Abstract
The invention discloses a technology of extracting cottonseed oil by subcritical butane. The technology comprises the following steps: weighing a certain amount (200g) of cottonseed powder and filing in a charging barrel, then, placing in an extraction tank, and vacuumizing a container to the vacuum degree which is below 0.1MPa by a vacuum pump; injecting an extraction agent butane, and heating the extraction tank by circulating hot water and controlling the temperature; after a period of time of extraction, discharging liquid mixed oil (a subcritical liquid containing liposoluble components) from the extraction tank and entering into an evaporation tank for reduced-pressure vaporization, thereby obtaining the cottonseed oil through reduced-pressure vaporization; precisely weighing the weight, and calculating the extraction rate. The method provided by the invention has the advantages of mild reaction, less product pollution, low production cost and high yield, and the cottonseed oil is extracted under a condition of normal temperature or low temperature, so that the characteristics and nutritional components of the target product are prevented from being damaged.
Description
Technical field
Patent of the present invention belongs to Oleum Gossypii semen and extracts field, relates in particular to a kind of method of subcritical fluid extraction Oleum Gossypii semen.
Background technology
The cotton base of best buy a large amount of cottonseed of by-product in providing a large amount of high-quality cottons for country of China, the main application of cottonseed is to be processed into Oleum Gossypii semen and cotton cake dregs albumen.Foodstuffs industry " 12 " planning proposes, and puts forth effort to increase rapeseed oil, peanut oil, Oleum Gossypii semen, the sunflower seeds wet goods grease production taking domestic oil plant as raw material, improves oil plant mass-producing level of comprehensive utilization, and protein product is extracted in exploitation.This research is intended to explore novel method and the technique of extraction Oleum Gossypii semen, improves on the one hand Oleum Gossypii semen productive rate and quality, on the other hand for the extraction and application of cottonseed protein lays the first stone.
Oleum Gossypii semen mainly contains four kinds of lipid acid compositions, is respectively linolic acid (46.7～58.2%), palmitinic acid (21.4～26.4%), and oleic acid (14.7～21.7%) and stearic acid (approximately 2%), wherein approximately 75% is the unsaturated fatty acids useful to human body.Meanwhile, Oleum Gossypii semen is the functional ingredient such as rich in vitamin E, sterol and squalene also, is a kind of very outstanding natural edible oil.Oleum Gossypii semen, except directly eating, can also be made frying oil, shortening, oleomargarine, and can be processed into softening agent, ready mixed paint, also can be used as and produces the industrial raw material of stearic acid, Palmiticacid, glycerine, propanedioic acid and extract linoleic raw material etc.After Oleum Gossypii semen modification, can be used as high-grade leather fat, also can prepare biofuel, have good application prospect.
Subcritical fluid extraction technology (subcritical fluid extraction technology) is that fluid or its mixture of subcritical state is solvent, under room temperature and certain pressure, in system, in succession pass through the processes such as lixiviate, evaporation precipitation, compression, condensation recovery with solute, from agricultural-food (food), extract a kind of novel method of target component.It is a kind of new separation technology growing up after supercritical extraction technique.Subcritical technology solvent consumption is few, fluid coefficient is little, dissolvent residual is low, save solvent and later process, low-temperature extraction, equally with SCF-CO 2 can keep the original character of material, and extracting pressure is low simultaneously, be beneficial to large-scale industrialization and produce, can be widely used in the fields such as food, medicine, chemical industry, environmental protection.Subcritical abstraction method is applied to the extraction of Oleum Gossypii semen, can improves Oleum Gossypii semen quality, retain better raw material nutritive value and functional component.
Summary of the invention
The object of patent of the present invention is to provide a kind of method of subcritical butane extraction Oleum Gossypii semen, is intended to solve the steam that traditional squeezing or extraction cottonseed oil tech use many, and coal, electricity and the manpower consumption's of boiler is many, comparatively serious to the pollution of environment.
The present invention is achieved in that a kind of method of subcritical fluid extraction Oleum Gossypii semen, it is characterized in that comprising the following steps:
Step 1, get the raw materials ready:
By the cottonseed peeling of peeling off, pulverize and obtain Cotton Seed powder.
Step 2, charging:
By a certain amount of, the Cotton Seed powder making in step 1 is put into barrel, then this barrel that Cotton Seed powder is housed is put into extractor, with vacuum pump by the vacuum tightness of being pumped in extractor below 0.1MPa; Described barrel is the netted silk fabric of 200 object.
Step 3, extraction:
In extractor in step 2, be that 1g:6.5ml injects extraction agent butane by solid-liquid ratio, adopt circulating hot water to heat extractor, controlling extraction temperature is 40-50 DEG C, and extraction time is 30-40min, and the mixed solution after extraction is separated to evaporating pot.
To injecting in extractor and the extraction agent butane of equivalent last time, repeat said process again.
So repeat, after 3-4 time, barrel to be taken out from extractor, now the cottonseed meal protein content in barrel is about 62%.
Step 4, evaporation:
Mixed solution described in step 3 is carried out in evaporating pot to reduction vaporization, remove remaining extraction agent;
Temperature is controlled at approximately 50 DEG C, in the time that evaporating pot tensimeter arrives 0.1Mpa, stops, and now remaining extraction agent volatilization is complete, and the liquid obtaining is Oleum Gossypii semen.
The granularity of the pulverizing described in step 1 is 50-60 order.
Vacuum tightness in step 2 in extractor requires below 0.1MPa.
Inject the amount of extraction agent taking submergence material as good, in extraction process, requiring each extraction temperature is 40-50 DEG C, and extraction time 30-40min extracts 4 times repeatedly.
Beneficial effect:
The steam that has solved traditional squeezing or the use of extraction cottonseed oil tech is many, coal, electricity and the manpower consumption's of boiler is many, the problem comparatively serious to the pollution of environment, this subcritical abstraction technology is compared and can not only be reduced production costs with solvent extraction method with traditional milling process, increase yield, and be to extract under normal temperature or cold condition, can keep the characteristic of target product and nutritive ingredient to be without prejudice.In addition generally all low toxicity is harmless for extraction agent, has extracted rear extraction agent and has vaporized at normal temperatures and pressures, and solvent is easily separated and residual few, and compressible liquefaction cycle is used.The Oleum Gossypii semen quality better of subcritical fluid extraction, except acid number, moisture and volatile matter content index, the quality index that other all reach one-level squeezing finished product Oleum Gossypii semen national standard substantially, can reduce refining procedure, reduces refining cost.By product cottonseed meal protein content that subcritical abstraction obtains is high and sex change does not occur, and color and luster is pale yellow near white.The feed that can be used as high-quality also can further extract and obtain highly purified refining albumen, meets human protein's demand.
