Description

Produce the method for fresh grosvenor momordica concentrated solution

The present invention relates to a kind of technology of producing fruit juice, it is applicable to producing of various fresh fruit inspissated juices, is specially adapted to producing of fresh grosvenor momordica concentrated solution, and products obtained therefrom is widely used in food, beverage.

More high and cold mountain area, hilly country, northwest, Guangxi China Zhuang autonomous region osmanthus is born in the Momordica grosvenori open country.It is that Curcurbitaceae is perennial, climbs up by holding on to herbaceous species, dioecious a kind of wild plant fruit.It contains strong sweet substance, biology enzyme, lactone compound of vitamin, the protein of a large amount, non-sugared body etc.According to assay, contain 319～510 milligrams of vitamin cs in per 100 gram fresh fructus momordicae juice, be 1.2～3.2 times of Kiwi berry, being 10～17 times of citrus, is 20～32 times of banana, is 63～102 times of apple, be 79～127 times of grape, its sugariness is 300 times of sucrose, and it not only has higher edibility, also has higher medicine effect.Have removing heat from the lung to relieve cough, eliminate the phlegm and quench one's thirst, the invigorating the spleen relieving summer-heat, enriching blood and promoting secretion of body fluid suppresses asthma, and function such as bring high blood pressure down.Especially very useful to the diabetic that can not eat sugar, and have antitumaous effect.But, up to now, be to boil water after the life fruit is dried both at home and abroad as sweet tea-drinking usefulness always.It has not only destroyed effective nutrition of fruit, and is a kind of waste.It is reported, now generally adopt milling process to produce various fruit drinks.This method, not only the fruit juice yield is low, and what effective ingredient was carried lacks, and has destroyed vitamin, various nutritions such as protein.

The objective of the invention is, be fully utilized, protect its nutrition not to be destroyed, keep the color, sweet etc. constant of its Normal juice, improve the fruit juice yield, and a kind of method of producing fresh grosvenor momordica concentrated solution is provided in order to make precious Momordica grosvenori.

The present invention realizes that the technical solution of above-mentioned purpose is; for protect the triterpene that contains in the Momordica grosvenori, protein, starch, vitamin, chlorophyll, leaf aldehyde, leaf alcohol, steroid, saponin, higher fatty acids etc. effectively nutrition in producing the fruit juice process, do not go to pot; keep the color, sweet etc. constant of siraitia grosvenorii original juice, we have adopted biochemical method.Carry out the saccharification isomery after soon the ripe Momordica grosvenori through cleaning up will carry out fragmentation, allotment, slurrying, reform, and then its pulp is filtered, concentrates or concentrate back packing, sterilization.In order to keep the Normal juice local flavor, must protect the molecular structure of terpenes and steroid.Since terpenes, steroid be not with alkali institute can hydrolysis macromolecule compound, therefore, in producing the Normal juice technical process, taked the alkaline way of control.In order to promote the catalytic capability of various enzymes, reduce saccharification, esterification activation energy, make amylase, cellulase, cellulolytic enzyme, the catalysis of fat enzyme activation, transform and generate more barley-sugar, ketose to improve sugariness, prevents to go bad.In order to destroy pectin, favourable clarification filtration.In order to protect saponin, increase the lubricious sense of Normal juice.Must the strict stable p H value of controlling each stage in the technical process.In order to impel tryptic effect, destroy the peptide bond in the protein structure, to increase the amino acid in the fruit juice, improve Normal juice nutrition, in allocation process, taked to improve the way of pH value.By saccharification isomery and reformation, the water-insoluble higher fatty acids with contained in the fruit stone changes into the solubility ester, to improve homogeneity.Chlorophyll is converted into lutein, to increase the nature color sensation.And utilize esterification enzyme in the fruit juice, and the alcohol in the Normal juice, aldehyde are converted into ester, to eliminate different assorted flavor, increase nature perfume (or spice).In addition, unlikely destroyed for the structure of matter of protecting vitamins, in saccharification isomery, reforming reaction process, adopt the normal temperature enzyme reaction.In concentration process, should adopt decompression low temperature to concentrate.Device therefor, container should adopt by being advisable that corrosion-resistant material is made, as Stainless Steel, enamel, pottery, glass etc.

