Effect of soaking and heating stimulation on the formation of isothiocyanates in Eruca sativa Mill. seeds and sprouts

Wang Q., . and Li X., . and Wang P., . and Gu Z., . and Wang S., . and Yang R., . Effect of soaking and heating stimulation on the formation of isothiocyanates in Eruca sativa Mill. seeds and sprouts. pp. 795-802. ISSN 22317546

The present work investigated the effects of soaking followed by heating on the metabolism of glucosinolates (GLs) in rocket seeds and sprouts. Soaking for 1 h increased myrosinases (MYR) activity of seeds. Heating at 70C for 10 min after soaking resulted in the highest isothiocyanates (ITCs) formation in seeds. Both immerse-heating and steam-heating decreased the total GLs content in seeds and 2-day old sprouts. However steam-heating showed minor effect on total GLs content when compared with immerse-heating. Both methods showed a decreased MYR activity in seeds and sprouts. Nevertheless heating had a positive impact on ITCs formation. Under immerse-heating ITCs formation was the highest in seeds and sprouts at 70C heating. However under steam-heating ITCs formation in seeds and sprouts was higher at 70 and 60C respectively. The results indicated that steam-heating treatment was effective for improving ITCs formation in rocket seeds and 2-day old sprouts.

Abstract

The present work investigated the effects of soaking followed by heating on the metabolism of glucosinolates (GLs) in rocket seeds and sprouts. Soaking for 1 h increased myrosinases (MYR) activity of seeds. Heating at 70C for 10 min after soaking resulted in the highest isothiocyanates (ITCs) formation in seeds. Both immerse-heating and steam-heating decreased the total GLs content in seeds and 2-day old sprouts. However steam-heating showed minor effect on total GLs content when compared with immerse-heating. Both methods showed a decreased MYR activity in seeds and sprouts. Nevertheless heating had a positive impact on ITCs formation. Under immerse-heating ITCs formation was the highest in seeds and sprouts at 70C heating. However under steam-heating ITCs formation in seeds and sprouts was higher at 70 and 60C respectively. The results indicated that steam-heating treatment was effective for improving ITCs formation in rocket seeds and 2-day old sprouts.
