Abstract One of the innovation strategies of the bakery industry is the use of new ingredients capable of increasing the health appeal of products. The objective of this study was to evaluate the effect of partial substitution (15%) of wheat flour by young bamboo culm flour (YBCF) in cookies formulations, using a central composite design with two variables (sugar and fat reductions) and three replicates at the central point. Formulations were selected by surface response methodology (p<0.10) and evaluated over 28 days of storage for stability and nutritional composition. Only sugar reduction led to significant differences in the diameter of the cookies. Formulations with 50% of reduction of sugar and fat (F2 and F3, respectively) were selected for the...

ABSTRACT: Response surface methodology was used to determine optimum conditions for extraction of protein from pumpkin seed meal. A central composite rotational design (CCRD) including independent variables such, pH and sodium trimetaphosphate (STMP) content was used. Maximum yield was obtained at a central point of CCRD, with STMP content and pH of 4% and 4.5, respectively. These conditions resulted in protein yield of 50.04 g of soluble protein from extract/100 g pumpkin seed. The optimization of pH and STMP content allowed obtaining a product with a high protein concentration (62.56 g 100 g-1), digestibility (62.03 g 100 g-1) and concentration of essential amino acids (27.26 g 100 g-1). Regarding the polyphenols concentration, phosphorylated protein...
