电场技术对于热带水果保鲜机理影响研究

Effect of Electric Field Technology on the Preservation Mechanism of Tropical Fruit

电场技术已在保鲜领域得到验证及应用,但其保鲜机理尚不明确。部分研究认为电场可以抑制果蔬中酶的活性,降低果蔬的呼吸代谢强度,实现果蔬的保鲜,但此结论并未得到有效的验证。前期研究发现,呼吸跃变型水果、非呼吸跃变型水果在同样的电场条件下呼吸代谢规律表现出较明显的差异。果蔬代谢以及表现的形状主要受基因表达影响,本文将围绕电场对于热带水果代谢基因表达的影响,确定电场热带水果保鲜的机理。

Electric field technology has been verified and applied in the field of preservation,but its mechanism is not clear.Some studies suggest that electric field can inhibit the activity of enzymes in fruits and vegetables,reduce the respiratory and metabolic intensity of fruits and vegetables,and realize the preservation of fruits and vegetables,but this conclusion has not been effectively verified.Previous studies have found that the respiratory metabolic patterns of respiratory jump fruits and non-respiratory jump fruits show obvious differences under the same electric field conditions.The metabolism and shape of fruits and vegetables are mainly affected by gene expression.This paper will determine the mechanism of keeping tropical fruits fresh around the influence of electric field on the expression of metabolic genes in tropical fruits.
