Abstract

The objective of this study was to investigate the physical, nutritional and sensory characteristics of Éclair substituted with different levels (0, 10, 20, 30, 40 and 50%) of purple sweet potato flour (PSPF) as sources of anthocyanin. colour parameters (lightness (L*), redness (a*) and yellowness (b*)) of all Éclair were measured using a Hunter colorimeter. L* and b* values of Éclair decreased while a* value increased with increase in level of PSPF from 0 to 50%. Sensory evaluation showed that Éclair substituted with 30% PSPF was acceptable. In addition, colour and sensory qualities of patties incorporated with purple sweet potato (PSP) at different levels (0, 15, 20 and 25%) were studied. PSP addition up to 25% had effect on the colour of patties and increased a* value, while decreasing the L* and b* values of the patties. The patties incorporated with 25% PSP improved the overall sensory acceptance. The analysis of chemical composition of Éclair (100 grams) had carbohydrate content of 26.85%, protein content of 5.50%, fat content of 11.38%, ash content of 0.90%, moisture content of 55.37% and found microorganism less than 1.8 x 103 (CFU/g). Therefore, it can be concluded that the Éclair substituted with 30% PSPF and patties incorporated with 25% PSP improved the nutritional and the sensory characteristics of Eclair products.
