Abstract

The invention discloses an emulsion gel in which fat-soluble vitamins are embedded and a production method based on a pulse electric field. The production method includes the following steps: dissolving octenyl succinic acid modified starch in water, heating in a water bath, stirring until the material is completely gelatinized and dissolved, and cooling to room temperature; adding edible oil in which fat-soluble vitamins are dissolved to obtain a mixed solution; using a high-speed shearing machine and a high-pressure homogenizer to shear and homogenize the obtained mixed solution so as to a coarse emulsion; adding starch into the coarse emulsion, and uniformly stirring to obtain an emulsion; adding a methylcellulose solution to the emulsion, uniformly mixing and performing pulse electricfield treatment, heating in a water bath, degassing, and cooling to obtain an emulsion gel. The pulsed electric field of the invention promotes the interaction between methylcellulose and starch molecules, has a higher elastic modulus, and is easier to form a network structure that is more favorable for embedding fat-soluble vitamins. Thereby, fat-soluble vitamins are effectively embedded, and thepurpose of slowly releasing fat-soluble vitamins is achieved.

Description

technical field [0001] The invention relates to a method for embedding fat-soluble vitamins, in particular to a method for producing emulsion gel embedding fat-soluble vitamins by using a pulse electric field, which belongs to the technical field of food engineering. Background technique [0002] Fat-soluble vitamins are a general term for a class of polyprene compounds composed of long hydrocarbon chains or condensed rings. They can be divided into vitamin A, vitamin D, vitamin E, and vitamin K. They play a role in regulating the growth and development of organisms. , plays an important role in the process of metabolism. However, most fat-soluble vitamins cannot be synthesized or synthesized in insufficient amounts in the body, and must be ingested from the daily diet. However, fat-soluble vitamins are organic compounds with large molecular weight, insoluble in water, difficult to disperse, and difficult to absorb by cells in the body, which greatly limits their applicatio...
