Abstract: Winter jujube fruit was used as material to study the effect of different high\|voltage static electric fields （HVEF） （20，60，100 kV·m-1） treatment for 40 min on respiratory intensity， ethylene release rate， malondialdehyde （MDA） and vitamin C contents， fruit firmness， fruit water content and fruit rot rate. The results showed that HVEF had an obvious inhibition effect on respiration of winter jujube fruit， inhibiting the release of ethylene and MDA content， increasing fruit firmness， Vc content and fruit water content， reducing the incidence of fruit decay and delay the ripening process of winter jujube fruit. Under the same storage situation， 100 kV·m-1 HVEF showed better preservation effect on winter jujube than others treatments.
