目前的研究集中在胡萝卜叶片的增值,DaucuscarotaL.因为它们含有大量的抗坏血酸(AA),酚类化合物,和相关的抗氧化活性。在这项研究中,不同的干燥技术(冷冻,真空,微波辅助红外,烤箱)和不同的储存条件(室温和冰箱)进行了研究。新鲜的AA含量,干,和储存的胡萝卜叶样品进行色谱测定。此外,TPA(总酚含量)分析,TAC(总抗氧化能力),总叶绿素,类胡萝卜素,和颜色进行了。此外,分析了新鲜的叶子,以将其结果与处理或储存的样品的相应值进行比较。TPA,TAC,AA,总叶绿素,储存在冰箱中的样品的类胡萝卜素值为889±63毫克/100克d.b.,504毫克/100克d.b.,269A.A./100gd.b.,253毫克/100克d.b.,和2497毫克/100克d.b.,分别,而在室温下干燥的样品的值为620±35mg/100gd.b.,303±15毫克/100克d.b.,110±21毫克A.A./100克d.b.,44±3毫克/100克d.b.,641±16毫克/100克d.b.,分别。因此,新鲜胡萝卜叶比许多叶类蔬菜甚至它自己的家庭有更高的维生素C含量,欧芹.在室温和冰箱中储存7天的新鲜样品提供高抗坏血酸保留。具有MWIR组合系统的干叶在生物活性成分方面提供了比其他更好的保护。然而,在40°C下进行OD处理可提供更好的保护,并且在AA含量方面领先一步。
The current study focused on the valorization of carrot leaves, Daucus carota L. because of their high amount of ascorbic acid (AA), phenolic compounds, and the related antioxidant activity. In this study, the changes in carrot leaves caused by different drying techniques (freeze, vacuum, microwave-assisted infrared, oven) and different storage conditions (room temperature and refrigerator) were investigated. AA contents of fresh, dried, and stored carrot leaf samples were chromatographically determined. Additionally, analysis of TPA (total phenolic content), TAC (total antioxidant capacity), total chlorophyll, carotenoid, and color were carried out. Additionally, fresh leaves were analyzed to compare their results with the corresponding values of processed or stored samples. TPA, TAC, AA, total chlorophyll, and carotenoid values of the samples stored in the refrigerator were 889 ± 63 mg/100 g d.b., 504 mg/100 g d.b., 269 A.A./100 g d.b., 253 mg/100 g d.b., and 2497 mg/100 g d.b., respectively, while the values of the samples dried at room temperature 620 ± 35 mg/100 g d.b., 303 ± 15 mg/100 g d.b., 110 ± 21 mg A.A./100 g d.b., 44 ± 3 mg/100 g d.b., 641 ± 16 mg/100 g d.b., respectively. Consequently, fresh carrot leaves have a higher vitamin C content than many leafy vegetables and even its own family, parsley. Fresh samples stored at room temperature and in the refrigerator for 7 days provided high ascorbic acid retention. Dried leaves with the MW + IR combined system provided better protection than others in terms of bioactive components. However, OD treatment at 40°C provided better protection and was one step ahead in terms of AA content.
