“…Our study was chosen to obtain products with maximum CV, WAI, paste clarity and gel hardness and minimum gel cohesiveness and retrogradation. The search for optima were performed by a subroutine written in MULTIPLEX computer program (da Silva, 1999). This computer program combines RSM and super-modi®ed simplex optimization by the function of Derringer (Derringer & Suich, 1980), that involves transformation of each variable (y i ) to a desirable value d i , where 0 £ d i ³ 1.…”

“…The microcomputer program MULTIPLEX, which combines RSM with super-modi®ed simplex optimization, was developed for the treatment of cases which are interesting for food science and technology through the application of the function of Derringer (Derringer & Suich, 1980). The program has shown itself to be ecient for the optimization of multiresponse data (da Silva, 1999).…”

Acetylated, cross‐linked and pregelatinized cassava starches were produced in a single‐screw extruder with different moisture contents (180, 220 and 260 g kg–1), reagent (adipic acetic mixed anhydride) concentrations (4, 11 and 18 g kg–1) and screw speeds (100, 130 and 160 r.p.m.). The acetylation, cross‐linking and pregelatinization increased cold viscosity (CV), water absorption index (WAI) and gel hardness, it also reduced gel cohesiveness, paste clarity and retrogradation of the modified‐starches compared with control samples (CSs). A novel microcomputer program called MULTIPLEX was developed for the optimization of the process. The optimization process maximized CV, WAI, gel hardness and paste clarity, and minimized gel cohesiveness and retrogradation of the modified‐starches. The optimum conditions were moisture of 240 g kg–1, reagent concentration of 4 g kg–1 and screw speed of 100 r.p.m. Experimentally determined values for all responses found in products processed under the optimum conditions were very close to the predicted values and this confirmed the validity of predicted models.

“…A otimização foi realizada pela superposição das curvas de nível consideradas mais aceitas (Figuras 9 e 10) para as respostas: aceitação do gosto salgado e atividade de água. A superposição destas duas curvas resultou na região de compromisso (Silva et al, 2000), onde foi realizado um experimento para comprovação (Figura 11). Este experimento também teve o objetivo de comparação com um controle (sem adição de lactato de sódio).…”
