Abstract:
... Cyanidin-3-glucoside (C3G), an anthocyanin constituent of fruits and vegetables. It has been proven to possess numerous health benefits with no side effects. However, the poor stability of C3G is an intractable property that limits its application. Hence, the aim of this study is to improve the stability of C3G through the formation of well dispersed nanoparticles. In this study, C3G loaded β-CD-E ...

Abstract:
... Anthocyanins are present in bright colored fruit and vegetables with growing evidence for their health benefits. Several methods exist in the literature to measure the total monomeric anthocyanin content in foods. Although the simplest method uses UV–Vis spectrophotometry, it requires the use of anthocyanin molar absorption coefficients (Ɛ). While commonly reported for some compounds, these values ...

Abstract:
... Flower and fruit color is one of the most important features of horticultural plants. Its formation and regulation are always affected by both internal and external factors. Among these factors, the UDP-glucose: flavonoid 3-O-glucosyltransferase (UFGTs) have a major role in the development and production of flowers and fruits colors. The UFGT enzymes are critical for upholding anthocyanin synthesi ...

Abstract:
... In order to broaden the application of grape skin anthocyanin extract (GSAE) in flour products, the interaction of gliadin (Gli) and GSAE were investigated. Seven anthocyanin components from GSAE were identified by HPLC-MS², which could form complexes with Gli having different binding rates based on UV, FTIR and HPLC analysis. The fluorescence quenching experiment showed that GSAE was capable of e ...

Abstract:
... The bitter and astringent taste of tea and tea extract is still not favored by many consumers, which limits its applications to bakery foods and functional foods. Many bitter and astringent compounds in tea leaves are susceptible, which transform during tea processing or can be modified by food production technologies. Besides, the accumulations of the major bitter and astringent compounds in fres ...
