Impact of using oat flour and erythritol on characteristics and glycemic index of chiffon cakes and study the effect of erythritol on cavity- causing bacteria

Abstract

Oats have a high content of β-glucan. Its consumption lowers cholesterol and the glycemic response. One of the main components of many baked confectionery goods is sucrose. Reducing the amount of refined sugar in food has become urgently necessary as a result of the growing understanding of the link between excessive sugar consumption and the emergence of chronic diseases. Oat flour in the chiffon cake formulation was replaced at three levels, 50, 75 and 100% with wheat flour and had sucrose replaced with erythritol. Raw materials and prepared chiffon cake samples were analyzed for their chemical composition. Final product was evaluated for baking quality, glycemic index (GI) and organoleptic Properties of chiffon cake. The inhibitory effects of erythritol on Streptococcus strains were examined. Results suggest that, it could be seen that a significant increase in fiber and fat contents (10.1 and 6.52%, respectively) and a decrease in carbohydrate content 68.79%, in oat flour compared to wheat flour. Our results indicated that in the presence of erythritol was decreased the growth of S. sanguinis by 73%. Chiffon cake produced with oat flours and erythritol it was characterized with their higher content of moisture, ash and fiber. The highest weight (360.0 g) was given by adding 100% oat flour to the chiffon cake sample compared to 342.6 g for control cake. The GI were decreased as the levels of oat flour were increased and substituted sucrose with erythritol. Chiffon cakes prepared with 50% oat flour and 100% erythritol was decreased in sweetness