The concrete grammar of producing fresh grosvenor momordica concentrated solution is: with the pH value is 11～12 sterilization cleaning solution, behind the blue or green hair flush away with the fresh fructus momordicae epidermis, with deionized water or clear water flushing, gets final product when the pH value of deionized water after the flushing or clear water is 7 again.Then the Momordica grosvenori through cleaning up is broken into fragment.Momordica grosvenori after the fragmentation and blender, water are allocated by 1: 1: 1.5～2 weight ratio.Blender can use the carbonate of agar, starch and magnesium, calcium, iron to form.Its best percentage composition is agar 5%, magnesium carbonate 0.1%, calcium carbonate 0.25%, ferric carbonate 0.03%, starch 94.62%.In allocation process, should keep pH value=8.After the allotment it is sent in the beater and pull an oar.After the making beating it is sent into colloid mill, grind to form emulsion.In order to prevent protein denaturation, should control the interior temperature of charge of colloid mill at 20～40 ℃.Its variation of temperature can be controlled by the revolution of colloid mill.After the grinding emulsion is carried out the saccharification isomerization reaction, its reaction temperature preferably is controlled at 35～40 ℃, and optimal reaction temperature is 38 ℃.Through after the assay was approved, stop heating and leave standstill, treat liquid-solid separation after, liquid phase is put into the reformation groove, solid phase returned in the surge-tank recycled.The pH value that will be contained in the liquid in the reformation groove with blender transfers to 5 from 8 then, after mixing up with its filtration.And the gained filtrate low temperature that reduces pressure concentrated.Stop heating after waiting to be concentrated to a certain degree, lower the temperature by the nature cooling or with cooling water then, the cooling back is taken out and is carried out packing.Sterilize after the sealing, ultraviolet disinfection or Bath sterilization are preferably adopted in sterilization.The steam of discharging in concentration process can be used as the water purification utilization after condenser reclaims.Waste residue then can carry out the fermentation of multienzyme function, produces Momordica grosvenori soy sauce or oven dry and makes high sugar feed.

The present invention is owing to having adopted biochemical method and decompression low temperature concentration technique to produce fresh grosvenor momordica concentrated solution; not only protected the Momordica grosvenori rich nutrient contents effectively; the color of siraitia grosvenorii original juice, sweet original local flavor have been protected; and it is reasonable to have technology; easy to implement; fruit juice yield height, advantages such as good economical benefit.

Most preferred embodiment of the present invention:

The ripe fresh arhat fruit that does not have mould and damaged mashed scar with the soda lye wash of pH=11.Behind the blue or green hair of its epidermis flush away, use the deionized water rinsing after 731 cation exchange resin columns are handled again, when being 7, the pH value of the deionized water after the flushing gets final product.Take by weighing 100 kilograms of Momordica grosvenoris after washing, and it is dropped in disintegrating machine, be broken into≤fragment of 5～10mm.Fragment is poured in the stainless steel surge-tank then, to slowly pour in the surge-tank by blender and 200 kg of water that 5% agar, 0.1% magnesium carbonate, 0.25% calcium carbonate, 0.03% ferric carbonate, 94.62% starch are formed again, stir simultaneously, when the pH value is 8, stop allotment.After the allotment it is sent in the centrifugal beater and pull an oar.Send into the emulsion that grinds to form 20u in the colloid mill after the making beating again, and the emulsion temperature in the colloid mill is controlled at 35 ℃.After the grinding emulsion packed in the stainless steel saccharification isomery jar that has chuck,, make it carry out the saccharification isomerization reaction with being steam heated to 38 ℃ of constant temperature 24 hours.Test with the GB-food sanitary testing method,, stop heating and leave standstill through after the assay was approved, treat liquid-solid separation after, liquid phase is put into the reformation groove, solid phase returned in the surge-tank recycled.The pH value that will be contained in the liquid in the reformation groove with above-mentioned blender transfers to 5 from 8, mixes up the back and carries out vacuum filtration with sz-2 type vavuum pump, will have by filtrate being evacuated to of nylon filter cloth in the stainless-steel vacuum concentration kettle of chuck, heats with steam.When the gauge pressure of vacuum meter reached 650mmHg, heating-up temperature should be controlled at 75 ℃, the weight of solution to be concentrated be during the fruit of dropping into 2 times of weight, stop heating, and destroy vacuum, allow it cool off naturally, reduce to 20 ℃ of taking-ups and bottle.Sterilize with 40 watts of ultraviolet lamps in the sealing back, through selling after the assay was approved.The steam of in concentration process, discharging after condenser reclaims as the water purification utilization.
