Int J Food Sci:新型绿色经济桃果提取物具有有效的抗菌活性

2018-05-02 MedSci MedSci原创

尽管桃子副产品在促进健康的成分中含量很高,但它往往被视为食物废物。其中多酚是具有明显健康益处的生物活性分子。本研究调查了一种环保且具有成本效益的方法,使用GRAS食品添加剂β-环糊精(β-CD)从桃果渣中回收多酚。在质量(抗自由基活性)和数量方面,将相同浓度(10mg/mL,20 mg/mL,30 mg/mL,40 mg/mL和50 mg/mL)的多酚的β-CD辅助提取与常规溶剂(乙醇)提取进行比

尽管桃子副产品在促进健康的成分中含量很高,但它往往被视为食物废物。其中多酚是具有明显健康益处的生物活性分子。本研究调查了一种环保且具有成本效益的方法,使用GRAS食品添加剂β-环糊精(β-CD)从桃果渣中回收多酚。

在质量(抗自由基活性)和数量方面,将相同浓度(10mg/mL,20 mg/mL,30 mg/mL,40 mg/mL和50 mg/mL)的多酚的β-CD辅助提取与常规溶剂(乙醇)提取进行比较。50 mg/mLβ-CD辅助提取显示多酚获取量最大(0.72mg GAE/g DM)和类黄酮(0.35mg儿茶素/g DM)浓度最高,抗自由基活性(6.82%)最大,具有明显的抗菌活性。

综上所述,该研究结果表明,β-CD辅助提取的效果很好,可从桃果渣中回收高质量的多酚,表明β-CD可作为酚提取的绿色替代方法。
