Abstract
The present invention relates to the technical field of biochemistry, particularly to fruit antistaling agent. The fruit antistaling agent contains natural abscisic acid and iturin. The antistaling agent prepared by natural green substance has advantages of good fresh-keeping effect, no pollution and so on.
Description
Technical field
The invention belongs to technological field of biochemistry, be specifically related to a kind of fruit antistaling agent.
Background technology
Behind the fruit picking,, be subjected to the infringement of pathogen easily, cause and rot, or, lose edibility because dehydration is withered owing to its surface moisture, sugar part, protein content height.Therefore, good fruit post-harvest fresh-keeping technology is the problem of countries in the world scientist research always.
Existing fruit antistaling agent only pays attention to preventing that the fruit dehydration is withered, and lacks adopting effective prophylactico-therapeutic measures of back pathogenic microorganism, and therefore, fresh-keeping effect is very limited; And the antistaling agent composition of taking seldom adopts the material of natural green to prepare antistaling agent based on synthetics.
Iturin (Iturin) comes from the microorganism secondary metabolite, and basic structure (Chemical formula 1) is a cyclic peptide of being made up of 7 a-amino acids, is beta-amino aliphatic acid at the N-end.It is nontoxic, nuisanceless, environmentally friendly, has broad spectrum resistance simultaneously and advantage such as be difficult for developing immunity to drugs, and is considered to a kind of antibacterial peptide natural, that have efficient inhibition plant pathogenic fungi.
The structure of Chemical formula 1 .Iturin A
The inventor finds under study for action, iturin has the wide spectrum antagonism to the fruit pathogen, as to mango anthrax-bacilus (Colletotrichum gloeosporioides), apple, grape anthracnose [Glomerellacingulata (Stonem.) Spauld.et Schrenk], ring rot of apple bacterium (Botryosphaeriaberengeriana), Monilinia fructicola (Monilinia laxa (Aderh.et Ruhl.) Honey), lichee, longan sour germ (Geotrichum candidum Link), peronophythora litchi bacterium (Peronophthora litchiChen ex Ko et al.) citrus Penicillium notatum (Penicillium italicum), citrus green mold bacterium (Penicilliumdigitaum), after grape grey mould bacterium fruit such as (Botrytis cinerea) is adopted, the storage life disease, has the spore germination of efficient inhibition pathogen, suppress mycelial growth, prevent and treat action effects such as disease generation.
Natural abscisic acid (S-ABA), agricultural chemicals common name: S-abscisic acid, molecular formula: C
15H
20O
4, chemical name is: and 5-(1 '-hydroxyl-2 ', 6 ', 6 '-trimethyl-4 '-oxo-2 '-cyclohexene-1 '-yl)-3-methyl-2-is suitable-and 4-is anti--pentadienoic acid, chemical structural formula is as follows
The structural formula of Chemical formula 2 .S-ABA
Abscisic acid was extracted from the cotton young fruit by people such as Addicott first in 1963.Realized its suitability for industrialized production by Chengdu Inst. of Biology, Chinese Academy of Sciences in 1999.Three during the last ten years, and the various countries scientist has carried out research extensively and profoundly to the physiologically active of plant effect of abscisic acid.Result of study shows that abscisic acid is plant " antitranspirant ", can the inducing plant blade, the fruit surface stomatal closure, weaken transpiration, reduce water evaporates and scatter and disappear, suppress the physiological maturity process, the infringement of opposing pathogen, the freshness of maintenance plant leaf blade, fruit.
Gamma-polyglutamic acid-(γ-PGA) be a kind of can be by the synthetic amino acid polymer of microorganism large number of biological, it is formed by connecting by the CO amido link by D type or L type glutamic acid, structural formula such as chemical formula 3.
The structural formula of chemical formula 3. γ-PGA
Synthetic γ-the PGA of microorganism is a kind of water miscible biodegradable boiomacromolecule, and it is made up of 5000 left and right sides glutamic acid monomers usually, and relative molecular mass is bioabsorbable polymer materials nontoxic, environmental protection generally 100,000～1,000,000.γ-PGA and derivative thereof can be widely used as the hydrogel of medicament slow release material, food, and high strength fibre etc.; At field of food, gamma-polyglutamic acid-has foodsafety, can be used as dietary fiber, health food, food thickening agent, stabilization agent or as the NMF of used for cosmetic; In addition, gamma-polyglutamic acid-will have high water absorbing capacity after processing, and can absorb water reaches 3,500 times, extremely be suitable for agricultural soil and environment-friendly products and use.As, at fertilizer, herbicide when pest repellant etc. use, adds an amount of gamma-polyglutamic acid-salt and can prolong these medicines in the lip-deep time of staying of effective object, is difficult for because of the very fast inefficacy of drying or rains being washed away; Utilize the gamma-polyglutamic acid-can also be as the carrier or the sustained release agent of medicine, make certain formulation, the rate of release of control medicine in human body makes the dosage of medicine according to design, in the time that requires, discharge in vivo, to reach the purpose of effective treatment by certain speed.
The present application people is surprised to find under study for action, certain density iturin is mixed in proportion with certain density natural abscisic acid, with the gamma-polyglutamic acid-is carrier or sustained release agent, method such as adopt even spraying, spraying, flood, film, form the pastille film at fruit surface, can play extraordinary fresh-keeping effect, so finished the present invention.
Summary of the invention
Purpose of the present invention, provide a kind of novel fruits fresh-keeping agent of highly effective and safe, this antistaling agent can form one deck and hold the fungi-proofing film of effect on the pericarp surface, induce the pericarp stomatal closure simultaneously, water evaporation quantity is reduced, can effectively prevent fruit to adopt the back and the storage life goes mouldy owing to pathogen encroaches on, rot, prevent that fruit surface is owing to a large amount of dehydrations wrinkle that contracts is rotten, reduce its respiratory intensity, suppress the activity of flesh cell endoenzyme, saccharic acid content is underspeeded slow down, make fruit keep best in quality and freshness in the storage life, its color and luster, it is good that nutritional labeling and moisture keep, and the storage time looks the types of fruits difference and can prolong 1 times to more than 3 times.
