Abstract
The present invention relates to a preparation method for further processing tomato products. In the method, low-carbon polar organic solvents containing water are used for extracting tomato concentrate or tomato flavor substances in peel residue, and then, the low polar solvents are used for extracting out lycopene; finally, edible additives enriching diet tomato fiber are obtained. The method can be used for producing highly purified lycopene powder having high yield, the purity of the lycopene powder is larger than 50%, the highest purity can reach 95%, and the present invention can be conveniently applied to medicine and health products. Simultaneously, the tomato flavor substances enriching beta-carotene, xanthophyll and other kinds of carotenoid, other vitamins, organic acids, tomato lipid, flavone, sugar and the aromatic substances of tomatoes can be also produced, and the tomato flavor substances can be used as food additives for the nutrient enrichment or the seasoning of drink and food. In addition, the obtained residue can be directly used or processed as diet fiber in food industry or other industries.
Description
Technical field
The present invention relates to a kind of deep process technology of tomato product, especially to the extraction of tomato flavor thing and lycopene
Background technology
Be extensive use of tomato product in the grocery trade, existing at present several different methods is used for the tomato product of production different cultivars.Because have multiple nutritional components in the tomato, its process technology is the emphasis that people pay close attention to always.
Lycopene is a kind of of carotenoid, have many physiological functions, the discovered in recent years lycopene has the antioxygenic property stronger than other carotenoid, discover that in addition content of lycopene is crossed low relevant with some chronic disease and tumour in the human body, as: prostate cancer, the cancer of the uterus, artery sclerosis etc., also relevant with people's life-span simultaneously, therefore developing lycopene is the big problem that present people pay close attention to.
In the tomato except that being rich in lycopene, also be rich in class carrot vitamin and other vitamins such as beta carotene, lutein, contain organic acid, tomato lipid, oryzanol, flavonoids, sugar and tomato aromatic substance etc. simultaneously, higher nutritive value is arranged, can be used as the tomato flavor material and be used for beverage and food additives such as flavouring and beverage, cold drink, to strengthen nutrition and the mouthfeel or the performance of food.
At present, abroad openly the patent of tomato deep processing is more, for example, and EP0844831, CN1251745, US5858700, US5965183 etc.Need material through oven dry or freeze drying before in its disclosed method, extracting lycopene, extract with low polar solvent then, and higher in its resulting lycopene extract owing to resin object content, for the lycopene that obtains higher degree also needs complicated aftertreatment technology.In order to reduce the resin object of lycopene extract, a kind of sig water treatment process of using has earlier been proposed among the Chinese patent CN1298904.Obviously need special-purpose drying equipment in the method to many reported in literature, and fail tomato is more comprehensively fully utilized.
The existing tomato in China plantation and the processing place of production because special region, climatic factor makes that the content of lycopene of its tomato is higher, become the strongest raw material of lycopene processing mainly in western part.For this reason, the present invention proposes a kind of production method that fully utilizes the tomato product deep processing of tomato production high-purity lycopene powder, tomato flavor thing and dietary fiber after testing through years of researches.
Summary of the invention
The object of the invention is, a kind of tomato product deep-processing method is provided, this method at first utilizes moisture low-carbon (LC) polar organic solvent to extract tomato flavor thing in tomato concentrate or the skin slag, utilize low polar solvent to extract lycopene then, obtain being rich in the edible additive of tomato dietary fiber at last.Utilize this method high produced in yields to go out highly purified lycopene powder, its purity reaches as high as 95% greater than 50%, can be conveniently used in medicine, the health products.Also can produce the tomato flavor thing of carotenoid such as being rich in beta carotene, lutein and other vitamin, organic acid, tomato lipid, flavones, sugar and tomato aromatic substance simultaneously, can be used as fortification or seasoning that food additives are applied to the diet product.In addition also can be directly or after processing, be used for food or other industry as dietary fiber with the residue that obtains.
Tomato product deep-processing method of the present invention follows these steps to carry out:
The extraction of a, tomato flavor thing
At first utilize directly to mix with miscible organic low-carbon alcohols, the ketone solvent of water and carry out lixiviate with the wet tomato skin of tomato concentrate or pulverizing, wherein organic low-carbon alcohols is methyl alcohol or ethanol, ketone is acetone or butanone, solid-liquid ratio is 1: 1.5-1: 10, the moisture content that mixes the total material in back is controlled at 5%-40%, extraction temperature is 50 ℃-90 ℃, the lixiviate mode adopts single jar of extracted many times or the lixiviate of multiple tank adverse current, also can adopt continuous extraction equipment, obtain corresponding extract, through being evaporated near doing, the paste behind the decompression desolventizing is the tomato flavor thing; For the ease of the slag charge drying, can be with isolated slag charge with organic low-carbon alcohols, ketone solvent in normal temperature-85 ℃ direct drip washing solid slag, leacheate and extract merge, and are evaporated near doing, the paste behind the decompression desolventizing gets the tomato flavor thing; The tomato flavor thing can be directly used in the allotment of tomato drink or cold drink, then with remaining solid slag under 400-600Pa pressure, 50 ℃-85 ℃ of temperature heating decompression removes residual organic solvent, and can to obtain red recrement standby;
The extraction of b, lycopene
The recrement that obtains is added low polar organic solvent acetone or butanone or ether or propyl ether or ethyl acetate or benzinum or carrene, solid-liquid ratio is 1: 2-1: 8, extract in 50 ℃-85 ℃ heating, extracting mode adopts single jar of extracted many times or the lixiviate of multiple tank adverse current, direct crystallization was separated out crystal after isolated extract concentrated through reducing pressure, or in the crystallization feed liquid, add the absolute ethyl alcohol of 1-2 times of volume, promote the red crystallization of tomato to separate out, can obtain lycopene powder by washing, vacuum drying through isolated lycopene;
C, with remaining residue under 2000-5000Pa pressure, remove solvent under 60 ℃ of-85 ℃ of heating conditions of temperature, be white or faint yellow easy moisture absorption powder material through the recrement behind the desolventizing, this material is rich in tomato dietary fiber.
The tomato concentrate is the moisture tomato concentrate or the moisture tomato solid content of bright tomato after making beating, separation skin seed, centrifugal dehydration of finished product or semi-finished product catsup or tomato meal or the processing of other method; Tomato skin is the tomato skin after skin or seed separate.
