Microbial, physical and sensory attribute of cookies produced from wheat flour fortified with Termitomyces robustus and spiced with curry leaves (Murraya koenigii).

ABSTRACT

Wheat flour was used to substitute mushroom flour at the ratio of 7030 as category A, 5050 as category B, 3070 as category C, and each categories were substituted with spice (Murraya koenigii) at concentration ratio of 5g, 10g, and 15g respectively. The cookies prepared without wheat flour and also without mushroom flour serve as positive control. The spread ratio was determined with meter rule Total Staphylococcus, Bacillus, Coliform and Fungi count were determined using standard microbiological procedure and the effect of the spice (Murraya koenigii) concentration was noted. Consumer preference or otherwise was also determine using a taste parnel list. The mean quality scores of microbial count, Staphylococcal count and Fungi count reduces significantly at p<0.05 as the spice concentration increases but the Bacillus proves resistant to the effect of the spice. The mean quality sensory scores of the cookies range from colour (3.55 – 3.45), flavour (4.9 – 3.5), taste (4.9 – 3.0) and overall acceptability (5.0 – 3.0) for 7030. Colour (4.9 – 3.0), flavour (4.0 – 3.5), taste (4.9 – 3.0) and overall acceptability (4.9 – 3.0) for 5050. Colour (3.5 – 2.0), taste (2.5 – 2.0) and overall acceptability (3.0 – 2.0) for 3070 respectively. The result shows a significant difference at probability level P<0.05 as the spice concentration increases for category A and B but C display no significant difference. the production of cookies from wheat flour fortified with (Murraya koenigii) be encouraged to achieve and harvested the preservatives, potential of the spice (Murraya koenigii) and the other medical properties that has been recorded from literature review.
