The invention provides konjac fermented food and beverage and a preparation method thereof, and relates to the technical field of food and beverage
processing. The preparation method comprises the following steps: preparing konjac fluid, preparing primary seed fluid, preparing secondary seed fluid, inoculating and fermenting, and preparing a finished product. The konjac fermented food and beverage have the advantages that
konjac glucomannan (KGM) is high molecular
polysaccharide, has an effect of promoting growth of
bifidobacterium of human intestinal tracts, so that the structure of intestinal
flora can be effectively improved.
Lactic acid bacteria are
normal flora of a
human body, and the probiotics represented by the
lactic acid bacteria is necessary to the
human body, and are
beneficial bacteria with critical physiological functions, so that animal growth can be promoted,
normal flora of gastrointestinal tracts can be regulated, the micro-ecological balance can be maintained, the
gastrointestinal tract functions can be improved, body
immunity is improved. Carbon sourced substances are required when
lactic acid bacteria ferment,
starch is the
carbon source for growth and
metabolism of microorganisms, and 10 to 30 percent of the konjac is
starch, so that the konjac can be effectively used as the carbon sourced substance in
lactic acid bacteria
fermentation. Therefore, the content of effective components of konjac is taken, and the process of lactic acid bacteria
fermentation is introduced, so that the konjac fermented food and beverage can be a perfect combination of the two advantages technologically.
