Embodiment 1

[0030] A kind of oyster nutrition powder, described oyster nutrition powder obtains by following processing technology, and described processing technology comprises the steps:

[0031] (1) Raw material pretreatment: wash the oyster meat, remove the viscera, homogenize it with a high-speed tissue masher, and make oyster homogenate liquid according to the mass ratio of raw materials and water at 1:1-1:3;

[0032] (2) High-pressure homogenization: homogenize the oyster homogenate obtained in step (1) under a pressure of 30 MPa to 40 MPa, so that the oyster raw material becomes uniform and fine particles to obtain an oyster homogenate;

[0033] (3) Enzymolysis supplemented by ultrasound to prepare enzymolysis solution: the oyster homogeneous solution obtained in step (2) was enzymatically hydrolyzed with enzyme solution, pH 8.6-9.2, enzymolysis temperature 38°C-42°C, enzymolysis time 2h~4h; At the same time, ultrasonic treatment is carried out under the conditions of 20KHz~40KHz,...

Abstract

The invention provides a novel processing technique for oyster nutritious powder. The processing technique comprises the steps of raw material pretreatment, high-pressure homogenization, enzymolysis, ultrasonic treatment, spray drying and the like. According to the novel processing technique, the enzymolysis biochemistry and the physical technique are combined; compared with the traditional enzymolysis method, the processing technique has the advantages that the enzymolysis efficiency is improved; meanwhile, before enzymolysis, the high-pressure homogenization is improved, and the yield of the oyster nutritious powder is increased, so that the raw material utilization ratio is increased. The novel processing technique of oyster nutritious powder, which is provided by the invention, adopts a simple process; oyster nutritious powder obtained by ultrasonic enzymolysis contains rich nutritious ingredients such as protein, fat and polysaccharide, has multiple effects of blood pressure reduction, oxidation resistance and the like, is beneficial to absorption by human bodies, moreover, is good in solubility, is convenient to eat, is stable in product quality, and is beneficial to industrial production.

Description

technical field [0001] The invention belongs to the technical field of seafood processing, and in particular relates to a processing technology for preparing oyster meat nutrition powder with functions of lowering blood pressure and anti-oxidation by supplementing with ultrasound. Background technique [0002] Oysters, also known as oysters, oysters, oyster yellows, sea oysters, etc., belong to the mollusc phylum (Mollusca), and the clambranchs ( Lamelli branchia ), Oyster family ( Ostreidae ), is the world's largest cultured shellfish, and is also one of the main mariculture species in my country's coastal areas. In our country, it is mainly cultured. There are about 20 kinds of oysters produced along the coast, which are one of the four major cultivated shellfish. It is produced from the Bohai Sea, the Yellow Sea, the South China Sea to the Nansha Islands, mainly in Liaoning, Hebei, Shandong, Jiangsu, Zhejiang, Guangdong, Guangxi, and Hainan. my country's fishery stati...
