Abstract

The rheological and optical characteristics of pectin aqueous solutions containing plant and beeswax are considered. The results obtained can be used in the production of pectin- and wax-based emulsion coatings to prolong the shelf-life of food products. The applicability of the models of Oswald-de Waele, Casson, Herschel-Buckley, and Newton to describe the rheological behaviour of pectin emulsion solutions is examined. A spectroturbodimetric method is proposed to assess the stability of the solutions..

Keywords
