Problems solved by technology

[0004] At present, the fresh-keeping method of cut flowers is mainly based on inorganic chemical preservation. Most of the preservatives contain ethylene antagonists such as silver nitrate and silver thiosulfate, which are not only expensive, but also silver ions are harmful to the human body and easy to pollute the environment.
In addition, there are large metabolic differences among cut flower varieties, and there are few broad-spectrum preservatives (most preservatives are specific, and one preservative can only be used for one or several fresh cut flowers). Therefore, look for efficient cut flower preservatives appears to be particularly important

Abstract

A fresh cut flower antistaling agent and a preparing method thereof are provided. The antistaling agent comprises antistaling components and promoting components. The antistaling components comprise ethyl pyruvate, citric acid, sodium lactate, chitosan, acetic acid, sorbic acid, sucrose ester and water. The promoting components comprise polyethylene glycol, sodium bicarbonate, potassium dihydrogen phosphate, ethylene carbonate, alpha-aminoisobutyric acid and absolute ethanol. The preparing method includes separately preparing the antistaling components and the promoting components, adding the promoting components into the antistaling components, and fully mixing the materials by stirring to obtain the antistaling agent. The antistaling agent is simple in preparing method, easily available in raw materials, low in cost, nontoxic, and capable of effectively maintaining the bright-color period of the fresh cut flower and has good preservation functions especially for cut flowers requiring a long transportation period.

Description

technical field [0001] The invention belongs to the technical field of fresh-cut flowers preservation, and in particular relates to a fresh-cut flower preservation agent and a preparation method thereof. Background technique [0002] The flower industry is an emerging industry in my country. Although it started late, it has developed rapidly. As an important part of the flower industry, cut flowers have broad prospects. With the development of society and economy, the consumption of cut flowers is becoming more and more vigorous. Therefore, it is very important to ensure the good quality of cut flowers. [0003] In recent years, the planting area of ​​cut flowers in the country has been increasing day by day, and its output has also risen by leaps and bounds. There is a relatively complete market system for the production, supply and marketing of cut flowers, and it has a good development prospect. But at present, the flowering period and lifespan of cut flower products are...
