Variability in spectrophotometric pyruvate analyses for predicting onion pungency and nutraceutical value
(2017-06)
Onion pyruvate concentration is used as a predictor of flavor intensity and nutraceutical value. The protocol of Schwimmer and Weston (SW) (1961) is the most widespread methodology for estimating onion pyruvate. Anthon and ...
