Abstract: | "Sensory and nutritional properties of mango pulp thawed by different ultrasound intensities and temperatures were studied. Compared to water immersion thawing, a thawing time reduction of 16-64% (p?ª+ª+0.05) and more phenolic acids contents (gallic, hydroxybenzoic, and caffeic acid) were observed after ultrasonic thawing. The sensory evaluation revealed texture and aroma deterioration at higher ultrasonic intensities (4?ª+ degrees C:0.074?ª+W/mL; 25?ª+ degrees C:0.123?ª+W/mL) due to increase in viscosity and some volatile compounds in the mango pulp. Ultrasonic thawing treatment at 25?ª+ degrees C reduced thawing time by 51-73% compared to that at 4?ª+ degrees C. Mango pulp processed at 25?ª+ degrees C exhibited better sensory quality and retained 26.5-58.5% more total phenol and 8.7-11.0% more total carotenoid contents. In short, higher ultrasonic intensities (0.074-0.123?ª+W/mL) at a temperature of 25?ª+ degrees C contributed to better thawing efficiency and nutritional quality. The results demonstrated that ultrasound processing at optimized conditions could serve as a potential alternative to conventional thawing processing of mango pulp" |
