Influence of drying temperature on anthocyanin and moisture contents in purple waxy corn kernel using a tunnel dryer
The effect of drying temperature on total anthocyanin and moisture contents in purple waxy corn kernel was investigated by using a tunnel dryer. The amount of anthocyanin and moisture content were studied with the relatively low drying temperature of 60–80 °C under controlling air velocity at 1.5 m/...
