Nutritious corbicula fluminea juice and preparation method thereof

Abstract

The invention discloses a nutritious corbicula fluminea juice and a preparation method thereof and relates to the technical field of preparation methods of corbicula fluminea juices. Shelled corbicula fluminea meat is mixed with water and subjected to homogenizing treatment to obtain corbicula fluminea meat paste, the corbicula fluminea meat paste is subjected to high-pressure pulsed electric field-ultrasonic composite treatment to obtain an initial corbicula fluminea juice, and then a dynamic complex protease is adopted for carrying out enzymolysis operation to obtain a concentrated corbicula fluminea juice; the concentrated corbicula fluminea juice is subjected to centrifugation and sterilization operation under a non-thermal pulse electric field to obtain the nutritious corbicula fluminea juice. Not only can the processing added value of corbicula fluminea be increased, the product type of the corbicula fluminea is enriched, but also industrial upgrading can be promoted, and the market competitiveness of products is improved. In addition, the nutritious corbicula fluminea juice obtained by means of the method not only is rich in nutrients such as amino acid, polypeptide and polysaccharide, clear and bright in appearance and unique in flavor but also has high in-vitro anti-oxidation activity.

Description

technical field [0001] The invention relates to the technical field of preparation methods of clam juice, and specifically designs a nutritional clam juice and a preparation method thereof. Background technique [0002] River clam (Cobicula flaminca) is a bivalve mollusc, belonging to the class Phallobranches, the order Eulamybranches, the family Clamidae, and the genus Clamidae. It is one of the important economic shellfish in my country. River clams are rich in nutrients such as protein, essential amino acids, vitamins and trace elements, and also have some biologically active substances such as functional polypeptides and polysaccharides, which have high edible value for maintaining human health. In addition, it is recorded in "Compendium of Materia Medica" that "clams mainly cure appetizers, suppress Danshi drug poison, remove violent heat, improve eyesight, facilitate urination, relieve alcohol poisoning, and treat yellow eyes"; among the people, river clam soup is rega...

Problems solved by technology

[0004] Although many scholars at home and abroad have introduced some production methods for the extraction and processing of clam meat, the current enzymatic hydrolysis process involves the control of the concentration of the substrate, and only through the mechanical homogenization process of clam meat, it is impossible to completely extract the clam meat. The protein and other high molecular compounds in the clam meat, thus causing the waste of river clam meat

In addition, the enzymatic hydrolysis process is limited by the type of protease and the enzymatic hydrolysis conditions, and it is impossible to completely enzymatically hydrolyze the clam protein, and usually the enzymatic hydrolysis process often takes more than 6 hours. The long-term enzymatic hydrolysis process will be accompanied by some oxidizable substances. Degradation and enzymatic browning and other processes occur, thereby reducing the nutritional value and sensory quality of the clam extract

In addition, with regard to the clam extract, it is usually a single product of protein or polysaccharide, which cannot comprehensively utilize the multiple nutrients in the clam meat. Through subsequent multiple purification, separation operations and spray drying, it not only increases the processing of the product process and processing costs and further reduces the nutritional value of the clam extract
