Effects of Hot Water Treatment on LOX and PLD Activity in Cucumber

doi:10.7668/hbnxb.2009.06.020

Abstract

Abstract: In order to study changes of PLD and LOX activity under chilling injury temperature(2℃ ),after being treated with hot water for 30 min at 38,45 and 52℃,cucumbers were stored at 2℃for 15 d.Electrolyte leakage,MDA concent,LOX and PLD activity were determined.The result showed that hot water treatment resulted in lower cell membrane permeability,reduced MDA accumulation,maintained low level of PLD and LOX activity,and 45℃for 30 min was the optimum one among three hot water treatments.

Key words: Heat treatment, Cucumber, PLD activity, LOX activity
