摘要:

以花椒叶与金露梅叶为原料,采用超声波辅助提取联合大孔树脂吸附技术制备花椒叶提取物(ZBE)与金露梅叶提取物(PFE),通过等辐射分析法研究二者的抗氧化协同效应,确定其最佳复配比;采用单因素试验与正交试验确定花椒叶-金露梅叶复合饮料的生产配方与制备工艺。研究结果表明:当ZEB与PFE复配比为3:1(质量比)时,其抗氧化协同效应最强。复合饮料的最佳配方为花椒叶-金露梅叶复配物(3:1)0.1%、木糖醇0.015%、阿斯巴甜8.00%、柠檬酸0.10%、CMC-Na 0.30%、黄原胶0.02%、β-环状糊精0.40%和山梨酸钾0.05%。煮沸灭菌30 min后,饮料的菌落总数、霉菌、酵母菌、大肠杆菌数与食源性致病菌数符合国家标准;总酚的量(TFC)为0.014 1 μmol/g,总黄酮的量(TPC)为0.019 8 μmol/g,6种主要成分儿茶素、阿魏酸、金丝桃苷、芦丁、槲皮苷和阿福豆苷的量分别为(28.76±0.20)、(13.72±0.16)、(65.32±0.55)、(19.85±0.27)、(62.76±0.36)、(16.78±0.22) mg/g;ABTS+·清除能力为(2.09±0.011)μmol/g,三价铁离子还原能力(FRAP)为(1.21±0.003)μmol/g,DPPH·的半数抑制质量浓度(IC50)为(436.48±3.16) mg/L,具有较强的抗氧化活性。化学稳定性试验与保质期的预测及验证试验表明,该饮料在(25±2)℃下保质期可达6个月。

Abstract:

The Zanthoxylum bungeanum leaves extracts(ZBE) and Potentilla fruticosa leaves extracts(PFE) were prepared by ultrasonic assisted extraction and macroporous adsorptive resins, and the optimal mixing ratio was determined by isoradiation analysis. The results showed that the mixture of ZBE and PFE(mass ratio 3:1) exhibited the strongest synergistic antioxidant interaction. The formulation of ZBE and PFE compound beverage was as follows: the mixture of ZBE and PFE(3:1) 0.10%, xylitol 0.015%, aspartame 8.00%, citric acid 0.10%, CMC-Na 0.30%, xanthan gum 0.02%, and β-cyclodextrin 0.40%, 0.05% potassium sorbate. After boiling sterilization for 30 min, the total colonies numbers, mold and yeast numbers, coliform numbers, and foodborne pathogenic numbers of beverage were all meet the national standards, the total phenol content(TPC) was 0.014 1 μmol/g, the total flavonoid content(TFC) was 0.019 8 μmol/g, the content of the six main components catechin, ferulic acid, hypericin, rutin, quercitrin and afzelin were(28.76±0.20), (13.72±0.16), (65.32±0.55), (19.85±0.27), (62.76±0.36), (16.78±0.22) mg/g, the ABTS+· free radical scavenging capability was (2.09±0.011) μmol/g, the FRAP trivalent iron reduction capacity was (1.21±0.003) μmol/g, the mass concentration of the samples required to removing 50% DPPH·(IC50) was (436.48±3.16) mg/L, it exhibited strong antioxidant effects. Furthermore, after chemical stability test and the prediction and verification tests of shelf life, the shelf life at (25±2) ℃ was 6 months.
