, so they are particularly fragile, if these are found in the purchased products, it can basically be judged that industrial gelatin is added.

2. Industrial gelatin products generally have bright colors. Because edible gelatin is transparent, white, and clean, while industrial gelatin has many impurities. If industrial gelatin is used, the manufacturer will add more flavors, dyes, and colorants to cover up impurities, so the brighter the color, the more likely it is to be made of industrial gelatin.

3. The things made of industrial gelatin, because it is to reduce costs, are often poor in quality, materials, technology, and environment, so the products made are not exquisite.

Technical standards for industrial gelatin.

First, it is used in the match manufacturing industry, mainly using the foaming property of the colloid to form pores, combining oxidants, agents and fillers to make them ignite instantly. Second, as a binder, using its high strength, elasticity and toughness, it is used to produce abrasive cloth, sandpaper, bonded wood, bound books and used in gift box assembly lines, high-end musical instruments, and furniture industries.

The third is electrolysis, which is added to the electrolyte to help generate a smooth, dense anode precipitation and eliminate production losses. Fourth, it is used for textiles, which can form a film on the yarn bundle, so as to increase the toughness, strength, smoothness and elasticity of the fiber, and prevent breakage. Fifth, it is combined with dichromate to manufacture negative photosensitive corrosion-resistant film.

Sixth, hydrolyzed protein is extracted and used in additives.

In short, industrial gelatin is widely used in various products in plates, furniture, matches, feed, packaging, papermaking, textiles, silk, printing and dyeing, printing, ceramics, petroleum, daily chemicals, coatings, metallurgy and other industries, and mainly plays the role of thickening, stabilizing, coagulation, blending, glazing, sizing, bonding, water fixing and so on.

Industrial gelatin and edible gelatin, industrial gelatin is used to make film, film, etc., there is no restriction on heavy metal notices, edible gelatin is used in the production of food, belongs to food additives, can be edible.

The main differences between the two are: different raw material standards and different production environments.

Edible gelatin production enterprises shall obtain a food production license.

According to Article 22 of the National Gelatin Production Specification.

The following raw materials can be used for gelatin production: (1) the skin and bones of fresh cattle, pigs, sheep and other livestock that have passed quarantine provided by slaughterhouses, meat factories, canning factories, vegetable markets, etc.; (2) Before the tanning process, the sheared skin with raw edge or the inner layer of skin under the cut, commonly known as raw skin, two-layer skin, three-clear skin and other raw skins; (3) Clean bones processed by the bone processing plant and directly purchased natural air-dried aggregates.

The use of the following raw materials is prohibited: (1) any waste material after tanning in the tannery; (2) The skin and bones of cattle, pigs, sheep and other livestock without inspection and quarantine certificates.

In addition, there are strict regulations on the production environment of edible gelatin, and at present, some manufacturers do not follow the requirements and use substandard raw materials to cause gelatin heavy metals to exceed the standard.

One can be eaten, and the other cannot be eaten.

Edible gelatin is a hydrolysate of collagen, which is a fat-free and high-protein, cholesterol-free, and natural nutritious food thickener. After consumption, it will neither make people gain weight nor cause a decrease in physical strength. Gelatin is also a strong protective colloid, with strong emulsifying power, and can inhibit the coagulation of milk, soy milk and other proteins caused by gastric acid after entering the stomach, thus facilitating food digestion.

Industrial gelatin is widely used in various products in plates, furniture, matches, feed, packaging, papermaking, textiles, silk, printing and dyeing, printing, ceramics, petroleum, daily chemicals, coatings, metallurgy and other industries, and mainly plays the role of thickening, stabilizing, coagulation, blending, glazing, sizing, bonding, water fixing, etc. Industrial gelatin, a fine chemical, is a gelatin product divided according to the different uses of gelatin. In daily life, people divide gelatin into edible gelatin, medicinal gelatin, photographic gelatin, and industrial gelatin.

Among them, for industrial gelatin, it is divided into skin glue, bone glue, as well as hot melt powder, protein glue, feed glue, and match glue. Wait a minute.

To put it simply, industrial glue is made of industrial raw materials, and chemical products and food are made from food, such as starch.

It is clear that one is for industry and one for food.

There are many industrial gelatin impurities, many of which are harmful to the human body!

Gelatin can be divided into four categories: photographic, edible, medicinal, and industrial. (1) Edible gelatin is made of pigs, cows, mules, horses, skins (except other animal skins) through impurities, disinfection, steaming to form juice gelatin products.

Then dehydrated, manufactured to form rubber strips, films, powder granules (generally commonly used powder granular glue). 2) Medicinal gelatin is a high-grade gelatin product that is easy to be absorbed by the human body by using animal skin, bones and tendons through complex physical and chemical treatment. It has the physical characteristics of high viscosity, high freezing force, and easy freezing.

Industrial gelatin is mainly used in plywood, gauze, sand, printing, adhesives, etc.
