fast determination of anthocyanins and free pelargonidin in Fruits Fruit juices and Fruit Wines by high performance liquid chromatography using a core shell column
Journal of Separation Science, 2016Co-Authors: Sercan Yildirim, Asim Kadioglu, Aykut Saglam, Ahmet Yasar, Hasan Erdinc SellitepeAbstract:Anthocyanins are water-soluble pigments that are liable for colors ranging from red to blue of most Fruits, vegetables, and flowers. A novel and fast method was developed for the determination of five anthocyanins and free pelargonidin by high-performance liquid chromatography coupled to photodiode array detection. A 10% formic acid and acetonitrile mixture was employed as mobile phase in the gradient elution mode. Mobile phase composition, column temperature, flow rate, injection volume, and column conditioning time were optimized by employing a stepwise strategy. Using a C18 core-shell column (100 × 4.6 mm, 2.7 μm), the separation of six analytes was accomplished in less than 9.5 min with a run-to-run analysis time of 19 min. The developed method was validated with respect to linearity (r > 0.9999), limit of detection, limit of quantification, intra-/interday precision (<2%), accuracy (98.6-104.4%), and specificity. Afterwards, the method was applied to the determination of anthocyanins present in 15 different samples including Fruits, Fruit juices, and Fruit Wines.

comparison of amino acids biogenic amines and ammonium ion of Wines made of different types of Fruits
International Journal of Food Science and Technology, 2017Co-Authors: Xiaoyu Ouyang, Shaoyang Wang, Guanshen Yuan, Yaran Liu, Bolin Zhang, Baoqing ZhuAbstract:Summary Amino acids, biogenic amines and ammonium ion are the primary nitrogen sources in Fruit Wines. Compared to grape Wines, our knowledge to their profile in Wines made of other Fruits is very lack. Fourteen Wines made of nine kinds of Fruits together with seven grape Wines were selected to compare their nitrogen component profile. White grape Wines possessed the highest level of total amino acids, followed by red grape Wines and then the Wines made of the other Fruits. Red grape Wines contained the highest level of biogenic amines, followed by white grape Wines and the Wines made of the other Fruits. Ammonium ion was also found to be higher in the Wines made of grapes. Principal component analysis revealed that the obvious separations existed among the Wines made from different types of Fruits, indicating that these nitrogen compounds could be served as the indicators to differentiate different types of Fruit Wines.

polyphenolic compositions and chromatic characteristics of bog bilberry syrup Wines
Molecules, 2015Co-Authors: Shuxun Liu, Baoqing Zhu, Hangyu Yang, Jiayue Zhang, Bolin ZhangAbstract:Phenolic compounds determine the color quality of Fruit Wines. In this study, the phenolic compound content and composition, color characteristics and changes during 6 months of bottle aging were studied in Wines fermented with bog bilberry syrup under three different pHs. The total anthocyanins and total phenols were around 15.12-16.23 mg/L and 475.82 to 486.50 mg GAE/L in fresh Wines and declined 22%-31% and about 11% in bottle aged Wines, respectively. In fresh Wines, eight anthocyanins, six phenolic aids and 14 flavonols, but no flavon-3-ols were identified; Malvidin-3-O-glucoside, petunidin-3-O-glucoside and delphinium-3-O-glucoside were the predominant pigments; Chlorogentic acid was the most abundant phenolic acid, and quercetin-3-O-galactoside and myricetin-3-O-galactoside accounted for nearly 90% of the total flavonols. During 6 months of bottle storage, the amounts of all the monomeric anthocyanins and phenolic acids were reduced dramatically, while the glycosidyl flavonols remained constant or were less reduced and their corresponding aglycones increased a lot. The effects of aging on blueberry wine color were described as the loss of color intensity with a dramatic change in color hue, from initial red-purple up to final red-brick nuances, while the pH of the fermentation matrix was negatively related to the color stability of aged wine.
