AB Opuntia species exhibit beneficial properties when used to treat chronic diseases, particularlyobesity, diabetes, cardiovascular disease, and cancer; however, the presence of spines and glochidsin the species’ skin that easily stick into consumers’ fingers has limited their consumption. For thisstudy, white and orange Opuntia ficus-indica fruits from the Canary Islands (Spain) were minimallyprocessed, packed in a passive atmosphere, and stored at 7 ◦C. The effects of peeling (by hand or withan electric peeler) and two micro-perforated films (90PPlus and 180PPlus) were evaluated. Changesin the quality parameters, gas composition, bioactive compounds, sensory features, and microbialsafety of fresh-cut prickly pears were examined during 10 days of cold storage. Both varieties,hand-peeled and electrically peeled, were microbiologically safe (aerobic mesophiles < 7 log(CFU/gfresh weight)) and retained suitable nutritional quality after 8 days of storage. The yield was greaterwhen fruits were electrically peeled than hand-peeled (70.7% vs. 44.0% and 66.5% vs. 40.8% for whiteand orange fruits, respectively). The concentrations of oxygen and carbon dioxide were above 15%and below 7.5%, respectively, in all the treatments over the shelf life. TSS decreased during storageindependently of variety, peeling method, or film. Fructose was the most abundant sugar, followedby glucose and sucrose. The electric peeling machine improved not only the edible part of the fruitbut also the contents of bioactive compounds, such as ascorbic acid and phenolic compounds.
