Abstract
The present invention discloses a process for decoloring and refining almond oil, which comprises the following steps: heating raw almond oil; adding a decolouring agent into the heated raw almond oil; continuously stirring the raw almond oil at constant temperature; filtering the mixture after the steps of adsorption and purification to obtain decolored and purified almond oil. The almond oil decolored and refined by the process has the characteristics of nearly no color, clearness, transparency and no strange smell, keeps the original nutrient ingredients and aroma of almond oil, and meets the standard requirements of export products. The process has the advantages of safe operation, high efficiency, no color return after decoloring, simple operation and low cost. The present invention provides a new technology for developing refined almond oil products, provides a new method for decoloring almond oil, and enhances the grade of almond oil products. The high-quality almond oil prepared by the process of the present invention can be widely applied to functional foods, advanced cosmetics, medicines and other fields, and has favorable development value and important significance for earning foreign currency by export, promoting almond industry to develop and increasing the income of fruit growers.
Description
Technical field
The present invention relates to a kind of grease-decolor technology, particularly relate to a kind of almond oil decoloring refined process.
Background technology
Prunus amygdalus oil is a kind of xylophyta oil that has nutritive value and function, and almond grease average content is about about 55%, and wherein, unsaturated fatty acid content reaches more than 95%, oleic acid content 70.58%, and human body can not synthesize.And the linoleic acid plus linolenic acid content height of needed by human is respectively 24.75% and 0.12% in the Prunus amygdalus oil.Prunus amygdalus oil is first-class functional edible oil, eats Prunus amygdalus oil, can reduce the sickness rate of diseases such as hypertension, heart trouble and apoplexy; The Prunus amygdalus oil zero pour is very low, and oil still can keep clear liquid state in the time of-10 ℃, just condenses in the time of-20 ℃, can be used as deicing fluid, also is a kind of senior lubricant of precision instrument; Prunus amygdalus oil has zero pour low, not thickness, good dispersity, lubricated characteristic such as preserve moisture, and is the high quality raw material of making superior cosmetics and senior plastic solvent, also is the important source material of medicine and healthcare products.Prunus amygdalus oil all has wide application prospects in industries such as foodstuffs industry, medicine industry, makeup.Demand constantly increases in recent years, welcome by the domestic and international market.
At present, the Prunus amygdalus oil that China produces mostly is orange-yellow raw oil, and impurity is many, and color is dark, and clarity is poor, and price is low.Rough Prunus amygdalus oil market price is 2～2.5 ten thousand yuan/ton, and refining Prunus amygdalus oil is 20～300,000 yuan/ton, and senior exquisite Prunus amygdalus oil world market valency is up to 50～600,000 yuan/ton.Along with the development of benevolence with apricot, almond output will increase substantially, and Prunus amygdalus oil also will become the leading product of benevolence with the apricot comprehensive process, and therefore, improving the Prunus amygdalus oil quality product is the task of top priority.
The present invention can be refining Prunus amygdalus oil Products Development a kind of novel technique is provided, and promotes the Prunus amygdalus oil product specification, strengthens competitiveness in the international market, and foreign exchange earning increases benefit.Simultaneously, to promoting benevolence apricot industry development, increase the orchard worker and take in significant.
Summary of the invention
The purpose of this invention is to provide that a kind of impurity is few, of light color, transparency is high, the almond oil decoloring refined process of high efficiency.
The present invention is achieved in that a kind of almond oil decoloring refined process to achieve these goals, and it comprises following processing step: get rough Prunus amygdalus oil, heating, add discoloring agent, uninterruptedly stir under constant temperature, ultrafiltration behind adsorption and purification can obtain decolorizing and refining Prunus amygdalus oil.
Rough Prunus amygdalus oil in the described technology is to be raw material with Sweet Apricot seed or Semen Armeniacae Amarum, the Prunus amygdalus oil that adopts squeezing or solvent extration to obtain.
Discoloring agent in the described technology is cyclodextrin and gac, and the weight ratio of cyclodextrin and gac is 0.8-1.2: 4.
Discoloring agent addition in the described technology is the 4-6% of thick Prunus amygdalus oil weight.
Heating temperature is 70-80 ℃ in the described technology.
Stir in the described technology to uninterruptedly stirring clockwise, the time is 5-7 minute.
Technical process of the present invention is as follows:
Rough Prunus amygdalus oil → heat → add discoloring agent → whip attachment → ultrafiltration → decolorizing and refining Prunus amygdalus oil.
Advantageous effect of the present invention is as follows:
1. process implementing safety of the present invention, efficient.
2. approaching colourless through the Prunus amygdalus oil product colour of this technology decolouring of the present invention, clear, free from extraneous odour has kept Prunus amygdalus oil inherent nutrition and fragrance, reaches the exported product standard-required.
3. technology good decolorizing effect of the present invention is not returned look after the decolouring, simple to operate, cost is low.
4. for refining Prunus amygdalus oil Products Development provides a kind of novel technique, for almond oil decoloring provides novel method.
5. this process implementing can improve the Prunus amygdalus oil product specification, strengthens competitiveness in the international market, and foreign exchange earning, promotion benevolence are taken in significant and good economic benefit, social benefit with apricot industry development and increase orchard worker.
The high-quality Prunus amygdalus oil of explained hereafter of the present invention can be widely used in functional foodstuff, superior cosmetics, medicine and other fields, has good exploitation to be worth.
The decolorizing and refining Prunus amygdalus oil product standard of explained hereafter of the present invention is as follows:
State: clear, color has Prunus amygdalus oil inherent fragrance and flavour, free from extraneous odour near colourless.
