The disclosure relates to a strain of high-temperature sensitive S. pastorianus and application thereof and belongs to the technical field of microorganisms. In the disclosure, the S. pastorianus Pilsner is mutagenized by ARTP, based on the principle that yeast intracellular alkaline phosphatase reacts with BCIP to produce blue precipitates, screening of high-temperature sensitive mutant strains can be carried out according to the appearance time and shade of the blue, and finally a strain of high-temperature sensitive S. pastorianus P-510 is obtained after screening and quickly autolyzed at 37° C. Autolysis of P-510 at 37° C. can promote the dissolution of autolysates to obtain highly flavored nucleotides, glucan and antioxidant active substances, which can be used for production of S. pastorianus autolysates with high nutritional values.

A flavour composition is provided. The composition includes a characterizing citrus flavour and a taste modifying composition. The taste modifying composition includes at least two aliphatic amino acids; at least one additional amino acid selected from the group consisting of acidic, basic, aromatic, hydroxylic and mixtures thereof; at least one organic acid; at least one sugar and at least one mineral.

A solid flavour composition includes a plurality of individual components at least one of which is a flavour-providing substance and at least one of which is an auxiliary ingredient, in which all amorphous components are present as particulate aggregates. The flavour composition is particularly storage-stable.

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.
