Study on waxy corn hybrids - XVI. Analysis of protein and amylogram on waxy corn (Zea mays L.) hybrids

Abstract

: Protein content of waxy corn hybrids ranged from 9.3 to 17.1%, and amylopectin content ranged from 83.9 to 94.5%. Three waxy corn hybrids including CNU043 showed less than 10 percent in protein content, and seven waxy corn hybrids including CNU052 were higher than 94% at the amylopectin content. At the amylogram test the ranges of the pasting temperature, peak viscosity, hot viscosity, cool viscosity, breakdown, setback, and consistency were 71.6～ 77.5℃, 58～210 RVU, 36.1～114.2 RVU, 47～145 RVU, 21.4～97.8 RVU, -66.4～-9.6 RVU, and 11.1～36.3 RVU, respectively.
