ABSTRACT
Short dough biscuits were prepared using interesterified trans free bakery shortening (IETFS). Hydrogenated shortening (HS) based biscuits were prepared as a control. The diameter, height and spread ratio were determined. Biscuits were analysed up to 8 months for hardness, moisture and acidity of the extracted fat. IETFS biscuits were significantly (P < 0.05) less hard, had a higher spread ratio and were rated higher on all sensory attributes. Their overall acceptability score on a nine point hedonic scale was 8.2 ± 0.8 as compared to 7.3 ± 0.7 for control biscuits. The fatty acid fraction of control biscuits was: saturated fat, 51.6%; trans fat, 14.5%; monounsaturated fat, 28.0%; and polyunsaturated fat, 5.9% and that of IE trans free biscuits was: saturated fat, 54.8%; trans fat, 0.6%; monounsaturated fat, 38.1%; and polyunsaturated fat, 6.5%. The IETFS was found to be appropriate as an alternate to hydrogenated shortening, providing both functionality and nutritive advantage in biscuits.
