Maleic and Sulfosuccinic Saturated Aliphatic (C18) Monoesters with Heterogeneous Polyoxyethylene (n=8) Chains - Potential Agroalimentary Pellicular Protection Systems

Natural vegetable waxes in general and the epicuticular in particular, present on the surface of many horticultural products (fruits, vegetables), confer upon them two distinct competences: controlled permeability for water transfer, and respectively for gas transfer in the respiratory process, which significantly affects their window-shop quality. The knowledge and recognition of these qualities has stimulated the study of food product–environment interphase mass transfer mechanisms, along with the diversification of the range of biocompatible synthetic epicuticular waxes that would allow the post-harvest application of protective films. This paper aims to present the possibility of diversification, preparation and basic physico-chemical characterization of the sodium salt of maleic [MEM-ST (n=8)(H)(Na)] and sulfosuccinic monoester [MESS-ST (n=8)(H)(Na)] respectively with heterogeneously polyethoxylated (n=8) stearin, obtained by an adapted classical reaction scheme.
