Abstract

The invention discloses stepped ultrasonic preparation of a protein-polysaccharide emulsion and functional food application, relates to the technical field of emulsion preparation, and in particular relates to a method for preparing a protein-polysaccharide compound emulsion by adopting a sequential stepped ultrasonic technology. Pectin is added into sodium caseinate, a protein-polysaccharide compound is constructed through electrostatic interaction, in the process of preparing the sodium caseinate-pectin compound, a stepped ultrasonic processing device is used for replacing heating, protein and polysaccharide are promoted to interact to form the compound through physical force formed by the cavitation effect of ultrasonic waves, and the physical and chemical structure of the compound is changed, so that the particle size of the compound is reduced by 10.2%, and the emulsibility is improved by 32.3%. The sodium caseinate-pectin compound emulsion is good in storage stability, the stability index is increased from 25.62% to 97.13%, the sodium caseinate-pectin compound emulsion is slightly influenced by environmental conditions such as temperature and pH, and the selection range of bioactive components is wider.

Description

technical field [0001] The invention relates to the technical field of emulsion preparation, in particular to a method for preparing protein-polysaccharide complex emulsion by using sodium caseinate and pectin as raw materials and adopting sequential step ultrasonic technology. Background technique [0002] Emulsions are dispersions in which one liquid is dispersed in the form of droplets in another immiscible liquid. In order to improve the stability of the emulsion, it is usually necessary to add emulsifiers or surfactants. Common emulsifiers are mainly divided into four types: anionic emulsifiers (such as oleic acid soap); cationic emulsifiers (such as dodecyl ammonium chloride); nonionic emulsifiers (such as long-chain fatty alcohol polyoxyethylene ethers) and amphoteric emulsifiers (such as proteins). Compared with traditional emulsions, emulsions prepared by relying on proteins, polysaccharides and other biological macromolecules to stabilize the oil-water interface ...
