Abstract
Increasing health consciousness among the consumers has raised the demand for customized meat products. Enrichment of chicken meat with dietary fiber is the focus of this study. A composite millet-based flour is employed as the source of dietary fiber that aids in enhancing the printability of chicken meat. Chicken meat and composite flour were taken in the ratio of 2:1 (w/w), and the optimized conditions for printing were established to be with a nozzle movement speed of 500 mm/min using a 0.82 mm diameter nozzle resulting in an extrusion rate of 4.40 mm3/s employing motor speed of 360 rpm and 5 bar extrusion pressure. The optimized 3D-printed sample was found to have a dietary fiber content of 5.36 ± 0.19 g/100 g that contributes to more than 10% of the RDA. Thus, this study demonstrates the 3D printing of meat-based material supply with enriched dietary fiber providing insights for the development of novel customized meat products with enhanced nutritional composition.
