Description
Technical field
The present invention relates to Research Progress of Keeping Fresh Technology of Cut Flowers fields more particularly to a kind of fresh cut-flower antistaling agent and preparation method thereof.
Background technique
With society and economic fast development, the continuous improvement of people's living standard and the gradually improvement of environment, flower
Grass demand constantly increases.China's flowers cultural and historical is long, and inside information is abundant, and the flowers of the people appreciate level also not
It is disconnected to improve, this to expand flowers consumption be it is highly beneficial, wherein Fresh Cutting flower is the important flowers consumption mode of one kind again.
The fresh and alive degree of cut-flower is an important symbol of cut-flower quality.Cut-flower is adopted cut after be still lived organic
Body carries out the metabolic process and physiological change of a series of complex, after cut-flower leaves plant parent, mainly by following several factors
Influence: (1) lack of moisture；(2) organic nutrient, vitamin and mineral element supply are insufficient；(3) the mechanical damage of cutting trimming
Wound；(4) harmful microorganism infects；(5) change of the external environments such as in vitro rear temperature, humidity, illumination, ventilation；(6) endogenous hormones
It is out of control etc..These reasons result in cut-flower ratio, and to stay on maternal plant aging rotten faster.
It is generally used currently, Fresh Cutting flower in the market is fresh-keeping by nutriment, fungicide, ethylene antagonist, anti-oxidant
The bottle of the compoundings such as agent and plant growth regulator inserts antistaling agent, and supplement fresh flower as far as possible is detached from the nutrition after parent, prevents Fresh Cutting flower
Go bad eclipsed, but these fresh-keeping liquid ingredients all have configuration complex process, not easy to maintain, higher cost and toxic, different journeys
Undesirable influence is caused on human body and environment on degree.Application No. is 200810049973.9 patent of invention disclose it is a kind of male
Red, herbaceous peony cut flower antistaling agent and its application method, which describe one kind by sucrose, 8-hydroxyquinoline, citric acid, salicylic acid, two
The antistaling agent for cut-flower that chlorine monoxid, silver thiosulfate and water are constituted.After cut-flower is inserted into this antistaling agent 20-30 minutes, its bottle can be made
Service life extension 50-150% or more is inserted, but its chlorine dioxide used has strong corrosive, silver thiosulfate has toxicity, is not suitable for
In the fresh-keeping use of conventional ornamental value Fresh Cutting flower.
The quality of Fresh Cutting flower is production of flowers and plants person, operator, consumer's questions of common interest, how from Antimicrobial preservative,
It is then most important that nutritional supplementation, prevention dehydration etc. synthesis provide a kind of economic, nontoxic, convenient and fast Fresh Cutting flower fresh-keeping liquid.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provides a kind of fresh cut-flower antistaling agent and its preparation side
Method.
The present invention is achieved by the following technical solutions:
A kind of fresh cut-flower antistaling agent, is prepared by the following method:
(1) take fresh orange peel clean after by solid-liquid ratio 1: 8-10g/mL put into volumetric concentration be 50-60% ethyl alcohol it is molten
In liquid, it is heated to 80-90 DEG C and with water-bath refluxing extraction 1-1.5 hours, by extract obtained filtering, obtained extracting solution
Freeze-dried is that powder is spare；
(2) prepare raw materials of chitosan 14-15, composite biological enzyme preparation 1-2, Glyceryl Monolaurate 4-6, list by weight
Glycerol caprylate 12-13, propylene glycol 18-20,20 8-10 of soil temperature, food grade glacial acetic acid 10-12, are first immersed in water for chitosan
In, while composite biological enzyme preparation being added thereto, heat mixed liquor to 45-48 DEG C, refining treatment 40-45 minutes, after the completion
Filter and take out chitosan, first with 60-65 DEG C hot water injection 2-3 times, it is 4-5 minutes each, then rinsed with 20-25 DEG C of water into
Property, by gained chitosan drying after with Glyceryl Monolaurate, Capmul MCM C8, food grade glacial acetic acid, propylene glycol and soil
The mixing jointly of temperature 20, and be stirred continuously, the fully dispersed mixing of mixed liquor is slowly added water to during stirring, adjusts pH to 6.0-6.5,
It is spare to obtain emulsification chitosan；
(3) sucrose is dissolved in the water of 8-10 times of its quality, then by sucrose solution low-grade fever to 30-35 DEG C, to every liter of sugarcane
2-3g zinc acetate, 10-20mg abscisic acid, 4-5g step 1 gained powder and 10-15g are added in sugar juice and emulsifies chitosan, stirs
It mixes uniformly；
(4) step 3 gained mixed liquor is poured into steam sterilization pan, persistently sterilizes 20-30 minutes, takes out nature after the completion
It is cooled to room temperature, packs up to Fresh Cutting flower fresh-keeping liquid of the present invention.
The composite biological enzyme preparation be alkaline pectase and cellulase with the proportional arrangement that weight ratio is 1: 2 and
At.
Fresh orange peel is first cut into fritter after cleaning or smashs to pieces in the step 1, then is extracted with ethyl alcohol, extracts effect to improve
Rate.
Sterilization pressure control is controlled in 0.1-0.12MPa, sterilising temp at 120-130 DEG C in step 4 sterilization process.
The application method of the Fresh Cutting flower fresh-keeping liquid is that Fresh Cutting flower is inserted directly into fresh-keeping liquid or is watered fresh-keeping liquid
Fresh-cut flower surface is sprayed at sprayer after 4-5 times of dilution.
The invention has the advantages that
Fresh Cutting flower fresh-keeping liquid of the present invention avoids the addition of harmful chemical component, takes full advantage of orange peel etc. and plants source property activity
Ingredient collocation emulsification chitosan forms the film of porous network structure, flower in petal surface after fresh-cut flower surface sprays film
Valve surface is capped, prevents the exchange of outside moisture, slows down moisture loss, delays to wilt caused by spray dehydration, together
When emulsify chitosan molecule polar groups amino and hydroxyl presence, have very high affinity and persistence to hydrone,
Cut-flower surface forms well stable humidity environment.Macronutrient is rich in when using as nutrient solution, fungistatic effect is deposited
In the safety for also ensuring cut-flower notch, bacterium infection is avoided to cause colored quality decline.
