preparation example Construction

[0020] The preparation method of the composite plastic wrap based on plant source extractant comprises the steps:

[0021] S1, the preparation of fig leaf extract:

[0022] S11. Rinse the collected fig leaves repeatedly with clear water and dry them in the air, dry them in a constant temperature drying oven at 80° C. to a constant weight, pulverize them into powder with a universal pulverizer, and pass through an 80-mesh sieve to obtain plant dry powder;

[0023] S12. Accurately weigh 10.0 g of the obtained plant dry powder into a 100 mL Erlenmeyer flask, add ethanol with a mass fraction of 70% at a material-to-liquid ratio of 1 g: 10 mL, place in an ultrasonic cell pulverizer, and extract at 35° C. for 30 min;

[0024] S13. After the extraction is completed, draw the extract from the upper part of the triangular flask and put it into a rotary evaporator for vacuum distillation to eliminate the influence of 70% ethanol as the extraction solvent. After distillation, use high-pu...

experiment example

[0030] Extraction method and optimization of fig leaf extract: use ultrasonic cell pulverizer to extract, and optimize the concentration of extract solution, solid-liquid ratio, extraction time and extraction temperature through orthogonal experiments, and the extraction method suitable for fig leaf is 70% Ethanol, solid-liquid ratio 1g: 10mL, 35°C, put it into an ultrasonic cell pulverizer for extraction for 30min.

[0031] Bacteriostasis test of fig leaf extract: isolation, purification and identification of fungal diseases during storage of Hami melon. Finally, the fungal strains for the storage period of cantaloupe were obtained: Fusarium, Alternaria and Penicillium. The antibacterial test of the fig leaf extract was carried out on the three strains by using the agar block inhibition zone method. The test results showed that the inhibition rates were as high as 77.78%, 84.29% and 75.46%, respectively.

Abstract

The invention discloses a composite fresh-keeping film based on a plant extract agent as well as a preparation method and application of the composite fresh-keeping film. The fresh-keeping film consists of a extracting agent from plant leaves by ultrasonic extraction, sodium alginate, citric acid and a sucrose ester composite solution and is prepared through the following steps of thoroughly cleaning collected fig leaves, performing airing, performing drying at 80 DEG C until constant weight is obtained, performing crushing to obtain powder, and performing filtering with an 80-mesh sieve; adding 70% of ethanol in proportion to a triangular flask, and placing the added ethanol in an ultrasonic wave cell crusher; after extraction, absorbing an upper extracting solution in the triangular flask for reduced pressure distillation, and eliminating influence of an extraction solvent; after distillation, settling the volume with high-purity water; diluting a 1g / mL mother solution of the fig leaf extracting solution to 80mg / mL, mixing the diluted solution with 1.5% of sodium alginate, 500mg / L of citric acid and 0.5% of sucrose ester in proportion of the diluted solution to the sodium alginate to the citric acid to the sucrose ester being 1 to 1 to 1 to 1, and performing uniform stirring so as to obtain the composite film fresh keeping agent. The fresh keeping film, disclosed by the invention is an edible biological fresh keeping film being selected from plants, and safe, and can restrain growth of fungi.

Description

technical field [0001] The invention relates to fresh-keeping technology, in particular to a composite fresh-keeping film based on a plant source extractant and its preparation method and application. Background technique [0002] With the structural adjustment of Xinjiang's agricultural industry, the Hami melon industry has developed rapidly. However, Xinjiang is located in the west of my country, and the loss of cantaloupe caused by long-distance transportation after harvest is a huge problem. In addition to the high temperature and high humidity environment in summer, postharvest physiological metabolism is strong, and it is easy to be infected by microbial pathogens and rot. It is reported that Xinjiang Hami melon will lose between 5% and 15% after long-distance transportation and short-term storage at the sales place. In the resale process, 3%-5% loss occurs through intermediate links such as wholesale and distribution, which seriously affects the development of the Ha...
