Carrot is a popular vegetable consumed by people of all age groups and is used in various food products because of its high nutritional content, especially vitamin A.
In the present study, colorful fresh carrot juices of 12 carrot varieties were investigated for in vitro antidiabetic, anti-aging, and anti-obesity activities with antioxidant potential by ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and FRAP (ferric reducing ability of plasma) assays. The studied juices were also compared for physicochemical characteristics: titratable acidity, pH, pectin content, total soluble solids, dry mass, ash, viscosity, turbidity, osmolality, and color. The results of the study showed that normal purple carrot juice exhibited the best activities in all biological and antioxidant tests, except for anti-α-glucosidase activity. Normal purple carrot juice also had the highest total mineral content with elevated results for titratable acidity, pH, total soluble solids, dry mass, ash, viscosity, and osmolality.
Purple carrot juices demonstrated elevated health-promoting activities and could be used in blended beverage recipes to attract children's attention. The results of sensorial characteristics (appearance, color, and taste) of juices, however, showed that people are more familiar with orange carrot products. © 2022 Society of Chemical Industry.
胡萝卜是一种深受各年龄段人群喜爱的蔬菜，因其具有较高的营养价值，尤其是维生素 A，常被用于各种食品中。
本研究采用 ABTS（2,2'-联氮-双-（3-乙基苯并噻唑啉-6-磺酸））和 FRAP（血浆还原能力）测定法，对 12 种不同品种的彩色新鲜胡萝卜汁的体外降血糖、抗衰老和抗肥胖活性及抗氧化潜力进行了研究。同时对所研究的果汁进行了理化特性比较：可滴定酸度、pH 值、果胶含量、总可溶性固形物、干物质、灰分、粘度、浊度、渗透压和颜色。研究结果表明，在所有的生物和抗氧化测试中，除了抗α-葡萄糖苷酶活性外，普通紫色胡萝卜汁表现出最佳的活性。普通紫色胡萝卜汁还具有最高的总矿物质含量，其可滴定酸度、pH 值、总可溶性固形物、干物质、灰分、粘度和渗透压都有所提高。
紫色胡萝卜汁具有较高的促进健康的活性，可用于混合饮料配方中，以吸引儿童的注意。然而，关于果汁感官特征（外观、颜色和味道）的结果表明，人们更熟悉橙色胡萝卜产品。 © 2022 英国化学学会。
