The invention relates to the technical field of microbial
polysaccharide preparation, and in particular relates to a preparation method of a compound
curdlan paste preparation. The method comprises the following steps: preparing a
nutrient solution, preparing an
emulsion, preparing a compound gel solution, preparing a compound
curdlan block, preparing a compound
curdlan paste, and preparing the curdlan paste preparation; and the finally obtained compound curdlan paste preparation includes the following components in percentages by weight: 15-35% of
vegetable oil, 1.5-3.5% of a
nutrient solution, 0.7-1.5% of a pH
regulator, 2-20% of a
water activity regulator, 0.25-3.5% of a
redox potential
regulator, 0.5-1.5% of a functional protective agent, 0-0.05% of a food
preservative, and the balanceof the compound gel solution. According to the method, a
microstructure of curdlan is transformed through the process, the
water holding properties of the curdlan is improved, the curdlan can wrap water-soluble
nutrient substances, the nutrient value of the curdlan is improved, the improvement of the
water holding performance is conducive to better play of functionality of
glucan in the curdlan,and suspension properties of the substances wrapped by the curdlan are improved.
