Description
Technical field
Present invention relates particularly to a kind of pasteurize goat milk and preparation method thereof.
Background technology
Goat milk is nutritious, contains multiple nutritional components and bioactive substance.The fat ratio milk of goat milk is high, goat milk
Fat globule size is identical with people's milk, only 1/3rd of milk, can faster, more completely be absorbed by the body, will not cause
Fat accumulation, drink for a long time strong without getting fat.Although goat milk nutritive value is high, be easy to absorb, due to smell of mutton compared with
Weight, smaller in China market, development is limited.The smell of mutton of goat milk mostlys come from pollution and the internal chemical composition of external environment condition
Influence.Special sebaceous angle gap, the lipid of angle gap secretion on rear side of the angle bastem portion on milch goat head be present
The smell of uniqueness can be given out, pollution sheep breast, makes to contain smell of mutton in sheep breast.The fat that smell of mutton in goat milk also contains in itself with goat milk
Fat acid content is related, such as the content of acid, certain herbaceous plants with big flowers acid and octanoic acid in goat milk is usually 6-18%, and these aliphatic acid are in milk
In content be only 5%, although itself there is no any smell, because it can interact in goat milk, formed
Complex compound be combined with each other, so as to form smell of mutton.
The goat milk flavor removing technology in China mainly has following several at present：The de- mode of having a strong smell of smell doffing method, physics of beginning of production,
Chemistry de- have a strong smell mode, biological smell doffing method etc..Vacuumize degassing to flash, be a kind of de- mode of having a strong smell of physics, flash distillation is exactly high pressure
Saturation water enter low pressure container in, because the unexpected reduction of pressure makes these saturation waters become saturated steam.That is basis
Pressure declines, and the principle that solution boiling point declines carries out vacuum evaporation cooling, pumps bad smell.
The invention provides a kind of full-cream pasteurize goat milk and preparation method thereof, nutritious, smell of mutton is low, can low temperature length
Phase preserves.
