dc.description.abstract | Beef processing produces high volumes of protein rich, low value, ‘waste’ co‐products such as offal. Beef improves uptake of low bioavailable non‐haem iron (found in vegetables, fortificants, supplements) and this effect is dubbed the ‘meat‐factor’, although the underlying mechanism is not fully understood. Here, we investigate whether bovine co‐products (kidney, lung, heart) not previously studied share this enhancing potential. This was determined by coupled in vitro digestion of co‐products and subsequent caco‐2 cell ferritin formation (an intracellular iron storage protein). In this study we show that bovine co‐products significantly increase caco‐2 cells’ response to non‐haem iron from infant rice cereal. The presence of these co‐products, (kidney, lung and heart), increased relative uptake (by 207.13%, 171.21%, 265.28%, respectively), to a greater extent than beef (30.23%). Our findings present a novel function for co‐products of beef processing that may have potential as food ingredients to improve non‐haem iron bioavailability, thus adding value. | en |
