Identification of New Betalains in Separated Betacyanin and Betaxanthin Fractions from Ulluco (Ullucus tuberosus Caldas) by HPLC-DAD-ESI-MS

Mosquera, Natalia Cejudo Bastante, María Jesús Heredia Mira, Francisco José

An improved methodology of achieving an accurate separation of pure fractions of betacyanins and betaxanthins from Ullucus tuberosus Caldas has been carried out. For that purpose, an in-depth chemical identification of each betalain fraction using HPLC-DAD-ESI-MS was developed. This procedure allowed to evaluate the fractionation efficiency and...

Potential use of new Colombian sources of betalains. Color stability of ulluco (Ullucus tuberosus) extracts under different pH and thermal conditions

Cejudo Bastante, María Jesús Hurtado, Nelson Mosquera, Natalia

The potential use of ulluco (Ullucus tuberosus) extracts to be added as natural colorant to other products has been studied. The stability of ulluco extracts at different pHs and temperatures over time has been thoroughly conducted. Our attention was focused on the tristimulus colorimetry, differential colorimetry and betalains related to...
