The present invention provides a dried fish fermentation process and a starter culture development technology. A mixed starter culture including Bifidobacterium species, Lactobacillus acidophilus, Lactobacillus casei, Streptococcus thermophilus and Bifidobacterium lactis is prepared for the mixed fermentation of a dried fish; and salt content in the dried fish is controlled to control a proportional relation of flora in the mixed starter culture and to optimize the fermentation process, thereby preparing more fresh and delicious, fishy-free, more soft and delicate dried fish. Therefore, the dried fish is more popular with consumers.

A biotechnological composition, more specifically, a composition and its specific application at a Stick water Evaporation Plant during the fish meal & oil manufacturing process, aimed to avoid increase of nitrogen volatile compounds and to reduce the viscosity of stick water concentrate is disclosed.

The disclosure relates to a preparation method of eel polypeptide flavor extract, the eel polypeptide flavor extract, and the eel sauce. The preparation method of the eel polypeptide flavor extract includes the following steps: obtained by using eel processing by-products, eel cutting off the main meat tissues, successively performing microbial fermentation, Maillard reaction and extraction and separation processes. The eel polypeptide extract obtained above is used to making a condiment eel sauce. The eel sauce is nutritious and convenient, it can be used directly for table eating or served as cooking condiments to enhance the aroma and taste of dishes and increase the attractiveness of dishes. The disclosure realizes a new technological research on the preparation of polypeptide and flavor products, opens up a scientific utilization and processing method of seafood processing by-products, and provides a new way for making full use of such resources.

The present invention relates to a method for fermenting fish skin by using Aspergillus. Also provided is a use of the fermentation liquid obtained by fermenting fish skin with Aspergillus obtained from the method in inhibiting the activity of tyrosinase, inhibiting the activity of angiotensin-converting enzyme and/or improving the survival of fibroblasts.

An oil- or fat-processed starch, exhibiting a solubility of equal to or higher than 9.5% by mass and equal to or lower than 45% by mass, and an emulsifying capacity of equal to or higher than 50% and equal to or lower than 100%.

The present invention contemplates the creation of a low fluoride crustacean oil processed from a phospholipid-protein complex (PPC) formed immediately upon a crustacean (i.e., for example, krill) catch. Further, the crustacean oil may also have reduced trimethyl amine and/or trimethyl amino oxide content. The process comprises disintegrating the crustaceans into smaller particles, adding water, heating the result, adding enzyme(s) to hydrolyze the disintegrated material, deactivating the enzyme(s), removing solids from the enzymatically processed material to reduce fluoride content of the material, separating and drying the PPC material. Then, using extraction with supercritical CO.sub.2 or supercritical dimethyl ether, and/or ethanol as solvents, krill oil, inter alia, is separated from the PPC. In the extraction the krill oil can be separated almost wholly from the feed material.

The present invention discloses Planococcus and a method for improving fermentation quality of a low-salt fish sauce by Planococcus, and relates to the application field of food microbiology technology. The Planococcus strains have been deposited in China General Microbiological Culture Collection Center (CGMCC) under CGMCC NO.17057, CGMCC NO.17058, CGMCC NO.17059, and CGMCC NO.17060. The production cycle of fermented fish sauce using the Planococcus strains is greatly shortened, and the fermentation temperature is reduced. The fish sauce obtained by this method is transparent brown red, and has the unique aroma of aquatic products without impurities such as suspension or flocculent. The finished fish sauce has low salt content and high amino acid nitrogen content (according to the Chinese fish sauce industry standard, the fish sauce is classified as first-grade fish sauce). The contents of total volatile basic nitrogen and histamine are lower than the national standard.

The present disclosure is directed to methods for the formation and production of renewable muscle and/or fat primary cell lines, immortalized cell lines, and stem cell lines from shrimp, prawn, crab, crayfish, and/or lobster species and the cell lines themselves as well as human and animal consumable meat products produced therefrom.
