bloom gelatin | The composition and function of gelatin What

Gelatin is one of the most important natural biopolymer materials and has been widely used in food, medicine and chemical industries. Gelatin plays a very important role in a variety of dairy products. It can prevent whey separation during yogurt review and improve the organization and stability of the finished product. In sour cream, it can achieve good appearance, taste and texture. Gelatin also plays an important role in stabilizing many dairy products, optimizing product appearance and taste, and improving tissue state.

What is the composition of gelatin

The main composition of gelatin is a mixture of polypeptide molecules with the same amino acid composition and a wide molecular weight distribution. The molecular weight is generally tens of thousands to hundreds of thousands. Gelatin is both acidic and alkaline. It is an amphoteric substance. The micelle of gelatin is charged. Under the action of an electric field, it will move to one of the two poles. The molecular structure of gelatin has a large number of hydroxyl groups, in addition to many carboxyl groups and amino groups, which makes gelatin extremely hydrophilic.

What is gelatin made of

Gelatin is made from animal skin and bone through more than ten processes including classification, washing, leaching, degreasing, neutralization, hydrolysis, filtration, concentration, gelation, drying, and crushing. It is a tasteless and translucent , Hard flakes, granules or powder. The production process includes acid method (A type), alkali method (B type), and a very few adopt enzymatic method. Gelatin is a polymer of peptide molecules and a multi-level hydrolysate of collagen. It is widely used in food, medicine and other industrial fields. Edible gelatin is a food additive with high nutritional value. It can be directly made into thick soup, meat jelly, canned meat, crystal jelly, salad, egg yolk juice, icing sugar, butterscotch, flavored sauce, chocolate, beverages, etc. Beer, etc.; photographic gelatin is used to make photosensitive materials such as film and film; medicinal gelatin can be used to produce medicinal hollow capsules, gelatin sponges, etc.; industrial gelatin can be used to produce grinding wheels, emery cloth, matches, and printing rubber rollers. What does gelatin do

Gelatin has three main functions in dairy products: preventing the precipitation of whey, gelatin successfully prevents the precipitation of whey through the formation of hydrogen bonds, avoiding the shrinkage of casein, thus preventing the solid phase from separating from the liquid phase; emulsification stabilization , Casein itself is a natural emulsifier and stabilizer, but casein will lose its emulsifying ability and stabilizing ability in an acidic environment, while gelatin can provide stable conditions for casein and act as a protective colloid; a stabilizer for milk foam , All milk foam can be regarded as an emulsification system of air fat water. Gelatin as a hydrophilic colloid combines with water to form a thin layer of gelatin to cover the fat globules and wrap the air bubbles to reduce the influence of external conditions on the air pressure in the air bubbles. Stabilize the role of foam, thereby maintaining a stable emulsified state.

Gelatin development history

At present, my country's gelatin industry is in a period of rapid development, and the market capacity is rapidly huge. The statistics of Zhiyan Consulting Research Department show that the market capacity of my country's gelatin association industry has increased from 2.86×10^4t in 2005 to 6.32×10^ in 2010. 4t. Among them, the market capacity of bone gelatin increased from 1.80×10^4t in 2005 to 3.46×10^4t in 2010. Data show that the national dairy product output in 2013 was 26,980,298, and the national dairy product output was 10,434,302.76 tons from January to May 2014. Due to the large output of China’s dairy products, for the gelatin in dairy products, with the large-scale production of dairy products, The demand for gelatin in dairy products will continue to grow.

According to the "In-depth Development Research of China's Gelatin Industry from 2020 to 2025 and the "14th Five-Year" Enterprise Investment Strategic Planning Report" from the China Research Institute and Puhua Research Institute:

Analysis of China's Gelatin Market Scale

my country’s gelatin industry is developing rapidly, and the market capacity is expanding rapidly. Opportunities and difficulties exist. Foreign-funded enterprises are expanding rapidly in China, and the development of national enterprises is squeezed. At the same time, domestic gelatin enterprises are small in scale and uneven in product quality. The industrial technology is relatively backward and so on. According to statistics, the size of China's gelatin market was 403 million yuan in 2009, and the market size increased to 1.426 billion yuan in 2017.

In the past five years, the growth of the international gelatin market according to its purpose is that medicinal gelatin has the fastest growth rate, reaching 10%, which matches the growth rate of the world pharmaceutical industry; edible gelatin has a larger base, followed by a growth rate. Reached 2.4%; while the share of photographic gelatin in this field is gradually reduced due to the popularization of digital photography technology, which is reduced by 2.4%. With the integration of the world economy, the development trend of my country's gelatin industry segmentation market is basically the same as that of the international market. Pharmaceutical gelatin and high-end edible gelatin manufacturers will usher in more development opportunities and greater development space.

According to forecasts, by 2024, the market size of the gelatin industry in North China will reach 519 million yuan, the market size of Northeast China will reach 312 million yuan, the market size of East China will reach 1.244 billion yuan, and the market size of South China will reach 453 million yuan. The regional market scale will reach 503 million yuan, and the western region market will reach 612 million yuan
