Abstract

Incorporating functional ingredients for producing a healthy gluten-free product is necessary to assess the impact on product characteristics and acceptability. This study aimed to determine the effect of eggplant flour and xanthan gum on gluten-free rice donuts. Four donut formulations were prepared by replacing rice flour with 10% and 20% eggplant flour and adding 0.5% and 1% xanthan gum (flour weight basis). The rice donut was the control. Physical properties on specific volume, firmness, and color, as well as sensory evaluation on a 9-point hedonic scale, were investigated. When replacing rice flour with 10% eggplant flour, the donut with 1% xanthan gum showed better specific volume and firmness but was darker and received more acceptable than that with 0.5% xanthan gum. The 20% eggplant flour replacement deteriorated rice donuts’ physical properties and sensory attributes. The preference mapping indicated that the rice donut with 10% eggplant flour and 1% xanthan was the best formulation.

Abstract

This present study aimed to enhance nutrients and reduce fat content in steamed pumpkin cakes. Two independent variables, including quinoa (30−80% w/w by pumpkin weight) and soymilk (15−60% w/w by coconut milk weight), were studied using response surface methodology. The statistical results showed that the quinoa inclusion had significant linear and quadratic effects (p<0.05). The soymilk showed a negligible effect, and there was no interaction effect between the two variables. Increasing quinoa has decreased all sensory scores of the samples, mainly when replacing pumpkin flesh with more than 50% quinoa inclusion. The pumpkin cake with 30% quinoa and 46% soymilk was the optimal formulation with a 0.936 desirability value. The optimal sample lowered all sensory attributes than the regular sample, particularly the appropriate qualities, such as unpleasant flavor and softer texture. About 54 percent of the consumers were willing to buy the product. The product is healthy with a 14.6% protein increment and 27% fat reduction.
