【摘要】 通过采用酶抑制动力学方程的方法,研究了高粱原花青素(SPC)对小曲酒酿造中β-淀粉酶的影响。结果表明,高粱原花青素对β-淀粉酶具有明显的抑制作用。抑制的机理是通过可逆的竞争性抑制来实现的,其抑制常数Ki是1.28 mg/mL。更多还原

【Abstract】 To study the inhibition effect of β-amylase by sorghum procyanidins（SPC）,the inhibition kinetics equation was established to analyze the inhibition type.Results showed that the activity of β-amylase was obviously inhibited by SPC via reversible competitiveness,the constant of inhibition(K_i) was 1.28 mg/mL.更多还原
