Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a waste stream, promoting sustainability.
- +Employs green extraction solvents.
- +Provides quantitative data on polyphenol content and antioxidant activity.
Limitations
The availability and consistency of waste materials can be a challenge. Scaling up extraction processes from lab to production can be complex and costly.
Reliability & validity
The study uses established analytical techniques (HPLC-DAD, Folin-Ciocalteu, DPPH) and reports statistical data (mean ± standard deviation), suggesting good reliability and validity for the reported findings. Replicating the procedure with the same solvents and waste material would be necessary to confirm results.
