Abstract
This study aimed to evaluate the composition, the protein quality, and the acceptability of a powder dietary supplement formulated for elderly people. The centesimal composition was analysed according to A.O.A.C. methods and the protein quality was assessed in weaning rats, by comparing Protein Efficiency Ratio (PER), Net Protein Ratio (NPR), and True Digestibility (TD) of the supplement with a casein-control based on AIN-93G diet. For the acceptance test samples of four flavours of the supplement dissolved in whole milk were offered to each judge, in monadic form. To assess the overall acceptability a scale of seven points was used. The sensory panel was composed of 121 Brazilian panellists, with mean age of 68.28±5.78 years. The supplement is promising in reaching the nutritional demands of the elderly, providing high content of protein and fibre and low content of fat. The values found for PER and NPR were shown to be superior to the control group of casein (P<0.05) and the digestibility was higher tha...
