| 摘 要： | 为了开发功能性食用色素新资源,以酿酒剩余皮渣为原料,采用水浸提-大孔吸附树脂分离纯化甜樱桃红色素,并从还原能力、抗脂质过氧化和抑制邻苯三酚自氧化3个方面研究了甜樱桃红色素的体外抗氧化活性。结果表明,采用大孔吸附树脂可以有效分离纯化甜樱桃皮渣中的红色素,甜樱桃红色素具有较强的还原能力,并可有效抑制亚油酸的过氧化和邻苯三酚自氧化,且抑制效果与浓度密切相关。在试验浓度范围内,其对亚油酸过氧化和邻苯三酚自氧化的最大抑制率分别可达到99．53％和99．11％。因此,甜樱桃红色素是一种具有良好抗氧化活性的功能性天然食用色素。

| Abstract: | In order to find new source of functional edible colorant, a pigment extract rich in anthocyanins and phenolics was obtained from sweet cherry pomace by water extracting and adsorption with resins and its reducing power, antioxidant activity against lipid peroxidation and pyrogallol autoxidation, were investigated. Results indicated that the red pigment could be effectively isolated and purified from sweet cherry pomace with adsorbent resins. The sweet cherry red pigment extract (SCPE) was demonstrated to exhibit strong reducing power, antioxidant activity against lipid peroxidation in a linoleic acid model system and scavenging capacities towards superoxide anion radicals generated by pyrogallol autoxidation. Furthermore, the antioxidant activity was correlated with the concentration of the sweet cherry red pigment extract, showing a strong dose-dependent pattern. In the test, concentration range from 0.01 to 5.0 mg/mL, the maximum inhibitition percentage against linoleic acid peroxidation was 99.53% after 8 day's incubation, and the maximum scavenging percentage to superoxide anion radicals generated by pyrogallol autoxidation reached to 99.11%. The results suggested that the sweet cherry red pigment extract may be a natural, edible colorant with excellent antioxidant activities and health benefits and seems applicable in both health food and medicine. |
