Example Embodiment

[0025] Example 1

[0026] First: firstly activate the probiotic bacteria to make the probiotic bacteria mud, then add the same weight of composite freeze-drying protection agent to the probiotic bacteria mud, mix well and pre-freeze at -40 ℃ for 8 hours, and then move it to the freeze dryer Freeze-drying for 20-24h to obtain freeze-dried probiotic bacteria powder;

[0027] Wherein, the composite freeze-drying protective agent is composed of 30% skimmed milk powder, 20% trehalose, 2% glutamic acid, 1% glycerol and 47% pH 6.5 citric acid buffer by mass percentage;

[0028] The preparation of probiotic bacteria mud is to make the number of viable bacteria of the bacteria powder as 1.0×10 10 -2.0×10 11 cfu / g Lactobacillus acidophilus was activated in MRS liquid medium, and the microscopic examination and OD value were determined to confirm that there were no impurities. After the OD value was >0.5, it was activated for three times, and then it was connected to a 10L fermenter an...

Abstract

The invention discloses a preparation method of synbiotic goat milk powder, which comprises the following steps: activating probiotics to obtain probiotic mire; adding a compound freeze-drying protective agent; obtaining freeze-drying probiotic powder by freeze-drying; carrying out purification, standardization and reduced pressure condensation on a raw material of goat milk to obtain new raw material of goat milk; adding prebiotics in the condensed raw material of goat milk and then carrying out spray drying to obtain goat milk powder containing the prebiotics; cooling the goat milk powder to room temperature and filtering with a screen; and mixing the screened goat milk powder containing the prebiotics with the probiotic powder under the aseptic condition to obtain the symbiotic goat milk powder. In the invention, the prebiotics are added into condensed degrease goat milk by condensation or whole goat milk and are beneficial to the uniform dispersion of the prebiotics; the probiotics are prepared by a freeze-drying method and added with the freeze-drying protective agent, so that the viable bacteria is more and bacteria has a colony of over 1,010cfu/g; and by adding the prebiotics into the goat milk powder, the prebiotics can be protected and the survival rate of the prebiotics and the functionality of the goat milk powder can be improved.

Description

technical field [0001] The invention relates to a preparation method of functional goat milk powder, in particular to a preparation method of synbiotics goat milk powder containing prebiotics (Prebiotics) and probiotics (Probiotics). Background technique [0002] Goat milk is rich in high-quality proteins and fatty acids such as albumin and globulin, which play an important role in human health, as well as various minerals. It has good health care and therapeutic effects on patients with malabsorption syndrome. Goat milk has small fat globules (only 1 / 3 of milk), and is rich in medium and short-chain unsaturated fatty acids that are beneficial to the body's direct utilization, with a high absorption rate. In addition, the rich calcium in goat milk products can help the body burn fat and promote the body to produce enzymes that degrade fat. Studies have shown that goat milk contains 15% more calcium than cow’s milk and five times more calcium than human milk. Goat milk is r...
