Abstract

The present invention discloses a low-fat fermented dairy product and a preparation method thereof. The method comprises the steps of: (1) mixing and stirring a component A and 0-5% of collagen peptide, performing secondary homogenization, performing sterilization, cooling to get a liquid A; mixing and stirring a component B and 0-5% of collagen peptide, performing secondary homogenization, sterilizing to get a liquid B; wherein the component A and the component B respectively comprises 20-60% of low-fat milk and 0.1-1% of a thickener; the total amount of collagen peptide is 2-5% and the molecular weight is 2000-6000 daltons; and total amount of low-fat milk is 70-95%; (2) inoculating fermentation bacteria in the liquid A, keeping warm for fermentation, and cooling; and (3) mixing and stirring a fermented milk base material and the liquid B, and performing sterile secondary homogenization. The invention also discloses application of collagen peptide in a low-fat fermented dairy product. The low-fat fermented dairy product of the present invention is beneficial to bone health and beauty, good in taste, moderate in viscosity, and suitable for daily diet and long-term consumption of general population of all ages.

Description

technical field [0001] The invention relates to the field of dairy products, in particular to a low-fat fermented dairy product and a preparation method thereof, and the application of collagen peptides in the low-fat fermented dairy product. Background technique [0002] Collagen is the most abundant and widely distributed protein in the human body. It is mainly distributed in the connective tissue of the human body, and is very important for the formation of human skin, blood vessels, bones and cartilage and the maintenance of their elasticity. Collagen is abundant in the body of higher animals, accounting for about 1 / 3 of the total protein. 75% of the dermis of the skin is composed of collagen, and the growth, repair and nutrition of the skin are inseparable from collagen. 70-80% of the organic matter in bones is collagen, which plays an important role in bone health, promotes the deposition of calcium in bones, and effectively prevents osteoporosis. Collagen is one of ...
