Embodiment 1

[0030] Each kilogram of flower preservation agent consists of the following components: 5g polyglutamic acid or its salt, 10g glycerol, 1g alum, 4g sucrose, 5g aminooxyethylvinylglycine, 20g sorbitol, and the rest are solvents. It is physiological saline, in which the sodium chloride content per kilogram of physiological saline is 0.75g. The preparation method is as follows:

[0031] (1) First, prepare brine according to 0.75g sodium chloride per kilogram of water, and divide them into three equal parts;

[0032] (2) Weigh 5 g of polyglutamic acid or its salt by weight, turn on the high-speed stirrer, add it to a portion of physiological saline while stirring, until it is completely dissolved, and make solution one;

[0033] (3) Add 1g of alum and 5g of aminooxyethylvinylglycine to the second part of normal saline, stir and dissolve to make solution two;

[0034] (4) Weigh 4g of sucrose, stir and dissolve 20g of sorbitol in the third portion of normal saline, add 10g of glycerin, sti...

Embodiment 2

[0038] Each kilogram of flower preservative consists of the following ingredients: 10g polyglutamic acid or its salt, 5g glycerol, 0.75g alum, 8g sucrose, 6g aminooxyethylvinylglycine, 10g sorbitol, and the rest are solvents. The solvent is physiological saline, in which the sodium chloride content per kilogram of physiological saline is 0.75g. The preparation method is the same as in Example 1, and the prepared fresh flower spray antistaling agent is the same as in Example 1. It can be kept fresh for about 20 days when placed at room temperature and 54 days in a fresh-keeping cabinet.

Embodiment 3

[0040] Each kilogram of flower preservative consists of the following ingredients: 12g polyglutamic acid or its salt, 1g glycerol, 1g alum, 8g sucrose, 4g aminooxyethylvinylglycine, 15g sorbitol, and the rest are solvents. It is normal saline, in which the sodium chloride content per kilogram of normal saline is 0.65g. The preparation method is the same as in Example 1, and the prepared fresh flower spray antistaling agent is the same as in Example 1. It can be kept fresh for about 20 days when placed at room temperature, and for 60 days in the fresh-keeping cabinet.

Abstract

The invention belongs to the technical field of fresh-keeping, and provides a flower spray fresh-keeping agent which is low in cost, and excellent in effects, and is convenient to use. One kilogram of the flower spray fresh-keeping agent comprises 1 to 20g of polyglutamic acid or a salt of polyglutamic acid, 1 to 10g of glycerinum, 0.15 to 2g of alum, 0.5 to 10g of sucrose, 0.1 to 10g of aminoethoxyvinylglycine, and 1 to 20g of sorbitol. Water-retaining property of polyglutamic acid or the salt of polyglutamic acid in the flower spray fresh-keeping agent is extremely high; intelligent moisture retention in environment with different temperature and humidity can be realized; the flower spray fresh-keeping agent possesses no toxicity or harm, and is high in biocompatibility; flowers processed using the flower spray fresh-keeping agent are long in self life, fading is slow, freshness of flower appearance and smell can be maintained for a long term, economic loss caused in fresh flower transportation and storage processes is reduced greatly, and fresh flower ornamental quality is improved.

Description

technical field [0001] The invention relates to a flower fresh-keeping agent containing polyglutamic acid or its salt, which is used for fresh-keeping of picked flowers. Background technique [0002] With the development of my country's economic level, people's living taste and requirements for quality of life have been greatly improved. Along with all this, the flower industry, a new type of industry, has risen rapidly in my country, and flowers have played an increasingly important role in people's daily life. The more important the role, it has gradually become a medium for people to convey friendship and express wishes, so the demand for flowers in our country is also increasing rapidly. But most of flowers will be eclipsed after plucking, even wither, so the fresh-keeping work of flowers after plucking just seems particularly important, so the development of a kind of reasonable and effective preservative just seems imminent. [0003] After the flower leaves the parent ...
