“…In soybean sprouts, phenolic and isoflavone compounds under various environmental conditions such as temperature, relative humidity, and irrigation methods have been well investigated (Gan et al 2016;Syukri et al 2018;Silva et al 2020). Among these factors, irrigation condition is one of key factors that can regulate the yield and development of sprouts.…”

Mungbeans (Vigna radiata L.) are one of major legume crops in Asia as major sources of proteins and carbohydrates. Additionally, they provide functional substances such as vitamin and antioxidant compounds when consumed as bean sprouts. In this study, physical traits of mungbean sprouts, such as sprouts yield, thickness and length of hypocotyl, length of epicotyl, number of lateral roots, and length of root depending on four irrigation conditions (irrigation interval: 2 and 4 hours; irrigation time: 2 and 4 minutes) were measured for three cultivars (Dahyeon, Samgang, Sunhwa). In general, the length and thickness of hypocotyl increased gradually until day 3, followed by a decrease on day 4. Lateral roots and the length of root increased during the cultivation period. Sprouts yield was higher under short irrigation time than long irrigation time until day 3. Preferable traits including sprouts yield, the length of hypocotyl, and the thickness of hypocotyl were better under shorter irrigation time conditions (2 minutes). Traits of negative effect for consumers' preference, such as number of lateral roots and length of epicotyl, were lower under longer irrigation interval conditions (4 hours). Samgang had the highest yield of sprouts. However, it also had the highest growth of epicotyl. Although Sunhwa had preferable physical traits of bean sprouts, it had the least yield of sprouts. Overall, Dahyeon cultivated under 4 hours (irrigation interval) & 2 minutes (irrigation time) condition had the most preferable traits for producing mungbean sprouts. This study provides information about irrigation conditions affecting quality-related traits to produce mungbean sprouts.

“…On the other hand, the CO 2 production rate of the DGJ treatment before GPP was stable for the first 24 hours, after that increased gradually to 6 mmol kg Ϫ1 h Ϫ1 in 80 hours and remained approximately constant until the end of the experiment. In our previous report, in normal germination process, CO 2 production rapidly increased during GPP and kept constant during REP until the end of germination period where glucose (sugar) that derived from RFOs breakdown suggested to be used as a respiratory substrate during GPP and another substrate would be used during REP (Syukri et al, 2018). The suppression of CO 2 production during GPP in germinating soybean seed treated by DGJ before GPP might induce the shifting of the respiratory substrate form sugar to lipid due to sugar starvation (Toole and Toole, 2004).…”

“…Sucrose and RFOs including raffinose, stachyose and verbascose were analyzed using a HPLC system (Ultimate 3000, Thermo Fisher Scientific, Massachusetts, USA) equipped with a charged aerosol detector (Syukri et al, 2018). The mobile phase was 0.5 acetic acid in water (solvent A) and acetonitrile (solvent B).…”

“…Our previous research revealed that RFOs content in soybean sprouts is affected by the cultivation temperature and RFOs remained most at 20 due to the smallest total respiratory CO 2 production during cultivation among the tested conditions from 10 to 30 . In addition, the application of a-galactosidase inhibitor suggested to be a promising method to produce soybean sprouts containing high amount of RFOs (Syukri et al, 2018). However, the optimum cultivation method has not been determined yet, especially the role of RFOs in seed germination process should be clarified for optimization.…”

Role of raffinose family oligosaccharides (RFOs), sucrose and lipid in respiration metabolism during soybean seed germination were investigated to determine appropriate method for producing soybean sprouts containing high amount of RFOs. Soybean seed were soaked into 50 mM 1-deoxygalactonojirimycin (DGJ), which is a specific a-galactose inhibitor, for 90 minutes before and after germination preparation phase (GPP). Soybean seed without DGJ treatment was used as control. The growth rate, respiration rate, respiratory quotient, fatty acids and saccharides contents were measured during cultivation at 20. When DGJ was applied before GPP, the degradation of RFOs was significantly reduced, moreover the growth rate and respiration rate were suppressed due to the alternation of respiratory substrate from glucose to lipid in GPP. However, in the DGJ application after GPP, no difference was found from control although RFOs breakdown was functionally inhibited in subsequent radicle elongation phase (REP). These results suggest that RFOs are essential only in GPP as a source of respiratory substrate and lipids play the main role in respiration during REP. Therefore, prevention of RFOs degradation after GPP could be useful to maintain high amount of RFOs in soybean sprouts.
