The elucidation of the structure of the red pigments of the black
raspberries. Monger variety, was achieved. The components of the
pigment of the berries were (a) cyanidin-3-glucoside, (b) cyanidin-3,
5-diglucoside, (c) cyanidin-3-diglucoside and (d) cyanidin-3-rhamnoglucosido-
5-glucoside. The elucidation was carried out after isolation,
purification, concentration and chromatographic separation of...
The retention of pigments in processed raspberries is
a function of the process method and conditions of subsequent
storage. The presence of sucrose and the nature of the
headspace gas also influences the retention of the pigment.
The effect of some of the above variables on the pigments was
A method for separation and characterization of individual anthocyanins was
developed. High Performance Liquid Chromatography (HPLC) with a polymer based
reversed-phase column was used to separate the pigments while on-line Photodiode
Array Detection (PDA) was employed to record the UV and Visible spectrum of the
individual peaks. Spectral information obtained...
The objectives of this research were to investigate the optimal conditions for anthocyanins extraction from different anthocyanin rich fruit and to develop microencapsulation formulation for improving stability of anthocyanin extracts. In the extraction optimization study, two extraction methods, "conventional solvent extraction (CE)" and "ultrasound-assisted extraction (UE)" for three different anthocyanin-rich...
The scarcity of wireless spectrum resources and the overwhelming demand for wireless broadband resources have prompted industry, government agencies and academia within the wireless communities to develop and come up with effective solutions that can make additional spectrum available for broadband data. As part of these ongoing efforts, cognitive radio...
