Embodiment 1

[0067] Example 1 Thymol: β-cyclodextrin = 0.5:1

[0068] A preparation method of β-cyclodextrin / thymol embedding material includes the following steps:

[0069] (1) Dissolve 4g of β-cyclodextrin in 40 mL of water and stir it magnetically at 80°C for 10 min to obtain β-cyclodextrin solution;

[0070] (2) Dissolve 2 g of thymol in 15 mL of ethanol and mix well to obtain a thymol solution;

[0071] (3) Add the thymol solution to the β-cyclodextrin solution while stirring, and magnetically stir at 60°C for 4 hours to obtain a mixed solution;

[0072] (4) After the mixture is naturally cooled to room temperature, put it in the refrigerator and stand for 12 hours until the white powder precipitated at the bottom of the Erlenmeyer flask no longer increases; vacuum filtration with a circulating vacuum pump, and then water and absolute ethanol during the filtration After rapid washing, the obtained white powder is dried in a vacuum dryer to a constant weight to obtain β-cyclodextrin / thymol embe...

Embodiment 2

[0073] Example 2 Thymol: β-cyclodextrin=1:1

[0074] The dosage of thymol in Example 1 was adjusted to 4 g, and other parameters were kept unchanged to obtain β-cyclodextrin / thymol embeds.

Embodiment 3

[0075] Example 3 Thymol: β-cyclodextrin=2:1

[0076] A preparation method of β-cyclodextrin / thymol embedding material includes the following steps:

[0077] (1) Dissolve 4g of β-cyclodextrin in 40 mL of water and stir it magnetically at 80°C for 10 min to obtain β-cyclodextrin solution;

[0078] (2) Dissolve 8 g of thymol in 15 mL of ethanol and mix well to obtain a thymol solution;

[0079] (3) Add the thymol solution to the β-cyclodextrin solution while stirring, and magnetically stir at 60°C for 4 hours to obtain a mixed solution;

[0080] (4) After the mixture is naturally cooled to room temperature, put it in the refrigerator and stand for 12 hours until the white powder precipitated at the bottom of the Erlenmeyer flask no longer increases; vacuum filtration with a circulating vacuum pump, and then water and absolute ethanol during the filtration After rapid washing, the obtained white powder is dried in a vacuum dryer to a constant weight to obtain β-cyclodextrin / thymol embedded...

Abstract

The invention discloses a preparation method of a thymol embedded intelligent antibacterial preservative film, and belongs to the technical field of fruit and vegetable preservation. The preparation method of the beta-cyclodextrin / thymol embedded material comprises the following steps: (1) dissolving beta-cyclodextrin in water to obtain a beta-cyclodextrin solution; (2) dissolving thymol in ethanol, and uniformly mixing to obtain a thymol solution; (3) adding the thymol solution into the beta-cyclodextrin solution, and stirring for 4 hours at 60 DEG C to obtain a mixed solution; and (4) cooling the mixed solution, and then carrying out suction filtration, washing and drying to obtain the beta-cyclodextrin / thymol embedded material. The problems of high fruit fresh-keeping difficulty, easy rotting, unstable polyphenol, strong smell and the like in the prior art are solved, the process is simple and suitable for industrial production, and the preservative film can be applied to intelligent packaging.

Description

Technical field [0001] The invention relates to a preparation method of an intelligent antibacterial fresh-keeping film for thymol embedded materials, which belongs to the technical field of fresh-keeping of fruits and vegetables. Background technique [0002] According to statistics, in China, the annual loss rate of fruit products in the circulation links such as picking, transportation and storage is as high as 25% to 30%. Among them, there are 12 million tons of rotten fruits on the transportation road, while the loss rate of fruits in developed countries is controlled. Within 5%, the United States is only 1%-2%. The most important reason for the loss of fruit rot in China is the imperfect preservation technology and equipment. Therefore, the research on fruit preservation technology is a hot spot in China and has great development prospects. [0003] Strawberry is a perennial herb of Fragaria L. in the Rosaceae family. It has a delicious taste and high vitamin C content. Str...
