Problems solved by technology

At present, the extraction of pig placental polypeptide is mainly by enzymatic hydrolysis, which has a low extraction rate, long enzymatic hydrolysis time, and the problem of microbial contamination during the enzymatic hydrolysis process. The use of pepsin and alkaline protease is very corrosive to equipment and is not conducive to industrial production.

Embodiment 1

[0041] 1 kg of fresh pig placenta is washed and crushed to obtain minced pig placenta. Add 5kg of water to the minced meat, stir evenly, and then add 25g of compound enzyme to obtain a mixed solution. The ratio of the compound enzyme is trypsin:papain:flavor protease=1:1:2. Vacuum-pack the mixed solution into two bags, then sterilize by irradiation on one side with a radiation dose of 6 kGy, and then perform an enzymatic hydrolysis reaction at 45°C for 20 hours to obtain an enzymatic hydrolysis solution. Finally, the enzymolysis solution is filtered and then spray-dried to obtain porcine placenta polypeptide powder.

Embodiment 2

[0043] 1 kg of fresh pig placenta is washed and crushed to obtain minced pig placenta. Add 3kg of water to the minced meat, stir evenly, and then homogenize at 10000r / min for 2min to obtain a homogeneous liquid. Put the homogeneous liquid into the subcritical equipment to decompose for 60min, the subcritical condition is 130°C, 1Mpa. Add 10 g of compound enzyme to the subcritically decomposed pig placenta fluid to obtain a mixed solution, and the ratio of the compound enzyme is trypsin:papain:flavor protease=2:1:1. The mixed solution was vacuum-packed into two bags, and then sterilized by irradiation on both sides with a total irradiation dose of 6 kGy, and then enzymatically reacted at 37° C. for 8 hours to obtain an enzymolyzed solution. Finally, the enzymolysis solution is filtered and then spray-dried to obtain pig placenta powder.

Embodiment 3

[0045] 1 kg of fresh pig placenta is washed and crushed to obtain minced pig placenta. Add 10kg of water to the minced meat, stir evenly, and then homogenize at 5000r / min for 5min to obtain a homogeneous liquid. Put the homogeneous liquid into the subcritical equipment to decompose for 30min, the subcritical condition is 150℃, 0.5Mpa. Add 20 g of compound enzyme to the subcritically decomposed pig placenta fluid to obtain a mixed solution, and the ratio of the compound enzyme is trypsin:papain:flavor protease=2:1:2. The mixed solution was vacuum-packed into 4 bags, and then sterilized by double-sided irradiation with a total irradiation dose of 6 kGy, and then enzymatically reacted at 50° C. for 4 hours to obtain an enzymolyzed solution. Finally, the enzymolysis solution is filtered and then spray-dried to obtain pig placenta powder.

Abstract

The invention provides a method for producing pig placenta polypeptide, which belongs to the technical field of food processing. In the present invention, the pig placenta is firstly washed and crushed to obtain minced pork placenta; then the minced pig placenta is mixed with water 2 to 10 times the weight of the minced pig placenta to obtain a minced meat liquid; then the minced meat liquid is mixed with 0.5%~ Mixing compound enzymes with 10% pig placental minced meat mass to obtain a mixed solution; the mixed solution is vacuum-packed, irradiated and sterilized, and then enzymatically hydrolyzed for 4 to 24 hours to obtain an enzymatic hydrolyzate; then the enzymatically hydrolyzed solution is centrifuged and filtered to obtain the above supernatant; finally, the supernatant is spray-dried to obtain the porcine placenta polypeptide. The method provided by the invention has high yield, short cycle and no pollution, and the pig placenta polypeptide prepared by the method of the invention can be developed into functional drinks and health products, and the polypeptide product has light fishy smell and positive color.

Description

technical field [0001] The invention relates to the technical field of food production, in particular to a method for producing pig placenta polypeptide. Background technique [0002] Placenta, also known as "Ziheche", is a special functional tissue organ. Modern biological and medical research proves that pig placenta contains biologically active peptides, immunoglobulins, amino acids, minerals, cytokines, growth factors, phospholipids, polysaccharides, etc. "Compendium of Materia Medica" records: placenta "warm in nature, sweet and salty, enters the lungs, liver, and kidneys, has the effects of calming the nerves and nourishing blood, nourishing qi, benefiting essence, detoxification, and enriching blood. It has a peculiar effect, long-term use can improve hearing and eyesight, blacken the beard, prolong life, and have the effect of taking away the good fortune." Therefore, whether it is from the perspective of modern medicine or traditional Chinese medicine, pig placent...
