| Abstract:
Leaves of Amaranthus spp., fresh, sun-dried blanched and stored in the refrigerator and freezer were analysed for their total carotenoids and chlorophyll contents over 4 weeks period of storage. Extractable total carotenoids of the fresh vegetables increased with blanching and sun-drying. Slight losses occurred in the blanched vegetables during storage in the refrigerator and freezer but the carotenoid content of the sun-dried materilas was unaffected by storage at room temperature. Extractable chlorophyll was higher in the blanched than in the fresh vegetables. The initial chlorophyll content in the blanched material further decreased during storage in both refrigerator and freezer. Chlorophyll also decreased in sun-dried vegetables throughout the period of storage. Sun-dried and freezer-stored vegetables retained more of the visual and culinary properties than those stored in the refrigerator. | |
