Abstract
The Physical and sensory characteristics of muffins prepared with flavonoids such as ferulic acid and p-hydroxybenzoic acid were evaluated for the development of functional foods using these flavonoids. The solubilities of ferulic acid and p-hydroxybenzoic acid were over 1% in water and the solutions showed a good thermal stability. However, 1% ferulic acid and p-hydroxybenzoic acid solution showed a color change during heating. The volume and maximum height of the control muffin were the greatest among the muffin groups. The volume of the muffins decreased with the increase of flavonoid concentration. The volumes of muffins with p-hydroxybenzoic acid were smaller than those of muffins with ferulic acid. The L, a and b values on crust and crumb of the muffin groups were not significantly different. The chemical flavor, bitterness and after taste of the muffins prepared with ferulic acid were stronger than those of the control muffins. Savory flavor and sweetness of the muffins with ferulic acid were weaker than those of the control muffins. The muffins with p-hydroxybenzoic acid were not significantly different from the control muffins in the appearance, flavor, taste, texture and overall acceptability. These results demonstrated that p-hydroxybenzoic acid may be useful as an additive to muffin.
