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: A metal/?-MoC1-x load-type single-atomic dispersion catalyst, a synthesis method therefor, and applications thereof. The catalyst uses ?-MoC1-x as carrier, and has metal that has the mass fraction ranging from 1-100% and that is dispersed on carrier ?-MoC1-x in the single atom form. The catalyst provided in the present application can be adapted to a wide alcohol/water proportion in hydrogen production based on aqueous-phase reforming of alcohols, outstanding hydrogen production performance can be obtained at a variety of proportions, and catalysis performance of the catalyst is much higher than that of metal loaded with an oxide carrier. Especially when the metal is Pt, catalysis performance of the catalyst provided in the present application in the hydrogen production based on aqueous-phase reforming of alcohols is much higher than that of a Pt/?-MoC1-x load-type catalyst on the ?-MoC1-x carrier on which Pt is disposed on a layer form in the prior art.
