Yoghourt containing seaweed oil and making method of yoghourt

Abstract

The invention discloses yoghourt containing seaweed oil and a making method of the yoghourt, and belongs to the technical field of food processing. The making method comprises the following steps of (1) taking 4-6 parts of oligosaccharide and 71-76 parts of purified water, and after the oligosaccharide completely dissolves, adding 0.3-1.0 part of seaweed oil so as to make seaweed oil sugar medium fluid; (2) adding 9-12 parts of milk powder and 0.05 part of pectin to the seaweed oil sugar medium fluid obtained in the step (1), and performing sufficient and uniform mixing so as to obtain raw milk containing the seaweed oil; (3) performing sterilization on the raw milk containing the seaweed oil, obtained in the step (2), at 85 DEG C for 15 minutes; (4) cooling the sterilized raw milk obtained in the step (3) to about 40 DEG C, inoculating 10 parts of a lactic acid bacteria fermenting agent under aseptic conditions, and performing fermentation at 40 DEG C for 6-8 hours; and (5) immediately enabling the temperature of the fermented yoghourt obtained in the step (4) to 4-6 DEG C, performing after-ripening for 12-16 hours, and performing packaging so as to obtain finished products. According to the yoghourt and the making method thereof disclosed by the invention, a reasonable formula is optimized, and a production technology is improved, so that the yoghourt has excellent peculiar flavor and extremely high nutrient value, is rich in DPA, DHA and EPA, has obvious effects on the respects of preventing cardiovascular diseases, reducing blood lipid, reducing cholesterol, restraining the growth of tumors and the like, and is a green healthy health-care food conforming to the trend of the times.

Description

technical field [0001] The invention belongs to the technical field of food processing, and specifically relates to yoghurt containing seaweed oil and a preparation method thereof. Background technique [0002] The world's seaweed resources are abundant, and the world's seaweed can provide an annual output of 300 billion tons. Seaweed in the ocean grows fast, has high photosynthetic efficiency, and is mostly asexual reproduction and has strong adaptability.
