Embodiment 1

[0028] Example 1: Making donkey-hide gelatin and jujube yoghurt with whole milk powder

[0029] ① Raw material pretreatment

[0030] Donkey-hide gelatin is selected from Exian County, Shandong Province, which requires dark brown, smooth cross-section, hard and brittle texture, slightly fragrant gas, and slightly sweet taste. Bake donkey-hide gelatin at 120°C for 30 minutes, take it out and let it cool, and crush it to a fineness of more than 150 mesh to obtain donkey-hide gelatin powder for later use;

[0031] For red dates, choose red-skinned jujubes with uniform particles, no rot, no pests and diseases, good maturity, small nuclei and lots of meat. Arrange the red dates to remove impurities and pits; put them in an oven, bake them at 120°C for 30 minutes, take them out to cool, and crush them to a fineness of more than 150 mesh to obtain red date powder for later use;

[0032] Reconstitute the whole milk powder with warm water at 45°C. According to the mass ratio of whole ...

Embodiment 2

[0036] Example 2: Making donkey-hide gelatin and jujube yoghurt with fresh milk

[0037] ① Sterilize the fresh milk at 90°C for 10 minutes, cool it down, and set aside. Under aseptic conditions, 3% of fresh milk mass was inoculated with Streptococcus thermophilus and fermented for 8 hours to form yogurt.

[0038] ② Blend jujube powder and warm water at 50°C in a mass ratio of 1:5. After blending, filter the juice through a filter cloth, sterilize at 90°C for 5 minutes, and cool to obtain jujube juice.

[0039] ③According to the mass ratio of donkey-hide gelatin powder and water 1:10, soak donkey-hide gelatin powder in hot water to dissolve, stirring continuously during the process, after it is completely dissolved, filter, add 6% white sugar, sterilize at 90°C for 10 minutes, cool to 42°C, under aseptic conditions, inoculate the activated Lactobacillus helveticus (Lactobacillus helveticus) in an amount of 3%, put it into a constant temperature fermentation box (tank) at 42°C ...

Embodiment 3

[0042] Fresh milk to make donkey-hide gelatin red date yogurt

[0043] ①②③ Same as Example 1

[0044] 4. get the above-mentioned 84.5% weight yoghurt made above, 10% weight jujube juice, 5% weight first fermented donkey-hide gelatin juice and 0.5% weight starch (commercially available), blend and mix, stir with homogenizer, Cool and refrigerate at 3°C ​​for 18 hours to obtain liquid donkey-hide gelatin red date yoghurt.

Abstract

The invention relates to a production method of donkey-hide gelatin small peptide red date yoghurt. The production technique comprises the following steps of: (1) pre-treatment of raw materials; and (2) preparation of the donkey-hide gelatin red date yoghurt, which comprises the steps of: inoculating Streptococcus thermophilus into whole milk powder or fresh milk for ferment to form the yoghurt; preparing red date powder into date juice; preparing donkey-hide gelatin powder into primarily fermented donkey-hide gelatin juice; and mixing the yoghurt, the date juice, the primarily fermented donkey-hide gelatin juice and a stabilizing agent, homogenizing, cooling, refrigerating for 12-24 hours at 1-6 DEG C to manufacture the donkey-hide gelatin red date yoghurt. The invention has unique low-cost donkey-hide gelatin small peptide fermentation production method and a simple and practical production technology. The product of the invention is novel health-care yoghurt which has the nutrient value of the yoghurt as well as the health-care value of donkey-hide gelatin small peptide red dates.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a process of fermenting donkey-hide gelatin with Lactobacillus helveticus and then mixing and fermenting it to produce donkey-hide gelatin small peptide jujube yoghurt, which belongs to the technical field of health food and its production method Background technique [0002] With the development of medicine, physiology, and biology, people's living standards continue to improve, and a new concept of health care - the health care concept of probiotics has emerged. "A glass of milk strengthens a nation", the Chinese government has encouraged students to drink a glass of milk every day since 1998. Lactobacillus helveticus is a probiotic that produces acid and aroma. It can produce a variety of amino acids and bioactive peptides during the production of fermented yogurt. Bioactive peptides have the physiological function of improving human metabolism, are easy to digest and absorb, a...
