Abstract

Disclosed is a method for preparing anti-oxidation probiotic goat milk powder by means of mist-spraying drying. The method comprises the steps that skimmed milk powder, sucrose, glucose, trehalose, gelatin and glycerin are dissolved in distilled water separately to obtain respective solutions, and the solutions are sterilized and cooled to a room temperature; the skimmed milk powder, sucrose, glucose, trehalose, gelatin and glycerin solutions are added into goat milk after fermentation is completed, mixed evenly and homogenized to obtain anti-oxidation probiotic goat milk; the anti-oxidation probiotic goat milk is subjected to mist-spraying drying under the conditions that the diameter of a spraying nozzle is 1 mm, the air inlet temperature is 130 DEG C and the feeding flow is 4.5 ml / min,and the anti-oxidation probiotic goat milk powder is obtained. According to the method, the skimmed milk powder, sucrose, glucose, trehalose, gelatin and glycerin solutions are added into the anti-oxidation probiotic goat milk and serve as heat-resistant protection agents, so that the viable count and survival rate of lactobacillus casei in the process of preparing the goat milk by means of mist-spraying drying are increased.

Description

technical field [0001] The invention relates to a preparation method of goat milk powder, in particular to a method for preparing anti-oxidative probiotic goat milk powder by spray drying. Background technique [0002] my country's goat milk is rich in resources and has distinctive characteristics. A large number of studies have confirmed that goat milk is rich in protein, amino acids, vitamins, minerals and fat. Its composition is the closest to that of breast milk. It enjoys the reputation of "the king of milk" in the world. Compared with cow's milk, goat's milk has the following characteristics: fat and protein particles are smaller, and the human body is easy to digest and absorb; it contains 8 kinds of amino acids necessary for the human body; there are a large number of immune factors and active polypeptides, which are beneficial to improve immunity; Growth factor (EGF) can promote the repair of skin and mucous membranes, superoxide dismutase (SOD) can play a role in s...
