05) from the Control sample. The mathematical model (R2 = 0.87; Fcalc/Ftab = 6.36) for the dependent variable of aroma acceptance is shown in Equation (8). equation(8) Aroma=6.31−0.45MO+02.23MOAroma=6.31−0.45MO+0.23MO2 It can be observed that only the concentration of MO had an effect on this response, and an increase of MO resulted in a reduction of the aroma acceptance. It was not possible
to obtain a response surface for the dependent variable flavor acceptance, due to the coefficient of determination (R2) being less than 0.77 and the ratio calculated F/tabled F being lower than 3, indicating a relevant lack of fit in the analysis of variance of the regression. Samples 3, 4, 5, 6, 8, 9 and 11 presented average scores for flavor acceptance between “neither liked nor disliked” http://www.selleckchem.com/products/BKM-120.html and “liked very much”, differing statistically (p < 0.05) this website from the Control. Samples 1, 2, 7 and 10 (in general, with lower concentrations of MO, ≤2.5 g/100 g) did not statistically differ (p > 0.05) from the Control. In the work of Serna-Saldivar et al. (2006), samples of bread containing microencapsulated omega-3
showed results between “liked slightly” and “liked very much” in the course of 13 days of evaluation, in relation to flavor. Five panelists identified fish flavor in Samples 6 and 9, three pointed out an excess of salt in Sample 7, and three complained that they could not notice the rosemary extract. The mean scores for texture acceptance ranged from “neither liked nor disliked” to “liked moderately”. Samples 3, 6, 8 and 10 (in general, with higher concentrations of MO, ≥2.5 g/100 g) statistically differed (p ≤ 0.05) from the Control. These samples also showed elevated levels of firmness (>8.7 N) in the instrumental texture analysis. It was not possible to obtain a response surface for the dependent variable PIK3C2G texture acceptance, because the coefficient of determination (R2) being less than 0.64 and the ratio calculated F/tabled F
was below 3, indicating a significant lack of fit in the ANOVA of the equation. According to Serna-Saldivar et al. (2006), breads enriched with DHA microcapsules presented average scores between “liked slightly” and “liked very much”. Five panelists included comments with respect to the texture of the breads, referencing that some samples were dry, sticky and had a sandy aspect. The mathematical model (R2 = 0.85; Fcalc/Ftab = 5.04) for the dependent variable of overall acceptance is shown in Equation (9). equation(9) Overallacceptance=6.30−0.48MO+0.29MO2 It is possible to observe that only the concentration of MO had an effect on this response, and that an increase of MO resulted in a reduction of overall acceptance. However, within the ranges studied, all scores were acceptable (>5). It was not possible to obtain a response surface for purchase intention, because the coefficient of determination (R2) of the equation was inferior to 0.70.
