Problems solved by technology

[0004] In recent years, there are a lot of literatures on the research on the functional activity of polypeptides. Domestic and foreign studies have shown that walnut peptides prepared by enzymatic hydrolysis of walnut protein have the functions of anti-oxidation, improving immunity, anti-fatigue, lowering blood pressure and improving learning and memory. Peptides Combining with oil can enhance its function of lowering blood pressure and improving learning and memory, but its application in functional foods is limited due to the insolubility of peptides and oils
[0005] Application numbers 201310485124.9, 200810236514.1 and 201310655750.8 all describe the process of preparing walnut peptides, and all adopt the method of participating in the enzymolysis process with various proteases. The solution process is not ideal, thus affecting the quality of walnut peptide
[0006] The patent with application number 201310655750.8 introduces a technology for microencapsulating walnut peptides, using sodium carboxymethyl cellulose and β-cyclodextrin as excipients to microencapsulate walnut peptides, and the carboxymethyl cellulose used There are more plain sodium, which increases the sodium ion of the product, so the obtained walnut peptide microcapsules are not conducive to the taking of hypertensive patients

Abstract

The invention relates to fat-soluble walnut peptide and a preparation method thereof. The preparation method includes the following steps sequentially: washing walnut meal, removing impurities, performing protease gradient enzymolysis, filtering, embedding with a fat-soluble wall material, and performing centrifugal separation and drying to obtain the fat-soluble walnut peptide. The fat-soluble walnut peptide and the preparation method thereof have the advantages that sodion ingestion reduction of people due to the fact that carboxymethyl cellulose sodium is used as the wall material in the prior art is avoided, products are more healthy, and quality of the walnut peptide is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of polypeptide preparation and deep processing, and in particular relates to a preparation method of fat-soluble walnut peptide. Background technique [0002] Walnut, also known as walnut and Qiang peach, is one of the four famous dried fruits in the world. The medicinal value and nutritional value of walnuts are very high, containing a lot of protein, unsaturated fatty acids, vitamins, minerals, etc. It is an excellent dry nut food for the brain, and is regarded as a good product for longevity by medical scientists and health preservation. Walnut kernels are very rich in nutrition. Every 100 grams of walnut kernels contain 63.7g of high-quality fat, 14.6g of protein, 10.3g of carbohydrates, 280mg of phosphorus, 85mg of calcium, 2.6mg of iron, 3.0mg of potassium, 0.036mg of vitamin A, and vitamin B 1 0.26mg, vitamin B 2 0.15mg, niacin 1.0mg, nicotinic acid 1.0mg, in addition to manganese, chromium and oth...
