Extraction and usage of pectin to enhance biodegradability of LDPE blends

Abstract

Blends of pectin and low density polyethylene (LDPE) were prepared and the effect of pectin on biodegradability was analyzed Pectin was extracted front passion fruit peels hy hot acid extraction with a yield of 20 wt.%. I he physical, mechanical and chemical properties of the blends were investigated using Fourier Transform Infrared spectroscopy (f IIR). tensile test, water absorption test and optical and electron microscopy. The biodegradability wits evaluated by time dependent weight loss using soil burial test. The test results showed that weight loss up to 4.5% in 14 weeks period. Pectin addition had a positive impact on enhancement of biodegradability of LDPE blends.
