Phenolic Content and Antioxidant Activity of Cantaloupe (<i>Cucumis melo var. cantalupensis</i>) and Food Application

Abstract

The objectives of this study were to determine phenolic content and antioxidant activity of methanolic extracts from different parts of cantaloupe (skin, seed and flesh), and to evaluate the efficiency of using cantaloupe skin wastes methanolic extracts at concentrations of 200, 400 and 600 ppm, respectively by compared with BHA on oxidative stability of mayonnaise incubated at 40°C to accelerate the oxidation for 60 days. The flesh extract give the highest yield (62.87±2.3 g extract/100 g powder) whilst the lowest yield was obtained from the seed (2.866±0.06 g extract/100 g powder) (p < 0.05). The skin extract showed the highest total phenolic content (8.47±0.21mg GAE/g extract) and total flavonoid content (5.23±1.32 µg RE/g extract) accompanied with best antioxidant activity through antioxidant assay (p < 0.05). For mayonnaise stability show sample treated with CSE at level 400 ppm showed the lowest value for acid value (0.296±0.00 mg KOH/g fat) and peroxide value (6.56±0.07 meq.O2/kg fat) at the end day of storage 60 day. There is no significant between it and BHA at 60 day. Thus, these results suggest that methanolic extracts of skin cantaloupe may serve as a potential source of natural antioxidant for food, nutraceutical application and could be used to retard fat auto-oxidation.

“…Similarly, these values are much higher than the values reported by Preciado-Rangel et al 26 of 4.56-6.48 GAEC100 gG 1 FW, in cantaloupe melon fruits produced using different nutrient solutions (Steiner solution, compost tea, vermicompost tea and vermicompost leachate). Also, the TPC range recorded in this study is larger than the value of 4.32 GAEC100 gG 1 FW published by El-Din Ibrahim and El-Masry 24 for the flesh of cantaloupe extracts.…”

“…The highest amount of total flavonoids, corresponded to 0.09 mg catC100 gG 1 FW, was found in T 4 (VC:RS, ratio 1:4, v:v). The range of values recorded in this study, 0.06-0.09 mg catC100 gG 1 FW for the total flavonoid content, was vastly outweighed by the value of 0.20 mg REC100 gG 1 FW determined by El-Din Ibrahim and El-Masry 24 in the flesh of cantaloupe extracts. The range reported here was also lower than the range of values, 0.74-4.71 mg QECgG 1 DW, reported by Khatana et al 30 in peel extract of different cucurbits.…”

“…Different studies have shown that the total phenolic content, TPC, in the plants is associated with their antioxidant activities, presumably due to their redox properties, which allow them to act as reducing agents, hydrogen donors and singlet oxygen quenchers 24 . The range of values recorded in this study, 12.1-15.3 GAEC100 gG 1 FW for the total phenolics, exceeded the value of 11.45 GAEC100 gG 1 FW determined by Chun et al 25 in fresh fruits of Honeydew melon.…”

A comparative study of bioactive compounds, antioxidant activity and phenolic compounds of melon (Cucumis meloL.) slices dehydrated by oven, microwave and infrared systems

“…Also, p-coumaric acid contents of dehydrated melon samples varied between 0.15 (infrared) and 0.88 mg/100 g (oven) while ferulic acid amounts of dehydrated melon samples change between 0.26 (infrared) and 0.91 mg/100 g (oven). Also, while quercetin amounts of dehydrated melon samples are found between 0.69 (microwave) and 1.21 mg/100 g (infrared), Masry, 2016). In other study, Vella et al (2019) reported that melon peel extract contained 2.45 mg/g gallic acid, 0.08 mg/g chlorogenic acid, 0.06 mg/g rutin, 0.09 mg/g ferulic acid, 0.57 mg/g ellagic acid, 002 mg/g quercetin and 0.32 mg/g isorhamnetin.…”
