Mussel protein product and its production process

Abstract

The present invention belongs to the field of food technology, and is especially mussel protein product and its production process. The present invention provides one new type of protein product with the mussel clam as the side product of freshwater pearl shell as the main material and through alkali dissolution and acid precipitation. The production process includes leaching mussel clam in dilute alkali solution for 1-24 hr, centrifuging to obtain supernatant, regulating pH of the supernatant to isoelectric point to deposit protein, centrifuging separation to take precipitant, and drying to obtain mussel protein product. The mussel protein product is light yellow powder with protein content over 90 % and excellent functional characteristic, and may be used in food production.

Description

technical field

[0001] The invention belongs to the technical field of food, and specifically relates to a shellfish obtained by extracting and recovering its protein by using the by-products of the soft body of the freshwater pearl mollusk Hypophyllum sinensis as the main raw material by adopting the non-enzymatic dissolution method of "alkali-dissolving and acid-precipitating" Animal protein isolate products and methods for their preparation. Background technique

[0002] Protein is the material basis of life and the main raw material of the food industry. With the development of the modern food industry, there is an urgent need for a large number of protein products with high nutritional value and excellent functional properties as raw materials or additive base materials for the food industry. Therefore, it is particularly important to vigorously develop protein intermediate materials with excellent properties to make up for the existing deficiencies. Hyriopsis cumingii...
