Sensory Properties Evaluation of Pine Nut (Araucaria angustifolia) Cereal Bars Using Response Surface Methodology
The objective of this work was to study the effect of crystal sugar/glucose concentration (SG - 40/60% wt to 60/40% wt) and Pine nut concentration (Pn - 0 to 20% wt in substitution of the oat bran) on the main sensory properties of cereal bars, following a 22 central composite rotational design (CCR...
