  • This study was carried out to evaluate the sensory evaluation of the muffins with mulberry leaf powder as well as their chemical characteristics. The muffins were prepared by adding 0%, 1 %, 2% and 3% mulberry leaf powder to the recipe. As a result of the sensory evaluations, the color, flavor and texture of the muffins of 2% mulberry leaf powder were found to be much better than those of the other groups. In the chemical composition analysis, increasing the mulberry leaf powder led to a significant increase in the content of crude protein, moisture and crude ash, while crude fat was significantly decreased. As the ratio of mulberry leaf powder increased, Ca, Mg, Fe and Zn in the muffins increased proportionally (p<0.05). The lightness value, the redness value and the yellowness value decreased with the increase of mulberry leaves powder content. In a texture analyser test, hardness and cohesiveness decreased as the ratio of mulberry leaf powder increased. The adhesiveness of the muffins with 2% mulberry leaf powder was the strongest of all.

  • The overall effects of three different beers on white bread were examined in terms of mixograph, pH, fermentation rate, TPA, crumbScan, colorimeter, sensory evaluation, and the hardness of bread through different storage times (0, 1, 2, 3 days), and texture as measured by texture analyzer. According to mixograph, the control (CON), black beer stout (BOB) and Asahi beer (AOB) but not max beer (MOB) were found to be proper between 3 and 5 minutes of peak time. All samples for peak value were at the level of over 60%. AOB showed the highest specific volume, and was the lowest in hardness (i.e. highest in softness) by TPA and storage days. In sensory evaluation, the difference test showed that AOB had the best volume, springiness, moistness, and softness. Moreover, in an overall preference test AOB scored the highest points in texture, flavor, taste, and overall acceptance.
