Abstract: The present disclosure discloses a preparation method of porous starch for encapsulating probiotic, and belongs to the field of food processing. The present disclosure provides porous starch with controllable pore size and morphology by regulating the ratio of amylose to amylopectin (quantitative compounding), keeping starch hydroxyl sites exposed (concentration cultivation), and building interfacial tension to stretch starch chains (convection drying), and uses the porous starch to encapsulate probiotics, which can improve the retention rate of probiotics, reduce the loss of probiotics during food processing and transportation, and thus retain the biological functions of probiotics to a maximum extent.

Abstract: Provided are a lycium barbarum leaf polysaccharide rich in galacturonic acid and a preparation method and use thereof. The method includes: mixing a lycium barbarum leaf and an acetone aqueous solution to obtain a mixture, and performing a fading treatment on the mixture to obtain a faded lycium barbarum leaf; extracting the faded lycium barbarum leaf with a chelating agent solution to obtain an extract solution; subjecting the extract solution to an alcohol precipitation with ethanol to obtain an alcohol precipitate; and subjecting the alcohol precipitate to an alcohol washing, a water redissolution, a dialysis and a drying in sequence to obtain the lycium barbarum leaf polysaccharide rich in galacturonic acid.
