Extraction and process optimization of bael fruit pectin

Area of Science:

• Food Science and Technology
• Biochemistry

Background:

• Pectin, a crucial polysaccharide, is widely used in the food industry as a gelling agent, thickener, and stabilizer.
• Optimizing pectin extraction is essential for maximizing yield and achieving desired functional properties.

Purpose of the Study:

• To investigate the impact of extraction temperature, pH, and solvent ratio on pectin yield.
• To determine the optimal conditions for maximizing pectin extraction efficiency.

Main Methods:

• Pectin extraction was performed at two temperatures (100°C and 120°C) and two pH levels (1.5 and 2.0).
• Three different extraction ratios (ER) were employed: 1:1, 1:1.5, and 1:2 (solid-to-solvent).
• Statistical analysis using ANOVA was conducted to evaluate the significance of different extraction parameters.

Main Results:

• A significant difference in pectin yield was observed at 100°C and pH 1.5 across different extraction ratios (p < 0.05).
• No significant differences in pectin yield were found at 120°C and pH 1.5, nor at pH 2.0 with any extraction ratio.
• The highest pectin yield was obtained under the conditions of 120°C, pH 1.5, and an extraction ratio of 1:1.5.

Conclusions:

• Temperature and pH significantly influence pectin extraction, with higher temperatures and acidic conditions generally favoring yield.
• The optimal conditions for maximizing pectin yield in this study were identified as 120°C, pH 1.5, and an ER of 1:1.5.
• Further research could explore the impact of these conditions on pectin quality attributes.
