Effect of Drying Whole and Half Chili Pods Using a Solar Dryer with CaCl2 Desiccant on Quality of Powder Chili

Abstract

This study investigated the quality of dried whole and half chili pods’ powder dried with solar drying combined with CaCl2 desiccant compared with natural convection solar drying to produce the final chili powder product. Besides the sensory analysis, the quality parameters such as beta-carotene, moisture, vitamin C, and ash content were also observed. The results showed that 57 hours of drying time of whole and half chili pods using solar drying can reach moisture content below 5%. Beta-carotene, ash, and vitamin C contents of the whole chili were higher than those of half chili pods’ dried pepper powder; they were 20.38 ± 0.22 mg / 100 g , 5.81 ± 0.15 % , and 23.99 ± 0.57 mg / 100 g , respectively. This study can guide the red chili drying process based on the quality of the dried chili powder.

Response Surface Optimization of Solar Drying Conditions and the Effect on the Quality Attributes and Drying Characteristics of Qula Casein

“…Therefore, the surface becomes unsaturated, and the drying rate had a decreasing trend [ 45 ]. Our findings are consistent with the study that a solar dryer from solar energy systems is more promising than natural convection solar drying methods due to hygienic characteristics and short drying times [ 56 ].…”
