Solar air drying for innovative Opuntia ficus-indica cladode dehydration
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.
Crop Ecology, Cultivation and Uses of Cactus Pear
Cactus crops are gaining increasing interest across the globe, in particular cactus pear (Opuntia ficus− indica), because of its unique characteristics which provide resilience to the above mentioned harsh conditions. Cactus pear is able to grow on land where no other crops are able to grow; it can be used to restore degraded land and in many countries, such as Ethiopia, it is the only crop that can be relied on when everything else fails. The crop originates in Mexico – still the largest producing and consuming country in the world – but other countries, including Morocco, Ethiopia, South Africa, Kenya, India and Pakistan, are increasing their production and use.
