Abstract

The invention belongs to the field of abalone peptides, and discloses an abalone peptide and a production method thereof. The production method of the abalone peptide comprises the following steps: pretreating abalones, carrying out enzymolysis by using a high-efficiency compound enzyme preparation under the conditions that the pH value is not adjusted and the temperature is not controlled, filtering by using an inorganic nanofiltration ceramic membrane to remove components which are difficult to dissolve and easy to absorb moisture, carrying out high-temperature high-pressure treatment on a peptide solution, concentrating, and drying to prepare powder. By adopting the method provided by the invention, the pH value of enzymolysis does not need to be adjusted, the enzymolysis temperature does not need to be controlled, the enzymolysis time is short, the enzyme addition amount is small, the molecular weight of an enzymolysis product is low and concentrated, and the prepared abalone peptide powder is excellent in water re-solubility and not prone to moisture absorption and caking in a storage process.

Description

technical field [0001] The invention belongs to the field of abalone peptides, in particular to an abalone peptide and a production method thereof. Background technique [0002] Known as the "king of seafood", abalone has been one of the "eight treasures" of seafood since ancient times. Abalone belongs to a kind of primitive marine shellfish, there are 216 species in the world, and it has high nutritional value and medicinal value. Abalone has always been a traditional and precious food in China. It is recorded in "Compendium of Materia Medica" that abalone is sweet in taste and flat in nature. "eye fish". There are also records about abalone in "Pharmacopia", "Bielu of Famous Doctors" and "Huangdi Neijing". With the in-depth research on abalone, the value of abalone is also recognized by modern medicine. It is rich in protein, glycogen, various amino acids, vitamins, trace elements and other physiologically active substances. Abalone contains an average of 19.0 grams of...
