Preparation of novel nano–based films impregnated by potassium permanganate as ethylene scavengers: An optimization study

Potassium permanganate (KMnO4) is a dominant ethylene (C2H4)-scavenger extensively used in fresh horticultural commodities, mainly in climacteric fruit, to prolong their shelf life. This material has been traditionally utilized as a C2H4-permeable sachet for inclusion into packages of produces. New...
