Comparative Studies on the Quality and Lycopene Content of Pomelo (Citrus grandis Osbeck) Cultivars

Abstract

Three cultivars of pomelo “Guanximiyou” (GX) and its variants “Hongroumiyou” (HR) and “Sanhongmiyou” (SH) were selected as experimental materials to evaluate the quality and edible value of the fruit. In this study, the fruit quality and lycopene contents were investigated. The results show that among the 3 cultivars used, the contents of soluble solids, vitamin C, and total phenol in the juice sac of SH were the highest, followed by HR and GX. SH has the largest fruit shape index, soluble sugar content: GX > HR > SH, and titratable acid content: GX < HR < SH. From our findings, the content of lycopene was the highest in SH, followed by HR and GX. SH has the greatest potential for production due to its appreciable content of lycopene and fruit quality.

Fruit Physiology and Sugar-Acid Profile of 24 Pomelo (Citrus grandis (L.) Osbeck) Cultivars Grown in Subtropical Region of China

“…It is believed that the content of soluble sugars accumulated in pomelo fruits from different producing areas is different [42,43]. Regional and climatic conditions have effects on sugar and acid levels in fruits [44][45][46].…”

Effect of an exogenous strigolactone GR24 on the antioxidant capacity and quality deterioration in postharvest sweet orange fruit stored at ambient temperature

“…Citrus fruit is sought after worldwide due to its attractive color, sweet and sour taste, and crispy juicy and rich nutrients like sugars, organic acids, vitamins, phenolics, flavonoids, and carotenoids (Rapisarda et al ., 2008; Yang et al ., 2020; Mou et al ., 2021), most of which are natural antioxidants. In China, more than 95% of citrus fruits are produced for fresh fruit market.…”
