Radish anthocyanin extract as a natural red colorant for maraschino cherries

Creator:

Hundskopf, Maria Monica Giusti

Abstract:

Red radish anthocyanin extract (RAE) was investigated for coloring brined cherries as an alternative to FD&C Red No. 40. Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone, partitioned with chloroform, and isolated using C-18 resin. The monomeric anthocyanin content was determined by...

AN ABSTRACT OF THE THESIS OF Maria M6nica Giusti Hundskopf for
Structure and conformation of red radish (Raphanus sativus L.) anthocyanins and their effect on color and pigment stability

Creator:

Giusti Hundskopf, Maria Monica

Abstract:

Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone and chloroform and isolated using C-18 resin. Chemical structure and conformation of major pigments were elucidated by 1-D and 2-D NMR, Mass Spectroscopy, HPLC, and spectral analyses. Two novel di-acylated anthocyanins, pelargonidin 3-0-[2-0-(β-D-glucopyranosyl)-(6-0- trans-p-coumaroyl-...

AN ABSTRACT OF THE THESIS OF Maria Monica Giusti Hundskopf for
Investigation of Optimal Extraction Conditions and Microencapsulation Technique for Stabilizing Anthocyanins and Polyphenols from Fruit Materials

Creator:

Wang, Wenjie

Abstract:

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...
