The complex mixture studied, a hydrolyzed soy protein (HSP), κ-carrageenan (κC), and an hydroxypropyl methylcellulose (HPMC), could be used as a foaming agent under refrigeration or heating conditions because of the presence of one polysaccharide (HPMC) that gels on heating and another (κC) that gels on cooling. The objective of this work was to study the role of these polysaccharides on foaming properties by whipping methods at heating conditions. For this purpose, response surface methodology was used to optimize the mixed product in foamed food systems. The obtained results showed that the combination of E4M, κC, and HSP is an adequate strategy to generate good foam capacity and stability at heating conditions. The huge stability increase of foams at heating conditions was ascribed to combined effect of polysaccharides: gelling property of E4M and the viscozieng character imparted by κC to continuous phase of foaming.

ABSTRACT Response surface methodology was used for assessing the role of various compounding ingredients, including zinc oxide, antioxidant, coagent, oil, and filler, in peroxide vulcanization of natural rubber. A face-centered central composite design with four factors at three different levels was used to obtain the relationship between vulcanizate properties and the level of ingredients. The four factors selected were filler and oil ratio and the contents of zinc oxide, antioxidant, and coagent. The filler and oil ratio was kept constant throughout the experiment. The vulcanizates were evaluated for their mechanical properties: tensile strength, elongation, modulus (M100), tear strength, hardness, compression set (70 and 100 °C), and crosslink density. Regression equations were generated to model the properties of interest, and response surfaces and contour diagrams were plotted.
