Problems solved by technology

[0002] my country is a country rich in pig blood resources, but it lags behind many developed countries in the development and utilization of pig blood resources. Because the simply processed pig blood protein is not easy to digest and absorb, has a darker color, a strong bloody smell and poor palatability, it has been used for a long time , a lot of pig blood is poured into the ditch as waste, which not only causes huge waste, but also pollutes the environment;
[0003] Domestic processing of pig blood is whole blood drying, poor palatability due to the bloody smell of pig blood itself, poor digestibility due to the blood cell structure of pig blood itself and the destruction of amino acids by high temperature during the drying process, and poor balance of amino acid composition, blood meal The content of crude protein and the total amount of amino acids are extremely high, but the ratio of leucine and isoleucine in pig blood itself is out of balance, resulting in low nutritional value of cooked pig blood meal produced by traditional methods

Embodiment 1

[0036] Embodiment 1, with reference to figure 1 , one A processing technology for spray-drying porcine plasma protein powder, comprising the following steps;

[0037] Step 1. Acceptance of qualified pig blood;

[0038] Pig blood from qualified slaughterhouses is transported by vehicles, and the temperature of the pig blood to the factory must meet the original blood acceptance standards, and a quarantine certificate must be provided;

[0039] Step two, primary filtration;

[0040] Put a 40-mesh filter in the filter tank to filter the pig blood to remove impurities;

[0041] Step 3, anticoagulation cooling storage;

[0042] Add anticoagulant to the pig blood and mix evenly, then put it into a storage tank for storage within 12 hours, and control the temperature below 20°C through a refrigeration unit;

[0043] The anticoagulant is sodium hydroxide and sodium citrate, and the anticoagulant needs to check the compliance of the packaging and the label every time it arrives a...

Abstract

The invention relates to the technical field of processing of agricultural foods and in particular relates to a processing technology of spray-dried pig plasma protein powder. The processing technology comprises the following steps: step 1, checking qualified pig blood; step 2, carrying out primary filtering; step 3, resisting coagulation, cooling and storing; step 4, centrifuging and separating;step 5, concentrating; step 6, carrying out spray-drying; step 7, sieving; step 8, checking and accepting packaging materials; step 9, packaging, storing and transporting. According to the processingtechnology provided by the invention, the production of the processing of a slaughter house and the processing of livestock and poultry byproduct blood are linked and combined, so that the processingefficiency is improved and the safety of original blood is ensured; unqualified pig blood can be filtered again to be qualified through secondary checking and acceptance of the pig blood; the wastes of the pig blood are avoided and the environment pollution is avoided; plasma and blood cells can be separated through centrifuging and separating, and the plasma and the blood cells are subjected to spray-drying to obtain the plasma protein powder; the quality of the plasma protein powder is improved.
