Postharvest behavior of fruit Xoconostle Ulapa (Opuntia oligacantha Först CF) effect of cutting and maturity index

Abstract

We studied the postharvest behavior of fruits of xoconostle Ulapa (Opuntia oligacantha C.F. Först), the effect of cutting and maturity indices under conditions of room temperature and refrigerated storage at 5 ° C. Eight treatments were evaluated; index 1 +5 ° C + Court good index 1 +5 ° C + Court bad, index 2 +5 ° C + cut good, index 2 +5 ° C + cut bad, index 1 + 20 ° good C + Court, Index 1 +20 ° C + Court bad, index 2 + 20 ° C + cut good and index 2 + 20 ° C + cut bad. The variables evaluated were: weight loss, total soluble solids, titratable acidity, total sugars and reducing sugars. For statistical analysis we used the SAS statistical package, completely randomized design, and analysis of variance and multiple comparison test of Tukey at a level of P ≤ 0.05.La greater weight loss was observed in the fruits xoconostle stored at room temperature, with maturity index 2 and with bad cut. At the end of the storage period the highest value in the potential hydrogen and total soluble solids was observed in fruits harvested at maturity indices 2, green changing bad cut and stored at room temperature, however the highest acidity content titratable presented him with the fruits of maturity index Xoconostle 1 bad cut and stored at 5 ° C. The lowest weight loss was observed in the fruits of maturity index Xoconostle with two good cut and stored at 5 ± 1 ° C, decreasing up to 50% compared to the fruits stored at ambient conditions xoconostle.
