Abstract
The invention provides a preparation method of blended edible oil of peony seed oil and walnut oil. The preparation method comprises the following steps: grinding, carrying out supercritical extraction, carrying out molecular distillation, mixing, heating and stirring. The preparation method has a low operation temperature and short heated time; oxidization and rancidity of grease, caused by high temperature, can be avoided; the separation degree and the yield of products are relatively high; the molecular distillation also can lower an acid value of grease; efficient extraction and separation are realized and no impurities are generated; the aim that the purity of an extracted product is high is realized; and an operation process is simple, the extraction time is short, the cost is reduced and the production efficiency is improved.
Description
Technical field
The present invention relates to edible oil field, specifically the preparation method of a kind of peony seed oil and walnut oil blending edible oil.
Background technology
Peony seed oil is also containing abundant polyunsaturated fatty acid, and its nutritive value is considerably beyond being called as " oil of human health " olive oil, and linolenic acid content is more than 200 times of olive oil.Many index is also all planted higher than other oil.Again not easily oxide deposition at positions such as human vas wall, heart coronary arteries.These compositions make it in medical science and nutrition, play important function and become desirable edible oil just.Say without exaggeration that, the nutrition and health care effect of peony seed oil is that other edible oil is incomparable.The peony seeds deep processing product of listing are little, this greatly reduces the economic worth of China's peony seeds.
A kind of kiwifruit nut oil and extracting method thereof disclosed in Chinese patent Authorization Notice No. CN1483795, adopt CO_2 supercritical technology, obtained essential oil of low quality, and complex process, extraction time is long, and production cost is high, and yield is low.
In view of the foregoing, the preparation method of a kind of peony seed oil and walnut oil blending edible oil is now developed.
Summary of the invention
The object of the invention is, in order to overcome deficiency of the prior art, to provide the preparation method of a kind of peony seed oil and walnut oil blending edible oil, the ready-mixed oil prepared by the method has nutrition, the health care of peony seed oil and walnut seed concurrently; Effectively can prevent the generation of senile dementia simultaneously.
The present invention to achieve these goals, adopts following technical scheme: the preparation method of a kind of peony seed oil and walnut oil blending edible oil:
Step 1: get drying, unmetamorphosed peony seeds, pulverized after shelling, form the tree peony benevolence powder that particle diameter is 10-30 object, tree peony benevolence powder is put in extraction kettle, start extraction, extraction temperature is 35-55 DEG C, extracting pressure is 25-28Mpa, extraction time 120-150min, close extractor, inspection guarantees that sealing is tight, use high-pressure pump that the liquid CO 2 in hold-up tank is pumped into vaporizer, gasification is input in extractor after critical fluids state, peony seeds particle is extracted, the fluid-mixing of the CO2 after extraction and peony seeds essential oil inputs separator and carries out decompression separation, separation temperature is 30-55 DEG C, separating pressure is 0.2-0.4Mpa, disengaging time is 120-150min, CO2 after separation through liquefier liquefaction directly the defeated time hold-up tank of 20-30 DEG C recycle for next round extract and separate, each takes turns extract and separate time 2-8 hour, obtained elementary peony seeds crude oil after being separated, for subsequent use,
Step 2: the elementary peony seeds crude oil that step 1 is obtained joins in molecular still, vacuum in setting molecular still is 1.0-2.0Pa, temperature is 60-80 DEG C, rotating brush film rotating speed in molecular still is 120r/min, until elementary peony seeds crude oil is collected by heavy phase collecting tank and light phase collecting tank completely, collect in heavy phase collecting tank and obtain peony seeds crude oil, for subsequent use;
Step 3: the peony seeds crude oil that step 2 is obtained joins in molecular still again, the vacuum reset in molecular still is 1.0-2.0Pa, temperature is 60-80 DEG C, rotating brush film rotating speed in molecular still is 120r/min, until peony seeds crude oil is collected by heavy phase collecting tank and light phase collecting tank completely, collect in heavy phase collecting tank and obtain peony seed oil;
Step 4: get the walnut oil that quality accounts for peony seed oil gross mass 10%-50%, all joins in the thermostatic tank of 30 DEG C with peony seed oil, mixing and stirring, and obtained miscella is for subsequent use;
Step 5: container put into by the miscella that step 4 is obtained, and is heated to 100-120 DEG C, and heat while stirring, stir speed (S.S.) is 1000rpa, till clarification is without muddiness, obtains ready-mixed oil finished product.
The invention has the beneficial effects as follows: walnut oil fresh pure, nutritious, mouthfeel is light, aliphatic acid configuration is similar to breast milk, easy digested absorption, is the child development phase, the high-class healthy edible oil of women's gestational period and postpartum recovery.The nutrient content of this product: unsaturated fatty acid content >=92%, linoleic acid Ω-6 >=56%, leukotrienes Ω-3 >=14%, be rich in the nutriments such as natural VA, VD.Acidity≤0.5, the light free from extraneous odour of mouthfeel, pure raw original flavor, is particularly suitable for the tender and lovely stomach of baby.Walnut oil has brain tonic to support the effect of brain simultaneously: not containing cholesterol in walnut oil, effectively can prevent the generation of senile dementia; Abundant linoleic acid plus linolenic acid can get rid of the metabolic impurity of Ink vessel transfusing, makes blood purification, for brain provides new blood.
The present invention is directed to the problem that the potential safety hazard of interpolation chemical antioxidants existence mostly in traditional edible fat production is short with the shelf-life of adding natural, the present invention is by mixing walnut oil with peony seed oil, can be dispersed in grease by microemulsion system uniformly, microemulsion system have blocked the stability that Oxidation of Fat and Oils improves ready-mixed oil to a certain extent.
The preparation method of peony seed oil in the present invention, adopt the method that supercritical extract and molecular clock be combined with each other, not only operating temperature is low, heated time is short, the oxidation of the grease that high temperature can be avoided to cause with become sour, and the yield of separation degree and product is higher, and molecular clock can also reduce the acid value of peony seed oil and walnut oil blending edible oil, do not need to carry out centrifugally operated, reduce cost.
