摘要: Abstract In the context of side-stream valorization, this study aimed to gain insight into functionalization industrially-generated pumpkin pomace as texturizing ingredient. Given matrix complexity pomace, composed crushed peels, seeds and mesocarp, focused on impact different sample preparation, well mechanical processing, microstructural rheological properties suspensions. Pumpkin suspensions (4% w/w) possessed a solid-like behavior, demonstrating potential for structure build-up. The application heat during preparation (85°C, 30 min) significantly increased storage modulus pomace-derived suspensions, which was found be related an swelling volume suspended particles. Moreover, combination partial pectin removal high pressure homogenization at 80 MPa led improved network formation, obvious from modulus. These results are highly useful scientific basis exploring with minimal processing or conventional methods (e.g. by treatment).
