The widespread farming of chia seeds in Kenya translates to increased uptake at household level while offering a niche for industrial processing of chia seeds necessitating the need for studies on physical, total phenolic and flavonoid properties of chia seeds grown in Kenya. The physical, total phenolic and flavonoid properties of chia seeds from two chia planning seasons April to August 2019 and September to December 2019 were evaluated. The physical attributes (length, width and thickness) were determined using a digital vernier calliper while proximate components were determined using AOAC standard methods. The Quencher procedure was used to determine the total phenolic and flavonoid contents. Chia seeds revealed a length of 1.82 to 2.32 (mm), a width of 1.15 to 1.31 (mm) and a thickness of 0.77 to 0.88 (mm). The percentage moisture content of chia seeds was 7.23 to 10.67, percentage of crude fat was 31.48 to 42.45, percentage of crude ash was 3.63 to 6.82, and percentage of crude fibre was 30.95 to 38.65 and percentage of crude protein was17.82 to 28.97. The total phenolic content observed for chia seeds was 0.73 to 0.87 mg GAE g<sup>-</sup><sup>1</sup> while total flavonoid content was 0.39 to 0.57 mg GAE g<sup>-</sup><sup>1</sup>. The proximate components of chia seeds varied significantly (p < 0.05) based on the chia planting season while the physical properties, total phenolics and total flavonoid contents did not vary significantly.展开更多
