Problems solved by technology

[0003] At present, the main way to keep vegetables fresh is for vendors to spray water or refrigerate. However, the sprayed water is easy to volatilize and is not easily absorbed by the vegetable leaves. The cost of refrigeration is high and there are many restrictions.

Embodiment 1

[0015] The composition and content of the anti-dehydration protective agent for vegetables under the high temperature of the present embodiment are as follows:

[0016] Mannosylglyceric Acid 100g Sorbitan Ester 10g purified water 10L

[0017] The effect of the anti-dehydration protective agent for vegetables of the present embodiment is as follows:

[0018] Application effect in spinach:

[0019] Select 1 kg of fresh spinach, spray 20 ml of the anti-dehydration protective agent of this embodiment, and then place it under the sun for 4 hours at a temperature of 32 degrees Celsius in summer.

[0020]

[0021]

[0022] Experimental results show that spraying this agent can significantly reduce the water loss of spinach under sunlight. It can be seen with the naked eye that the surface of the control group is dry and shriveled, while the embodiment still maintains a relatively sufficient water content, and the leaf surface is relatively erect.

Embodiment 2

[0024] The composition and content of the protecting agent of the present embodiment are as follows:

[0025] Mannosylglyceric Acid 20g Sucrose esters 0.2g purified water 1000ml

[0026] The effect of the anti-dehydration protective agent for vegetables of the present embodiment is as follows:

[0027] Application effect in pea sprouts:

[0028] Get 2kg of pea sprouts, spray 50ml of the anti-dehydration protective agent of this embodiment, and then place it under the sun for 6 hours at a temperature of 33 degrees Celsius in summer.

[0029]

[0030]

[0031] Experimental results show that spraying this agent can significantly reduce the water loss of pea seedlings under sunlight. It can be seen with the naked eye that the control group has been significantly dehydrated, and the bean sprouts are dry and shriveled, while the embodiment still maintains a relatively sufficient water content, and the leaf surface is relatively erect.

[0032]

Embodiment 3

[0034] The composition and content of the protecting agent of the present embodiment are as follows:

[0035] Mannosylglyceric Acid 5g Sucrose esters 0.1g purified water 1000ml

[0036] Application effect in lettuce:

[0037] Take 1kg of lettuce, spray 20ml of the anti-dehydration protective agent of this embodiment, and then place it under the sun for 8 hours at a temperature of 35 degrees Celsius in summer.

[0038] The effect of the anti-dehydration protective agent for vegetables of the present embodiment is as follows:

[0039]

[0040] The realization results show that the lettuce will lose a lot of water after being exposed to the sun for 8 hours at high temperature. After spraying this protective agent, the water loss of lettuce can be significantly reduced.

[0041]

[0042] The preparation method of anti-dehydration protecting agent of the present invention is as follows:

[0043] Dissolve mannosylglyceric acid (0.05wt%~10wt%), sorbi...

Abstract

The purpose of the present invention is to provide an anti-dehydration protective agent for vegetables at high temperature. The agent includes mannosylglycerate, nonionic surfactant and water. The anti-dehydration protective agent for vegetables at high temperature can prevent the vegetables from rapid dehydration and being fade at high temperature exposure in summer by using the mannosylglycerate.

Description

technical field [0001] The invention relates to an anti-dehydration protective agent for vegetables under high temperature, in particular to an anti-dehydration protective agent for vegetables under high temperature with mannosylglyceric acid as the main component. Background technique [0002] Vegetables sold in the open-air market in summer and transported in high-temperature weather can easily lead to rapid dehydration of vegetables, becoming dry, and causing huge losses. Since more than 70% of vegetable sales in my country are still carried out by market vendors, there are moisturizing and heat-preserving shelves in supermarkets. The amount is relatively small. Therefore, studying how to reduce the problem of vegetable dehydration under the condition of dry heat in summer is an urgent problem related to the national economy and the people's livelihood. [0003] At present, the main method to keep vegetables fresh is for vendors to spray water or refrigerate. However, the...
