Problems solved by technology

Trotters also contain nutrients such as vitamins A, B, C, calcium, phosphorus, and iron, especially after the protein in trotters is hydrolyzed, the contents of 11 kinds of amino acids such as cystine and arginine produced are comparable to those of bears. There are many kinds of nutritious food made from trotters on the market, but most of them are stewed or fried products, and too much nutrition is lost during the production process.

Embodiment Construction

[0011] 1) Shave and wash the trotters, mix and mince fresh hawthorn, vinegar, and water in a ratio of 1:2:10 to obtain a mixed juice. Add a food-grade pH regulator to the mixed juice to make the pH of the mixed juice For 6-7, mix the bromelain, lipase, and mixed juice at a ratio of 1:2:80, stir evenly to obtain the enzymatic hydrolysis juice, put the trotters into the enzymatic hydrolysis juice, and enzymatically hydrolyze at 50-54℃ 12-15 hours;

[0012] 2) Put the enzymatically hydrolyzed trotters in a steamer and steam for 30-35 minutes;

[0013] 3) Deboning the steamed pig's feet, pulverize the pig's feet skin into 80-90 mesh granules, and dry the pig's feet powder once with a spray drying tower. The temperature of the inlet air for the first drying is controlled at 170-190 degrees Celsius and discharged The temperature is controlled at 70-80 degrees Celsius;

[0014] 4) Place the dried trotters powder on room temperature for 5-7 days;

[0015] 5) Use spray drying tower to dry th...

Abstract

The invention relates to pig foot albumen powder and a preparation method thereof. According to the pig foot albumen powder and the preparation method thereof, disclosed by the invention, fresh pig feet are used as raw materials, and enzymolysis is performed on the pig feet, so that nutrient components of the pig feet are easy to absorb by human bodies, and the fragrance of the meat quality of the pig feet is improved; spray drying is performed once, spreading, water absorption and softening are performed, and then redrying is performed, so that the water content of the pig feet powder is low, and the pig feet albumen powder can be stored for one year without going bad at a normal temperature; a food additive and a preservative do not need to be added, so that the nature of the pig feet powder can be ensured, and the nutrition efficacy of the pig feed is furthest exerted.
