Abstract
The invention relates to blend oil containing peony seed oil and the preparation method thereof. The blend oil comprises 20 to 38 percent of the peony oil, 25 to 30 percent of corn germ oil, 25 to 30 percent of peanut oil, 3 to 5 percent of tea-seed oil, 4.5 to 7 percent of wheat germ oil, 0.5 to 2 percent of catechinic acid and 4 to 6 percent of a luffa extract; the preparation method of the blend oil comprises the preparation of peony seed oil, the mixing of the main raw material, the formation of an emulsification system and final formation of a clean and dirty-free blend oil product, wherein the peony seed oil is treated through the combination of sub-critical fluid extraction and molecular distillation technologies, the operating temperature is low, the heating time is short, grease oxidation and rancidity caused by high temperature are avoided, the separating degree and the product yield are higher, and the acid value of the peony seed oil can be lowered through molecular distillation; the blend oil is reasonable and healthy in matching up, the nutrition is balance, the blend oil with high stability and less oil-fume output can be formed, and the health of a cook person can be maintained for a long time.
Description
Technical field
The present invention relates to edible oil field, specifically a kind of ready-mixed oil containing peony seed oil and preparation method thereof.
Background technology
Existing edible blend oil nutrition is single, be difficult to meet human body and the demand supplemented the nutrients is balanced to alpha-linolenic acid and linoleic acid, and due to Chinese eating habit, custom to decoct, the mode cooking food such as fried and stir-fry, when cooking, be accustomed to again first by more than edible oil temperature rise to 200 DEG C, again food is put into oil to cook, during the process raising oil temperature and cooking food, oil smoke is produced because heating-up temperature reaches the smoke point of edible oil, if things go on like this, the oil smoke that edible oil produces, after being sucked by human body, considerable influence can be produced to health.
Peony seed oil is as a kind of novel material edible oil, containing micro-and fat-soluble, water soluble vitamins such as calcium, magnesium, potassium, be rich in unrighted acid (accounting for 92.69% of total oil mass), as leukotrienes, linoleic acid, eicosatrienoic acid, eicosenoic acid and gaidic acid etc., wherein linolenic content reaches 66.85%, secondly for linoleic acid is 23.34%.Peony seed oil extends and innovation as the one of edible oil, has outstanding green and the feature of health care, meets current consumption demand.The customary preparation methods of peony seed oil has milling process, organic solvent lixiviation process and supercritical carbon dioxide extraction method, milling process utilizes mechanical force that material embryo is squeezed and fuel-displaced, technique is simple, product vulnerable to pollution in production process, containing much impurity, microorganism and heavy metal easily exceed standard, and oil yield is low, and dregs of fat resid amount is high; In organic solvent lixiviation process, conventional organic solvent is n-hexane, benzinum and ether etc., and because solvent is inflammable and explosive, production security is poor, and product exists dissolvent residual, affects its quality and quality, also affects its application; , there is equipment de-sign manufacturing cost and the high problem of operating cost in overcritical titanium dioxide extraction, is mainly used in extracting high value-added product, is not suitable for process for producing bulk raw material in the industrial production.Also have after adopting extraction and with centrifuge, peony seeds crude oil is separated again, obtain final product oil, but centrifuge is comparatively strict to the requirement of hair well cuts, generally need the content setting impurity below 0.2%, general factory is difficult to reach this requirement, need to clean rotary drum while centrifugally operated, add solvent consumption, cause the increase of production cost.
Edible oil is in storage process, due to the effect such as illumination, oxidation, usually easily there is oxidative rancidity in edible oil, therefore need to add a certain amount of antioxidant to keep local flavor and the quality of edible oil in edible oil processing, there is certain toxicity, the unsafe factor such as pathogenic in chemical synthesis antioxidant, back to nature is the main trend in current food consumption market, the application of natural in food production causes the great attention of people, and the edible oil of existing interpolation natural, there is shelf-life shorter problem.
Summary of the invention
