the purpose of this paper is to study on the proximate composition, mineral and saponin content in white sesame, black sesame, and perilla seed. For this purpose, we have compared six different materials: white-raw-sesame, white-roast-sesame, black-raw-sesame, black-roast-sesame, raw-perilla seed and roast perilla seed, and have come to the following results. The crude fat content was the highest in white-raw-sesame(55.3%). In all the six samples, the crude fat content in raw seeds was all higher than that in roast seeds. The crude protein content was the highest in the roast perilla seed(24.6%), and in the six samples, the crude protein content in roast seeds all higher than that in roast seeds. The total sugar content was found to be the highest in the roast perilla seed(8.29%). The reducing sugar content was higher in raw perilla seed(1.57%) than in other sample materials. The ash content was the highest in black raw-sesame(5.93%), and that percentage rates was the same as that of FAO and of Japan. Minerals like Cd. Mn. Cu. Na. Mg. Pb. and Ca. were found to be contained more in black sesame than in other sample materials. The minerals contained most in white sesame were Zn.(61.6ppm) and Fe(49.4ppm), and K was contained a little more in perilla seed than in the others. The sample materials which contain saponin most were white-roast-sesame(0.34%) and black-roast-sesame(029%).
