Abstract: In this paper,blue bilberry,medlar and chrysanthemum extract were used as the main raw materials,with white granulated sugar and maltodextrin as plasticizers,to prepare a blueberry,medlar and chrysanthemum compound tablet candy with a health care function and unique taste.The anti-oxidation test was carried out on the pressed candy.Based on a single factor investigation,the optimal mixture extraction process was determined by an orthogonal experimental design,and the anti-oxidation index of the mixture was determined to determine its reducing ability,DPPH free radical,ABTS free radical and hydroxyl radical scavenging ability.The best formula is：blue hazelnut,medlar-chrysanthemum extract mix ratio of 3∶2∶1;the prescription 50%;white sugar 35%;maltodextrin 15%,stevioside 2.0%,citric acid 1.0%,sodium citrate 0.4%,vitamin C 1.0%,taurine 0.5%,β-carotene 0.05%,vitamin B₁ 0.05%;adding magnesium stearate 0.2%,mixing time 10 min at 12 r/min.The results of the antioxidant activity showed that at 1.0 mg/mL,the reduction of sassafras and Lycium-Chrysanthemum compressed candy was 0.357%;the DPPH free radical scavenging rate was 49.13%,and the ABTS free radical scavenging rate was 99.09%.The base clearance was 87.42%.The results showed that the blue hazelnut and medlar-chrysanthemum composite tableting candy had better antioxidant activity.
