Abstract

Goat milk method for disinfection disclosed by the invention belongs to the technical field of milk products sterilization, in order to solve the unsolved always for many years goat milk sterilization difficult problem of people, a kind of method that comprises several sections soft heating processes is proposed, at first make sheep breast temperature slowly rise to 95 ℃, through 200MPa pressure homogeneous, be heated to 105 ℃ again, and kept 33 seconds, then be heated to 115 ℃, and kept for 4 seconds, reduce to 80～10 ℃ at last rapidly, do not contain bacterium in the goat milk that makes like this, soft the coagulating of lactalbumin changed, be easy to absorb, and the vitamins loss is few, only is 4%～5%, and fat and albumen are near free of losses.

Description

A kind of goat milk method for disinfection

Technical field

The present invention relates to a kind of milk products method for disinfection, more particularly, the present invention relates to a kind of goat milk method for disinfection.

Background technology

The nutrition of goat milk is suckled near the people.The dry of goat milk, protein, amino acid, fat, mineral matter, vitamin are all suckled similar in the people.That goat milk albumen forms is less, fat globule is little, soft and even, be easy to human consumption and absorb.Particularly immunoglobulin content is higher in the goat milk, thereby goat milk more approaches people milk, is easier to the baby and drinks.Goat milk is considered to the best substitute of breast milk since ancient times.Much told tales such as Yang Shi wet nurse are arranged.

Goat milk has the good characteristic of skin care, beauty treatment.Active factors in the goat milk-epithelical cell growth factor EGF can promote human epithelial cell ground to grow up fast, form new cell, the most of cell of human body is activated by it all, drink or wash epithelial cell aging, downright bad with all repairing fast, wearing and tearing, promote skin elasticity to form, make skin-whitening health, and recover normal physiological function, the effect that skin maintenance is arranged and delay senility.So Gu has the record of " often drinking goat milk, look such as virgin ".

Goat milk is the desirable dairy products of the elderly.The calcium that ratio is fit to, phosphorus play an important role to the prevention senile osteoporosis, the goat milk cholesterol is low to have the certain significance to reducing cardiovascular and cerebrovascular diseases and hypertension incidence rate, the cephalin in the goat milk fat and the content of nucleotides is than milk height, and the elderly is increased intelligence and to recover brain function helpful.It is low that the elderly also has benefited from goat milk acidity, and softer curdled milk and good buffer capacity can be improved the digestive system function, prolong life.

Goat milk is the not anti-disease person's of milk best dairy products.Phenomenons such as abdominal distension, diarrhoea, vomiting can take place during milk drink in 25% colony, are called as " lactose intolerance ".Lack the digestion lactase in the human body, milk forms grumeleuse in stomach and intestine, nondigestible.Drinking goat milk does not just have this phenomenon, and easily the goat milk of digestion, good absorbing is the not anti-disease person's of milk best milk beverage.

The sterilization technology of milk is very ripe in China.But goat milk is because unstable characteristics such as its fat, albumen, SCFA, acidity are solved the sterilization technology of goat milk for many years, and the suitability for industrialized production of liquid goat milk and milk have a great difference, and its difficulty, complexity are considerably beyond the processing of milk.This also can't see the major reason of goat milk product just on the market.

At present the suitability for industrialized production of the liquid goat milk of China fails to move towards the right path always, and main cause is that the sterilization technology of goat milk fails to obtain to break through.

Summary of the invention

The present invention has proposed a kind of effective goat milk method for disinfection in order to solve the difficult problem of the unsolved always goat milk sterilization technology of people for many years.

Concrete technical scheme is as follows.

The goat milk method for disinfection that the present invention proposes may further comprise the steps:

(1) preheating: goat milk is preheating to 75～85 ℃ with 50～60 seconds;

(2) heat up: be warming up to 95 ℃ with 95～100 seconds goat milk with preheating;

(3) homogeneous micronization: with homogenizer goat milk is carried out homogeneous under the pressure of 200MPa, make the lipochondrion that contains in the goat milk be broken for 0.01～0.02 μ m;

(4) constant temperature: will heat goat milk will be warming up to 105 ℃, and 105 ℃ of following constant temperature 33 seconds;

(5) heat up: with 115～125 seconds goat milk is warming up to 115 ℃ behind the constant temperature, and is incubated 4 seconds down at 115 ℃;

(6) cooling: with 115～125 seconds the goat milk temperature is reduced to 100 ℃, be cooled to 20～25 ℃ with frozen water through 48 seconds then, be cooled to 8～10 ℃ through 48 seconds more at last.

The classical process for sterilizing of cow's milk is heated to 137～140 ℃ for through very long heating process, keeps 4～6 seconds, passes through very long temperature-fall period again, reduces to normal temperature at last.Cow's milk is through behind this sterilization process, vitamins loss 10～50%, protein passivation and lose whole activity, in the fat originally the few unrighted acid of content with total loss.If the sheep breast carries out sterilization by this technology, then the sheep breast will become the state as jellied bean curd, and the sheep breast not only loses its item property but also will lose its whole nutrients like this.

The particularity of method for disinfection of the present invention is through above several sections soft heating processes, make sheep breast temperature slowly rise to 95 ℃, through 200MPa pressure homogeneous, make sheep Ruzhong lipochondrion be broken into 0.01～0.02 micron, make inside and outside the bacillus cell membrane because huge pressure differential and fragmentation causes its death from original 2-3 micron.Again through being heated to 105 ℃, keeping making in 33 seconds that lactalbumin (particularly lactoglobulin and lactoalbumin) is soft changes, makes its easier digesting and assimilating with fixed attention.At last the sheep breast is heated to 115 ℃, kept for 4 seconds, residual thermo-responsive bacterium is killed reached commercial sterilization.Vitamins loss is few than the cow's milk sterilization process in the sterilization overall process, only is 4%～5%.Fat, albumen are near free of losses.Put into practice by nearly 3 years field, market with the product that this bactericidal assay is produced, proved the validity of this method for disinfection.

The specific embodiment

Following mode with embodiment is further explained the present invention.

Embodiment 1

The goat milk method for disinfection that the present invention proposes may further comprise the steps:

(3) homogeneous micronization: with homogenizer goat milk is carried out homogeneous under the pressure of 200MPa, make lipochondrion wherein be broken for 0.01～0.02 micron;

(4) constant temperature: will heat goat milk will be warming up to 105 ℃, and 105 ℃ of following constant temperature 33 seconds;

(5) heat up: with 120 seconds goat milk is warming up to 115 ℃ behind the constant temperature, and is incubated 4 seconds down at 115 ℃;

(6) cooling: with 120 seconds the goat milk temperature is reduced to 100 ℃, be cooled to 20～25 ℃ with frozen water through 48 seconds then, be cooled to 8～10 ℃ through 48 seconds more at last.
