中文摘要: |
花旗松素具有降血压、抗菌消炎、抗氧化、抑制肿瘤细胞生长等多种生物活性,已经被认定为
新资源食品。为研究花旗松素在乳制品中的抗氧化活性,对不同加工处理下干酪中的花旗松素抗氧化活性
变化进行测定,并分析了干酪加工处理因素之间的相互作用,结果表明:在干酪加工过程中,凝乳酶添加量
对花旗松素的DPPH 清除能力及Cu2+ 还原能力都没有影响,而随着温度、凝乳酸度(pH)及CaCl2 添加量
的不同,花旗松素在干酪中的抗氧化能力均有显著变化,其中温度与CaCl2 添加量,温度与pH 对花旗松素
抗氧化能力变化有相互作用,而pH 及CaCl2 添加量对花旗松素抗氧化能力变化相互间没有影响。 |
英文摘要: |
Taxifolin is a kind of flavanonol,also known as taxifolin. Because of its strong biological function and
health care ability,it is considered novel food( NF) by the European Food Safety Authority( EFSA). To verify the
effect of various components and processing on the antioxidant activity of citicin in dairy products,the antioxidant
properties of taxifolin in low-fat cheese were evaluated and anythsised through response surface. The results showed
that there were no significances in the amount of rennet for antioxidant properties of taxifolin between DPPH free
radical-scavenging activity and cupric-reducing antioxidant capacity,and there were significant in the pH,the
curd temperature and amount of CaCl2 of low-fat cheese for antioxidant properties of taxifolin. Moreover,there were
interaction between the curd temperature and amount of CaCl2,the pH and the curd temperature. |
