Resistant starch and polyphenol contents in Camelina sativa L. enriched extruded snack products

Extruded snack products are a popular product type among all consumers’ niches – from infants to elderly, since they are tasty and easy to consume regarding chewing and preparation. However, this is energy dense, nutritionally rather poor product category. Therefore, the aim of this research was to increase nutritional value of the extruded corn-based snacks with defatted Camelina sativa L. cake. Namely, Camelina sativa L. is valued for its oil, rich in omega-3-fatty acids. By-product of oil production is cake, rich in polyphenols, fibre and protein. Around 10 – 14 % of oil resides in the cake and may cause problems during extrusion due to low friction in barrel and fat oxidation. The residual oil was extracted from the cake by supercritical-CO2 extraction and defatted cake was obtained. Defatted Camelina sativa L. cake was added to corn grits in 3, 6 and 9 % d. m., 1 % pectin was added and mixture moisture was set to 15 %. Prepared samples were extruded in laboratory single screw extruder with 4 mm round die, screw with compression ratio of 4:1, at temperature profile: 135/170/170 °C. Obtained extrudates were air-dried and resistant starch content was determined according to AOAC 2002.02 method, starch damage according to AACC 76-31 and polyphenol content by Folin-Ciocalteau. Although extrusion resulted in significant decrease of resistant starch and polyphenol contents, resistant starch and polyphenol contents in extruded samples increased proportionally to addition of defatted Camelina sativa L. cake, while starch damage decreased. Defatted Camelina sativa L. cake was successfully applied in nutritional fortification of extruded snack, maximizing the utilization of the seeds and reducing the environmental impact of oil industry.
