“…In order to maintain postharvest fruit quality under ULO, oxygen concentrations must be kept just above the anaerobic compensation point, when anaerobic respiration begins. This reduces acid or sugar loss during respiration, lowering fruit metabolism (Wendt et al, 2022). Determining the lower oxygen limit tolerated by fruit requires a series of calculations and evaluations, with different methodologies based on ethanol determination, chlorophyll fluorescence, respiratory quotient and CO 2 production (Wendt et al, 2022), as well as variations between the genotype and phenotype of the materials.…”

However, this technique must be thoroughly studied before its use, since tolerance of ULO and high CO 2 varies according to cultivar, storage temperature and storage time (Ceretta et al, 2010).…”

The peach tree (Prunus persica) has a considerable global economic impact because its fruits are consumed worldwide. As climacteric fruits, peaches ripen after harvest and are also highly perishable postharvest. The aim of this study was to investigate alternatives for extending storage time and preventing a decline in quality in peaches using conventional cold storage (CS) compared with controlled atmosphere (CA) and ultralow oxygen (ULO) systems. A completely randomized design was used, with a 3 x 6 factorial scheme (3 storage systems x 6 storage times), thirteen parameters assessed by analysis of variances and significance by Tukey’s test and regression. Total soluble solids (TSS) varied from 12.72 to 16.07ºBrix, titratable acidity (TA) declined during storage and pH varied significantly among the systems used from 40 days of storage onwards. The best TSS/TA ratio was obtained under ULO after 40 days, while firmness and weight loss declined in CA and ULO, contrasting with the brightly colored pulp. Reducing and non-reducing sugars decreased under CA and ULO at 30 and 40 days of storage, whereas phenolic compounds and antioxidant activity remained similar in these systems at 30, 40 and 50 days. Carotenoids remained stable for up to 40 days in ULO.CA and ULO maintained the best physical and chemical quality parameters, both systems being the most recommended. The phytochemical compounds analyzed in this study changed little during storage in the systems analyzed.
