In many instances, when designing and building equipment for food applications, there exists a gap between efficiency and food safety. Machines are efficient, but the safety of the food that it processes is not considered. These machines are deemed inappropriate once introduced to potential users. The study aims to assess the quality and safety of a developed concentrated solar thermal processing (CSTP) system for cashew kernel roasting for local processors in Cagayan de Oro, Philippines. Microbiological and physico-chemical analyses were conducted and evaluated using the Philippine National Standards (PNS) as reference for specifications. Moisture, color, and microbial content are well within the standards of a maximum of 5%, white to brown, and negative to E. coli and Salmonella, respectively. Breakage during processing from measuring size per kilogram was also very minimal at below 5%. These results show that a localized, cheaper, and readily fabricated CSTP system can produce roasted cashew kernels within PNS and can be adopted for use for a more efficient and quality and safety-compliant processing.
