The effect of boiling, germination and roasting on bioactive properties, phenolic compounds, fatty acids and minerals of chia seed (Salvia hispanica L.) and oils

Abstract

The protein amounts of chia seeds were determined between 27.56% (control) and 28.37% (boiled). Total phenolic and antioxidant activity values of chia seeds treated by several applications changed between 237.70 mgGAE/100g (germinated) and 535 mgGAE/100g (roasted) to 15.27 mmol/kg (roasted) and 15.50 mmol/kg (germinated), respectively. While (+)-catechin amounts of seeds are determined between 15.47 (control) and 60.95 mg/100g (roasted), rutintrihydrate contents of seed extracts were identified between 3.98 mg/100g (control) and 24.92 mg/100g(roasted). While linolenic acid values of oils vary between 62.89% (germinated) and 66.76% (rpasted), linoleic acid amounts of oil samples were identified between 18.55% (control) and 21.04% (roasted). While P contents of chia seeds change between 6103.58 mg/kg(boiled) and 7253.45 mg/kg (control), K amounts of seeds varied between 2534.48 mg/kg (germinated) and 5351.58 mg/kg(roasted). In general, it was observed that the mineral content of boiled chia seeds was low compared to the control and other treated seeds.
