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 (31.2g.100g, on average), proteins (18.9g.100g, on average), dietary fiber (35.3g.100g, on average), vitamin E (8,203.6μg.100g, 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±1.08eq.catequina/gsample). In conclusion, Brazilian chia seeds showed high concentrations of lipids, proteins, total dietary fiber, minerals and vitamin E.
本研究调查并比较了在马托格罗索州（MT）和南里奥格兰德州（RS）种植的巴西奇亚籽中常量营养素、水分、灰分、膳食纤维、脂肪酸、矿物质、类胡萝卜素、维生素、黄酮类化合物、酚类化合物、抗氧化活性、植酸和单宁的含量及浓度。研究发现其脂质（平均31.2g/100g）、蛋白质（平均18.9g/100g）、膳食纤维（平均35.3g/100g）、维生素E（平均8,203.6μg/100g）含量较高。两个地区奇亚籽中总酚类化合物和植酸的含量相似。在南里奥格兰德州种植的奇亚籽比在马托格罗索州种植的奇亚籽具有更高的抗氧化活性，且马托格罗索州种植的奇亚籽中单宁浓度更高（19.08±1.08eq.儿茶素/克样品）。总之，巴西奇亚籽中脂质、蛋白质、总膳食纤维、矿物质和维生素E含量较高。
