- Abstract
The aim of this study was to evaluate the induction of mass loss in the post-harvest quality of 'Eragil' peaches after 21 days cold storage at -0.5°C. Was used completely randomized design with five replications of 20 fruits. Were evaluated 4, 5, 6 e 7% of mass loss induced. Woolliness incidence increase with rise in mass loss, two days after storage, but is not affected four days at 20°C. Juiciness, in second day, and ethylene production, in second and fourth days at 20°C, are inversely relationship to mass loss. Fruit firmness were remained and respiratory rate increased with greater mass loss two days at 20°C. 5-6% mass loss provided less evolution of yellow color. Therefore, 'Eragil' peaches are susceptible to wooliness occurrence after 21 days at -0.5°C, be this process reverted at 20°C. The rise in mass loss promotes increase in fruit firmness, woolliness, TSS and respiratory rate, and decrease in juiciness, ethylene production and ACC oxidase enzyme activity.
