Effects of Blanching and Natural Convection Solar Drying on Quality Characteristics of Red Pepper (Capsicum annuum L.)

Figure 3

Moisture content of pepper during drying in open sun and in solar dryer. Drying was stopped when moisture content reduced to 5%. UBOS: unblanched open-sun drying; UBSC: unblanched solar collector drying; BWOS: blanched in plain water open-sun drying; BSOS: blanched in 2% NaCl solution open-sun drying; BWSC: blanched in plain water solar collector drying; BSSC: blanched in 2% NaCl solution solar collector drying.
