Abstract

The invention discloses low-ash donkey plasma protein powder. The low-ash donkey plasma protein powder is offwhite, powdered and odor-free; the ash content is less than or equal to 5 percent; the coarse protein content is larger than or equal to 83 percent; the immune globulin content is larger than or equal to 22 percent; the dissolving degree is larger than or equal to 96 percent; total volatile base nitrogen is smaller than 260mg/kg; the salt content is less than or equal to 3.5, the coarse ash content is less than or equal to 11.0, the water content is less than or equal to 9.0, the lysine content is larger than or equal to 3.5 percent, the coarse fiber content is less than or equal to 3.0, and the total phosphorus amount is 0.15-0.5; viruses cannot be detected. On the premise of killing the viruses and germs, the protein powder keeps the nutritional components in donkey blood to the maximum extent and is novel high-quality plasma protein powder. The invention also discloses a preparation method for the low-ash donkey plasma protein powder. According to the preparation method, all steps from raw material selection to finished product forming are implemented in a sterilized closed pipeline, so that pollution in a working process is avoided.

Description

technical field [0001] The invention belongs to the technical field of fresh donkey blood processing, and in particular relates to a low-ash donkey plasma protein powder and a preparation method thereof. Background technique [0002] my country's feed production ranks second in the world, but most of them are low-end products, and animal blood is a high-quality protein source. In the current livestock and poultry breeding, most of the blood goes bad and wastes, causing environmental pollution. Therefore, high-quality animal blood feed promotes the upgrading of the feed industry. With the increasing number of pets in our country, people are also pursuing high-protein and high-quality feed for pets. Nowadays, plasma protein powder is mostly made of pig blood. The Chinese patent application number 201010525103.1 discloses a pig plasma protein powder with low ash content. The preparation method of the invention is to prepare a new type of plasma protein powder by using pig bloo...
