Abstract: Disclosed is a method for regulating a porous structure and texture property of a freeze-dried pectin aerogel, which comprises the following steps of step 1: preparation of pectin/starch solution by mixing pectin powder and a gelatinized starch solution to form a stable pectin/starch mixed solution, a concentration of the pectin being 0.05% to 0.2% (w/v); step 2: induction of gel reaction by adding D-(+)-Glucono-?-lactone and calcium carbonate into the stable pectin-starch mixed solution; and step 3: vacuum freeze of the starch/pectin composite gel subjected to the gel reaction to obtain the freeze-dried pectin/starch aerogel with an adjustable porous structure and an improved texture characteristic. Controllable regulation of the porous structure of the freeze-dried pectin aerogel is achieved by the method without complex pretreatment. Raw material ingredients applied in the method are cheap, easy-to-access, and has low-toxicity.
