Heat stable protein masking solutions

As consumer demand for high-protein snacks, cereals, and meat alternatives continues to grow, extrusion remains a critical processing method — but one that introduces significant flavor challenges. Temperatures of 120–180°C degrade desirable flavors, flash off volatiles, and promote protein-flavor binding, resulting in bitterness, beany or earthy off-notes, and astringency that reduce consumer acceptance. Edlong's proprietary heat-stable masking technology addresses this directly, utilizing molecules known to limit access to bitter receptors and decrease astringency. In a case study with pea protein crisps extruded at ~130°C on a twin-screw extruder (~350 g/L wet density), evaluation one-month post-extrusion showed a significant reduction in bitterness and an increase in butter flavor compared to unflavored controls. This technology can extend beyond protein crisps to extruded cereals, whole grain snacks, shelf-stable protein beverages, and plant-based cheese — any application where high heat or high starch traps and distorts flavor profiles.
