Ma. Concepcion C. Lizada

Field of award: Biochemistry

Year awarded: 1986

Division: Chemical Sciences


In recognition of her outstanding leadership and dedication in generating information and technologies towards the reduction of postharvest losses of tropical fruits and vegetables and in developing manpower in this aspect. Dr. Lizada has devised an analytical method used worldwide in the study of development and senescence of plant tissues and deterioration of crops after harvest. She has also developed an ethylene scrubber using clay and rice hull ash as carrier and characterized the postharvest behavior of many tropical fruits which is a necessary step responsible for verifying that that hot water treatment can be used successfully on “carabao” mango to drastically reduce postharvest losses due to decay. Her published work on sulfite-induced lipid peroxidation provides an insight into the possible phytotoxic effects of SO2 which is used as a postharvest fumigant.
