Abstract

The invention discloses a kind of production and processing method of low acid value high-quality edible oil tea-seed oil, including multi-stage separation supercritical CO2Extraction and molecular distillation refining.Multi-stage separation supercritical CO2Extraction camellia seed oil had both possessed higher recovery rate, and because the presence of multi-stage separation can separate moisture, free fatty, malodorous elements and pigment composition etc. simultaneously.Refining treatment is carried out by molecular distillation technique again, low acid value high-quality edible oil tea-seed oil is produced, for its oil yield up to more than 90%, acid value is less than 0.6, unsaturated fatty acid content more than 90%, rich in the natural anti-oxidation active component such as vitamin E, squalene, Sitosterolum.The production and processing method avoids " five is de- " technical process of traditional complexity, have the advantages that oil-collecting ratio is high, life cycle is short, avoid product from aoxidizing and become sour, keeps oily in nutritional ingredient, in the absence of inflammable and explosive dangerous, free from environmental pollution, solvent-free and heavy-metal residual, the natural quality of guarantee tea oil.

Description

A kind of production and processing method of low acid value high-quality edible oil tea-seed oil
Technical field
The present invention relates to edible oil preparing technical field, more particularly to a kind of life of low acid value high-quality edible oil tea-seed oil Produce processing method.
Background technology
Oil tea (Camellia oleifera Abel.) is the distinctive woody oil tree species in China, and camellia seed oil is with oil The oil that tea seed refines out, rich in multiple nutritional components such as unrighted acid, glyceride and various vitamins.Camellia seed oil is not only Good in color, smell and taste, because of its aliphatic acid composition, high-quality grease --- the composition of olive oil is closely similar with universally acknowledged, and it is not Saturated fatty acid content is higher than olive oil, and " smoke point " is high, is preferable high nutrition, low in calories, high-grade edible health-care oil.In recent years Camellia seed oil has been classified as the health type edible oil of emphasis popularization by international food and agricultural organization.The camellia seed oil quality of China is white through the U.S. Palace Institutes of Health Research and Chinese Center for Disease Control, which examine, to be confirmed, is superior to universally acknowledged olive oil, is described as " east olive Oil ".
The traditional oil plant fats and oils processing production in China is main to be squeezed using organic solvent leaching or high temperature, is then heated, is added The modes such as soda acid, adding assistant are decolourized, depickling, dehydration, dewaxing, degumming, technique and equipment extremely fall behind.On the one hand, grease Middle active skull cap components can largely lose in the preparation process of complexity, and fats and oils processing enterprise is integrally still in a height The situation of energy resource consumption.On the other hand, in oil production, a certain amount of waste liquid, waste gas is inevitably resulted from and is given up Slag.
It is presently disclosed on camellia seed oil production and processing method, such as《A kind of processing method of edible tea-seed oil》(application Number:CN201310042924.3)、《A kind of preparation method of edible oil tea-seed oil》(application number:CN201510954378.X)、 《A kind of high camellia seed oil production method of natural plant sterol content》(application number:CN201610442779.1)、《A kind of selenium-rich The processing method for refining tea oil》(application number:CN201610569049.8) there is preparation for processing complicated, the production time is longer The deficiencies of.For utilizing supercritical CO2It is less to extract camellia seed oil Patents, such as《A kind of supercritical CO2Abstraction purification oil tea The method of seed oil》(application number:CN201510646529.5), its production process lacks supercritical CO2The system of extraction process is ground Study carefully, the investigation of extraction process technological parameter is not complete, the change of each technological parameter in extraction process, can influence grease obtained product Matter, such as separation temperature, separating pressure, this patent supercritical CO2Extraction gained camellia seed oil contains moisture, it is necessary to enter to advance One step dewater treatment, the result is relevant with lacking other technological parameters, equally because its technological parameter lacked can cause patent without Method is implemented.Patent《The preparation method of camellia seed essential oil》(application number:201310070893.2) in equally employ supercritical CO2 Extraction and molecular distillation, but because of its supercritical CO2Extraction equipment and gained camellia seed essential oil is caused the problems such as preparation technology to prepare Technique is still relative complex, the step such as while dehydration is added, can not still avoid being deodorized, decolourize, and molecular distillation takes off Smelly process parameter investigation is not complete, and such as molecular distillation knifing rotating speed, molecular distillation condensation temperature, the process conditions can influence The working effect of molecular distillation and grease obtained quality, equally because the technological parameter that it lacks can cause patent not implement, And gained camellia seed essential oil quality is difficult to ensure that the standard for meeting edible oil.
The content of the invention
Extremely fall behind to solve technique in the prior art and equipment, preparation temperature is high, introduce organic solvent, oil product is received The deficiencies of rate is low, life cycle is long, energy consumption is big, the present invention provide a kind of multi-stage separation supercritical CO2Extract binding molecule distillation The method that refinery practice produces and processes low acid value high-quality edible oil tea-seed oil.
The purpose of the present invention will be achieved through the following technical solutions:A kind of production of low acid value high-quality edible oil tea-seed oil Processing method, the tea seed that will shell add multi-stage separation supercritical CO after crushing2In extraction equipment, extraction conditions is set, and The temperature and pressure of separating stills at different levels is adjusted, carries out camellia seed oil extraction, camellia seed oil crude oil is obtained in separating still I;By more fractions From supercritical CO2Extraction gained camellia seed oil crude oil, which is added in molecular distillation, carries out refining treatment, regulation vacuum, distillation temperature Degree, knifing rotating speed, charging rate and condensation temperature carry out refining treatment, and gained oil is low acid value high-quality edible oil tea seed Oil.
Preferably, the production and processing method of described a kind of low acid value high-quality edible oil tea-seed oil, the supercritical CO2 Extraction temperature is 40~50 DEG C, the supercritical CO2Extracting pressure is 30~45MPa, and extraction time is 1~2 hour.
Preferably, the production and processing method of described a kind of low acid value high-quality edible oil tea-seed oil, in the separating still The temperature of separating still I is 45~60 DEG C, and the pressure of separating still I is 10~20MPa.
Preferably, the production and processing method of described a kind of low acid value high-quality edible oil tea-seed oil, in the separating still The temperature of separating still II is 30~50 DEG C, and the pressure of separating still II is 4~8MPa.
Preferably, the production and processing method of described a kind of low acid value high-quality edible oil tea-seed oil, in the separating still The temperature of separating still III is 30~50 DEG C, and the pressure of separating still III is 4~8MPa.
