Abstract

The present invention discloses a preparation method of macadimia nut polypeptides. The preparation method of the macadimia nut polypeptides is extracting polypeptides from macadamia nuts by enzymolysis and comprises the following steps: a, crushing; b, suspension homogenizing; c, constant temperature enzymolyzing; d, boiling water sterilizing; e, centrifuging and separating; and f, freeze-dryingand macadimia nut polypeptide powder obtaining. By using an enzymolyzing method to prepare the polypeptides, a utilization rate of macadimia nut meal proteins is improved. The obtained polypeptides bythe method are more stable in properties and higher in yield than that treated by other drying methods. Due to the fact that the prepared macadimia nut polypeptides are low in molecular weight and good in product stability, the macadimia nut polypeptides have very good effects of preventing fatigue, lowering blood pressure reducing, preventing oxidation, etc.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing a macadamia nut polypeptide. Background technique [0002] Macadamia nuts are rich in nutrients. In addition to high fat, the nuts also contain quite high protein and carbohydrates, and are also rich in calcium, phosphorus, iron and B vitamins thiamine, riboflavin and niacin. Macadamia nut oil has a variety of health functions. The cake after oil extraction retains the complete nutrients of macadamia nuts and has high nutritional value. However, it is mainly used as feed now, resulting in a great waste of resources. The product macadamia nut meal contains high content of protein, glutamic acid, arginine, aspartic acid, leucine and lysine. Enzymatic preparation of peptides is one of the effective ways to improve the protein utilization of macadamia nut meal . Contents of the invention [0003] The technical problem to be solved by the present invention is ...
