Biofunctional gelatin-based films incorporated with food grade phycocyanin extracted from the Saharian cyanobacterium Arthrospira sp.
Abstract
International audience ; Biofunctional films based on bovine gelatin (G) incorporated with a food grade phycocyanin (PC) extract at various concentrations (1.25%, 2.5%, 6.25% and 12.5%; w/w) were developed. PC incorporation maintained the original solubility of gelatin (control) film, while, when added at 6.25% and 12.5% (w/w), PC decreased the L* and increased b*, Delta E and the opacity values of the films, which enhances their light-barrier feature. Further, the tensile strength (TS) and elongation at break (EAB) were reduced with the increase of PC content in G-based films, and were inversely correlated to films thickness with respective R-2 values of 0.94 and 0.97. Regarding microstructure, PC eliminated cracks present in the control film matrix resulting in a more smooth structure. Moreover, PC addition contributed to the thermal stabilization of the gelatin chain, delaying the glass transition temperature by 20 degrees C and conferring a thermal stability up to 250 degrees C. Regarding the antioxidant activity, the incorporation of 12.5% of PC significantly increased by 4.09, 3.2, 13.6 and 1.47-folds the chelating, reducing, beta-carotene bleaching inhibition and DPPH radical scavenging capacities, respectively. Likewise, G-PC films displayed antibacterial activity against several Gram ( - ) and Gram ( + ) bacteria. The present study suggested that G-PC films incorporated with 6.25% and 12.5% of PC extracted from Arthrospira sp. could be used as a promising colored external or inner (secondary) functional packaging for dehydrated food products as well as for hard or soft-shelled capsules containing powdered or oily active ingredients, although further analysis should be carried out.
