Besides, mushrooms are a richer source of antioxidants. However, it is imperative to analyze all the available varieties of mushrooms for bioactive potentials like tyrosinase and antioxidant levels.

The chemical composition of propolis from stingless bees is affected by several factors including vegetation type and species. In Kenya, we have diverse landscape vegetation and over 12 stingless bee species. Lifestyle diseases are affecting more people due to unhealthy diets and exposure to harmful chemicals, which lead to oxidation in cells. This led to the production of super radicals, which cannot be neutralized only by the endogenous antioxidants in the body.

Higher drying temperatures increased the TS of the films whereas lower drying temperatures increased the MC, S, WVP and the EAB of the films. All the films prepared were transparent; however, films made with LMW chitosan were yellowish color. FTIR spectra of the films were influenced by the molecular weight of chitosan and the drying temperature, which revealed that there was an interaction between MW and the drying temperature.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>This study demonstrated that films made with medium MW chitosan by drying at room temperature had the most favorable properties for food packaging applications.</p>\u0000 </section>\u0000 </div>","PeriodicalId":93795,"journal":{"name":"JSFA reports","volume":"3 8","pages":"387-396"},"PeriodicalIF":0.0,"publicationDate":"2023-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsf2.142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50151337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
