Chlorophyll, anthocyanins, carotenoids and lycopene are naturally occurring pigments that give fruits and vegetables their characteristic bright colors. Spices though primarily used for flavoring and preserving food also contain these pigments. Owing to the vast array of application, especially, of natural pigments in food, cosmetic, nutraceutical and medicine, several extraction methods have been described including the use of oils as a solvent to recover these bioactive compounds. Our goal is to study the oxidative stability of infused/macerated oils stored over time. Cloves and cinnamon were macerated in olive oil (OO) and njangsa seed oil (NSO) over 7 d at 45-50oC. The contents of chlorophyll a and b, lycopene and carotenoids were determined spectrophotometrically. Higher pigments contents were measured in NSO than OO. All the oils and macerates showed reduced pigments content (45 - 88%) with incubation, indicating increased oxidative degradation and reduction of shelf life. Generally, higher reduction in pigments content were observed in NSO-macerated spices (75 - 83%) compared with their olive oil counterparts due to its high level of unsaturated fatty acids. The results highlighted the need to improve shelf stability of pigments towards various processing and storage conditions to preserve the beneficial properties of oils and macerates.

DSU Summer Research Symposium 2021

Simultaneous Determination of Pigments Content in Oils and Macerates

Welcome to Delaware State University’s Annual Summer Research Symposium, and thank you for attending! Our symposium represents the culmination of students’ summer experiences in research at Delaware State University. This event showcases the work of college students working on faculty-led research projects, as well as middle and high school students experiencing research for the first time working in research groups. Whatever the case, this summer has been a unique experience for the students, and we hope a transformative one. Even for students who are not planning a career in scientific research, their summer experience has given them skills they will draw on for years to come. 
 Please join us on the mainstage and in Gather for the live event, and visit the recorded poster presentations any time.
 The student participants and organizers of the various summer programs at DSU would like to thank all of the research mentors who guided our summer program participants. There were many DSU faculty, graduate students, and other research and program staff who gave their time and energy to help our students have a fun and educational summer experience. Without their generosity and patience these summer programs would not be possible.
 For the research participants, we hope that you will maintain contact with your research mentors and colleagues. Science is a relatively small community made up of disciplinary “neighborhoods”. If you continue to work in a discipline, the other folks in that discipline will be like your neighbors that you run into regularly. Staying in contact with them will help you keep up with the news of the neighborhood, and open doors to educational and career opportunities. Whether you continue in science or take a different career path, for this summer you have been part of the world of research, and you will benefit from that perspective for the rest of your life.

Please register for the DSU Summer Research Symposium 2021 to be able to access the content.  
If you have already registered, please login with the same email you used to registered for the Conference.
