Study on Antioxidant Activity of Aqueous Extracts from Scum of Mixed Juice

Abstract:

The scum of mixed juice is a by-product in sugarcane factory, which used up-floating method for mixed juice clarification. The scum is of great research and utilization value due to its rich organic non-sugar compounds such as proteins, lipids and polyphenols. Studies on the free radical scavenging capacity and reducing power of water extraction sample (A) and macroporous resin purified sample (B) from mixed juice scum were investigated, comparing with Vc. It was showed that the antioxidant activity of macroporous resin purified sample (B) was much stronger than that of water extraction sample (A) and Vc in , and system. For example, the scavenging capacity of sample B on was 11 times than that of Vc and 1450 times of sample A. In addition, the free radical scavenging activity of sample A and B was dependent on the sample concentration. Results in this study indicated that scum of mixed juice may be a promising natural antioxidant, which can be used as additives in food industry or feed industry.
