Objective:
Objective 1: Utilization of peanuts and peanut processing waste materials, to characterize their functional attributes and the impact on animal and human health for broader commercial market utilization of peanuts and peanut by-products.
Objective 2, Applications of metabolomic and flavoromic approaches to the improvement of peanut quality.
Approach:
The USA peanut industry generates $4.4 billion annually. The value at the farm level is over $1 billion, with approximately 7,500 farms or 1.5 million acres, within 15 states, producing nearly six billion pounds of peanuts in the shell. The peanut industry is composed of producers, shellers, and food processors. The private sector relies on the USDA-ARS to increase and expand markets through continual improvement of peanuts and peanut products across all segments of the industry, from farm to processors and consumers. At present, only two public research programs are dedicated to improving the value of the crop by enhancing flavor, nutrition, and post-harvest processing using modern food science technology. Objective 1: Utilization of peanuts and peanut processing waste materials, to characterize their functional attributes and the impact on animal and human health for broader commercial market utilization of peanuts and peanut biproducts. Peanuts with skins intact will be fed to poultry and the effects on egg and meat quality will be determined. Peanut skins will be added to the rations for pigs to determine the optimum for high quality meat. Peanuts skins will be fed to lactating sows to determine health effects. A human cell line and mice will be exposed to peanut skin extracts to determine hepatoprotective effects. The effectiveness of peanut shells to produce biochar for further processing into biographite will be evaluated. The goal is to create new markets for peanuts and the processing biproducts. Objective 2: Applications of metabolomic and flavoromic approaches to the improvement of peanut quality. Peanuts from field studies evaluating drought resistance and enhanced flavor will be evaluated using advanced metabolomic and descriptive sensory methods with a goal to find peanut cultivars that can adapt to the changing environment and cultivars that have the highest flavor impact for the food market. This project includes stakeholder involvement which is important to this research and helpful in gauging progress via informal discussions throughout the year as well as annual liaison meetings. These meetings and regular interaction with our stakeholders foster transparency, advance industry collaboration, strengthen support for extramural funding, and ensure that our research focus is aligned with industry needs and ultimately providing timely solutions.
