Oral Presentation:  Chemical structure elucidation of novel pigments produced from thermal stress of hydroxyphenyl pyranoanthocyanins 

Poster Presentation: Diverse Color performance of hydroxyphenyl pyranoanthocyanins across pH  

Awards: Received Groupe Polyphenols Junior Grant and placed 1^st in the division for her poster. Congratulations Danielle!!!

Congratulations to Lu for successfully defending her master’s thesis “Efficient Formation and Color Evaluation of Pyranoanthocyanins Derived from Agro-industrial Byproducts”. Later, we had a lab lunch to celebrate!

Xinyue, Lu and Carlos did a great job at presenting a part of their respective researches in the poster competition

The title for her presentation was “Influence of Chemical Structure on the Color, Molar Absorptivity, and Stability of Naturally Derived Pyranoanthocyanin Pigments”

Congratulations to Dr. Ellia La on her successful dissertation defense. Her dissertation is “Modulating Photochromism of Acylated Anthocyanins by Ultraviolet-Visible Excitation and Acylation Patterns for the Expansion of Color Diversification”

Congratulations to current members (Gonzalo, Danielle, Monica) and lab alumni (Carla, Fei, Pu, Kai, Yucheng, Sydney) on publishing ” THE AMAZING COLORS OF PERUVIAN BIODIVERSITY: SELECT PERUVIAN PLANTS FOR USE AS FOOD COLORANTS” in Anales Cientificos.

Lu’s oral presentation “Formation efficiency and color performance of pyranoanthocyanins derived from anthocyanins and 3-deoxyanthocyanins” won 1^st prize in IFT Food Chemistry Division.

Erica’s oral presentation “Characteristics of American, Bodinier, and Purple Beautyberry as potential novel sources of natural colorants” won 3^rd prize in IFT Fruit and Vegetable Products Division.

Ellia presented “Photoisomerizing structurally diverse acylated cyanidins” at IUPAC Photochemistry Conference in Amsterdam.

Danielle placed first as a member of OSU college bowl team at IFT.

Gonzalo presented “High yields production of novel anthocyanins-derived pigments using 4-vinyphenol as a cofactor” in IFT Food Chemistry Division.

Congratulations to Erica for successfully defending her master’s thesis “Characterization and quantification of anthocyanins and other phenolics in the fruits of Beautyberry species”. We had a lab lunch to celebrate!

Ellia and Monica recently published “Ultraviolet–Visible Excitation of cis- and trans-p-Coumaric Acylated Delphinidins and Their Resulting Photochromic Characteristics” on ACS Food Science and Technology! They found that visible energy induced greater trans-to-cis isomerization, and cis-Dp showed greater color intensity and stability at pH 1 and a greener hue than trans-Dp at pH 8. Great job!

In March 2022, Danielle received a grant from The Ohio State University College of Food, Agriculture, and Environmental Sciences Internal Grant Program for her project titled ” Expanding the color palette of pyranoanthocyanins, naturally-derived food pigments, by evaulating the influence of structural variations on color expression and stability”.

Ellia was selected for an oral presentation at IUPAC Photochemistry Conference in Amsterdam, Netherlands!

Lu was selected as a finalist for the Food Chemistry Division and Erica was selected as a finalist in the Fruit and Vegetables Division at IFT 2022!

The GALA award recognizes exceptional leadership by graduate students as leaders at Ohio State. Only 3 students were chosen from all of Ohio State. Congrats Ellia!

Congratulations to Gonzalo for placing 1st in the CFAES Poster Competition in the post-doctoral category and to Thania for placing 3rd in the Undergraduate Category!

Thania, Erica, Danielle, Xinyue, Lu, James, and Ellia (not pictured due to scheduling conflict with Graduate Leadership Award Ceremony) presented at OVIFT on April 12. Thank you for sharing your research with confidence and advocating for the need of phytochemical research!
