Description

A kind of method utilizing water substitution preparing benne oil

Technical field

The present invention relates generally to a kind of method utilizing water substitution preparing benne oil.

Background technology

Sesame oil extraction technique existing at present mainly contains two kinds: a kind of is traditional being roasted through high temperature by sesame, then adopts water substitution or milling process to produce sesame oil; Another kind is in Preliminary Applications in the low-temperature cold pressing technique preparing benne oil produced.There are problems in traditional technology, as dark in sesame oil color and luster, poor transparency, and sesame protein serious degenerative or destruction, cause sesame-send cake and slag as cheap feed applications, can only cause the waste of a large amount of sesame protein resources; Although low-temperature cold pressing technique overcomes some traditional technology oil problem of wasting with albumen of poor quality, sesame oil productive rate is not high.

Extruding puffing utilizes fricative heat that material is heated up, and forces material by nib, obtain certain pressure simultaneously under the effect of extrusion spiral.After nib extruded by material, pressure sharply declines, and moisture evaporates, and internal batch forms vesicular structure, and volume increases, thus reaches expanded object.Utilizing extruding and puffing technology to carry out pre-treatment to oil plant, is the new technology that a kind of grease extracts.After oil plant is expanded, produce the capillary channel of many densifications therein, the quick infiltration for solvent is extracted grease and is provided passage, because cell walls is destroyed the gathering with grease in oil plant cell, creates favourable condition for carrying oil.Aqueous enzymatic extraction technology is a kind of efficient and ideal grease extractive technique, and grease extraction efficiency is high compared with water substitution, can also obtain quality protein simultaneously.Not enough for application aqueous enzymatic extraction sesame oil technical study at present, the people such as SajidLatif in 2011 adopt Protex7L to extract sesame oil, and extraction yield is up to 87.1%.Therefore, significant for aqueous enzymatic extraction sesame oil technical study.

patent of invention content

The technical problem to be solved in the present invention just, is to provide a kind of mild condition, extraction yield is high, sesame oil quality the is high method utilizing water substitution preparing benne oil.

For solving the problems of the technologies described above, the present invention adopts a kind of method utilizing water substitution preparing benne oil of following steps, comprises the following steps:

(1) screen: remove impurity in sesame;

(2) rinsing: rinsing soak time 1-2h, after soaking, sesame water content is 25-30%;

(3) seed is fried: 20min is fried in first big fire, and heave and change slow fire, fry the cold water of rear bold and vigorous stir-fry seed amount 3%, then fry 1min, frying temperature is not more than 200 DEG C;

(4) raise cigarette to blow off: sesame takes the dish out of the pot and raises flue dust, breeze and onal immediately;

(5) grind sauce: with stone mill, grinding-wheel grinder, sesame is worn into sauce, mill speed is advisable with 30rpm/min, destroys cell as much as possible;

(6) stir oil to slurry: sesame paste enters to stir oil cauldron, temperature is not less than 40 DEG C, point to add for 4 times be equivalent to sesame paste weight 80-100% boiling water; First time adds 60% of water total amount, and stir 40-50min, rotating speed 30rpm/min, whipping temp is not less than 70 DEG C; Second time adds 20% of total water consumption, and stir 40-50min, temperature is about 60 DEG C; Third time adds 15% of total water consumption, and stir 15min, temperature is about 50 DEG C, rotating speed 10rpm/min; Stirring 1h has a large amount of oil floats to go out; The formula of amount of water is: amount of water=(1-sesame paste oil length) x sesame paste amount x2;

(7) vibration point oil, an oil skimming: utilize succusion separation and Extraction of being tried one's best by oil to go out, pot body rotating speed 10rpm/min, second time oil skimming after pier oil 50min, then third time oil skimming after pier oil 50min; Dregs of linseeds or sesame seeds temperature is 40 DEG C.

After adopting above step, patent of the present invention compared with prior art, has the following advantages: required equipment is simple, operational safety, can obtain high-quality sesame oil, is of high nutritive value, can obtains sesame protein and the sesame peptide of low sex change high-quality simultaneously.Through checking and simultaneous test, under enzymolysis process condition of the present invention, percent of total oil can reach about 93.18%, under selecting preferred processing condition, percent of total oil can reach about 97.98%, improves 12 percentage points than the percent of total oil of enzymolysis after traditional damp and hot pre-treatment.
