Effect of Quinoa and Amaranth Starches as Fat Replacers on the Technological and Quality of Fresh, Fermented and Emulsion Beef Sausages

Sausages, a global favorite, generated $6 billion in African market revenue in 2018, but their reliance on animal fat poses health risks like diabetes and cardiovascular diseases. This study explores quinoa and amaranth starches as climate-resilient alternatives to corn starch in fresh, fermented, and emulsion sausages. Starch was extracted via wet milling using water, sieving, and centrifugation, while sausages were formulated with fat replacers at 3% and 10% inclusion levels. Technological property analyses included water-holding capacity (WHC), cooking loss, pH, emulsion stability, and 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging activity. Higher fat replacer levels reduced cooking loss, with quinoa starch excelling in fresh sausages and amaranth starch performing best in fermented and emulsion sausages. WHC was superior at 10% inclusion, particularly for fresh and emulsified sausages. Quinoa starch showed strong antioxidant activity at lower levels, while higher inclusions enhanced benefits in emulsion sausages. These starches proved promising alternative fat replacers, offering health and shelf life benefits in sausage formulations.
