TL;DR
This study created a biodegradable chitosan film with Ashwagandha extract to extend the shelf life of fresh-cut strawberries by reducing microbial growth and decay.
Contribution
The novelty lies in using Ashwagandha extract in chitosan films for sustainable, antimicrobial food packaging.
Findings
ASH3/Cs film showed potent antibacterial activity against multiple pathogens.
The film reduced microbial growth, weight loss, and decay in strawberries over 9 days.
ASH3/Cs film improved hydrophilicity and showed potential as a sustainable food packaging alternative.
Abstract
The current study aimed to develop biodegradable chitosan (Cs) films enriched with Ashwagandha (ASH) extract as an active packaging material to extend the shelf life of fresh-cut strawberries. The ASH extract, obtained through methanolic extraction, demonstrated significant antimicrobial and antioxidant activities, as confirmed by Gas Chromatography-Mass Spectrometry (GC-MS), which identified 12 bioactive compounds, including n-hexadecanoic acid (30.42%) and cis-13-octadecenoic acid (31.68%). The ASH loaded Cs films, prepared at varying concentrations of ASH extract, were characterized for surface morphology, water vapor transmission rate (WVTR), oxygen permeability (OP), and water contact angle (WCA). The films' hydrophilicity was improved with increasing ASH concentration, reducing the WCA from 112.4° (Cs) to 77.3° (ASH6/Cs). Antibacterial evaluation of the ASH3/Cs film revealed…
