Abstract：
In previous studies, the Argentinean native plants called Zuccagnia punctata (jarilla, pus pus, lata) and Solanum betaceum (chilto, tree tomato) were reported as new natural sources of antioxidant compounds, mainly chalcones, anthocyanins and rosmarinic acid derivates. The present study deals with the production of antioxidant beverages of Z. punctata (Zp) extract and chilto juice with honey as sweetener. A Zp extract and red chilto juice were obtained according to Food Code and characterized. The beverages were formulated by using maltodextrin (MD) with two dextrose equivalents (DE), 10 and 15, and then spray-dried at an inlet air temperature of 130 °C. The physicochemical, microscopical, phytochemical and functional characteristics of the powders were surveyed. The experiments carried out showed good physical properties for both formulations showing high water solubility with adequate features for handling, transport and storage. The chromatic parameters of both powdered beverages indicate orange-pink tones regardless of the wall material used. The total polyphenol and flavonoid content in the beverages were kept after spray-drying (92 and 100%, respectively). The anthocyanins were less stable under drying conditions (yield 58%). Both powdered beverages showed high scavenger capacity on ABTS•+, HO• and H2O2 (SC50 between 3.29 to 41.05 µg GAE/mL) and were able to inhibit xanthine oxidase (XOD) activity (CI50 between 91.35 and 114.43 µg GAE/mL). The beverages were neither toxic nor mutagenic in the concentration range with biological activity. The results obtained in the present work scientifically support the use of the powdered beverages of Argentinean native plants as antioxidant.
摘要：
在以往的研究中,阿根廷本土植物称为Zuccagniapunctata（jarilla，脓液,lata)和茄子(辣椒，树番茄)被报道为抗氧化剂化合物的新天然来源，主要是查尔酮,花青素和迷迭香酸衍生物。本研究涉及以蜂蜜为甜味剂的Z.punctata（Zp）提取物和辣椒汁的抗氧化饮料的生产。根据食品代码获得Zp提取物和红辣椒汁并进行表征。通过使用麦芽糊精（MD）与两个葡萄糖当量（DE）配制饮料。10和15，然后在130°C的入口空气温度下喷雾干燥。物理化学，显微，调查了粉末的植物化学和功能特性。所进行的实验显示出良好的物理性质，这两种制剂都显示出高水溶性，具有足够的处理特性，运输和储存。无论使用何种墙壁材料，两种粉末饮料的色度参数都表示橙色-粉红色色调。喷雾干燥后保留饮料中的总多酚和类黄酮含量（92％和100％，分别)。花色苷在干燥条件下稳定性较差(产率58%)。两种粉状饮料在ABTS•+上均显示出高清除剂能力，HO•和H2O2（SC50在3.29至41.05µgGAE/mL之间），并且能够抑制黄嘌呤氧化酶（XOD）活性（CI50在91.35至114.43µgGAE/mL之间）。在具有生物活性的浓度范围内，饮料既没有毒性也没有致突变性。在当前工作中获得的结果科学地支持使用阿根廷本地植物的粉末饮料作为抗氧化剂。
