Description: 
The minimally processed fruit and vegetable industry showed rapid growth worldwide, primarily due to the increasing consumer need for ready-to-eat fresh products characterized by high nutritional, sensory and healthy value. The postharvest life of peeled cactus pear fruits is relatively short, due to the processing operations that affect fruit integrity and cause metabolic disfunctions, as well as pulp browning, microbial growth, loss of firmness, off-flavor development, and nutraceutical value loss. In this study, we investigated the effects of mucilage-based (OFI) and calcium ascorbate edible coating on minimally processed cactus pear summer-ripening fruit, cold stored under passive atmosphere. The effect of the edible coating on the postharvest life, quality attributes, and nutraceutical value of fruit was evaluated by colors, total soluble solids content, carbohydrates; titratable acidity, ascorbic acid, betalains, DPPH, visual quality, and sensorial analysis. Our data showed a significant effect of mucilage-based and calcium ascorbate-based coating on preserving quality, nutritional value, sensorial parameters, and improving postharvest life of minimally processed cactus pear fruits; OFI had the most effective barrier effect. Furthermore, both coating treatments did not negatively affect the natural taste of minimally processed cactus pear fruits, which is an important aspect regarding the use of edible coatings when taste modification is undesirable.
