Research Summary:

The use of antioxidants is an effective way to minimize or prevent lipid oxidation in food products, retarding the formation of toxic oxidation products, maintaining nutritional quality and prolong the shelf life of foods.  The exploration of naturally occurring antimicrobials to improve food safety and food preservation receives increasing attention due to consumer awareness of natural food products and a growing concern of microbial resistance toward conventional preservatives.  In view of resistance patterns of pathogenic bacteria against antirmicrobial agents, there is an urgent need for new natural antimicrobial products from plant materials is essential.  Natural antioxidant compounds will be tested against lipid oxidation in meat product.  Natural antimicrobial compounds will be tested against foodborne pathogens to determine antimicrobial activity.  The study will determine their efficacy as future antimicrobial or antioxidant products.  Identification and characterization of antimicrobial and/or antioxidant compounds extracted from specialty crops will be performed.
