Abstract

The present study aimed to reformulate chicken nuggets with reduced sodium content, replacing the NaCl with CaCl2 and assessing the physicochemical and sensory properties of the obtained products. Four treatments of chicken nuggets were processed: Control formulation (1.5g NaCl/100g) and three treatments containing CaCl2 substituting 25, 50 and 75% of the NaCl, considering an ionic strength equivalent to 1.5% NaCl. The four different chicken nuggets were similar (p>0.05) for the variables oil absorption, lipid, protein and moisture contents, water activity, cooking yield, pick-up and texture profile analysis. However, a decrease in ash content (2.21-1.75g/100g) was observed. The replacement of 75% NaCl could reduce 34% sodium in chicken nuggets with a concomitant increase in the calcium content (10-130mg/100g). For objective colour, the brightness (L{*}) increased from 74.43 to 78.28 as CaCl2 contents increased in the chicken nuggets, but the a{*} and b{*}parameters did not show differences (p>0.05) among all treatments. Sensory acceptance (texture, flavour and overall quality attributes) did not differ between Control and the 75% sodium reduction treatments (all values around 7.5 in the 9-point hedonic scale), despite the decrease in the salty taste observed in the just about right scale test. Thus, the maximum tested replacement of 75% NaCl by CaCl2 produced healthier chicken nuggets, for having provided a reduction in sodium content and increase in calcium content, besides maintaining sensory quality and most of the technological characteristics.
