Developing active and intelligent films through the incorporation of grape skin and seed tannin extracts into gelatin

To achieve sustainability in the wine industry, by-products from winery operations are being diverted from waste streams and turned into beneficial use. Grape seed tannin (SeedT) and skin tannin (SkinT) extracts were used to modify the properties of gelatin films, and to prepare active/intelligent f...

Grape seed tannin (SeedT) and skin tannin (SkinT) extracts were used to modify the properties of gelatin films, and to prepare active/intelligent films. The SeedT extract showed a higher phenolic content (similar to 440 mg gallic acid (GA)/g extract) and antioxidant inhibition (similar to 20 %) than the SkinT extract (14 mg GA/g extract, 2 % antioxidant inhibition), while both extracts presented colour variations with an increase of solution pH. The addition of extracts into the gelatin formulation resulted in coloured and transparent films with lower wettability (water contact angle increased up to 92 degrees) and higher UV-light absorbance (secondary antioxidant function) properties. The films were capable of releasing tannins by up to 20 % which led to antioxidant inhibition values of up to 13 % (primary antioxidant function). The addition of SkinT tannins into the films provided the films with a pH indicator ability (intelligent function).The authors would like to thank the State Research Agency of Spain within the Juan de la Cierva - Incorporation action (IJC2019-039697I) and the Ministry of Business, Innovation and Employment (MBIE, Biocide Toolbox programme).Elsevier202220222022info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10810/58245reponame:Addi.
