Abstract:
OBJEC TIVE To optimize the simultaneous extraction technology of dietary fiber （DF）and flavonoids from the peel of Prunus armeniaca . METHODS The content of DF was calculated with enzyme-gravimetric method ，and the content of flavonoids was determined by ultraviolet spectrophotometry. The orthogonal design and single factor test were used to optimize the extraction technology ，with the factors of liquid-solid ratio ，pH，papain concentration ，α-amylase concentration ，temperature of enzymatic hydrolysis and time of enzymatic hydrolysis as factors ，using the contents of DF and flavonoids as indexes. RESULTS The optimal extraction technology included the solid-liquid ratio of 1 ∶ 10（g/mL），pH5，0.5％ papain and 0.5％ α-amylase， enzymatic hydrolysis at 50 ℃ for 1 h. After three times of validation ，the average content of DF was 0.801 g/g（RSD＝1.95％）， and the average content of flavonoids was 2.135 mg/g（RSD＝2.44％）. The average comprehensive score was 0.988（RSD＝ 0.81％）. CONCLUSIONS The optimal extraction technology is stable and feasible.
