Abstract
The invention provides a preservation method for harvested persimmons by utilizing ascorbic acid. The method comprises the following steps of (1) preparing an ascorbic acid solution the concentration of which is 5%-10%; and (2) accumulating the ascorbic acid solution prepared in the step 1 by using degreasing cotton, placing the degreasing cotton on a persimmon fruit sepal region, completely covering the persimmon fruit sepal, during storage period after harvesting, replacing the degreasing cotton every three days, and replenishing the equivalent newly prepared ascorbic acid solution. The preservation method provided by the invention has the advantages that a safe, effective and convenient preservation technological means is created by utilizing the characteristic of a natural preservative of the ascorbic acid, and the preservation method has wide popularization and application prospects in the preservation link during storage and transportation after harvesting in the industry chain of persimmons.
Description
Technical field
The present invention relates to agriculture field, relate in particular to a kind of ascorbic acid that utilizes and carry out the preservation method after persimmon is really adopted.
Background technology
Persimmon is processed in the process that reaches edible state often easily softening after harvesting or through taking away the puckery taste, and post-harvest fresh-keeping sport technique segment weakness has greatly limited transportation at home and abroad and the circulation of persimmon fresh fruit, is one of key issue of the current persimmon industry development of restriction.And in the fresh-keeping link of postharvest storage (transportation) of persimmon industry, there is no preservation technique measure safely and effectively at present.
Summary of the invention
The object of the invention is to solve the defect that above-mentioned prior art exists, provide a kind of ascorbic acid that utilizes to carry out the preservation method after persimmon is really adopted.
Utilize ascorbic acid to carry out the preservation method after persimmon is really adopted, comprise the following steps:
(1) ascorbic acid solution that, compound concentration is 5%-10%;
(2), use absorbent cotton to accumulate the ascorbic acid solution of preparation, absorbent cotton is positioned over to persimmon fruit sepal region, and sepal is covered completely, every 3 days of postharvest storage phase was changed absorbent cotton and also adds the ascorbic acid solution of the new preparation of equivalent.
Further, the ascorbic acid that utilizes as above carries out the preservation method after persimmon is really adopted, and the use amount that the middle absorbent cotton of step (2) is accumulated the ascorbic acid solution of preparation is each persimmon fruit 3ml-8ml.
Further, the ascorbic acid that utilizes as above carries out the preservation method after persimmon is really adopted, the long 50mm-60mm of described absorbent cotton, wide 50mm-60mm, thick 5mm-15mm
The present invention, by using Exogenous Ascorbic Acid, suppresses to adopt rear fruit ethene synthetic, and effectively the softening progress of delayed fruit, reaches post-harvest fresh-keeping effect.
The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below the technical scheme in the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
The preparation of ascorbic acid solution reagent:
L-AA, CAS 50-81-7, chemical formula C
6h
8o
6, white or faint yellow solid powder, SILVER REAGENT, is 5% solution by its water-soluble concentration that is formulated as.
2, application process
Reagent matching while using, uses after preparation immediately.
Use absorbent cotton (being about 55mm, wide about 55mm, thick about 10mm) to accumulate reagent (5ml/ fruit), be positioned over persimmon fruit sepal region, and sepal is covered completely, every 3 days of postharvest storage phase was changed absorbent cotton and added the reagent of the new preparation of equivalent.
Embodiment 2:
The preparation of ascorbic acid solution reagent:
L-AA, CAS 50-81-7, chemical formula C
6h
8o
6, white or faint yellow solid powder, SILVER REAGENT, is 10% solution by its water-soluble concentration that is formulated as.
2, application process
Reagent matching while using, uses after preparation immediately.
Use absorbent cotton (being about 55mm, wide about 55mm, thick about 10mm) to accumulate reagent (3ml/ fruit), be positioned over persimmon fruit sepal region, and by the complete overlay area of sepal, every 3 days of postharvest storage phase was changed absorbent cotton and added the reagent of the new preparation of equivalent.
Embodiment 3:
The preparation of ascorbic acid solution reagent:
L-AA, CAS 50-81-7, chemical formula C
6h
8o
6, white or faint yellow solid powder, SILVER REAGENT, is 8% solution by its water-soluble concentration that is formulated as.
2, application process
Reagent matching while using, uses after preparation immediately.
Use absorbent cotton (being about 55mm, wide about 55mm, thick about 10mm) to accumulate reagent (8ml/ fruit), be positioned over persimmon fruit sepal region, and by the complete overlay area of sepal, every 3 days of postharvest storage phase was changed absorbent cotton and added the reagent of the new preparation of equivalent.
Comparative example 1:
Use absorbent cotton (being about 55mm, wide about 55mm, thick about 10mm) to accumulate distilled water (8ml/ fruit), be positioned over persimmon fruit sepal region, and by the complete overlay area of sepal, every 3 days of postharvest storage phase was changed absorbent cotton and added equivalent distilled water.
Because the transpiration of persimmon sepal causes water stress can accelerate fruit softening, so cover moisture absorbent cotton, slow down water stress to be conducive to a certain extent persimmon fresh-keeping.
Comparative example 2:
To plucking rear fruit, do not do any processing, normally place.
Below persimmon in embodiment and comparative example is really plucked to commodity after the 30th day fruit rate (%), average softness number (being divided into 1,2,3,4 four rank), average ethylene growing amount (nL/gh), average endogenous ascorbic acid content (mg/100gfw) and is done comparative analysis, obtain table one:
Table one:
Conclusion: supplement the technology of ascorbic acid by implementing external source, improve the endogenous ascorbic acid content of fruit, ethene suppressing generates, the softening progress after delaying persimmon and adopting, has significantly improved commodity fruit rate.
Patent appliable plant of the present invention itself can endogenous generation ascorbic acid as antistaling agent, can guarantee its natural, security.By clear and definite its fresh-keeping mechanism of interaction between ascorbic acid and cell wall degradation and ethene in excavation fruit, and determine the valid density that its external source is used.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
