Sažetak

The effect of processing and storage on antioxidant components and their in vitro bioaccessibility in chickpea and amaranth greens mix
prepared with decorticated chickpea (Cicer arietinum) and green leaves of amaranth (Amaranthus caudatus) was investigated in this study.
Food mix was cooked and stored under frozen storage (wet form) or under refrigeration and at room temperature (dehydrated form) and analyzed.
Polyphenol (PP), tannin (TN) and flavonoid (FL) contents of food mix pre- and post- dehydration were ranged from 253-341, 357-364
and 35-48mg/100g dry weight respectively. Higher values were observed for PP and FN in dehydrated mix and for TN, total and β-carotene in
fresh mix. The bioaccessibility of antioxidant components did not change significantly during frozen storage. The dehydrated mix showed higher
reduction in digestibility of PP than fresh sample. Antioxidant components were retained in dehydrated mix. Frozen storage preserved higher
antioxidant components in the chickpea+amaranth mix than storage at higher temperature.
