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
The present invention relates to the anti-dehydration protection agent of vegetables under a kind of high temperature, especially a kind of with the anti-dehydration protection agent of vegetables under the mannose group glyceric acid high temperature that is main component.
Background technology
The vegetables of market sale in the open in summer and transport vegetables easily cause vegetables fast dewatering under hot weather, become listless dry, cause huge loss, sell more than 70% due to the current vegetables of China and still carry out market street pedlar, there is moisture-heat preservation shelf sale amount relatively few inside supermarket.Therefore, how research reduces dewatering vegetable problem under hot dry conditions in summer is the urgently to be resolved hurrily problem involved the interests of the state and the people.
The fresh method of current maintenance vegetables mainly street pedlar by spraying the mode such as moisture or refrigeration, but spraying moisture is easy to volatilization and not easily by vegetables Foliage Absorption, refrigeration cost is higher, also has many restrictions.
Mannose group glyceric acid (mannosylglycerate, MG) is a kind of solute of Thermophilic Bacteria body accumulation, and main discovery is present in Thermophilic Bacteria
rhodothermus marinus,
thermus thermophilus, and
rubrobacter xylanophilus,and the ancient bacterium of hyperthermophilic
pyrococcus,
thermococcus,
palaeococcus,
aeropyrumdeng in.Its Main Function is the function with the large biological molecule such as protected protein, nucleic acid, cell membrane, enzyme under high temperature.
Summary of the invention
The object of this invention is to provide the anti-dehydration protection agent of a kind of vegetables nontoxic, safe, easy to use.
Realize a kind of melon and fruit increasing agent of the object of the invention, comprise mannose group glyceric acid, non-ionic surface active agent and water.
The content of described mannose group glyceric acid is 0.05wt% ~ 10wt%.
Described non-ionic surface active agent comprises: sorbitan ester and/or sucrose ester.
The content of described sorbitan ester and/or sucrose ester is 0.01wt% ~ 0.5wt%.
Under a kind of high temperature of the present invention, the beneficial effect of vegetables anti-dehydration protection agent is as follows:
Mannose group glyceric acid is to loss that is thermally-stabilised, that not easily decompose, can stop under high temperature, arid or saline and alkaline condition moisture.
The agent of the vegetables of mannose group glyceric acid anti-dehydration protection is utilized to have following function: the vegetables that mannose group glyceric acid ectogenic process in (1) outside is in high temperature hostile condition improve the adaptability of vegetables high temperature drying, maintain them and keep fresh potentiality.(2) mannose group glyceric acid a kind of compatible material that can retain in plant cell. thus the effect of mannose group glyceric acid can long-term existence, and only little by little disappears in the diluting effect caused because of growth.
Detailed description of the invention
Embodiment 1
Composition and the content of vegetables anti-dehydration protection agent under the high temperature of the present embodiment are as follows:
| Mannose group glyceric acid | 100g |
| Sorbitan ester | 10g |
| Purified water | 10L |
The effect of the vegetables anti-dehydration protection agent of the present embodiment is as follows:
Effect in spinach:
Select the fresh spinach of 1kg, spray the present embodiment anti-dehydration protection agent 20ml, then under summer temperature 32 degrees Celsius, place 4h under the sun.
Experimental result shows that spraying this agent significantly can reduce the dehydration loss that sunlight irradiates lower spinach.Naked eyes can watch that control group is surperficial is dry and astringently fading, and embodiment still keeps more sufficient moisture, comparatively stands upright in blade face.
Embodiment 2
Protectant composition of the present embodiment and content as follows:
| Mannose group glyceric acid | 20g |
| Sucrose ester | 0.2g |
| Purified water | 1000ml |
The effect of the vegetables anti-dehydration protection agent of the present embodiment is as follows:
Effect in pea sprouting:
Get 2kg pea sprouting, spray the present embodiment anti-dehydration protection agent 50ml, then under summer temperature 33 degrees Celsius, place 6h under the sun.
Experimental result shows that spraying this agent significantly can reduce the dehydration loss that sunlight irradiates lower pea seedlings.Naked eyes can watch control group significantly many dehydrations, and bean seedlings are dry and astringent is fading, and embodiment still keeps more sufficient moisture, comparatively stands upright in blade face.
Embodiment 3
Protectant composition of the present embodiment and content as follows:
| Mannose group glyceric acid | 5g |
| Sucrose ester | 0.1g |
| Purified water | 1000ml |
Effect in romaine lettuce:
Get 1kg romaine lettuce, spray the present embodiment anti-dehydration protection agent 20ml, then under summer temperature 35 degrees Celsius, place 8h under the sun.
The effect of the vegetables anti-dehydration protection agent of the present embodiment is as follows:
Realize result and show at high temperature to be exposed to the sun 8 hours, romaine lettuce moisture runs off in a large number, after spraying this protective agent, significantly can reduce the water loss of romaine lettuce.
The preparation method of anti-dehydration protection agent of the present invention is as follows:
By mannose group glyceric acid (0.05wt% ~ 10wt%), sorbitan ester (0.01wt% ~ 0.5wt%) or sucrose ester (0.01wt% ~ 0.5wt%), be dissolved in the purified water of sterilizing, be settled to 1000ml.
The agent of vegetables of the present invention anti-dehydration protection is very easy to use, with spray form atomized spray to vegetable waste surface, can be used for the various vegetables classes such as spinach, romaine lettuce, bean sprouts, three-coloured amaranth, lettuce and cucumber, tomato, sponge gourd.
