【摘要】 本文采用 DPPH 分光光度法,研究了硅藻土的铁离子含量和啤酒 pH 值在过滤阶段对啤酒抗氧化力的影响。结果表明硅藻土的质量和添加量对啤酒的抗氧化能力产生明显影响,其中铁离子含量高、硅藻土添加量大、pH 值低均能降低啤酒的抗氧化力,加速啤酒老化。更多还原

【Abstract】 The effects of iron level in diatomite and pH value of beer on antioxidative activity of beer is studied in this paper by DPPH-spectroscopy.As a result,the quality and additive quantity of diatomite and property of beer take important roles in antioxidative activity,viz,the antioxidative activity of beer is reduced with the condition of high iron level,or/and high additive quantity of diatomite,or/and low pH value.更多还原
