Description

Preservative based on cypress oil alcohol and magnolia polyphenol and preparation method thereof
Technical Field
The invention relates to the technical field of fruit and vegetable preservation, and particularly relates to a preservative based on cypress oil alcohol and magnolia polyphenol and a preparation method thereof.
Background
The fruit and vegetable products have higher nutritional value, and along with the continuous improvement of living standard, the demand and quality of the fruit and vegetable products in the life of people are increased year by year. The fruit and vegetable products are fundamentally different from agricultural products such as grains, and the requirements of the fruit and vegetable products on freshness are higher. The fruit and vegetable products have higher requirements on the preservation technology due to high water content and vigorous respiration and transpiration. The main causes of the deterioration and the decay of the fruit and vegetable products comprise the invasion of external diseases and the physiological activities of the fruit and vegetable products. In order to inhibit the deterioration and the decay of fruit and vegetable products and prolong the commodity thereof, the method must start from two aspects of inhibiting the invasion of exogenous diseases and the physiological activities of the fruits and the vegetables. At present, great progress is made in the aspects of physical preservation technologies such as refrigeration preservation, modified atmosphere preservation, radiation preservation and the like in China, however, chemical preservation is slowly developed as an important component of the whole preservation system, and at present, most of preservatives also depend on high-toxicity pesticides such as sulphur products, carbendazim and the like. In view of the above, the patent discloses a novel fruit and vegetable fresh-keeping agent based on low-toxicity medicines such as mangnolia officinalis polyphenol and cypress oleyl alcohol.
In the prior art, for example, the invention patent with the application number of 201610670381.3 discloses an instant vegetable and fruit fresh-keeping bacteriostatic agent, which comprises the following components: 1-3% of chitosan, 0.02-0.1% of hinokitiol, 1-3% of ethanol, 0.1-0.5% of vitamin C and the balance of water, but the preservative effect of berries with high sugar content is poor.
Disclosure of Invention
In order to change the current situation that the existing preservative depends on high-toxicity pesticides such as sulfur products, carbendazim and the like and improve the preservation effect, the invention provides the preservative based on cypress oil alcohol and magnolia polyphenol and the preparation method thereof, and the preservative is realized by the following technical scheme:
a preservative based on cypress oil alcohol and magnolia officinalis comprises 0-7% by weight of cypress oil alcohol and 0-7% by weight of magnolia officinalis polyphenol in the preservative.
Further, the preservative also comprises 0-15% of ethanol, 0-1% of thickening agent, 0-1% of film forming agent and the balance of water by weight percentage.
Further, the thickener is at least one of sodium carboxymethylcellulose, sodium diatomate, gelatin, agar, sodium polyacrylate and diatomite.
Further, the film forming agent is at least one of polyvinyl alcohol, polyethylene glycol, chitosan, polylactic acid, polyglycolic acid and polyvinylpyrrolidone.
A preparation method of a preservative based on cypress oil alcohol and magnolia polyphenol comprises the following steps:
s1, dissolving cypress oil alcohol and magnolia officinalis polyphenol in ethanol at 50-70 ℃, and stirring until the cypress oil alcohol and the magnolia officinalis polyphenol are completely dissolved to obtain an alcohol solution of the cypress oil alcohol and the magnolia officinalis polyphenol;
s2, adding the thickening agent and the film forming agent into deionized water, heating to 70-90 ℃, and stirring until the thickening agent and the film forming agent are completely dissolved to obtain an aqueous solution of the thickening agent and the film forming agent;
s3, adding the alcoholic solution of the cypress oil alcohol and the magnolia bark polyphenol into the aqueous solution of the thickening agent and the film forming agent, and stirring until the alcoholic solution of the cypress oil alcohol and the magnolia bark polyphenol is uniformly dispersed in the aqueous solution of the thickening agent and the film forming agent to obtain the preservative based on the cypress oil alcohol and the magnolia bark polyphenol.
Further, the stirring speed in the above-mentioned S1-S3 was at 300-1200 rpm.
Further, the preservative based on the cypress oil alcohol and the magnolia polyphenol in the S3 contains 0-7% of cypress oil alcohol, 0-7% of magnolia polyphenol, 0-15% of ethanol, 0-1% of a thickening agent, 0-1% of a film forming agent and the balance of water.
Further, the thickener used in S2 is at least one of sodium carboxymethylcellulose, sodium diatomaceous earth, gelatin, agar, sodium polyacrylate, and diatomaceous earth.
Further, the film forming agent used in S2 is at least one of polyvinyl alcohol, polyethylene glycol, chitosan, polylactic acid, polyglycolic acid, and polyvinylpyrrolidone.
The invention has the beneficial effects that the preservative and the preparation method thereof relate to cypress oil alcohol and magnolia polyphenol, and have the effects of obviously reducing the indexes of fruit and vegetable diseases, delaying the reduction of the content of soluble solids in fruits and vegetables, and inhibiting the increase of the content of fatty acid and color change, thereby improving the quality of the fruits and vegetables. The cypress oleyl alcohol and the mangnolia officinalis polyphenol belong to plant-derived broad-spectrum efficient antibacterial agents, and are non-toxic and safe, and the broad-spectrum antibacterial agents are compounded of the cypress oleyl alcohol and the mangnolia officinalis polyphenol, so that the prepared preservative can inhibit the invasion of most exogenous pathogenic bacteria, the capability of fruits and vegetables in inhibiting exogenous diseases is effectively improved, the commercialization period of the fruits and vegetables is prolonged, the food safety risk caused by the use of other chemical preservative residues can be greatly reduced, and the great social benefit is achieved. Through compounding of the cypress oleyl alcohol, the mangnolia officinalis polyphenol, the thickening agent and the film forming agent, the prepared fresh-keeping emulsion can quickly form a layer of compact, firmly-adhered, continuous and uniform film on the surfaces of fruits and vegetables, so that the external pathogen invasion is inhibited, and the water loss of the fruits and vegetables and the abrasion caused by collision in the transportation process can be effectively reduced; in addition, the fruit fresh-keeping agent can keep fresh of berry fruits with high sugar content, such as medlar and the like, of which the conventional fresh-keeping agent effect is not obvious.
