Carotenoid stability and quantity of different sweet potato flesh colour over postharvest storage time

Sweetpotato(Impomeabatatas) or locally known as ‘keledek’in Malaysia, is one of the popularcrops grown by small farmers for the fresh market. Sweet potato is a rich crop with carbohydrates, carotenoidsand pro-Vitamin A.Carotenoids are antioxidants with pharmaceutical potential and have attract...
