Quality Characteristics of ‘Dongchul’ Persimmon (Diospyros kaki Thunb.) Fruit Grown in Gangwondo, Korea

Abstract

-Persimmon has long been established as one of the major fruits in Korea. The southern parts of Korea were traditionally the pocket areas for good persimmon production; however, rising temperatures have gradually rendered the southern regions unsuitable for successful harvest. Ecology of fruit growing areas affects the productivity of various types of crops, including fruit trees such as persimmon. The quality characteristics of the fruit of persimmon cv. Dongchul grown in Gangwondo, which lies in the northern part of South Korea, were investigated. Different physicochemical, nutritional, and antioxidant properties of fruit were evaluated to assess the locational effect on the quality of persimmon fruits grown in Gangwondo. The results of this study showed that persimmon cv. Dongchul grown in Gangwondo maintains many of the physicochemical (4.33% crude protein and 4.32% crude fiber), nutritional (total mineral content: 461.51 and vitamin C content: 15.28 ㎎/100 g), and antioxidant properties (polyphenol content: 633.1 ㎎ gallic acid equivalent/100 g) those are found in other three commercial cultivars 'Daebong', 'Kyengsan Bansi', and 'Sangju Doongsi' grown in Korea. Overall results of this study imply that 'Dongchul' cultivar of persimmon could commercially be grown in Kangwondo, Korea.

Nutritional and functional characteristics of ripe persimmon (Diospyros kaki L.) fruit

“…Sharma (2015) [24] revealed a value of 6.69 and 6.50 mg/100 g for total phenols in fully ripened Hachiya fruits with and without peel, respectively. On the other hand, Kim et al (2016) [31] revealed 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity of 75.97, 70.12, 71.77, and 72.00 per cent in Dongchul, Daebong, Kyengsan Bans, and Sangju Doongsi, cultivar of persimmon, respectively. In Karaj 12 cultivar of persimmon, a value of 92.00 per cent was noticed for antioxidant activity by Naser et al (2018) [23] .…”

A survey of viruses and viroids in astringent persimmon (Diospyros kakiThunb.) and the development of a one-step multiplex reverse transcription-polymerase chain reaction assay for the identification of pathogens

“…Changes in the climatic conditions of the orchard cultivation area affect not only the growth of the fruit tree but also the quality of the fruit, harvest time, and fruit storage. Therefore, several studies have been conducted to cope with climate change, leading to the successful development of varieties suitable for high-temperature, such as 'Sanggamdongsi' (Kim et al 2016). Furthermore, climate change also imposes serious threats regarding the increased incidence of diseases and pests.…”
