Abstract
The invention discloses a preparation method of a novel edible film-coated fruit and vegetable fresh-keeping agent. The preparation method comprises the following steps: respectively weighing 10-18 parts of pectin, 8-15 parts of glucose, 3-8 parts of tea polyphenol, 5-15 parts of carboxymethyl chitosan, 3-8 parts of Vc-sodium, 0.5-2 parts of natamycin, 3-8 parts of citric acid and 10-20 parts of ethyl alcohol according to the formula, and dissolving the components in matching amount of water at 30-50 DEG C to prepare the edible film-coated fruit and vegetable fresh-keeping agent. The fresh-keeping system prepared by the preparation method disclosed by the invention is aqueous, easy to store, safe and nontoxic, forms a very thin film on the surfaces of fruits and vegetables, has the advantages of good broad-spectrum bacteriostasis and sterilization properties, oxidation resistance, browning prevention, long fresh-keeping period and good moisturizing agent and is edible and nontoxic.
Description
technical field:
The present invention relates to a kind of fruit and vegetable fresh-keeping agent, particularly a kind of preparation method of novel feeding habits coated preservative for fruits and vegetables.
background technology:
Fruit and vegetable is the indispensable living materials of the mankind, but the production of fruits and vegetables has very strong seasonality and region, and physiologically active is high, water content is large, springy texture, perishablely mildews, freshness declines, and brings very large difficulty therefore to the fresh-keeping of fruits and vegetables and circulation.Postharvest technology of fruits and vegetables has at present: low temperature controlled atmosphere method, and this method is expensive; Inner wrapping is fresh-keeping, and it is slow that oxygen speed falls in this method, and fresh-keeping effect is poor; Chemical preservative method, due to have toxic and side effect chemical agent residual, not easy cleaning remove affect health, therefore, safety, nontoxic, the exploitation of natural fruit and vegetable fresh-keeping agent, application prospect is very extensive.CN02157908.3 discloses a kind of antibrown type fruits and vegetables and has been coated with by antistaling agent and preparation method thereof, and the antibacterial sterilizing ability of the made antistaling agent of this method is poor.CN2007100515.6 discloses a kind of browning preventing broad spectrum fruit preservative, the lock water poor-performing of the prepared antistaling agent of this method to fruit, and fruit dehydration is high.CN200710045893.1 discloses carboxymethyl chitosan fruit preserving coating agent and preparation method thereof, and the uses such as this antistaling agent needed raw material glycerine, Tween 80 have certain standard, can not exceed standard edible.
summary of the invention:
Goal of the invention: for the defect of prior art, provide a kind of safe, nontoxic, nuisanceless, built agent cooperative effect is good, broad-spectrum antibacterial sterilization, the anti-soft rotten performance of anti-brown stain is good, the preparation method of edible natural film composite antistaling agent for fruits and vegetables with low cost.
To achieve the object of the present invention, a kind of preparation method of novel feeding habits coated preservative for fruits and vegetables, takes following technical formula:
Title weight portion
10～18 parts of pectin
8～15 parts of glucose
3～8 parts of Tea Polyphenols
5～15 parts of CMCs
Vc-sodium 3～8
Natamycin 0.5～2
Citric acid 3～8
10～20 parts of ethanol
900～960 parts, water
The preparation method of described a kind of novel feeding habits coated preservative for fruits and vegetables, take respectively pectin, glucose, Tea Polyphenols, CMC, Vc-sodium, natamycin, citric acid, ethanol, at 30～50 ℃, be dissolved in the water of proportional quantity, make edible film-coating fruit and vegetable fresh-keeping agent.
The preparation method of described a kind of novel feeding habits coated preservative for fruits and vegetables, take respectively pectin 15g, glucose 12g, Tea Polyphenols 4g, CMC 12g, Vc-sodium 5g, natamycin 1g, citric acid 5g, ethanol 18g, at 30～40 ℃, be dissolved in 946g distilled water, make edible film-coating fruit and vegetable fresh-keeping agent.
Beneficial effect of the present invention: system is water-based, is easy to store, safety non-toxic, and it is good that the film that antistaling agent of the present invention forms at fruit and vegetable surfaces has broad-spectrum antibacterial bactericidal property, the anti-brown stain of antioxygen, long fresh-keeping period, moisture-keeping efficacy is good and edible nontoxic.
the specific embodiment:
Below in conjunction with embodiment, the present invention is done further and described in detail, but the scope of protection of present invention is not limited to the scope that embodiment represents.
Embodiment 1:
Take respectively pectin 15g, glucose 12g, Tea Polyphenols 4g, CMC 12g, Vc-sodium 5g, natamycin 1g, citric acid 5g, ethanol 18g, at 30～40 ℃, is dissolved in 946g distilled water, makes edible film-coating fruit and vegetable fresh-keeping agent.
Use this antistaling agent to spray or to soak mode processing fruits and vegetables, form film layer as thin as a wafer, effectively reduce respiratory intensity and the transpiration of fruits and vegetables, prevent brown stain, broad-spectrum antibacterial sterilization, thereby the freshness of maintenance fruits and vegetables, extend the shelf-life of fruits and vegetables, this product is edible nontoxic.
Embodiment 2:
Take respectively pectin 12g, glucose 15g, Tea Polyphenols 6g, CMC 10g, Vc-sodium 4g, natamycin 1g, citric acid 4g, ethanol 15g, at 30～40 ℃, is dissolved in 930g distilled water, makes edible film-coating fruit and vegetable fresh-keeping agent.
Embodiment 3:
Take respectively pectin 10g, glucose 10g, Tea Polyphenols 8g, CMC 15g, Vc-sodium 8g, natamycin 1g, citric acid 4g, ethanol 15g, at 30～40 ℃, is dissolved in 930g distilled water, makes edible film-coating fruit and vegetable fresh-keeping agent.
