ANS: The ingredient of pine meat powder is papain, which is a cysteine protease existing in papaya fruit. Papain plays an important role in meat tenderization, which is often called pine meat powder in the market. Papaya milk is the main raw material for making pine meat powder.

Papain is commonly found in tender essence or loose meat powder on the market, and its application in food is mainly to soften meat quality. Usually, when you are in cook the meat, you add a little papaya, and the connective tissue and protein of the meat are decomposed by papain rich in papaya, which can make the meat taste more delicious, and you won't feel that the meat is too old to bite. The results showed that papain had obvious softening effect on cold-stored goat meat, with myofibrillar protein decreased from 9.93% to 7. 19% and meat pulp protein decreased from 5.34% to 2. 12%.

Supplementary explanation:

The component of natural pine meat powder is papain, which is called tender meat crystal. Its main function is to partially hydrolyze elastin and collagen in meat by protease, so that meat products taste tender but not tough, delicious and fragrant. Because of its fast tenderizing speed and obvious effect, it has been widely used in catering industry. After meat products enter human body, protein in meat is mainly decomposed into small units of peptides and amino acids by pepsin secreted by stomach and trypsin produced by pancreas.

Supplementary explanation:

The action principle of protease in tender meat powder is exactly the same as that of pepsin and trypsin, but the sources of protease in tender meat powder are different, one is in animals and the other is in plants. At present, the extraction of protease mostly comes from plant raw materials, such as papaya, ginger, pineapple and so on. Its name is generally based on the extracted raw materials, such as ginger, which is called ginger protease, and papaya is called papain. Taking papain commonly used in tender meat powder as an example, its processing technology is to cut immature papaya fruit, collect its milk, and then get papain through a series of processing, and then add a certain proportion of other accessories to make tender meat powder. According to the instructions of food additives, the formula of meat tenderizer is papain 2%, 15% glucose, monosodium glutamate 2% and salt. ,
