Abstract
The present invention discloses a natural lichee preserving agent and its application method. Lichee preserving agent of this invention composed of lquid extraction of ethanol of canna rhizome powder and garlic; the said two substrates are compounded and formed natural lichee preserving agent, application method is taking concentrated lquid extraction of ethanol of garlic 2 to 5 to compound with 100 to 150 canna rhizome powder, formed natural lichee preserving agent, using preserving 500 lichee; or marinating lichee into lquid extraction of ethanol of garlic some time, taking out airing, encasing non-woven fabric bag, putting on the non-woven fabric bag containing canna rhizome powder; the preserving agent is pure natural product, no-toxic, no pollution for environment, no effect flavor of lichee; the natural preserving agent of this present invention has extensive source, easy access, low costs, with industrialization prospects.
Description
Technical field
The present invention relates to a kind of natural lichee preserving agent and using method thereof.
Background technology
Lichee belongs to subtropical evergreen plant Sapindaceae, is to originate in the semi-tropical fruit in China south China, and lichee eats from plucking to, and blanking time is short more good more, and the time one is long, and taste just becomes, and is difficult to store; And the production time of lichee is short, and the time that can have fruit is not long.Therefore, the fresh-keeping people's attention that always is subjected to of lichee.
From existing litchi preserving technology, mainly contain physical method (CN02134343.8, CN02115089.3, CN96122329.4, CN99117122.5, CN00114391.3, CN00105153.9, CN02115349.3,03140317.4, CN200410046993.2, CN200510043649.2); Chemical preservative (CN200510043291.3, CN95117628.5, CN200510031694.6, CN97105377.4, CN93111631.7, CN98112444.5, CN 01108551.7, CN99110216.9, CN00133518.9, CN03140439.1, CN200410055506.9); Antistaling agent combines (CN00130815.7, CN02134958.4, CN200410012758.3, CN 200610084202.4) with physical method.Fresh-keeping time of physical method is the shortest, chemical preservative and physical method to combine the effect that can reach best.Chemical preservative is the important leverage that realizes lichee fresh-keeping.
Summary of the invention
The purpose of this invention is to provide a kind of natural lichee preserving agent and using method thereof.
Technical scheme of the present invention is as follows:
Natural lichee preserving agent of the present invention is made up of the ethanol extract of canna rhizome powder and garlic.
React in the test tube of band rubber stopper with sodium acid carbonate and watery hydrochloric acid, with the CO that generates
2Derive and feed in the water, make unsaturated carbonate solution.The garlic of peeling was soaked 8～10 days in 30 ℃ of unsaturated carbonate solution, in the acetum of same temperature, soaked 10～20 days again, after the deodorization garlic is smashed to pieces, with concentration is that 50% edible alcohol soaks and extracted 4 days, filter the back and use Rotary Evaporators, obtain the stoste of the ethanol extract of garlic 50 ℃ of following decompression distillation.
Take by weighing the concentrate of the ethanol extract of garlic, cooperate, obtain the natural fresh-keeping powder, in the nonwoven freshness protection package of packing into, with the fresh-keeping packed lichee of nonwoven, lichee is placed on above the fresh-keeping powder in addition, 4 ℃, preserve under the 60%RH with canna rhizome powder.
Take by weighing 2～5 parts of the concentrates of the ethanol extract of garlic, cooperate, make natural lichee preserving agent, be used for fresh-keeping 500 portions of lichee with 100～200 parts of canna rhizome powder.
Perhaps lichee is soaked certain hour in the concentrate of the ethanol extract of garlic, taking-up is dried, and the nonwoven freshness protection package of packing into is placed on the nonwoven freshness protection package that canna rhizome powder is housed, and 4 ℃, preserves under the 60%RH.
500 portions of lichee are soaked 7～10 fens clock times in the concentrate of the ethanol extract of garlic, taking-up is dried, the nonwoven freshness protection package of packing into, be placed on carry out on the nonwoven freshness protection package that 100～200 parts of canna rhizome powder are housed fresh-keeping.
The invention has the beneficial effects as follows:
The present invention is a crude antistaling agent, can reduce the harmful microbe growth effectively, strengthens its resistance, can reduce moisture loss better, keeps the freshness of lichee, prolongs storage period.
This antistaling agent is all-natural product, and is nontoxic, and environment is not polluted, and do not influence the lichee local flavor.The used crude antistaling agent wide material sources of the present invention obtain easily, and cost is low, has industrial prospect.
