Study on Preparation and Antioxidant Properties of Chia Seed Gel
The effects of adding amount of distilled water, gelation temperature, gelation time and salt adding amount on the water retention of chia seed gel were studied by single factor experiment and orthog-onal experiment.At the same time,the scavenging ability of chia seed gel on DPPH and hydroxyl radical was studied.The results showed that the optimal water retention condition of chia seed gel was the weight ratio of chia seed to distilled water is 1∶0.5,the water bath temperature is 33 ℃,the water retention time is 5.5 h,and the measured water retention is 99.70％.The scavenging ability of chia seed gel and chia seed on DPPH is 34％ and 27％,respectively,and the scavenging ability of chia seed gel and chia seed on hydroxyl radical is 40％ and 32％,respectively.The scavenging ability of chia seed gel on DPPH and hydroxyl radical was improved.
