Specifically, ultrasound cavitation will enhance mass transfer and microwave irradiation will provide rapid and uniform heating, leading to more efficient pectin extraction with improved functional properties. A full factorial experimental design (2³) was employed, analyzing the effects of three independent variables: temperature (°C), microwave power (W), and ultrasonic amplitude (%), on both pectin yield and its quality parameters, such as degree of esterification and sugar composition. Statistical validation was performed using ANOVA and Tukey's post-hoc test to confirm significant differences among treatments. Under optimal conditions (60°C and 500 W with 50% amplitude and 3 min duration), the pectin extraction process achieved a maximum yield of 65.40% (p < 0.001, η² = 0.961, 95% CI: (59.88%, 63.37%)). The derived pectin exhibited exceptional physicochemical attributes, including 78.67% (p < 0.001, η² = 0.954, 95% CI: (69.5%, 79.1%)) anhydrouronic acid, 81.56% (p < 0.001, η² = 0.950, 95% CI: (71.8%, 81.6%)), galacturonic acid content, and a 70.48% (p < 0.001, η² = 0.948, 95% CI: (61.8%, 70.2%)) degree of esterification, qualifying it as high-methoxyl class pectin with superior gelling and emulsifying properties. UMAE resulted in improved performance indicators, such as a water holding capacity of 11.01 g/g (p < 0.001, η² = 0.996), an oil holding capacity of 5.42 g/g (p < 0.001, η² = 0.990), an emulsifying activity index of 65.40%, and foam stability of 93.25%. Additionally, the method reduced overall extraction time by 70% (p < 0.001, η² = 0.970) and energy usage by 38.84% (p < 0.001, η² = 0.967), significantly contributing to sustainable production. While UMAE demonstrates improvements in extraction time and energy efficiency, claims of sustainability require further validation through life cycle analysis (LCA) and techno-economic assessments. These analyses would help quantify the environmental and economic impact of UMAE at an industrial scale. pubtype: Academic Journal doctype: equations & formulas research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
