Abstract
The invention relates to a method for purifying edible vegetable oil and belongs to the fields of food additives and preparation methods thereof. The method for extracting tomato seed oil comprises the following steps: grinding tomato seeds, packaging by using filter paper, putting the packaged filter paper cylinder into an extraction bottle for extracting, concentrating by using a rotary evaporator after the extraction is ended, thereby obtaining the tomato seed oil. The experiment proves that high-quality products can be produced by the method disclosed by the invention, and the content of unsaturated fatty acids contained in the prepared tomato seed oil is about 2 percent higher than that of the traditional solvent method.
Description
Technical field
The present invention relates to a kind of purification process of edible vegetable oil, belong to foodstuff additive and preparation method thereof field.
Background technology
Tomato is a kind of important vegetable crop in the world, within 2008, its output reaches 1.3 hundred million tons, wherein 1/3rd is used to suitability for industrialized production, produces a large amount of waste (3 ~ 5% in tomato deep-processing process, account for tomato fresh weight), wherein 60% is Tomato Seed.These wastes are mainly undersold by as elementary feed.Therefore how these wastes of efficiency utilization become tomato-sauce processing enterprise problem demanding prompt solution.
Grease containing 20% ~ 36.9% (dry weight) in Tomato Seed, also higher than soybean oleaginousness, wherein unsaturated fatty acids accounts for more than 70% of grease; In addition, being also rich in the bioactive ingredients such as tocopherol and plant sterol, is a kind of edible vegetable oil resource of high-quality.If these discarded Tomato Seed, as the raw material producing grease, will produce the health-care vegetable oil of the high-quality more than 140,000 tons.
China is third place in the world large tomato-sauce producing country and first tomato-sauce export State at present, within 2009, produce tomato-sauce more than 1,000,000 tons, owing to lacking corresponding by product deep process technology, current Tomato Seed be substantially used as feed and fertilizer, resource utilization and added value low.Be rich in unsaturated fatty acids in tomato seed oil, particularly linolic acid, the increment of tomato by product utilized mainly concentrate on tomato peel food fibre at present.
Existing be seen in document have milling process and extraction.All there is certain defect in these methods: the tomato seed oil complicated component that milling process obtains, and in cake slag, resid amount is high, and oil yield is lower, and energy consumption is larger; There is solvent recuperation and product with problem of solvent residual in solvent extraction method.
Summary of the invention
The present invention aims to provide a kind of extracting method that can improve the extraction yield of product and the tomato seed oil of quality.
The extracting method of tomato seed oil of the present invention, comprise and being pulverized by Tomato Seed, with filter paper packaging, packaged cellulose thimble is put into extracting bottle and is extracted, and extraction terminates rear rotatory evaporator and concentrates and obtain tomato seed oil.
Preferably, temperature during extraction is 35-50 DEG C.
Or the pressure preferably, during extraction is 8-20MPa.
Or preferably, the time of extraction is 180 minutes, and carbon dioxide flow is 24L/h.
More preferably, cellulose thimble is first placed 10 minutes before putting into extracting bottle at 60-100 DEG C.
Experiment proves, method of the present invention can produce high-quality product, and the obtained unsaturated fatty acids contained by tomato seed oil comparatively traditional solvent height nearly 2%.
