Development of novel omega-3 enriched poultry products. New Health recommendations and changes to the Food Standards Code encourage greater dietary intake of omega-3 (w-3) fatty acids. Our core research on modifying fatty acid composition of poultry tissues and preliminary studies with our industry partner's proprietary fishmeal product (PorcOmega) have indicated the feasibility of producing novel meat products and eggs with high w-3 contents, which would qualify to carry a new nutrition label. ....Development of novel omega-3 enriched poultry products. New Health recommendations and changes to the Food Standards Code encourage greater dietary intake of omega-3 (w-3) fatty acids. Our core research on modifying fatty acid composition of poultry tissues and preliminary studies with our industry partner's proprietary fishmeal product (PorcOmega) have indicated the feasibility of producing novel meat products and eggs with high w-3 contents, which would qualify to carry a new nutrition label. We now propose, in collaboration with our industry partner, to assess the viability of producing such products by conducting poultry feeding trials with PorcOmega on a commercial scale and evaluating both the levels of w-3 enrichement of chicken breast, thigh and sausages, shelf-life and consumer acceptability (sensory evaluation) of these products. We expect to establish feeding strategies for adoption by commercial producers of premium poultry and eggs for local or export markets.Read moreRead less
Establishing evidence for the functional properties of a whole grain in weight management. The successful development of functional foods relies on communicating proven effects. This project aims to prove that the food containing the satiety properties of a whole grain (OG) may help in weight management. We will conduct basic research investigating the link between consumption of OG-containing foods and the regulatory mechanisms of satiety, and test whether the satiety properties can be used to ....Establishing evidence for the functional properties of a whole grain in weight management. The successful development of functional foods relies on communicating proven effects. This project aims to prove that the food containing the satiety properties of a whole grain (OG) may help in weight management. We will conduct basic research investigating the link between consumption of OG-containing foods and the regulatory mechanisms of satiety, and test whether the satiety properties can be used to prevent, reduce and correct body weight gain in the early, middle and late stages of obesity. We will then apply this understanding in a human trial of mildly and long term overweight subjects, to aid the formulation of statements on the potential health benefits from consuming OG.Read moreRead less
