Description
Technical field
The invention discloses the preparation method of a kind of long-acting slow-release antistaling agent for litchi, belong to food preservative synthesis field.
Background technology
Fructus Litchi contains the multiple nutrients material that needed by human body is wanted, but lichee fresh-keeping is a problem.According to statistics, Fructus Litchi is every
The loss that year causes because rotting accounts for more than the 20% of total output.Fructus Litchi is after harvesting in storage, and pericarp browning is
The most serious problem, it shortens the Fructus Litchi shelf life life-span, reduces its commodity value.
At present, Fructus Litchi main product country such as Madagascar, South Africa, Mauritius, Australia, Israel etc. is main in the world
Sulphuring method to be used carries out Fructus Litchi normal-temperature fresh-keeping, and the metering of sulphuring is every 1600kg fruit burning 1kg chemistry bright sulfur, after process
Peel decolouring bleaches, and under 22 DEG C of room temperatures, after 3～5 days, peel recovers to consistent pink, this color energy permanent retention, and not
Through the fruit then browning that sulphuring processes.After sulphuring, peel becomes more pliable and tougher, is not easily broken during operation, after sulphuring treatment, through dilute hydrochloric acid
The fruit soaked also can recover some at 22 DEG C after 24h red.But, owing to being easily generated residual after sulphuring process, aftertaste, right
Health is unfavorable, and can not effectively control to adopt infecting of rear fungus particularly penicillium, and causes a large amount of dehydration of fruit to be lost
The problem such as heavily, is the most used by restriction.
Preservation by low temperature preservative at home and abroad existing longer history and ripe experience, its principle is dependent on the work of low temperature
With, the breeding of suppression microorganism, and slow down the Repiration of fruit.Fructus Litchi cryopreservation freshness date is about 30 days, fruit appearance
Fresh, local flavor is normal, but after its outbound, shelf life is shorter than the fresh fruit without cold preservation at normal temperatures, thus finds a good sale in remote fortune and bring
Bigger difficulty.
Quick freezing process is a kind of ideal preservation method, and quick freezing process can keep the original fresh flavor of Fructus Litchi and product
Matter, under the freezing environment of-18 DEG C, within more than 1 year, without browning phenomenon, in 27～30 DEG C of natural courses of defrosting, 10 is little in preservation
Time endocarp scarlet constant, also without brown precipitation liquid produce, so Fructus Litchi use " freezing " way, can reach prevent brown
Fresh-keeping, Long-term Storage, the purpose of product season, pin year.But in refrigerating process, the tissue cellularity of fruit can be affected, Fructus Litchi
Colloid solution in cell membrane makes it change osmosis type and elasticity because of irreversible dehydration.Fructus Litchi loses consolidation after thawing,
Show mud extraction soft state, and Fructus Litchi cell tissue dries out in freezing process, due to the degeneration of cellular content after defrosting,
Moisture can not all be absorbed, and causes fruit to lose the local flavor of fresh succulence.
Summary of the invention
The technical problem that present invention mainly solves: occur during only using for tradition lichee fresh-keeping process, sulphuring
Or it is easily generated residual after using with chemical preservative, unfavorable to health, and after cryopreservation, Fructus Litchi outbound room temperature transported
Journey is accelerated rotten, and the problem that condition is deteriorated, it is provided that the preparation method of a kind of long-acting slow-release antistaling agent for litchi, the present invention is first
It is ground into end after first Folium Bambusae washing being dried, then mixes with Folium Bambusae end after garlic clove section, add ethanol and glacial acetic acid, seal
By fermentation liquid concentrated by rotary evaporation after fermentation, it is mixed with gel with sodium stearate after regulation pH, then gel is surpassed with diatomite powder
Sound microwave treatment mix homogeneously, pulverizes after cooling and solidifying, obtains long-acting slow-release antistaling agent for litchi.The present invention uses natural former
Material, uses rear nontoxic residue-free, does not interferes with Fructus Litchi mouthfeel, it is only necessary to put in water at normal temperatures, can send out with Fructus Litchi mixing
Wave fresh-keeping effect, it is simple to long-distance transport, saved energy consumption, can promote the use of.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
(1) take fresh Folium Bambusae 300～400g, after being washed with deionized 3～5 times, be placed in Fructus Ananadis comosi sieve, at ambient temperature
Naturally dry, proceeded in tissue pulverizer subsequently, grinding and sieving, collect 20～40 mesh Folium Bambusaes unqualified；
(2) weigh garlic clove 100～150g, after artificial de-epithelization, cut into 0.8～1.2mm thin slice, add fill 120～
In the sealed fermenting tank of 160mL deionized water, sequentially adding above-mentioned gained 20～40 mesh Folium Bambusae unqualified, 85～100mL is anhydrous
Ethanol, 45～50mL glacial acetic acid, after Glass rod stirring mixing 10～15min, sealing and fermenting 10～15 days；
(3) treat fermentation ends, filter, gained filtrate is proceeded in Rotary Evaporators, stops dense during concentrated by rotary evaporation to 50～60mL
Contracting, gained concentrated solution is proceeded in beaker, dropping concentration be 0.1～0.3mol/L sodium hydroxide solution, regulation pH to 7.2～
7.6, obtain fresh-keeping extraction stock solution；
(4) in the round-bottomed flask of band reflux condensing tube, being sequentially added into 8～12g sodium stearates, 35～45mL above-mentioned gained are fresh-keeping
Extract stock solution, then flask is placed in digital display tests the speed in constant temperature blender with magnetic force, be heated to backflow, with 560～620r/min
Rotating speed constant temperature stirring reaction 30～45min, discharging while hot, cool down rapidly process 40～60s with liquid nitrogen, obtain extracting solution gel, standby
With；
(5) weigh kieselguhr 400～500g, add in Universalpulverizer, grinding and sieving, collect 180～240 mesh diatomites in powder
End, is 250～270nm ultraviolet treatment with irradiation 3～5h with wavelength, obtains pretreatment diatomite powder；
(6) counting by weight, weigh 40～60 parts of step (4) standby extracting solution gels successively, 45～55 parts of above-mentioned gained are pre-
Process diatomite powder, add in the beaker filling 10～15 parts of dehydrated alcohol, subsequently beaker is placed in ultrasonic-microwave chemistry anti-
Answering in device, be 12～14kHz in supersonic frequency, under the conditions of microwave frequency is 400～500W, react 15～25min, removal is burnt
Cup, is placed in ice-water bath cooling and solidifying, subsequently by during material proceeds to mortar in beaker, pulverizes, obtains long-acting slow-release
Antistaling agent for litchi.
The concrete application process of the present invention: count by weight, weighs the Fructus Litchi of 200～300 parts of fresh harvestings successively, and 10
～15 parts of gained long-acting slow-release antistaling agent for litchi of the present invention, add the foam insulation box filling 300～500 parts of deionized water at normal temperature
In, subsequently foam insulation box is placed in after lucifuge ventilation deposits 45～50 days, opens couveuse, observe Fructus Litchi and keep cerise
Pool, the phenomenon such as do not occur brown stain mouldy, and fruit is solid, the freshest succulence.
The invention has the beneficial effects as follows:
(1) present invention provides a kind of new significantly more efficient method to the fresh-keeping of Fructus Litchi, and this promotes water to developing rural economy
Fruit plantation, the fruit exit ability improving China is significant；
(2) antistaling agent of the present invention is possible not only to effective Preservation of Litchi chinensis Fruits, and the fruit such as Arillus Longan Arillus Longan are also had long acting fresh-keeping effect,
Having wide market prospect, can be mass-produced use.
