【摘要】 以早艳桃果实为原料,研究了—100kV/m高压静电场处理对果实失重率、褐变率、腐烂率、果肉硬度、呼吸强度以及相对电导率变化的影响。试验结果表明,高压静电场处理能够有效保持桃果实的采后品质,明显降低早艳桃贮藏过程中的失重率、褐变率和腐烂率,对桃果实的呼吸强度有一定的抑制作用,减缓果实硬度的下降过程,同时使果实果皮相对电导率上升缓慢。更多还原

【Abstract】 The effects of high voltage electrostatic field (HVEF) on the weight-losing rate, browning index, rot rate, pulp firmness, respiratory activity and relative conductance of ’Zaoyan’ peach were studied in this paper. The results showed that HVEF could reduce the weight-losing rate, browning index and rot rate obviously. Meanwhile the respiratory activity and the decrease of pulp hardness of peach were controlled by HVEF. The relative conductance of peach under HVEF increased slowly, which indicated HVEF could control the ripeness and senescence of peach.更多还原
