The invention belongs to the field of
food processing, and particularly relates to a method for accumulating pineapple
pomace polyphenol through a high-
voltage pulsed
electric field combined
fermentation technology. The method comprises the following steps:
drying pineapple
pomace to constant weight, mixing the
dried pineapple pomace with water, firstly treating the pineapple pomace by a high-
voltage pulsed
electric field, destroying the pomace
cell structure to release active substances under the action of the
electric field, then adding glucose into the obtained pineapple pomace
mixed solution, and sterilizing the pineapple pomace
mixed solution; after the
system is cooled, inoculating the sterilized pineapple pomace
mixed solution with a microbial complex
microbial inoculant, and fermenting to obtain a pineapple pomace product after the
fermentation is finished; and the microbial complex microbial inoculants are
saccharomyces cerevisiae and
lactobacillus plantarum JYLP-002. The method is green, energy-saving and suitable for large-scale production, the
utilization rate of the pineapple pomace is increased, the
flavor characteristic is improved on the basis that the
polyphenol content is increased and the
oxidation resistance is enhanced, and the method is an
effective method for efficiently utilizing the pineapple pomace and accumulating
polyphenol.
