Description
Technical field
The invention belongs to natural extract technical field, and in particular to a kind of industrialized production side of lycopene oleoresin
Method.
Background technology
Lycopene is obtained from ripe tomato earliest, is one of stronger antioxidant.Its obvious health-care efficacy, resists
Oxidability is better than other carotenoid, is a kind of excellent natural.Lycopene has multiple biological activities,
It is the major carotenoids existed in human body.In recent years, lycopene was found have aobvious for preventing and improving prostatic disorders
Curative effect is write, is that health-product market is tried to be the first the gold product pursued at home and abroad.
The extracting method of current lycopene is a lot, but because raw material is in drying course, lycopene can be oxidized,
Loss is more, causes the lycopene rate of recovery not high.For example in Publication No. CN1364832A patents, with moisture 5~
The tomato meal of 10% (quality) is raw material, using the method for supercritical carbon dioxide extracting, and adds the mixing of ethanol and acetone
Solvent is to guide and support agent；Extracted in the state of being 5~30 kgs/hr in supercritical fluid carbon dioxide flow.Extracting yield is
80~90%.The method is relatively costly, the moisture obtained from drying, and lycopene is oxidized more.The method is dried
Operation chroma loss is big, and extraction yield is not high.In the patent of Publication No. CN102267855A, with tomato skin as raw material, warp
Solvent extraction, filtering, concentration, dry lycopene, wherein require that the tomato skin water content after dehydration is 6-10%, it is dried
Lycopene loss is more in journey, and its yield is difficult to ensure that production efficiency is also well imagined.And for example Publication No.
CN102516011A, with tomato as raw material, freeze-drying and dehydrating treatment, moisture requirement is less than 10%, and Extraction solvent is for acetone and just
Hexane, method is extracted for low-temperature ultrahigh-pressure cell instrument wall breaking technology secondary organic solvent.The lycopene that the method is prepared is brilliant
Body purity is higher, and because this method requirement moisture is relatively low, lycopene equally loses more.Therefore lycopene total yield
Relatively low, the another method need to use condition of ultralow temperature, and production cost is higher, is unsuitable for continuous mass production.
Learnt from current domestic literature, in Extracting of Lycopene, be required to the moisture of raw material less than 15%, or even
Require that moisture content of raw material is more low better in some patents, but when raw material dehydration is to less than 15%, lycopene content can be fast
Fast oxidational losses, chroma loss is up to 30%, causes overall recovery low, if raw material moisture is too high, conventional weak polar solvent recovery rate
It is low.Therefore, exploitation one kind can reduce lycopene and be lost in drying course, and from moisture raw tomatoes material higher
The method for extracting lycopene is extremely important, and drying course is tried one's best and reduces the loss of lycopene, improves production yield, reduces life
Produce cost, more conducively industrial continuous big production.
The content of the invention
In order to solve the difficult point of prior art, chroma loss of the lycopene in drying course is reduced, raising is extracted
Rate.The present invention provides a kind of method of industrialized production lycopene oleoresin.The method lycopene in drying course
Chroma loss is few, and lycopene extracts yield and overall recovery is higher.
The present invention solves the scheme taken of the technical problem：Comprise the following steps：
（1）Pretreatment of raw material：Tomato peel is dried by air flow dryer, Tomato Seed and skin are separated, and tomato skin is passed through
Fluidized bed drying, milling, obtains tomato meal；
（2）Extract:During tomato meal is added into alkanes and low molecule ketone mixed solvent, under water bath condition, stirring is carried
Take；
（3）Concentration：Extract solution is evaporated under reduced pressure concentration under vacuum, recycling design obtains final product lycopene oleoresin.
Step of the present invention（1）Middle air flow dryer, EAT is 200-400 DEG C, and leaving air temp is 60-90 DEG C,
Drying time is 10-60s, and tomato skin moisture is 35-45% after treatment.
Step of the present invention（1）Fluidized bed drying temperature is 40-50 DEG C, and the time is 40-100s.
Step of the present invention（1）Milling operation is whole to be blown using cold wind, obtains tomato meal moisture for 15-28%.
Step of the present invention（2）Alkane solvents are n-hexane, and low molecule ketones solvent is any in butanone, acetone
It is a kind of.
Step of the present invention（2）Ketones solvent volume parts are 15-24 parts, and alkane solvents volume parts are 85-76
Part.
Step of the present invention（2）Middle extraction bath temperature is 40-50 DEG C.
Step of the present invention（2）The ratio of tomato meal quality and solvent volume is 1 in abstraction process:3-7, the quality
Unit is kg, and the volume unit is L.
Step of the present invention（2）Extraction time is 2-4 times, and 2-4h is extracted every time, and each extract solution is merged.
Lycopene of the present invention and lycopene oleoresin colour value detection method normative reference《GB28316-2012 food
Safe national standard food additives tomato red》.
The computing formula of colour value extraction yield is in abstraction process of the present invention：
In formula：Y (%)-colour value extracts yield；The colour value of tomato meal after E1-drying；The color of E2-lycopene oleoresin
Valency；The quality of tomato meal, kg after M1-drying；The quality of M2-lycopene oleoresin, kg.
The computing formula of lycopene total recovery is in the present invention：
In formula：The total recovery of Y (%)-lycopene；The colour value of tomato peel before E0-drying；E2-lycopene oil tree
The colour value of fat；The quality of tomato peel, kg before M0-drying；The quality of M2-lycopene oleoresin, kg.
Using having the beneficial effect that above-mentioned technical proposal is produced：1st, raw material is ground using the method for high temperature flash baking treatment
Powder operation is blown using cold wind, reduces the oxidized speed of lycopene, and chroma loss is few, and the step colour value yield is more than 95%；
2nd, extracted using two kinds of larger double solvents of polarity spectrum.Polar solvent is using low molecule ketones solvent rather than low mass molecule alcohol
Class or esters, advantage are that ketones solvent dissolves each other effect more preferably with alkane solvents, and are not in molten using alcohols or esters
Agent mixes extraction wet stock layering with alkane solvents, causes to extract halfway phenomenon.The inventive method using n-hexane with
Low molecule ketones solvent compound collecting, can extract the small lycopene of polarity, and moisture material higher is adapted to again,
Yield more than 99% is extracted, lycopene overall recovery is up to 92%.No waste discharge, low cost, it is easy to accomplish continuous chemical industry
Industry is produced, remarkable in economical benefits.
