Corn-Based Extruded Snacks Supplemented with Bilberry Pomace Powder: Physical, Chemical, Functional, and Sensory Properties
Source abstract
Abstract
Corn-based extruded snacks are tasty and very popular food products; however, they have high starch and oil and low bioactive content. The aim of the present study was to improve the functional value of corn-based extruded snacks by enrichment with bilberry pomace powder (BPP). Proximate composition, total phenolic content, antioxidant activity, physicochemical properties, including color and texture properties, titratable acidity, expansion ratio, bulk density, water absorption, and water solubility index were evaluated in snacks supplemented with BPP at 2%, 4%, and 6% addition levels compared with the control. The results showed that protein, fiber, and ash content increased with increasing addition levels of BPP. The fiber content increased in the extruded products by about 2.7 times at the 6% BPP addition level compared to the control. The addition of 4% and 6% BPP did not worsen the expansion ratio and hardness of the snacks but significantly decreased their cohesiveness, gumminess, resilience, chewiness, and fracturability. Total phenolic content increased by about 54%, 86%, and 118% for the 2%, 4%, and 6% addition levels, respectively, compared to the control. Based on the results, enrichment with 6% BPP produced a new healthy and attractive snack, which could be recommended for commercial production.
