Opuntia species contain functional components like mucilage, a polysaccharide crucial for water storage, found mainly in cladodes. The extraction method plays a decisive role in determining both the yield and the technological properties of the resulting mucilage powder obtained after dehydration. This study optimized mucilage extraction using a Box-Behnken design, analyzing pH (5–9), solvent-solute ratio (20–30 mL/g), and microwave-assisted extraction time (3–7 min) to maximi...
Opuntia species contain functional components like mucilage, a polysaccharide crucial for water storage, found mainly in cladodes. The extraction method plays a decisive role in determining both the yield and the technological properties of the resulting mucilage powder obtained after dehydration. This study optimized mucilage extraction using a Box-Behnken design, analyzing pH (5–9), solvent-solute ratio (20–30 mL/g), and microwave-assisted extraction time (3–7 min) to maximize yield (18.18%), viscosity (49.00 Pa·s), and water-holding capacity (6.84 g/g). Optimal conditions were pH 7,25 mL/g SSR, and 4.5 min MAET. FTIR identified polysaccharide typical groups (–OH, –C = O, C-O-H), while XRD confirmed an amorphous structure. The mucilage comprised ash (20.83%) and carbohydrates (64.14%), including galactose (15.80%), arabinose (12.26%), xylose (4.72%), and glucose (4.36%). It exhibited high solubility (71.53%), swelling capacity (23.76%), and emulsifying stability (> 47%), with potential for food applications due to its functional properties. The results highlight Opuntia mucilage as a promising natural ingredient for the food industry.
