Description
Affiliated technical field
The invention belongs to technical field of dairy processing, be specifically related to a kind of can be at liquid goat's milk of normal temperature condition long preservation and preparation method thereof.
Technical background
Goat Milk comprehensive nutrition, function uniqueness are described as " unique food that can compare favourably with breast milk " by international nutrition circle, China carried out deep research to Goat Milk very early, and gave very high evaluation.Put down in writing according to Compendium of Material Medica: " the sweet temperature of sheep milkiness is nontoxic, profit cardiopulmonary, tonifying lung kidney qi ".Modern trophic analysis shows: the lipochondrion volume of goat milk is 1/3rd of a milk, and the content of the protein in the goat milk, mineral matter, especially calcium, phosphorus is all than milk height; Vitamin A, B content also are higher than milk.Compare with milk, goat milk is easier to be digested and assimilated.Particularly be more suitable for suffering from allergy, gastrointestinal disease, bronchitis or weakly crowd and infant and the elderly drink.Goat milk contains epithelial cell growth factor (EGF), and tunica mucosa bronchiorum is had repair, and goat milk contains 20 multiple nutrients materials and biologically active growth factor, and it both can satisfy people's nutritional need, can protect the health of skin again.Goat milk is called " natural antibiotics " by some national nutritionists of West Europe, because the immunoglobulin content height of goat milk, immunoglobulin (Ig) is elimination virus effectively, and the protection human body preserves from, and especially diseases such as tuberculosis and respiratory tract is had better curative effect.As seen, the exploitation Goat Milk is significant for the nutrition and health levels that improve the numerous both urban and rural residents.
5,400,000 of the existing milch goats of China, more than 270 ten thousand of the existing milch goats in Shaanxi, it is over half to account for the whole nation, but present situation is in that can't see on the market can be at the liquid goat's dairy products of long preservation under the normal temperature condition (more than 1 month).This is because the distinctive smell of mutton of Goat Milk itself, ordinary consumer is difficult for accepting, while is because of the special construction of Goat Milk, raw material milk more is subject to germ contamination and acid change corruption at ambient temperature, particularly protein in the goat milk and reduced sugar under ultra-high temperature condition (cow's milk processing go up sterilization time be called UHTS) with 135 ℃-150 ℃ sterilization temperature and 2-8 second interacting produces brown stain, layering, rotten, have (72 ℃-75 ℃ of cow's milk pasteurizes now and adopt, 15-20 second) method, can not kill the bacillus in sheep Ruzhong, cause product under normal temperature condition, to be preserved after 10 days, just putrid and deteriorated because of bacterial reproduction.Therefore, Goat Milk is difficult to be processed to for a long time can be at the liquid goat's milk of long preservation under the normal temperature condition, had a strong impact on drinking and remote sale of universal Goat Milk, cause Goat Milk mainly to be sold by processing milk powder nearby, not only reduced the nutritive value of goat milk to a great extent, and directly caused the goat milk purchasing price low, deficiency in economic performance.
Summary of the invention
The present invention to provide a kind of can be at the liquid goat's milk of long preservation under the normal temperature condition and preparation method thereof, can not provide the present situation that can under normal temperature condition, preserve the liquid goat's dairy products with what overcome that prior art exists.
For overcoming the problem that prior art exists, technical scheme of the present invention is: a kind of can be at the liquid goat's milk of long preservation under the normal temperature condition, comprise following raw materials by weight percent, Goat Milk 93%～95.5%, pure goat milk powder 4%～6.5%, Goat Milk stabilizing agent 0.15%～0.25%, milk products flavor enhancement 0.1%～0.3%.
The preparation method of above-mentioned normal temperature liquid goat's milk with long preservation period comprises the steps: successively
(1) Goat Milk obtaining and checking
