花生蔓水提物抗氧化性及饮品配方研究

摘要

Content and antioxidant activity, Arachis hypogaea L. vine aqueous extracts (AHVAE) were ob-tained,and then mixed to health drink. Results showed that the contents of total sugar, soluble polysaccharide and flavonoids were respectively about(15.04±0.91)%,(5.79±0.51)%, and(2.03±0.36)%in AHVAE. The OH and DPPH free radical could be scavenged about(90.51±2.94)%and(80.75±3.05)%, when the AHVAE concentration was of 50 mg/mL. Based on results of the orthogonal test, the optimal Arachis hypogaea L. vine health drink was obtained when the formulation involved AHVAE 4.00 g/100 mL, sugar 6.00 g/100 mL, honey 2.40 g/100 mL, lemon acid 0.40 g/100 mL, mint essence 0.10 g/100 mL and composite stabilizer 0.15 g/100 mL (CM-Na∶xanthan gum∶pectin=5∶2∶3). The drinks obtained have strong oxidation resistance, good taste, deployment of simple and feasible method suitable for industrial production.%研究花生蔓水提物的主要成分、含量及抗氧化性，并创制花生蔓保健饮品。试验结果表明，花生蔓水提物中总糖、可溶性多糖、黄酮类化合物含量分别为（15.04±0.91）%、（5.79±0.51）%、（2.03±0.36）%。花生蔓水提物抗氧化作用较强，当添加量为50 mg/mL时，对羟基OH自由基和DPPH自由基的清除率可达（90.51±2.94）%和（80.75±3.05）%。正交试验结果表明，花生蔓饮品的最优配方为花生蔓水提物4.00 g/100 mL、蔗糖6.00 g/100 mL、蜂蜜2.40 g/100 mL、柠檬酸0.40 g/100 mL、薄荷香精0.10 g/100 mL、复合稳定剂0.15 g/100 mL（羧甲基纤维素钠∶黄原胶∶果胶=5∶2∶3，质量比）。获得的饮品抗氧化性强、口感良好，调配方法简单可行，适宜进行工业化生产。
