Abstract
Providing a case study of general applicability in all world’s semi-arid regions where the plant is increasingly harvested, we describe the use and outcomes of solar air heating and ventilation coupled to a conventional kiln to dehydrate Opuntia ficus-indica cladodes. For the first time, the dried cladodes and the ground dehydrated ‘Nopal’ cladodes retain their natural green-yellow color. New applications to functionalize foodstuff and to formulate nutraceutical, personal care and cosmetic products of even higher efficacy and broader scope are anticipated.
