Abstract

The invention discloses a starch octenylsuccinate-zein compound and a preparation method thereof. The starch octenylsuccinate-zein compound is prepared by performing winding and packing on the surfaceof starch octenylsuccinate with zein. According to the starch octenylsuccinate-zein compound disclosed by the invention, the characteristics that the zein can dissolve in an ethanol solution of 60%-95%, but cannot dissolve in water or anhydrous ethanol are utilized, firstly, the zein dissolves in an ethanol solution of 80%, and then the ethanol is evaporated by a rotating steaming instrument, sothat the zein is gradually separated out on the surfaces of SSOS granules to form an SSOS-zein compound. Through the preparation method disclosed by the invention, the characteristics of solubility, emulsibility, heat stability, viscosity and the like of the obtained SSOS-zein compound are changed, so that when the compound is applied to foods, some unique processing characteristics and some unique functional characteristics can be given to a food system, the quality of the products is improved, and the functions of improving the processing technology and the like can be achieved, and the application range of a starch-protein copolymer in industry is extended.

Description

technical field [0001] The invention relates to a starch octenyl succinate-zein compound and a preparation method thereof, belonging to the technical field of grain processing. Background technique [0002] The trade name of starch octenyl succinate is pure gum, and it generally exists in the form of sodium starch octenyl succinate (Starch Sodium Octenyl Succinate, SSOS). It is prepared by esterification reaction of hydrophobic octenyl succinic anhydride (Octenyl Succinic Anhydride, OSA) and starch milk under weakly alkaline conditions. SSOS is different from other modified starches because it introduces a hydrophilic group and a hydrophobic group 1:1 on the basis of the molecular structure of the original starch, which makes SSOS have excellent emulsifying properties in water-oil systems. In addition, after modification, its viscosity increases, its gelatinization temperature decreases, and its antifreeze performance is also improved. Therefore, SSOS is widely used in food...
