A method of reducing a concentration of formaldehyde in an aqueous solution containing formaldehyde, hydroxyacetaldehyde and other sugar carbonyls is provided. The method includes adding an amino acid to the aqueous solution and maintaining the aqueous solution at a temperature for a duration sufficient for the formaldehyde and the amino acid to react according to a Maillard reaction to produce a final concentration of formaldehyde and a final concentration of hydroxyacetaldehyde in the aqueous solution. The final concentration of formaldehyde is substantially lower than an initial concentration of formaldehyde and the final concentration of hydroxyacetaldehyde is not substantially lower than an initial concentration of hydroxyacetaldehyde. An aqueous solution and a method of browning a foodstuff are also provided.

To provide a method for improving the body taste-imparting effect of a γ-glutamyl peptide. By using an edible oil/fat composition that is produced by dispersing an aqueous solution of a γ-glutamyl peptide in an oil/fat, the body taste-imparting effect of the γ-glutamyl peptide is improved.

A fruit juice beverage that contains: (a) a high-intensity sweetener in an amount equivalent to a sweetness intensity of X1; and (b) an amino acid, a derivative thereof, or a salt thereof exhibiting taste perception below the taste perception threshold. A sweet taste of sweetness intensity X3 is produced as a result of containing components (a) and (b), and 0.1<X1<X3 is satisfied.

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.
