Abstract
The invention relates to a method for extracting litchi fructose and belongs to the technical field of agricultural production. The production method includes the following steps that litchis are soaked in color protecting liquid after being peeled and are stirred, 3000-5000 U/g cellulose and 2000-4000 U/g pectinase are added after precipitation, enzymolysis is performed for 1-4 h at the temperature of 30-40 DEG C, extraction is performed for 5-12 h at the temperature of 50-80 DEG C through 1:3-1:5 water, and collected fructose is dried in vacuum for 5-10 h at the temperature of -20 EDG C to -30 DEG C and then is beaten into powder. The production method is easy to operate, litchi fructose is extracted to the maximum extent, the color protecting function is achieved, and nutritional ingredients in litchis are effectively reserved.
Description
Technical field
The present invention relates to a kind of method extracting lichee fructose, belong to field of agricultural production technologies.
Background technology
Lichee (formal name used at school: LitchichinensisSonn.) originates in SOUTHERN CHINA, is subtropical fruit tree, aiphyllium, height about 10 meters.Pericarp has fish-scale shape projection, scarlet, purplish red.Translucent congealed fat shape when pulp produces fresh, taste is fragrant beautiful, but not storage endurance.Lichee and banana, pineapple, longan are together known as " the large fruit in the southern part of the country four ".Lichee is well-known because of poplar highest-ranking imperial concubine eating, makes Du Mu write eternal well-known phrase of " rides human society cv. Feizixiao, and nobody knows it is lichee ".
The contained abundant sugared part of lichee has supplementing energy, the symptoms such as god is tired; Fructus Litchi is containing abundant vitamins C and protein; Lichee has the effect of subduing swelling and detoxicating, hemostasis and pain-relieving; Lichee has abundant VITAMIN, can promote the blood circulation of fine vascular, prevents the generation of freckle, makes skin more smooth.Litchi flavor is sweet, sour, warm in nature, enters the heart, spleen, Liver Channel; Pulp has tonifying spleen benefit liver, regulate the flow of vital energy enrich blood, effect of warming middle-JIAO to relieve pain, heart tonifying and tranquilizing; Core have regulate the flow of vital energy, dissipating bind, pain relieving effect; Can stop hiccup, only diarrhoea, be the dietotherapy good merchantable brand of intractable singultus and diarrhea before dawn person, have benefit brain and enhancing fitness simultaneously, whet the appetite beneficial spleen, has the effect promoting appetite.
Containing 6 carbon atoms in fructose, being also a kind of monose, is the isomers of glucose, and in the juice that it is present in fruit in a large number with unbound state and honey, fructose can also be combined with glucose and generate sucrose.Pure fructose is clear crystal, and fusing point is 103 ~ 105 DEG C, and it is crystallization not easily, is generally viscous liquid, soluble in water, ethanol and ether.Fructose is the sweetest monose.
Chinese patent, application number: the 201410129369.2 smart extracting method disclosing a kind of sweet potato starch, comprise the following steps: (1) is not cleaned Ipomoea batatas, are directly pulverized by Ipomoea batatas, obtain sweet potato paste; (2) by sweet potato paste dilute with water, the weight ratio of sweet potato paste and water is 1: 3 ~ 5; Then filter, obtain filtrate; (3) in filtrate, add the mixed solution of the lapping powder of plaster stone, Folium Ipomoea extract and soybean oil, the add-on of mixed solution is 0.1% of filtrate weight, then stirs; During preparation mixed solution, the weight proportion of the lapping powder of plaster stone, Folium Ipomoea extract and soybean oil is 10: 1: 1, first the lapping powder of plaster stone is put into water and be dissolved into saturated parget water, then add Folium Ipomoea extract and soybean oil, stir and obtain mixed solution.(4) after stirring, staticly settle, in filtrate, earth, sweet potato starch and water are just separated into upper, middle and lower-ranking, and (5) drain the water on upper strata, then take out sweet potato starch; (6) sweet potato starch dried or dry, dress bag.But the method extraction step is complicated, being only extract starch, is not extract fructose.Therefore develop a kind of method tool extracting lichee fructose to be of great significance.
Summary of the invention
The object of this invention is to provide a kind of simple to operate, protect to greatest extent and extract lichee fructose, there is colour-preserving function, effectively retain the extracting method of the nutritive ingredient of lichee.
In order to realize the object of foregoing invention, the technical solution adopted in the present invention is:
Extract a method for lichee fructose, comprise the following steps:
Be immersed in colour protecting liquid after lichee is removed the peel, stir, cellulase 3000-5000U/g is added after precipitation, polygalacturonase 2000-4000U/g, enzymolysis 1-4h at 30-40 DEG C, then uses the water of 1:3-1:5, at 50-80 DEG C, extract 5-12h, by the fructose collected at-20 DEG C--vacuum-drying 5-10h at 30 DEG C, beats powder.
Raw material lichee needs the lichee adopting Guangdong Huizhou Boluo to produce.
Colour protecting liquid adopts citric acid: sodium bicarbonate 1:1 is made into.
Litchi powder after powder is beaten in drying crosses 500 mesh sieves.
the present invention relative to the beneficial effect of prior art is:
The present invention is simple to operate, extracts lichee fructose to greatest extent, has colour-preserving function, effectively retains the nutritive ingredient of lichee.
