Abstract

Antioxidant activity of the eucalyptus chemi-mechanical pulp pre-impregnated residue(PR)recognized as waste was studied,and its application prospect in food field was explored.The effects of pre-impregnation conditions(NaOH dosage,temperature and pulp concen-tration)on the PR antioxidant activity and yield were investigated.The difference in the PR chemical structure at various NaOH dosage was studied.The conformational relationship between the PR composition structure and the antioxidant activity was established.The thermal sta-bility,antioxidant activity after high-temperature treatment and cytotoxicity were also used as the evaluation indexes to evaluate the applica-tion performance of PR in the food field.The results showed that the NaOH dosage was the main factor affecting the antioxidant activity and yield of the PR,and the less the NaOH dosage,the lower the yield and the stronger the antioxidant activity of PR.PR fabricated at NaOH dosage of 0(R0)had the best antioxidant activity with highest DPPH free radical scavenging rate of 82.63％.It was also found that R0 had good thermal stability,and could maintain 84％of the initial level after 1 h of thermal treatment at 200 ℃.Moreover,PR had no cytotoxicity to HepG2 cells at a concentration of 100 μg/mL,which met the basic requirements for food applications.The quinone-type conjugate struc-ture was the main reason for strong antioxidant activity of PR.When the NaOH dosage was at a high level(30 kg/t),the content of quinone of PR decreased significantly,and thus led to a decreased antioxidant activity.
