The moistures, colors and flavors of red pepper were analyzed to observe the changes of the qualities of red pepper with various conditions of drying. The moisture was 11.8%, known as optimal condition for storing red pepper, where dried at $50^{\circ}C$ for 36 and 48 hours. The color of red pepper air-dried at 50% for 48 hours was estimated to be the most execllent in comparison of sun drying and air drying. The optimal absorbances of hexnae extract from red pepper were examined. The ratios between the absorbances at 280nm and at the typical wavelengths of caretenoids(430nm, 450nm, 474nm) were from 2.5-3.4 and these wete also confirmed by the sight of the eye. Hexane fraction showed more peaks of flavors than benzene fraction and both of the two were silylated by with BSTFA to analyze the flavors by GC. CG profiles for the compositions of flavors in red perpper are thought to be useful for extimating the quality of favors in red pepper. Eight flavors including benzene dicarbozylic acid, were identified from red pepper and major components of them were oleic palmitic acids. Drying temperatures and times did not have effects on the changes of specific flavor components but did influenced the compositions of them in red pepper.
