Description
Technical field
The present invention relates to the extractive technique field of wheat-germ oil, more particularly to a kind of rapid extraction side of wheat-germ oil
Method.
Background technology
Wheat-germ oil is a kind of grain germ oil produced by low-temperature extraction as raw material using wheat malt, it has concentrated small
The nutrition essence of wheat is rich in vitamin E, linoleic acid, leukotrienes, sweet eight carbon alcohol and a variety of physiological activity components, is the work(of preciousness
Energy food, has very high nutritive value.Especially content of vitamin E is the hat of vegetable oil, has been acknowledged as one kind and having had much battalion
Support the functional grease of health-care effect.With endocrine is adjusted, loses weight, prevents color spot, blackspot and pigmentation；Antioxygen is turned into
With, it reduces lipid peroxide and generates, promote moisture-retention function of skin, skin is made to moisten, anti-aging；It boosts metabolism and skin
Update, crease-resistant, wrinkle resistant, anti-skin aging eliminate scar；Regulating blood lipoid softens blood vessel, prevention of arterial hardening, hypertension, apoplexy
Effect.
Wheat plantule protein matter content accounts for about 30% or more, is 4 times of flour protein.Containing 8 kinds of amino needed by human
Acid, short lysine in especially general cereal, every 100 grams contain 205 milligrams of lysine, and tens are higher by than rice, flour
Times.Lysine can be effectively facilitated physical growth of children and development.The members such as calcic, iron, magnesium, zinc, potassium, phosphorus, copper, magnesium in wheat embryo
The element amount of seeing is relatively abundant, and iron-holder is at 12 milligrams or so in every 100 grams of wheat embryos, these trace elements are to promoting children growth hair
Give birth to important function.
Since wheat embryo oil content is low, extraction is difficult, and extraction rate is slow, that there is recovery rates is low for traditional squeezing method,
The shortcomings that nutrient component damages are more, high labor cost, not only also a large amount of impurity component, also result in the nutrition of embryo oil at
Divide and destroyed, the existing method that quickly preferably can extract wheat-germ oil has using supercritical carbon dioxide extracting
Method, but its extraction conditions requires height, and equipment is expensive, and production cost is high, not easy to operate, limits wheat embryo oil extract and promotes and answers
With.

Step 3：The cold press germ cake temperature that step 2 obtains is down to 23-25 DEG C, is later put into cold press germ cake
It is crushed in crusher；
Step 4：Cold press germ cake after being crushed in step 3 is put into cold pressing expeller, carries out secondary cold press, and obtain hair
Oil and cold press plumule muffin；Cold press pressure controls between 5-7MPa, and the control of cold press rotating speed exists：Between 35-40r/min, cold press
Temperature controls between 65-80 DEG C；
Step 5：By the crude oil obtained in step 2 and step 4 up to wheat-germ oil after precipitation, refined filtration processing.
Preferably, cold press pressure is in the step 2：4MPa.
Preferably, cold press rotating speed is in the step 2：34r/min.
Preferably, cold press temperature is in the step 2：80℃.
The present invention provides a kind of rapid extracting method of wheat-germ oil, and cold-squeezing is used to carry out oil to wheat embryo
The extraction of fat is by grease after being separated in raw material by the huge pressure of physical mechanical, and crude oil passes through multiple tracks physics mistake
It filters.It has merged the technologies such as modern high-tech filtering purification, has entire production process pollution-free, product natural nutrition
It is not damaged, reduces the process that steaming, stir-fry, leaching etc. increase oil yield, remain original bioactivity to a greater extent；In addition
Processing cost is low, and process is simple, is suitble to promoting the use of for wheat embryo oil extract.
