Nada El Darra

Associate Professor


I obtained my BSc in Life and Earth Sciences from Saint-Joseph University, Lebanon in 2007. I earned my M.Sc. in Food chemistry with honors from Saint-Joseph University, Lebanon in 2009. Then worked as a Quality manager at Conserves Modernes Chtaura_Lebanon. In 2013, I obtained a certificate entitled “ISO 22000:2005” Food safety management System Lead Auditor from RABQSA. I was subsequently awarded a scholarship to pursue my PhD under a joint program between Saint-Joseph University and University of Technology of Compiègne_France. I obtained in 2013 a PhD in Food chemistry from Saint-Joseph University and a PhD in Industrial Process Engineering and Sustainable Development from University of Technology of Compiègne_France. After completing my PhD, i worked in 2014 as a Quality manager at Abido Spices_Neemeh_Lebanon. I have a number of publications in peer-reviewed journals. In 2014, I was appointed as an Assistant Professor at the Nutrition & Dietetics department, Faculty of Health sciences, at Beirut Arab University. In 2017, I was appointed as a coordinator for the Msc program in Food Safety & Analysis. In 2018, i got promoted to Associate Professor at the Nutrition & Dietetics department.

Teaching

At BAU, I taught undergradute courses: Research Techniques, Food safety & Hygiene, Food Technology, Food service management, Food chemistry, Food additives, Food laws & regulations, Principles of food safety, Biochemistry. I taught as well postgradute courses: Food safety management system, Food laws and regulations, food chemistry and food manufacturing. My general teaching philosophy is based on the student-based learning theory that gets the student involved in all the different aspects of course delivery. My teaching style is hybrid and student-centered. It involves interactive lectures, group discussions,  case-studies, assignments, hand-on experiments and field visits. I incorporate several innovative learning methods in my lectures, such as the TBL (team based learning), as a structured form of small-group learning that emphasizes student preparation out of class and application of knowledge in class. I am incorporating the blended learning techniques in some of my courses.

Research Interests

I am interested in two main research axis: Food technology and Food Safety.

My main research projects in food technology consist of elucidating the role of different emerging techniques in extracting bioactive compounds mainly polyphenols from Food and Food wastes in order to valorize them. I investigated different extraction techniques (Ultrasound, microwave assisted extraction, pulsed electric field, thermal treatment and infrared) for their effects on recycling the polyphenols of fruit and fruit pomace. The assessment of the biological properties (antiradical, antimicrobial, hypoglycemic and cytotoxicity) of the polyphenols extracted was performed as well.

Whereas, my main research projects in Food safety concern developing sensitive detection methods to detect food adulteration.
