Sugar-reduced red jujube haw slices

Abstract

The invention discloses sugar-reduced red jujube haw slices prepared from red jujubes and haws as raw materials, which is prepared by blending sugar-reduced fermented jujube powder with haw powder, granulating and tabletting. A preparation method of the sugar-reduced red jujube haw slices comprises the following steps: cleaning the haws, removing haw seeds, pre-boiling for softening, pulping, enzymatically hydrolyzing, homogenizing and spray-drying to obtain the haw powder; cleaning the fresh red jujubes, removing jujube pits, pulping, sterilizing, fermenting, drying and grinding to prepare the sugar-reduced fermented jujube powder; blending the haw powder and the sugar-reduced fermented red jujube powder with auxiliary materials, granulating and tabletting to prepare the sugar-reduced red jujube haw slices. According to the preparation method, gas producing yeasts are utilized to consume monosaccharides and oligosaccharides in a growth metabolism process to remove most of micromolecular saccharides in the jujube powder so as to reduce the total sugar content. The method has the advantages that the sugar-reduced fermented jujube powder is produced by consuming the oligosaccharides in the yeast fermentation growth process, and the total sugar content in the sugar-reduced red jujube haw slices is reduced by more than 25%, thus the sugar-reduced red jujube haw slices belong to sugar-reduced foods; the red jujubes are combined with the haws, and the nutritional ingredients in the red jujubes and the haws are retained; the preparation process is simple and convenient for factorization batch production.
