based crackers. Central composite rotatable design with three independent variables–BRF
(10–40%), carboxymethyl cellulose (CMC)(1–3%), and shortening (5–12%)–produced 20
different combinations. Response surface methodology was used to study the effect of
different levels of BRF, CMC, and shortenings on product characteristics like spread ratio,
volume index, density, width, thickness, and puffiness. All the three independent variables …
