조정된 조건하에서 glucose-glycine 혼합수용액을 사용하여 browning을 발달시켰다. Browning pattern은 medium의 pH및 반응물질의 농도에 특히 영향을 받았다. Glucose- glycine수용액을 희석시켜 filter paper disks를 담갔다가 기름으로 튀겼다. 반응물질의 농도는 튀긴 filter Paper dists의 browning pattern에만 영향하고 pH영향은 고온에서 불명확하게 되였다. Glucose-glycine system의 pH 2에서는 무결정형의 갈색 침전물이 생성되었다. 본 model system에서 생성된 갈색 색소를 규명하기 위하여 기기분석을 시도하였다.
Browning pattern was developed in aqueous solutions of glucose/glycine mixture under controlled conditions. Browning pattern was definitely influenced by pH of medium and concentration of reactants. Filter paper disks were immersed in diluted solutions of glucose/glycine system and fried in cooking oil. Concentrations of reactants only affected browning pattern of fried filter paper disks and pH effect was obscured at high temperatures. Amorphous brown precipitate was obtained from the lowest pH medium of glucose/glycine system. An attempt was made to characterize the brown pigment produced in the present model system.
