Description

A kind of method that natural food pigment is extracted from tomato
Technical field
The present invention relates to deep-processing technical field of agricultural products, and in particular to a kind of that natural food pigment is extracted from tomato Method.
Background technology
Lycopene（lycopene）It is a kind of oxygen-free carotenoid, is also known as ψ-carrotene, belongs to isoprene Class compound, belongs to natural pigment, is primarily present in the ripening fruits of plant of Solanaceae tomato.Lycopene removes free radical The effect of outclass other carotenoid and vitamin E, singlet-oxygen quenching rate constant is 100 times of vitamin E.Kind Lycopene can also eliminate oxyradical by the chemical reaction of the active oxygen with other forms, such as hydrogen peroxide, nitrite anions Oxyradicals are waited, and oxyradical can cause lipid peroxidation to form multi-products, these products and human senescence, cancer The diseases such as generation, autoimmunity disease and anaemia have relation.It can be each caused by immunity degradation with effectively preventing because of aging Kind disease.Just under study for action, the effect of lycopene has drawn attention the function of the pre- anti-cancer of carotenoids.
The preparation method of lycopene mainly has chemical synthesis, super-critical fluid extraction, organic solvent extraction etc. Method.The chemical synthesis process of lycopene is numerous, has Wittig reaction methods, Wittig-Horner according to its key reaction Reaction method, aldehyde-sulfone method, Heck olefinations method, Ramberg are into alkene method and McMurry olefination methods etc..Chemical synthesis color Element is cheap, and color sensation, tone are stronger, reacted by chemical raw material and obtain, although reaching food-grade, can more or less bring The possible chemicals for influencing, even damaging health.Super-critical fluid extraction be using supercritical fluid have concurrently gas and The special nature of the double attribute of liquid under elevated pressure conditions, makes supercritical fluid be contacted with material, and the ingredient in material dissolves in In supercritical fluid, then by being depressured, heating up the methods of, separated extract.Although the recovery rate of lycopene Height, but large and super-critical extraction equipment is at high price, is unfavorable for product cost reduction.Organic solvent extraction is that tomato product is done It after dry, is extracted using organic solvent, filtered filtration residue continues to be extracted with organic solvent, and filtrate portion is thick by being concentrated to give Product purify crude product using means are isolated and purified, and finally obtain the higher lycopene of purity, with it is of low cost, The advantages of simple and reliable process, is widely applied in the extraction process of lycopene.
Chinese invention patent application number 201410570234.X discloses a kind of method that lycopene is extracted from tomato, Fresh tomato is taken to wash quiet, smashed to pieces, with hydrochloric acid tune pH values to 3-5, add in the enzyme intermixture of the 0.4-0.6% of tomato weight, It is statically placed in 40-60 DEG C of hot water, enzymolysis 3-5h, after suction filtration, filter residue leaches 3h at room temperature with absolute ethyl alcohol, filters, chlorine Imitative extraction, extract liquor is concentrated under reduced pressure, dry red powder, that is, lycopene.Chinese invention patent application number 201510275002.6 disclose a kind of extracting method of lycopene, are set with tomato and extraction solution ethyl acetate by solid-liquid ratio It is set to 1：3.2~3.5 pairs of lycopenes extract, and then carry out separation and are concentrated to give lycopene product.Chinese invention is special Sharp application number 201610586627.9 discloses a kind of extracting method of lycopene, using tomato skin as raw material, extracted, mistake Filter concentrates, is dry that lycopene, extractant are in 6# solvent naphthas, n-hexane, acetone, ethyl acetate, supercritical carbon dioxide One kind.
In said program the extractant of lycopene mostly for chloroform, n-hexane, ethyl acetate, acetone and other organic solvent, It is most of relatively low there are recovery rate, it is inflammable and explosive, toxic, from non-renewable resources the shortcomings of.Such as human body often exposes Under n-hexane steam, play the role of damaging central nervous system and motor nerve cells.And food-safety problem is increasingly People is subject to pay close attention to pay attention to, the requirement of Determination of Residual Organic Solvents is more and more stringenter, using toxic extractant residue can undoubtedly draw Send out worry of the people to health problem.Therefore, research, which substitutes toxic extractant, becomes the important topic of lycopene extractive technique.
The content of the invention
Extractant for current lycopene is mostly chloroform, n-hexane, ethyl acetate, acetone and other organic solvent, greatly Majority is relatively low there are recovery rate, it is inflammable and explosive, toxic, from non-renewable resources the defects of, the present invention propose it is a kind of from kind The method that natural food pigment is extracted in eggplant, the extractant nontoxic to human body extracts, environmentally protective in actual mechanical process, The color and luster of licopin can also effectively be kept not to be damaged simultaneously, be conducive to improve the quality of licopin.
To solve the above problems, the present invention uses following technical scheme：
A kind of method that natural food pigment is extracted from tomato, using dimethyl carbonate as extractant, specific extracting mode It is as follows：
（1）Tomato is immersed in cleaning agent, after vibration washing, then is immersed in deionized water, cleaning agent is removed, after cleaning Pre-dried is carried out, obtains the clean tomato in surface；
（2）By the tomato that the surface is clean, by microwave drying treatment, the moisture inside tomato is removed, obtains dry kind Eggplant；
（3）The tomato of the drying is immersed in ethanol-water mixed solvent, and is broken the tomato of the drying using wall-breaking machine It is broken, it is heated to reflux tentatively extracting, obtains lycopene primary extraction liquid；
（4）The lycopene primary extraction liquid is poured into dimethyl carbonate, in 55-75 DEG C of thermal and hydric environment, by magnetic force Lycopene extraction solution is obtained after stirring and leaching 1-2h；
（5）The lycopene is extracted into solution at 80-85 DEG C after evaporative removal dimethyl carbonate, concentrate drying obtains tomato Red pigment.
Preferably, the cleaning agent is sodium carbonate liquor, in sodium bicarbonate solution, potassium bicarbonate solution, solution of potassium carbonate One kind.
Preferably, the vibration washing is cleans using high-frequency vibration, and vibration frequency control is in 200-540Hz, by 2-3 The secondary cleaning frequency, the time of the vibration washing is 40-160 minutes.
Preferably, the microwave frequency is 300 megahertzs -5000 megahertzs, and the time of microwave treatment is 10-30 minutes.
