Description

Organic pecan oil and production technique thereof

Technical field

The present invention relates to a kind of method of producing organic pecan oil, art: two, biological and new medical technology, (seven) modern agricultural technology, 4, agricultural-food intensive processing and modern accumulating: agriculture and forestry product and extraordinary enhance productivity are processed.

Background technology

Semen Caryae Cathayensis has another name called " hickory ", grows at weather superior, fertile soil, in the physical environment that vegetation is luxuriant, belonging to pure wild fruit, is that the anima nurture in collection mountain region forms, without the natural green food that any public hazards are polluted, be also sample one of the highest kind in numerous Chinese dry fruit.

Have the protein of 7.8%-9.6% in Semen Caryae Cathayensis pulp, aminoacids content is up to 25%, and wherein human body is necessary

Amino acid accounts for 7 kinds; Containing 22 kinds of mineral elements in Semen Caryae Cathayensis pulp, wherein to the calcium that human body plays an important role, magnesium, zinc and phosphorus, iron level is very abundant, has very high nutritive value, and has the strong kidney of moistening lung, reduces blood fat, effect of prevention worry.Long-term edible, also to cancer, there is certain preventive effect.

Pecan oil, oil taste delicate fragrance, like sesame oil, have moistening lung nourishing effects, the low iodine value of its acid number is high, oleic acid, the unsaturated fatty acidss such as linolic acid account between 88-96%, higher than world-renowned edible oil---Fructus oleae europaeae oil, and it is atomic more than saturated fatty acid and twenty carbon to be difficult to digestion fatty acid content, be be easy to digestion, the high-quality edible oil of coronary heart disease can be prevented.Chinese patent

CN1854274 provides a kind of aqua extracting method of pecan oil; Operating as follows, 1) Semen Caryae Cathayensis of getting decortication grinds with the carrying out that the weightmeasurement ratio of feed liquid is 1: 3-5, makes walnut kernel grind to 60-150 order, get rid of slurries; 2) the pH value of slurries is reconciled: the slurries hydrochloric acid of milled or citric acid are adjusted pH to 4.0-5.5; 3) pyrolysis catalytic: the slurries mixing up pH being put into temperature is pyrolysis catalytic reaction 1-5 hour in the water-bath of 50-60 DEG C; 4) centrifugation: be on the whizzer of 4000-6000 rev/min at centrifugal force by slurries completely reacted for pyrolysis catalytic, centrifugal 15-30 minute; The boiled oil layer sucking-off on Starch Level will be attached to after centrifugation, and obtain edible vegetable oil, be required pecan oil.Zhou Mingliang etc. are studied the ether extraction of Semen Caryae Cathayensis in " Chinese mechanical journal " the 38th volume the 3rd interim " extraction process of pecan oil and characteristic research thereof ".

Summary of the invention

The object of the present invention is to provide organic Semen Caryae Cathayensis oil producing method of a kind of easy, nutritive value and health care, rational technology.

Technical scheme of the present invention is achieved in that and comprises the steps:

A, to peel off with decorticator, obtain organic Semen Caryae Cathayensis;

B, airing is carried out to organic Semen Caryae Cathayensis, control water ratio 3%-5%;

C, the organic Semen Caryae Cathayensis hydropress dried is added extrusion crude oil;

Organic Semen Caryae Cathayensis is made cake and puts into hydropress, often squeeze and throw cake 20-25 block, every block is about 4-6kg, equably pressurized hydraulic low pressure, when making pressure be pressed onto 110-120MPa, low pressure is transferred to high pressure, and uniform pressurization is to during 280-300MPa, during squeezing, can not be too fast, in order to avoid cake slag oozes out;

Filter after D, crude oil precipitation 36 ~ 48h, obtain processed oil;

After crude oil precipitation 36 ~ 48h, oil is evenly crossed through flame filter press and filters impurity, obtain processed oil.

advantage of the present invention is:

Production technique of the present invention gets that the product colour of oil is shallow, the special odor that has Semen Caryae Cathayensis and remain nutritive ingredient; Oven dry in traditional technology, steaming are fried and decoloration process needs to add gac or atlapulgite, oven dry is got oil and is made the increase of benzopyrene content need to add charcoal absorption, steam fry get oil color more deeply need to add activated decoloration, although can remove unfavorable factor, complicated operation, interpolation chemical substance can remove the special odor of nutritive ingredient and Semen Caryae Cathayensis.

The invention provides organic pecan oil production method of a kind of easy, nutritive value and health care, rational technology, can produce for short run special oil and technical support is provided, be suitable for promoting in edible fat production technical field.

Embodiment

Organic pecan oil production technique:

A, to peel off with decorticator, obtain organic Semen Caryae Cathayensis;

B, airing is carried out to organic Semen Caryae Cathayensis, control water ratio 4%;

C, the organic Semen Caryae Cathayensis hydropress dried is added extrusion crude oil;

Organic Semen Caryae Cathayensis is made cake and puts into hydropress, often squeeze and throw cake 23 pieces, every block is about 5kg, equably pressurized hydraulic low pressure, when making pressure to 115MPa, low pressure is transferred to high pressure, and uniform pressurization is to during 285MPa, during squeezing, can not be too fast, in order to avoid cake slag oozes out;

Filter after D, crude oil precipitation 36h, obtain processed oil;

After crude oil is precipitated 36h, oil is evenly crossed through flame filter press and filters impurity, obtain processed oil.

The present invention can be used for special oil and produces, and is applicable to nutritive value and health care's edible fat production, accomplishes pollution-free, less energy-consumption.
