Use of transglutaminase

Glutamine transaminase (TG), also known as transglutaminase, is a monomeric protein acyltransferase with an active center composed of 331 amino groups and a molecular weight of about 38,000

TG has the following characteristics

Secondly, the pH value stability is good

In addition, thermal stability is strong

At the same time, it is safe to use

TG is used to produce new protein foods, which can improve food texture

Second, improve the nutritional value of protein

Third, a heat-resistant and water-resistant film is formed

TG also has some properties, such as cross-linking to protein macromolecules through lysine molecules, protecting lysine in food from damage in various processing processes; for embedding lipids and fat-soluble substances, it can make protein Forms a heat-resistant and water-resistant film; after TG treatment, no heat treatment is required in the process of protein gel formation

Classification of plant extracts

In recent years, as natural food has been respected in the world, plant extracts have become the star of food raw materials, showing strong growth momentum in the global market

Plant extracts use plants as raw materials.

There are many types of plant extracts, and there are many ways to classify them

According to the content of active ingredients, it can be divided into three types: effective monomer extract, standard extract and ratio extract; It can be divided into vegetable oil, extract, powder, lens, etc.

　　There are the following categories of plant extracts that are currently popular internationally

　　The main components of plant extracts include: alkaloids, that is, plant alkaloids, which are important active ingredients of Chinese herbal medicines, such as berberine in Coptis chinensis and ephedrine in ephedra; flavonoids, which have antioxidant and other biological activities, common Flavonoids include soybean isoflavones, anthocyanins, tea polyphenols, etc.

　　As the society pays more and more attention to food and drug safety, a large number of plant extracts that are safe to eat and have certain nutritional functions have been used as raw materials to make nutritional functional foods and health foods into people's lives in various ways
