Product development involving consumers is important in developing quality attributes. It ensures that the products developed and marketed satisfy the needs and preferences of the consumers which is important in commercialization.

The sweet potato-based tamarind (camarind) and strawberry (camberry) candies have a sweet- sour taste. Specifically, camarind has soft leathery texture and is seedless. Camberry has soft textural moistness.

The quality of camberry was observed to change at three months after processing. For camarind, the quality started to deteriorate at eight months after processing. Camango has the shortest shelf life of two to four weeks after processing.

At a selling price of P18.50/pack and production costs of P13.55/pack and P14.25/pack for camberry and camarind, respectively, estimated report in Returns on Capital Employed (ROCE) of 36.51 % and 29.82% can be derived.
