Effect of postharvest spray of apple polyphenols on the quality of fresh-cut red pitaya fruit during shelf life

Application of Gelatin Incorporated with Red Pitaya Peel Methanol Extract as Edible Coating for Quality Enhancement of Crayfish (Procambarus clarkii) during Refrigerated Storage

“…Pitaya, belonging to Cactaceae family, is a native fruit from Mexico and Central and South America [5,6]. Red pitaya peel is considered a waste of the processing and represents 33% of the fruit total weight [7].…”

“…Extracting the active ingredient from the peel can improve the utilization of the peel. Meanwhile, peel extracts are commonly used as biological preservatives in many food processes, especially in the aquatic product, to prolong shelf life including essential oils from tangerine peels and mango peel extracts and polyphenols from apple peels [6,11,12]. Edible coating can be used to protect phenolic compounds from oxidation by external factors such as the presence of light, oxygen, metal ions, pH, and high temperatures [13] and provide fresh food protection to prevent quality loss and weight loss.…”

Constituent diversity of ethanol extracts from pitaya

“…It is a kind of new fruit with beautiful fruit shape, bright color, delicate flavor, unique aroma, and beneficial to human health 10 . Pitaya pulp and pericarp rich in polyphenols are good antioxidants, and dragon skin has inhibitory effect on the growth of melanoma cells 11 . The content of trace elements such as magnesium, 12 manganese, and cobalt in pitaya is also very high, and the amino acids in pitaya seed protein are very complete 13 .…”

Simultaneous analysis of indaziflam and its metabolites in pitaya using dispersive solid phase extraction coupled with liquid chromatography coupled with tandem mass spectrometry

“…It is a well‐known tropical and subtropical fruit with great commercial value owing to its special nutritional and functional compositions . The fruit is rich in betacyanins, glucose, phytoalbumin, polyphenols, organic acids, vitamins, calcium, and soluble dietary fiber . Additionally, it has been reported that betacyanins and polyphenols from the pitaya (especially pitaya peel) have antioxidative activity and may assist in the prevention of chronic diseases, such as cancer, cardiovascular diseases, heart diseases, diabetes, and obesity .…”

“…Pitaya flowers can also be used as food. Currently, pitaya is widely cultivated in tropical and subtropical regions, including Thailand, the Philippines, Vietnam, Malaysia, and southern China . These warm and humid climates provide a favorable environment for continuous weed emergence and vigorous vegetative growth, and frequent rainfall or irrigation and nutrient applications further enhance weed pressure .…”
