Establish of Optimum Cultivation Temperature for the Production of Peanut Sprouts

Abstract

The present study was conducted to development mass production methods for peanut sprouts that is considered as a field of blue ocean among the agricultural products. 'Jopyeong' was the best as a major cultivar for peanut sprouts production. The manual for the production of high-quality peanut sprouts is as following. Germination temperature appropriate for production of high-quality peanut sprouts was 27℃. Peanut sprouts at the growth stage of 8th day, and older plants with advanced growth showed deteriorated merchantable and eating quality. Resveratrol compound was not found in the seeds, but its highest amount was detected from 9-day old sprouts. The best water temperature applicable to high quality peanut sprout production was 25℃. The growth of peanut sprout was inhibited by the high temperatures above 35℃ and low temperatures below 15℃.

Resveratrol, total phenolic and flavonoid contents, and antioxidant potential of seeds and sprouts of Korean peanuts

“…The results showed that peanut cultivars and breeding lines having smaller seed size or rapid growth rate could be economically efficient for getting higher sprout yields. Some of the cultivars and breeding lines had excessive sprout growth on day 8 and 9 which showed deteriorated eating and marketing quality [20].…”

“…Miao et al [12] obtained optimum resveratrol content in the peanut sprouts on day 5. Lee et al [20] found the highest resveratrol content on day 9. Kang et al [23] reported the total polyphenol and antioxidant activities of peanut sprouts on 9 days.…”
