The black(Purpl) colour extracted from natural black soyabean is safe andnonpoisonous. The pigment of black soya bean has been examined in relation to the pH value,temPerature exposure, food additives. metal ion and oxidant.

黑大豆皮中提取的天然黑大豆黑(紫)色素是一种安全、无毒的食用色素。本文研究了黑大豆色素最稳定的pH值范围、高温加热、光照时色素的变化,以及食品添加剂、金属离,、氧化剂等常见共存物质对色素稳定性的影响。

The difference between the total antioxidant capacities of the extract of black soybeans seed coat and that of soybeans seed coat was studied. And the data show that the extract of black soybeans seed coat had higher total antioxidant capacity than that of soybeans. And the seed coat of black soybean may be the chief carrier of the specific functional components of black soybean. Using total antioxidant activity as a dependent variable, we also found out the optimum extraction conditions with the response surface...

The difference between the total antioxidant capacities of the extract of black soybeans seed coat and that of soybeans seed coat was studied. And the data show that the extract of black soybeans seed coat had higher total antioxidant capacity than that of soybeans. And the seed coat of black soybean may be the chief carrier of the specific functional components of black soybean. Using total antioxidant activity as a dependent variable, we also found out the optimum extraction conditions with the response surface analysis method. That is using 60% ethanol-water which pH was 1.0 as solvent and 80℃ as the extract temperature when the extract time, grain size, the ratio of the material and the solvent was fixed.

对比了黑大豆1号种皮提取物与黄大豆皮提取物的总抗氧化能力值,发现黑大豆皮提取物的总抗氧化能力与黄大豆皮提取物的存在显著差异,前者明显比后者强。进而以总抗氧化能力为指标,采用响应面分析法对黑大豆皮中抗氧化物质的提取进行了优化,在豆皮粒度为60目,料液比为1:30,提取时间为2小时的固定条件下,得到的优化条件为:提取剂为pH 1.0的60%乙醇溶液,提取温度为80。

The technology for extracting anthocyanins of black soybean seed coat was optimized by quadric regression orthogonal rotary tests. The results showed that the optimum extraction parameters were as follows: temperature 60℃, time 1 h, ethanol concentration 60%, the ratio of black soybean seed coat mass to ethanol volume 1∶40. It also showed that the most significant (P<0.01) correlations existed between total antioxidant capacity and anthocyanins contents. Moreover, the scavenging free radical capacity of anthocyanins...

The technology for extracting anthocyanins of black soybean seed coat was optimized by quadric regression orthogonal rotary tests. The results showed that the optimum extraction parameters were as follows: temperature 60℃, time 1 h, ethanol concentration 60%, the ratio of black soybean seed coat mass to ethanol volume 1∶40. It also showed that the most significant (P<0.01) correlations existed between total antioxidant capacity and anthocyanins contents. Moreover, the scavenging free radical capacity of anthocyanins in black soybean seed coat to OH·, O-_2· and DPPH· was 1.6 times, 2.2 times and 1.4 times as large as that of Vitamin C, respectively.

黑大豆皮为材料,采用二次回归正交旋转组合设计对其花色苷的提取工艺进行了优化研究。结果表明,最佳提取参数为温度60℃、时间1h、乙醇浓度60%、料液比1∶40。对黑大豆种皮花色苷含量与总抗氧化能力之间的相关性分析表明,二者之间存在极显著的线性关系(P<0.01),且黑大豆种皮花色苷提取物表现出较强的清除OH·、O-2·及有机自由基DPPH·的体外抗氧化作用,其清除能力是维生素C的1.6倍、2.2倍、1.4倍。
