Description
(1) technical field:
The present invention relates to a kind of method of extracting the fresh fruit effective extract, particularly a kind of normal temperature extracts the method for fresh fruit effective extract; The invention still further relates to the store method of fresh fruit raw material, particularly its normal temperature store method.
(2) background technology:
The extracting method of general fruit working substance has two kinds: a kind of is to extract after squeezing the juice with fresh fruit, this method can obtain the purer extract of taste, but because this kind method only can be extracted effective part in the fruit juice, active ingredient in the pomace is wasted fully, therefore its recovery rate is very low, and cost is higher; Another kind method is with the fresh fruit fragmentation, extract with solvent, with the dry fruit active ingredient that gets of extract, as application number is 03117430.2, name is called the Chinese patent application of " a kind of method of extracting Momordica-Glycosides from Momordica grosvenori ", disclose a kind of extracting method of Momordica-Glycosides, the technology that said method adopted is: fragmentation, and---lixiviate---separates---filtration---drying, obtains finished product then.Wherein lixiviate is to be to extract solvent to adopt high-temperature water to carry with water, and concrete steps are that the Momordica grosvenori after the fragmentation is added the boiling 1～5 hour under the high temperature of 40～100 degree of 2～4 times water, extract, after water is carried 1～2 time, merge the water extract and carry out subsequent technique.When adopting high-temperature water to carry, through the boiling of several hrs, pulp is rotted by boiling, and change has taken place fruity, and fruital constantly volatilizees in digestion process, and after to be extracted the finishing, fruital remains little; When high temperature extracts, also the astringent taste in the Momordica grosvenori together can be proposed, high temperature has also destroyed original effective components in the fresh fruit simultaneously, has changed the original mouthfeel of fruit, and every indexs such as therefore existing mouthfeel with the living Momordica-Glycosides that really extracts, smell, color and luster are all well below fresh fruit.And because the fresh fruit storage life is short, it is rotten to go rotten easily, therefore produces and is subjected to seasonal effect, can't carry out long-term scale production.Existing fresh fruit generally adopts freezer to preserve, but the freezer reserve capacity is limited and cost is higher, and its pot-life is also very short, only is three months, can't satisfy the needs that producer is in enormous quantities, scale continues production.How to obtain a kind of suitable fresh fruit raw material antistaling process and utilize fresh fruit to carry out the extraction process of fruit effective ingredient, be the difficult problem of puzzlement enterprise always.
(3) summary of the invention:
The present invention will disclose a kind of method of extracting the fresh fruit effective extract under the normal temperature state; The present invention also will disclose the fresh fruit raw material the normal temperature store method.
The method of extraction fresh fruit effective extract of the present invention is identical with existing method,---lixiviate---separates and---filters---concentrating---drying also to comprise following processing step: the fresh fruit fragmentation, obtain the extract finished product, in order in leaching process, both to have guaranteed to propose effective ingredient in the fresh fruit, few lixiviate of trying one's best again goes out flavor and other taste beastly of the bitterness in the fresh fruit, leach extraction method described in the present invention is to adopt to carry out lixiviate at normal temperatures, generally be between 0～40 degree, to carry out lixiviate, preferred 5～35 degree; Its technology is that the water-stop lixiviate in 24～48 hours that adds 1～5 times of fresh fruit weight in the fresh fruit after the fragmentation gets leaching liquor.If above-mentioned fresh fruit raw material preserved or in the leaching liquor thalline breeding is arranged when the lixiviate, then in leaching liquor, add anticorrosion or Fungicidal substance in order to prevent; Do not contain hazardous substance in the final extract and other additive in order to make, the present invention preferably selects for use edible alcohol to carry out sterilization treatment, generally is the edible alcohol that also adds 1～6 times of fresh fruit weight in the fresh fruit of fragmentation, and the concentration of described alcohol is 95%; Can earlier alcohol be added soak 10～20 minutes in the fresh fruit after, add entry again, also alcohol and water can be added simultaneously.With having added the above-mentioned fresh fruit material sealing of alcohol, place under the normal temperature state, can realize preserving.And in leaching process, in order to guarantee the quality of final extract, concentrated among the present invention is that temperature concentrates or normal temperature separates and concentrates in adopting, the temperature that middle temperature concentrates remains between 60～85 degree, last drying program also is to adopt low temperature drying, and its temperature remains between 30～70 degree.
This technology is specially adapted to the extraction of Momordica grosvenori working substance, also is fit to the extraction of other fresh fruit working substances such as longan, matrimony vine certainly.
The fresh fruit working substance extract that extracts with the method for the invention has following advantage: 1, because of this method remains on normal temperature and low temperature work down always, fresh fruit active ingredient can be not destroyed.2, because of fresh fruit is to ooze bubble under the normal temperature sealing state, fruital can not volatilize, and extract fruital flavor is the same with former fruit.3, because of fresh fruit oozes bubble under the normal temperature sealing state, temperature is low, influences the material of mouthfeel and astringent taste and oozes out seldom oozing under the bubble, and extract mouthfeel taste is not worse than former fruit.When 4, extracting the fresh fruit extract with normal temperature, the impurity in the fresh fruit does not infiltrate in the bubble liquid substantially under the bubble because of oozing in the normal temperature sealing, and extract finished product purity improves greatly, the finished product grade improves equally, therefore, need not to adopt technologies with high costs such as ultrafiltration, nanofiltration, cost reduces greatly.When 5, extracting the fresh fruit extract with normal temperature, bubble is oozed in the Yin Changwen sealing does not need heating, will reduce processing cost and environmental pollution.
Every indexs such as its mouthfeel of Momordica-Glycosides of extracting with the method for the invention, smell, color and luster are compared with the Momordica-Glycosides that proposes from fresh fruit with general technology, and quality has great raising.
