Pea protein–sugar beet pectin binders can provide cohesiveness in burger type meat analogues

Abstract

AbstractMethylcellulose is commonly used in meat analogues for binding ingredients. In this study, we compared the binding properties of a methylcellulose hydrogel (5% w/w) to a novel, clean-label binder based on a mixture of pea protein and sugar beet pectin (r = 2:1, 22.5% w/w, pH 6.0) with and without laccase addition in a burger type meat analogue. It was shown that the pea protein–pectin binder glued vegetable protein particles and fat mimic particles together prior to cooking and frying, thereby improving forming of the mass into burger patties. Furthermore, sensory analysis revealed that the cohesiveness of the fried burger patties was better when the protein–pectin binder was used. However, the used binder system did not affect the hardness of the burger patties indicating that the binders rather affected the coherence of the structural elements. Burgers with solid fat particles were rated better in terms of appearance as compared to emulsified fat particles, since the former were not visible. This study is useful to better understand meat analogue product design for a higher acceptance among consumers.
