Product Development Competition • 2017: (In-Progress) IFT Developing Solution for Developing Countries. o Novel and innovative fermented defatted groundnut flour is incorporated into the ramen noodle to provide improved nutrition to those that lacks proper nutrient balanced diet in India. The noodle was designed to improve byproduct utilization in peanut industry while providing lacked nutrition in rural areas where food distribution problem persists. • 2016: Finalist at Dairy Competition o Iced-coffee frozen creamer ‘Java Chill’ – Designed to provide consumers with instant iced coffee beverage simply by adding hot, freshly brewed coffee into the product and shake. It was designed mostly with dairy that also provides 10 g of high quality protein per container. • 2016: 2nd place winner at DDW The Color House Competition o Color changing lava fruit jam filled cookie ‘Truffleappear’ – It is innovative uses of color degradation as fun way to incorporate into baking that also allows for some sense of food safety as color changes to “normal” baked cookie color from green. Innovation also was highlighted by uses of fruit jams instead of boring chocolate chips to create completely new product that allows for more healthy-conscious consumers to indulge guilt-free. • 2015: DDW The Color House Competition o Worked on innovative chia seed based gummy bear that incorporates all natural colorants to excite young consumers • 2012: IFT Product Development Competition o Worked on chocolate covered frozen yogurt by incorporating innovative ingredients such as chia seeds wafer, black-garlic chocolate, and naturally flavored yogurt. Research Experiences Research Assistant in Department of Food Science and Technology, Aug 2014 – Present • Study evaluating the development of improving tilapia diets to enhance long chain n-3 fatty acids and oleic fatty acids while reducing n-6 fatty acids. o Worked on Feed formulation of high quality n-3 and n-9 enriched aquaculture pellet diets using various oil sources including high oleic-sunflower oil, soybean oil, fish oil and algae oil o Maintained the tilapia RAS system and monitored growth and health implication due to the dramatic change in lipid profile o Evaluated the fatty acid profile and muscle characteristics of the fish fillet with n-9 and n-3 enhanced diet using GC/MS-TQ o Analysis of oxidative states and change in fatty acid profile under long term storage using GC/MS, Spectrophometric measurement of peroxide values and HPLC for tocopherol analysis o Sensory evaluation of fish muscle for flavor and aroma differences in enhanced diet using preference taste and texture analysis on baked fish fillet o Analysis of rate of change in fatty acid composition in tilapia fillet due to change in diet with finishing diets over 2 weeks. • Evaluated the kinetics in geosmin and 2-methylisoborneol in tilapia RAS o Trace level analysis of geosmin and MIB in various locations in RAS using GC/MS o Sensory analysis of geosmin and MIB in the water and tilapia fillet in RAS • Evaluation of Antimicrobial Activity of Grapeseed Extracts o Performed Optical density analysis to determine the impact of grapeseed extracts on the growth of various pathogenic bacteria and spoilage yeasts • Mentorship o Mentored undergraduate for the development of MRM method for 3,3-dimethylbutanol using GC/MS-TQ o Mentored various undergraduates through Food Science Club and Graduate School Research Assistant in Department of Food Science and Technology, Jan 2012 – Dec 2013 • Evaluated the presence of natural antimicrobial compounds in various medicinal mushrooms. o Phenolic compounds of ethanolic extractions of medicinal mushrooms were fractionated using HPLC o Antimicrobial activity of phenolic fractions of extracts on L. monocytogenes and Z. bailii were observed. o Microorganisms were tested by looking Bioscreen C as well as disk diffusion assay looking at minimum inhibitory concentrations.
