ISOLATION AND PERFORMANCE EVALUATION OF SACCHAROMYCES CEREVISIAE FROM ON PALM WINE (ELAELS GUINNEENSIS) AT DIFFERENT TEMPERATURE OF PROOFING DURING BREAD MAKING
ABSTRACT
Saccharomyces cerevisiae was isolated from the fermenting sap of flaeis guinneensis. The yeast isolate was used in dough proofing at different temperatures. The samples B, C, D, E, and F, (containing the same ingredients) were leavened at 200 c, 250 c, 300 c and 40 c respectively. Similarly, sample A which served as the contol was leavened at 30c. the following proof heights were recorded 3.3cm, 1.9 cm, 23cm, 3.5cm, 3.6cm and 2.5cm respectively for the proofing period, samples D and E compared favourably with the control which has a proof height of 3.3cm. The bread height, weight , volume and the specific volume was recorded sensory evaluation was carried on the samples for taste, appearance, texture flavour and overall acceptability. Turkeys test was in the samples. Result of the sensory evaluation showed that samples D ranked favourably with the control in all quality attributes tested at (D < 0.05). The other samples were different from the control in all the sensory attributed tested for A proofing temperature of 300c using the isolate was recommended for bread making in other to achieve the desired bread quality.
