  • Publication number: 20220411839
    Abstract: The present invention provides a method of preparing a sorbitol liquid and a liquid polyol using a maltitol raffinate. The method includes the steps of: obtaining a saccharification liquid by adding glucoamylase to the maltitol raffinate for saccharification; obtaining a fermentation liquid by adding a dry yeast to the above saccharification liquid for fermentation; obtaining the sorbitol liquid and the liquid polyol by performing decolorization filtration and membrane separation for the above fermentation liquid. The present invention can fully utilize the maltitol raffinate to increase its added value. Further, the method is simple, practical and low in costs.

  • Publication number: 20220071251
    Abstract: The present invention relates to a method for improving sensory attributes of a sugar alcohol and application thereof. After analyzing the difference between the sugar alcohol used as a sugar substitute and sucrose in multiple sensory attribute dimensions by flavor analysis, corresponding taste modifying substances are added according to the intensity of the difference, thereby solving the problem that there are differences between the sugar alcohol used as a sugar substitute and the sucrose in taste sensory attributes in the field of food at present. According to the invention, the taste difference between the sugar alcohol and the sucrose in multiple sensory attribute dimensions is analyzed, so that the level of taste improvement is broader. Multidimensional accurate quantification of differences is realized by means of a sensory flavor wheel, thereby realizing accurate taste modification and improving the accuracy of taste improvement.
