Fresh-keeping agent for fresh cut flowers and preparation method of such fresh-keeping agent

Abstract

The invention discloses a fresh-keeping agent for fresh cut flowers. The fresh-keeping agent is prepared from fresh orange peel, saccharose, zinc acetate, abscisic acid, chitosan, a compound bio-enzyme preparation, glycerol monolaurate, glycerol monocaprylate, propylene glycol, Tween 20, edible glacial acetic acid and the like. The fresh-keeping agent for the fresh cut flowers has the advantages that the fresh-keeping agent avoids addition of harmful chemical components and can form a thin film of a porous network structure on the surface of every petal after being sprayed and coated on the surfaces of the fresh cut flowers, so that external moisture exchange is stopped, water loss is delayed, and withering caused by water loss of flowering branches is delayed; when used as a nutrient solution, the fresh-keeping agent is rich in nutrient, so that antibacterial effects are achieved, safety of cutting edges of the cut flowers is ensured, and decline in the flower quality due to bacterial infection is avoided.

Description

technical field

[0001] The invention relates to the field of cut flower preservation technology, in particular to a fresh cut flower preservation agent and a preparation method thereof. Background technique

[0002] With the rapid development of society and economy, the continuous improvement of people's quality of life and the gradual improvement of the environment, the demand for flowers is constantly increasing. my country's flower culture has a long history and rich heritage, and the people's flower appreciation level is also constantly improving, which is very beneficial to expanding flower consumption, among which fresh-cut flowers are an important flower consumption mode.

[0003] The freshness of cut flowers is an important indicator of the quality of cut flowers. Cut flowers are still living organisms after being cut, and undergo a series of complex metabolic processes and physiological changes. After cut flowers leave the plant mother body, they are mainly affecte...

Embodiment Construction

[0019] A fresh-cut flower preservative prepared by the following method:

[0020] (1) Take fresh orange peel and wash it, cut it into small pieces, put it into an ethanol solution with a volume concentration of 50% according to the ratio of solid to liquid 1:8g / mL, heat it up to 80°C and extract it under reflux in a water bath for 1 hour, and the obtained The extract is filtered, and the obtained extract is freeze-dried into a powder for subsequent use;

[0021] (2) Prepare raw materials chitosan 14, composite biological enzyme preparation 1, lauric monoglyceride 4, monocaprylic glyceride 12, propylene glycol 18, soil temperature 20 8, food grade glacial acetic acid 10 in parts by weight, the composite biological The enzyme preparation is made of alkaline pectinase and cellulase with a weight ratio of 1:2. First, the chitosan is immersed in water, and at the same time, a compound biological enzyme preparation is added to it, and the mixture is heated to 45°C. Refining treatme...
