| Popis: | The increase of soluble solids in milk by the addition of powdered products is a normal practice in the elaboration of yogurt in order to enhance viscosity, texture and sensory properties for the consumer. The purpose of this study was to evaluate the effect of adding jumbo squid (Dosidicus gigas) powder (protein content, 420 g/kg) on the aforementioned quality properties of yogurt. Six formulations of yogurt were prepared with the addition of 0, 1, 3, 5, 7 or 10 g/100 mL jumbo squid powder, plus one formulation with 3 g/100 mL maltodextrin. During fermentation, yogurts formulated with squid powder gradually achieved greater viscosity while producing both more acidity and at a higher rate than the controls. Apart from lower pH (hence, higher titratable acidity) and higher viscosity, the final enriched yogurts presented lower syneresis than the controls (p < 0.05). Although the highest viscosity (58.90 Pa.s) and the lowest syneresis (1.00%) was achieved by the yogurt with 10 g/100 mL jumbo squid powder, it was the treatment formulated with 3 g/100 mL (pH 4.31, acidity 0.85 g/100 g, viscosity 40.90 Pa.s and syneresis 9.10%) that kept constant sensory properties, as evaluated by the panelists, while improving some physical properties of the control yogurts. The authors are grateful to Biologist Armando Solari and the Technological Institute of Production (ITP, Peru) for all support provided in the conduction of this research.
