In view of the increasing interest in the use of residues from the food industry as source for packing applications, the by‐product of the mechanical extraction of avocado oil is an attractive product as it consists basically a hydrated and defatted pulp, rich in proteins, fibers. and oil. This work aims to produce biobased polymer films from avocado oil extraction residue. Seven film‐forming solutions were elaborated from puree and the additives tested were glycerol, cassava starch, and microcrystalline cellulose. The films obtained from the pure residue presented brittle behavior. All films presented low values of water vapor permeability (0.064 to 0.446 g mm m−2·kPa−1 h−1) and medium water soluble fraction (43.79 to 56.92%). The films with cassava starch and glycerol presented the best results, with mechanical (tensile: 2.70 MPa; elongation: 13.7%) and thermal properties in the range typically found in the literature for biobased films. © 2016 Wiley Periodicals, Inc.

Brazil is one of the largest food producers in the world and also one of the most socially and economically unequal countries. Afro Veganism, Ghetto Veganism and Feminist Veganism are associated with this fight, addressing the contradictions between food, bodies, gender, and racism. This article aims to understand how these three collective movements articulate their discourses on veganism, highlighting the similarities and differences between their narratives, and thus understand the discourses of the vegan movement, considering the symbolic dimensions of food within the context of Brazilian socio- economic inequality. For the examination of the discursive content collected, intersectionality was used as an analytical tool. The analysis of these initiatives reveals a critical look on “traditional” veganism, criticismo of the [whitened] perspective of the vegan movement, the uncritical assimilation of products from the big agro-industry, the difficulties of accessing fresh food, the exploitation of human and non-human resources, especially feminine ones, and the relationship between speciesism and racism.
