【 摘 要 】

This study investigated and compared the occurrence and concentration of macronutrients, moisture, ash, dietary fiber, fatty acids, minerals, carotenoids, vitamins, flavonoids, phenolic compounds, antioxidant activity, phytate and tannin in Brazilian chia seeds grown in the states of Mato Grosso (MT) and Rio Grande do Sul (RS). High concentrations of lipids (31.2 g. 100 g(-1), on average), proteins (18.9 g. 100 g(-1), on average), dietary fiber (35.3 g. 100 g(-1), on average), vitamin E (8,203.6 mu g. 100 g(-1), on average) were observed. Similar values for total phenolic compounds and phytic acid in chia seeds from both regions were observed. Chia grown in RS showed higher antioxidant activity than chia grown in MT, and the tannin concentrations were higher in chia seeds grown in Mato Grosso (19.08-1.08 eq. catequina/g sample). In conclusion, Brazilian chia seeds showed high concentrations of lipids, proteins, total dietary fiber, minerals and vitamin E. (C) 2016 Elsevier Ltd. All rights reserved.
