The aim of this study was to investigate the effectiveness ultrasound as a conservation method for inactivation Escherichia coli inoculated into cactus pear juices (green and purple). Total soluble solids, pH, titratable acidity, kinetics E. in treated by (60%, 70%, 80% 90% amplitude levels 1, 3 5min) were evaluated over 5 days. observed both fruit after 5min treatment at most (with exception 60% 80%). After one two days storage, recovery bacteria counts all juices. Ultrasound resulted...
The aim of this study was to evaluate the stability color, betaxanthin, and betacyanin pigments in presence Cu(II)-dependent hydroxyl radicals (HO•) from ultrasonicated purple cactus pear juice at amplitudes 40%, 60%, 80%, comparison untreated sample. L* parameter treated 40% 80% amplitude for 25 15 min, respectively (11.3 9.3, respectively), were significantly higher compared control; b* hue parameters min showed values 1.7 0.1, respectively. Color differences (ΔE) lower (<3) juices high...
