Abstract

The present invention discloses a fresh flower freshness-keeping agent belonging to plant freshness-keeping field, each liter of the fresh flower freshness-keeping agent comprises the following raw materials by weight: 0.4-1g of gluconate, 15-30g of sucrose, 0.3-1. 5g of olive leaf extract, 0.2-0.8g of a humectant, 0.1-0.5g of a preservative and balance of water. The fresh flower freshness-keeping agent is a new bio-freshness-keeping agent and non-toxic fresh flower freshness-keeping product in the form of gluconate, which can be more easily absorbed by fresh flowers; and the freshness-keeping agent can more effectively supplement the trace elements to the fresh flowers, and is free of damage to the fresh flowers, low in cost, readily-available in raw materials, convenient to prepare, and easy to use.

Description

A kind of fresh-preservative

Technical field

The invention belongs to the preservation field of plant, particularly to a kind of fresh-preservative。

Background technology

Flower is a kind of timeliness and seasonality is very strong and growth conditions has certain requirements plant, the wilderness demand of flower, it it is the symbol of social progress and human civilization, in recent years, along with the raising of living standards of the people, Chinese flower production and consumption there occurs great change, flower industry is due to huge economic benefit and potential domestic and international market simultaneously, it has also become one of industry of current most development prospect, is described as " Gold Industry " of 21 century。

But, only drawback is that flower is not normally opened, good times don't last long can not virtue face stay forever at, flower, still provides for vital movement, preserve and view and admire restricted lifetime after adopting due to flower。

The Aging Mechanism of flower is: (1) microorganism is polluted and caused moisture disequilibrium。Flower is the part that plant is very delicate, will wilt if can not get sufficient moisture。Only when its cell keeps certain turgescence so that it is keep certain tensity, normal metabolic activity could be maintained, and keep the intrinsic form of flower, only could obtain when absorption speed is more than transpiration rate。If the conduit portion of xylem is blocked, make water suction reduce, cause flower senescence wilting, the main cause of dehydration has: the breeding of (a) microorganism encloses conduit, thus causing catheter blockage, impact flower absorbs moisture, and produces ethylene and other noxious substances and accelerate to spend aging。B () microbial metabolic products is absorbed by spray and encloses xylem vessel, the interference absorption to water, causes that flower dehydration is adjusted and withers；

(2) lacking energy substance, another main cause of flower senescence is that flower lacks the necessary energy sugar of vital movement, so that affecting homergy and making flower wilting；

(3) ethylene promotes flower senescence, and ethylene is a kind of endogenous hormones that plant self produces, it is possible to is produced by old and feeble and injured plant tissue, is the important internal cause of flower senescence。

Have certain preservation at existing fresh-preservative, but these fresh-preservatives have certain toxicity containing silver nitrate or Argylene etc., damage plant itself, in the market less than for flower fresh-keeping medicine。

Summary of the invention

It is an object of the invention to: for above-mentioned Problems existing, the invention provides a kind of fresh-preservative, adopt biological components as antistaling agent composition, the pollution nontoxic, minimizing is to environment, simultaneously work as fresh-keeping effect。

The technical scheme is that a kind of fresh-preservative, every liter is made up of by weight ratio following raw material: gluconate 0.4 1g, sucrose 15 30g, Olive leaf P.E 0.3 1.5g, wetting agent 0.2 0.8g, preservative 0.1 0.5g, surplus are water。

Preferably, every liter is made up of by weight ratio following raw material: gluconate 0.5g, sucrose 20g, Olive leaf P.E 1g, wetting agent 0.4g, preservative 0.2g, surplus are water。

Described Olive leaf P.E is to obtain via following preparation process: dry Folium olive, pulverizes, and the water adding 5～10 times of weight of Folium olive carries out microwave extraction, and extraction time is 1～4h；Centrifugal filtration, takes supernatant, concentration, and spray drying obtains Olive leaf P.E。

Described wetting agent is any one in ethylene glycol, propylene glycol, glycerol, Polyethylene Glycol。

Described fresh-preservative preparation process is as follows:

(1) first sucrose 15 30g and gluconate 0.4 1g, Olive leaf P.E 0.3 1.5g are added in 50 DEG C of distilled water of 500ml, stir 3 hours；

(2) by step 1 mixture be cooled to 20 DEG C, add wetting agent 0.2 0.8g, preservative 0.1 0.5g, stir 0.5 hour, interpolation distilled water, obtain finished product。

Some amino acid pattern that described Olive leaf P.E, the carnosine wherein contained, certain special virus of severe interference, antibacterial or growth of microorganism are required；Described wetting agent has polymeric membrane and reduces transpiration, to close the part holes on flower, reduces the transpiration of flower moisture, extends and spends withered withering to penetrate and regulate the effect of fresh-keeping liquid pH, keeps pattern gorgeous and the life-span is spent in prolongation；Described preservative, in order to kill or to suppress the breeding of microorganism, reduces the physiological blocking of scape, promotes water balance, it is suppressed that the generation of ethylene；Described gluconate trace element is applied to for flower fresh-keeping in, it is more easy to after finding glucose acidifying and is absorbed by flowers, trace element plays a role and becomes apparent from, than independent using glucose, trace element salt or use in conjunction glucose, trace element salt in kind of blooming period prolonging substantially good, the florescence is obviously prolonged 5-10 days；Described sucrose is the energy substance of flower live body, in order to augment the storage of sugar in quirk, plays enhancing assimilation, it is suppressed that the generation of harmful substance and the restriction effect such as transpiration rate in metabolic process。

The invention have the benefit that and present invention employs new bio antistaling agent, it is the fresh-keeping product of flower of a kind of nonhazardous, the absorption of flower it is more easy to the form of gluconate, can the trace element of more effective supplementary flower, flowers are harmless, and low cost, raw material are easy to get, adapted facilitates, use simple。
