Short Communication Antibacterial property of Hylocereus polyrhizus and Hylocereus undatus peel extracts
Food-borne diseases have always been a major concern to the consumers, food safety authorities and food industries. Hylocereus spp or Pitaya peels are normally treated as wastes and will be discarded during processing. In this study, the antibacterial activity of ethanol, chloroform and hexane extracts from Hylocereus polyrhizus (red flesh pitaya) and Hylocereus undatus (white flesh pitaya) pee...
متن کاملQUALITY OF PITAYA FRUIT (Hylocereus undatus) AS INFLUENCED BY STORAGE TEMPERATURE AND PACKAGING SERGIO
Pitaya (Hylocereus undatus) is a non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage (CHIEN et al., 2007). As a new crop, there have been limited studies focused on extending the postharvest quality of pitaya fruit. The main postharvest problems of pitaya fruit are mechanical injury, chilling injury, decay, and water loss (NERD et...
متن کاملPhysico-chemical properties of spray-dried red pitaya (Hylocereus polyrhizus) peel powder during storage
The physico-chemical properties of spray-dried pitaya peel powders kept at accelerated (45 ± 2°C) and room temperature (28 ± 2°C) for 14 weeks and 6 months, respectively were evaluated. Changes in physico-chemical properties of the peel powder were used as indicators of stability, while changes of the betacyanin pigment retention was used to calculate the shelf-life of the powder. Storage tempe...
متن کاملThe Effect of Hylocereus polyrhizus and Hylocereus undatus on Physicochemical, Proteolysis, and Antioxidant Activity in Yogurt
Yogurt is a coagulated milk product obtained from the lactic acid fermentation by the action of Lactobacillus bulgaricus and Streptococcus thermophilus. The additions of fruits into milk may enhance the taste and the therapeutical values of milk products. However fruits also may change the fermentation behaviour. In this present study, the changes in physicochemical, the peptide concentration, ...
متن کاملChemical composition and in vitro evaluation of the cytotoxic and antioxidant activities of supercritical carbon dioxide extracts of pitaya (dragon fruit) peel
BACKGROUND Hylocereus polyrhizus and Hylocereus undatus are two varieties of the commonly called pitaya fruits, and pitaya fruits have gained popularity in many countries all over the world. However, studies on chemical composition and the nutritional quality of pitaya flesh peel are limited. RESULTS Extracts of pitaya (H. polyrhizus and H. undatus) peel were extracted by supercritical carbon...
