Effect of sodium chloride replacement and apple pulp inclusion on the physico-chemical, textural and sensory properties of low fat chicken nuggets

Abstract

The effect of 40 percent sodium chloride replacement with salt substitute blend (potassium chloride, citric acid, tartaric acid and sucrose) and incorporation of apple pulp, at the levels of 8 (Treatment I), 10 (Treatment II) and 12 (Treatment III) g/100 g of formulation, on the various quality characteristics of low fat chicken nuggets was investigated. Emulsion and product pH values were significantly higher ( P < 0.01) for the control when compared to treatments. Salt replacement and apple pulp addition resulted in significantly lower ( P < 0.05) emulsion stability and cooking yield. Among low salt and low fat nuggets, the product with 12 g/100 g apple pulp had the highest moisture percent. Protein and ash contents were significantly lower ( P < 0.01) in treatment products, whereas moisture protein ratio was higher. Incorporation of apple pulp significantly increased ( P < 0.01) dietary fibre content, redness, yellowness and chroma index of the product. Textural properties of the products significantly decreased ( P < 0.01) with substitution of common salt and addition of apple pulp. Sensory evaluation showed significant reduction ( P < 0.01) in texture and overall acceptability scores of treatment products; however, scores were in the range of very good.
