Tóm tắt

In response to the growing need for sustainable food packaging, this study explores using nature-based
materials, specifically Pectin and Carboxymethyl Cellulose (CMC) derived from grapefruit peels, as
alternatives to petroleum-based packaging films. These materials function as effective barriers, creating
modified atmospheres that reduce respiration rates, minimize moisture exchange, and delay deterioration.
Characterization of the fabricated Pectin/CMC films was determined through scanning electron microscope
(SEM), reflection infrared spectrum (ATR-FTIR), water contact angle (WCA), and mechanical properties.
The preservation ability of green grapes was compared with the preservation ability of commercial
Pectin/CMC films during 10 days of preservation. Experimental results showed that the Pectin/CMC film
made from grapefruit peels and the Pectin/CMC film made from commercial Pectin, CMC are suitable for
food preservation. However, the food preservation ability of Pectin/CMC films formed by Pectin, CMC
isolated from grapefruit peels showed higher retention of fruit weight and decreased organic acid content.
This demonstrates the potential of the Pectin/CMC film as a superior alternative for sustainable and
efficient grape preservatio
