摘要:
The present invention relates to a method for producing a fermented food or drink product, including: adding a strain of lactic acid bacteria which belongs to Lactobacillus brevis to a medium containing 50% or more by mass of a vegetative raw material, and either 0.2 to 2.0% by mass of malic acid or 2.0 to 20.0% by mass of fructose, the medium having a pH of 5.0 to 7.0, and the content of the vegetative raw material being expressed by a content thereof in its natural state; and performing fermentation at least until the termination of a logarithmic growth phase of the strain of lactic acid bacteria, wherein an acid or a strain of lactic acid-producing bacteria is additionally added to the medium at any point in time from the initiation of the fermentation until the termination of the logarithmic growth phase, so as to perform the fermentation with a rate of pH reduction of the medium being 0.01 to 0.3 (1/hour) during a time from the initiation of the fermentation until the termination of the logarithmic growth phase, and with a pH of the medium being 3.3 to 4.6 at the time the fermentation is completed.
摘要:
The present invention provides fermented food or drink obtained by fermenting a medium which includes vegetative raw material, by using Lactobacillus brevis, and the number of living cells of the Lactobacillus brevis in obtained fermented product is 1×108 cfu/ml or greater. The number of living cells does not significantly change after being preserved at 10° C. for three weeks, and excellent taste and flavor of the fermented food or drink do not deteriorate. The method for producing the fermented food or drink product includes the steps of: adding a strain of Lactobacillus brevis to a medium having an adjusted pH of 4.6 to 7.0, which includes: a vegetative raw material in an amount of 50% or more converted to a juice thereof; and 0.2 to 2.0% by mass of malic acid or 2.0 to 20.0% by mass of fructose, to ferment the medium so that the pH thereof becomes 4.3 or greater and less than 7.0; and adjusting a pH of a fermented product to 3.3 to 4.1 by using an acid.
摘要:
A method for manufacturing a drink made from beans as a raw material and a solid fermented food. It is characterized in that it comprises the steps of: preparing a stabilized suspension by homogenization-treating an aqueous slurry of whole grain-mash of beans once or a plurality of times using a homogenizer; denaturing protein by adding a coagulant and/or a pH adjustor to the stabilized suspension; and performing the dispersing treatment for making the relevant protein denaturation raw material dispersed by a physical dispersing means. In a solid fermented food, it comprises a step of fermenting for fermenting/solidifying by adding a lactic bacterium starter following the step of performing a homogenization treatment, and manufactures it via the step of maturating it if it is necessary.
