Preparation method of pig blood plasma protein powder

Abstract

The invention provides a preparation method of pig blood plasma protein powder, wherein the method comprises the following steps: step A, inputting pig blood to a first rotary drum of a centrifugal machine and performing primary centrifugal separation by a preset first centrifugal inertia force; step B, inputting the primarily-separated pig blood to a second rotary drum of the centrifugal machine, and performing final centrifugal separation by a preset second centrifugal inertia force to obtain pig blood plasma; step C, ultra-filtering the pig blood plasma by a semipermeable membrane; step D, drying the pig blood plasma obtained after final separation to obtain the plasma protein powder. By utilizing secondary centrifugation of different centrifugal inertia forces, damages of the pig blood cells during centrifugation are reduced and the quality of the pig blood plasma is improved; by further adopting an ultrafiltration method, impurities such as ash content of the pig blood plasma are reduced, and the purity of a final finished product is improved; besides, by adopting the ultrafiltration method, the water content of the blood plasma can be reduced as well, so that the energy consumption caused in subsequent drying operation is reduced, the cost is lowered and the drying time is shortened.

Description

technical field [0001] The invention relates to the technical field of animal plasma processing, in particular to a method for manufacturing pig blood plasma protein powder. Background technique [0002] Because of its high medicinal value and low price, pig blood is widely used in the production of medicines. For example, pig blood is used as raw material to extract protein, heme, immunoglobulin and SOD enzyme, and different health foods can be prepared respectively, which have the functions of easy digestion and absorption, blood enrichment, immunity enhancement and anti-aging. Pig blood is very rich in nutrients, known as "liquid meat". According to measurements, every 100 grams of pig blood contains 19 grams of protein, which is higher than the content of beef, lean pork and eggs; the fat content is very small, only 100 grams per 100 grams Contains 0.4 grams, so pig blood is a low-calorie, low-fat, high-protein food; in addition, pig blood contains essential inorganic s...
