NHJEM, non-heating juice of Elaeagnus multiflora; NHVEM, non-heating vinegar of Elaeagnus multiflora; HJEM, heating juice of Elaeagnus multiflora ; and HVEM, heating vinegar of Elaeagnus multiflora.
All data are presented as the mean±SD of triplicate determinations.
Means with different lowercase letters (a-c) indicate significant differences of juices and vinegars by Tukey’s multiple range test (p<0.05).
ND, not detected.
