Description
Technical field
The present invention relates to the extractive technique of lycopene, specifically, is related to a kind of Hydrolysis kinetics of lycopene in black tomato
Method.
Background technology
Black tomato（Black tomato）Original South America, is the treasure of tomato family, because its fruit color and fruit be it is red
Black and gain the name, its fruit dietotherapeutic, research has shown that there is black tomato enriching yin to protect kidney, weight-reducing and pre- anti-cancer and heart
Effect of disease.Not only containing abundant anthocyanidin in black tomato, also containing substantial amounts of lycopene and antioxidant, in black tomato
Lycopene content is up to 28.0 μ g/g, is as many as 2 times of Lycopene in Tomatoes, and black tomato can be used as functional component tomato red
The potentiality raw material sources of element.
Lycopene can not synthesize in human body, can only be supplemented by food, therefore, the preparation method of lycopene,
The research of medicinal and health value and deep exploitation is received significant attention, and current lycopene is mainly from tomato, tomato skin, autumn olive
Extract in the natural products such as olive, watermelon, extracting method mainly has solvent extraction method, Microwave Extraction ripple, supercritical CO2Extraction
Deng.It is most widely used with organic solvent extraction, although this method process is simple, product quality is not ideal, there is pigment
The shortcomings of poor dissolution, color and luster are changed greatly, and extraction process use substantial amounts of organic solvent, be easily caused dissolvent residual in product,
Production cost is higher.Microwave abstracting completes at short notice the extraction of several samples component, and solvent load is few, but microwave abstracting kind
During Lycopene, still with organic solvent, also remaining organic solvent in product.Supercritical CO2Fluid can effectively by liposoluble substance
Extract from mixture, it is strong with dissolving power, mass transfer rate is fast, clean environment firendly the advantages of, using supercritical CO2Extraction

DEG C, 35 DEG C of resolution temperature, in the case of extracting 2h as entrainer with the n-hexane of inventory 20%, the recovery rate of lycopene can
Up to 93.98%.Wang Xianqing etc. is reported《Supercritical CO2Extract the technical study of lycopene》, in 30MPa, 60 DEG C, under the conditions of 2h,
Entrainer is made with absolute ethyl alcohol, the extract of the lycopene that 47.986g purity is 0.803% can be obtained in 100g tomato meals,
The amount of lycopene can reach 38.551mg or so.CN 1364832A are disclosed《One kind extract and separate tomato red from tomato
The method of element》, slurry is broken into using by tomato, then tomato data is dried in combination with vacuum drying through nitrogen protection
Method process, is finally ground into tomato meal, and tomato meal is carried out into supercritical CO2Extraction, extraction temperature：40～80 DEG C, pressure 15
～50MPa, CO2 flow is 5～30kg/h, and 3～8h of extraction time, the temperature of primary separator is 35～80 DEG C, pressure is 5～
15MPa, the temperature of second-stage separator is 5～50 DEG C, and pressure is 3～8MPa.Entrainer is the mixed solvent of ethanol and acetone, this
, using ethanol and acetone solvent, acetone is volatile and security is not good, and extraction time is long, 3～8h for patent.Publication number CN
1799674A is disclosed《The supercritical carbon dioxide method for extracting of lycopene in dry powder of tomato peel》, extracting pressure be 28～
50MPa, 45～70 DEG C of extraction temperature, extraction time is 1.5～5 hours, carbon dioxide usage amount：20～60 times, extraction aid is second
Alcohol, the patent tomato is size-reduced, and spray drying, lycopene is thermo-labile, is not suitable for spray drying.
The document reported and patent report the extraction using supercritical technology to the lycopene in tomato or watermelon,
The supercritical CO of the lycopene in not having document or patent report black tomato2Extraction.And report supercritical CO2Extraction tomato
Red pigment technique, some employings are volatile, the not high organic solution of security, and some operating pressures are high, and some extraction times are long, have
Raw material pre-treatment it is loaded down with trivial details.Therefore above-mentioned supercritical CO2Abstraction technique is not suitable for the extraction of lycopene in black tomato, this patent
Invent a kind of pretreatment of black tomato fruit, supercritical CO2Extraction, silica gel column chromatography, the method for obtaining lycopene crystal is black
Hydrolysis kinetics lycopene provides a kind of operable, industrialized Hydrolysis kinetics method in tomato.
