Example Embodiment

[0011] Example 1 Preparation of silk fibroin solution

[0012] (1) Degumming of silkworm cocoons

[0013] Take 10g of silkworm cocoons, 5g of anhydrous sodium carbonate, 5g of soap, put them into 1000mL of boiling water and heat for 1h, then remove the silk, wash it with distilled water, and repeat the above process to make the cocoon degumming rate higher than 30%. Then, the washed silk is taken out and dried to obtain silk fibroin fiber.

[0014] (2) Preparation of silk fibroin solution

[0015] First prepare 42%CaCl by mass percentage 2 The solution, the solution and the silk fibroin fiber obtained in step 1) are added to an Erlenmeyer flask at a ratio of 1:10, and placed in a shaker water bath at 80°C until the silk fibroin is completely dissolved. The solution was poured out and filtered with gauze, and centrifuged at 4°C and 10000r / min for 15min. The centrifugal fluid is put into the pretreated dialysis bag (molecular weight 3500) and placed in deionized water for dialysis for...

Example Embodiment

[0016] Example 2

[0017] The silk fibroin obtained in Example 1 was configured as a fresh-keeping agent for fresh flowers containing 0.1% silk fibroin aqueous solution in terms of mass percentage.

Example Embodiment

[0018] Example 3

[0019] The silk fibroin solution obtained in Example 1 was configured as a fresh-keeping agent for fresh flowers containing 1.0% silk fibroin aqueous solution by mass percentage.

Abstract

The invention provides a preservative agent for a fresh flower. The preservative agent is mainly prepared by adding glycerol and calcium chloride solution at certain concentrations to a 0.5% fibroin solution. The invention also provides a preservative method for the fresh flower and an application of the preservative agent in the course of red rose preservation. With the adoption of the preservative agent and the preservative method, air holes on the surfaces of petals can be closed appropriately, and a pervaporation flux of a membrane can be controlled, so that the effect of preserving the fresh flower is achieved.

Description

Technical field [0001] The invention relates to a storage and fresh-keeping technology for fresh flowers, in particular to a fresh-keeping agent and fresh-keeping method and application for fresh flowers. Background technique [0002] In addition to being used for ornamental purposes, flowers also have important development and utilization values ​​for medicinal, edible and daily chemical industries. However, short flowering period and difficult storage have become the biggest obstacle to the utilization of flower value. [0003] At present, there are many methods for keeping flowers fresh, such as low-temperature storage, controlled atmosphere storage, and reduced-pressure storage. However, these physical methods will cause the air humidity to drop, and the flowers will lose water continuously, the stress resistance will decrease, the loss and the incidence of decay will increase. And this kind of storage space with a certain low temperature and decompression function will furth...
