Research on Extraction of Proanthocyanidin from Peanut Skin by Aspergillus niger Fermentation
The cell wall of peanut skin was destroyed by cellulase enzymolysis from peanut skin fermentation, which was beneficial to extract proanthocyanidin. The extraction conditions of proanthocyanidin from fermented peanut skin were studied according to orthogonal experiment based on single factor experiments. And the optimum conditions were obtained as follows: extraction time 40min, extraction temperature 55°C, Concentrations of ethanol 45%, solid-liquid ratio 1:15. The extraction rate was 16.17 %.
