Abstract

The nasturtium is diverse in bioactive compounds such as carotenoids, anthocyanins, and glucosinolates. Due to these attributes, it is important to apply them to novel foods, such as drinks. The objective of this study was to carry out a sensory evaluation for the viability of the addition of nasturtium extract to a beverage. Solvent extraction was performed at a solute-solvent ratio of 1:10 – 1:15 and ethanol purity of 45%, 70%, or 96%; antioxidant capacity was analyzed by the FRAP method and total phenolic compounds content by the Folin-Ciocalteu method. Additionally, three samples of the beverage that included nasturtium extract (extract content of 1000, 2500, or 5000 mg kg-1) were evaluated through a 5-point hedonic test and a preference test for the attributes of flavor, aroma, consistency, and the product as a whole. The samples with the highest solute-solvent ratio presented the highest antioxidant capacity, while the samples with ethanol purity of 45% and 70% obtained the highest content of total phenolic compounds. The sample with 1000 mg kg-1 of the extract was the best qualified in all the sensory attributes evaluated.

旱金莲(Tropaeolum majus L.)水酒精提取物在热带水果和蔬菜饮料中的应用和感官评价

旱金莲具有多种生物活性化合物，如类胡萝卜素、花青素和硫代葡萄糖苷。由于这些特性，将它们应用于新型食品(如饮料)是很重要的。本研究的目的是对饮料中添加旱金莲提取物的可行性进行感官评估。溶剂萃取:溶剂比为1:10 ~ 1:15，乙醇纯度为45%、70%、96%;用FRAP法测定其抗氧化能力，用Folin-Ciocalteu法测定其总酚类化合物含量。此外，三种含有旱金莲提取物的饮料样品(提取物含量为1000、2500或5000 mg kg-1)通过5点快乐测试和风味、香气、一致性和产品整体属性的偏好测试进行评估。溶溶剂比最高的样品抗氧化能力最强，乙醇纯度为45%和70%的样品总酚类化合物含量最高。以含1000 mg kg-1提取物的样品为最佳。
