| This paper from the "king of vegetables"- green asparagus existing post harvest storage technology condition, and the high voltage electrostatic field on post harvest fruits and vegetables, tomato, apple respiratory climacteric and non climacteric fruit and vegetable green pepper, cucumber preservation mechanism of green asparagus, by exploring the properties change, the high voltage electrostatic a vision of Post harvest Green Asparagus preservation has a certain effect.At the same time, for this idea, the experiment on this paper verified the analysis. The test is the main content of the high voltage electrostatic field of Post harvest Green asparagus spears were placed in the 65 KV, 75 KV, 20 d for treatment, then every 2D to determine the water loss rate, soluble sugar content, VC content, respiration rate, the crude fiber content, chlorophyll content and peroxidase, polyphenol oxidase reaction and physiological characteristics indexes.Finally, the test data collection, statistics and analysis, get the conclusion: Post harvest green asparagus tender stem respiration jump during storage, the sugar and chlorophyll content increase after decreases first, have apparent after cooked. Sensory evaluation, treatment group and the control group the difference effect; But the high voltage electrostatic field treatment after mining green asparagus tender stem, get a delay after ripening degree; Weightlessness rate, VC content, crude fiber content and respiration intensity by corresponding inhibition; For the POD and PPO enzyme activity, high voltage electrostatic field treatment of post harvest green asparagus tender stem activity is always higher than the control group. Therefore, HVEF intensity on the physiological characteristics of Post harvest Green Asparagus have a certain influence. |
