Thus, new combinations of biodegradable materials for food packaging have become the target of frequent research. The present study aimed to produce and evaluate active biodegradable films based on red bean flour and acai seed extract and also to evaluate the quality of extra virgin olive oil stored in packaging produced for a period of 16 days at 60 degrees C. Films of red bean flour (Phaseolus vulgaris) with 0.5% and 10% acai seed extract were developed. The addition of the extract to the films increased their tensile strength by 100%, reduced their solubility and transparency, and increased their relative crystallinity. Furthermore, the antioxidant activity presented by the films increased in line with the concentration of extract added. The extra virgin olive oil was packaged in materials produced from bean flour films with 10% extract and maintained its quality parameters within the limits established by legislation. These results suggest the discovery of a biodegradable and antioxidant packaging that can be used to pack olive oil and other fatty food products.","PeriodicalId":20308,"journal":{"name":"Polymer Engineering & Science","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82262404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
