Abstract:
Butterfly pea flower have great sensory attraction, but they have not yet been used widely in Vietnam. Extracts of butterfly pea flowers can be used conveniently as a natural blue colorant for food products. In this study, the identification of anthocyanin compounds in butterfly pea flowers was performed by UPLC coupled with a UV and Mass spectrometer instrument. Positive and negative ion electrospray MS/MS chromatograms and spectra of the anthocyanin compounds were determined. By analyzing the chromatograms and spectra for each ion, five anthocyanins were identified in the butterfly pea flowe

Abstract:
‘Mencía’/‘Jaen’ it’s an important red grape variety, exclusive of the Iberian Peninsula, used in wine production namely in Bierzo D.O. and Dão D.O., respectively. This work evaluates the effect of the two different “terroirs” on the phenolic composition and chromatic characteristics of ‘Mencía’/‘Jaen’ monovarietal wines produced at an industrial scale in the same vintage. Using Principal Component Analysis (PCA), Partial Least Squares-Discrimination Analysis (PLS-DA), and Orthogonal PLS-DA (OPLS-DA) it was found that peonidin-3-coumaroylglucoside, petunidin-3-glucoside, malvidin-3-coumaroylglu

Abstract:
Organic fouling in the nanofiltration (NF) process, which is a non-thermal technology to recover active components, is a critical problem limiting its applications. This study seeks to identify the anthocyanins on the NF membrane and explore their fouling mechanisms during concentration of blueberry extracts. Seven kinds of monomeric anthocyanins in foulants—delphinidin-3-O-galactoside, delphinidin-3-O-glucoside, delphinidin-3-O-arabinoside, cyanidin-3-O-galactoside, petunidin-3-O-galactoside, peonidin-3-O-glucoside, and malvidin-3-O-glucoside—were identified.

Abstract:
Composition and degradation of anthocyanins in blue and purple grain wheat during bread production were investigated using the HPLC-MS/MS method. The most abundant anthocyanins were delphinidin-3-rutinoside (blue grain wheat), cyanidin-3-glucoside and peonidin-3-glucoside (purple grain wheat). Peonidin-3-glucoside was also the most stable during grain treatment while delphinidin-3-glucoside had the greatest loss. Both blue and purple grain anthocyanins decreased significantly during bread production to 41.81% and 70.10% after baking, respectively, and to 24.21% and 60.00% after short-term stor

Abstract:
Exudates released from germinating seeds and roots of a black-seeded bean (Phaseolus vulgaris cv. Midnight Black Turtle Soup) induce an antigenic change in the lipopolysaccharide (LPS) of Rhizobium etli CE3. By spectroscopic analyses and chromatographic comparisons with derived standards, the chemical structures of the aglycone portions of the major inducing molecules from seed exudate were deduced, and they were identified as delphinidin, cyanidin, petunidin, and malvidin. These anthocyanidins were present in seed exudate mainly as glycosides, the chief inducer being delphinidin 3-glucoside.

Abstract:
Manufacturing beer with a high biological value requires identifying new methods for increasing the health-enhancing compounds level. The aim of this study was to increase the biological value of beer by adding antioxidant-rich eggplant (Solanum melongena L.) peel extract (EPE). The total phenolic content (TPC), total flavonoid content (TFC), and total monomeric anthocyanin content (TMA) were determined. Moreover, the antioxidant activity was evaluated by different radical scavenging assays. The addition of different levels of EPE resulted in a significant increase of TPC and TFC of beer sampl

Common cyclamen (Cyclamen pururascens Mill.) is a very interesting species not only for various breeding programs but also as an ornamental plant. The plants possess interesting floral and foliage characteristics, nice fragrances, and a very useful flavonol profile. The last is very important from the point of view of protecting against diseases and physiological disorders. Twenty-two different genotypes originating from different regions in Slovenia were analyzed in detail, based on their floral and foliage characteristics.

Abstract:
Fruit color of eggplants is one of the most important traits. In the fruit peel several anthocyanins were identified. It was shown that in fruits of Japanese accessions the basic an anthocyanin was delphinidin-3-(p-coumaroyl rutinoside)-5-glucoside (nasunin), while other accessions contained tulipanin (delphinidin-3-O-rutinoside). The breeding lines for hydroponic small-size cultivation that was selected by researchers from VNISSOK contained 0,021-0,2l7 grams of anthocyanin per kilogram.
