Abstract The tanning i ndustry generates very large quantities of industrial wastes. The advancement of European policy and legislation protecting the environment has prompted the transformation of tannery solid waste materials into valuable co-products, useful to be recycled or employed in other industries. The objective of this work is to obtain gelatine from tannery wastes, in order to reuse it as natural microencapsulating agent in the production of active materials with functional properties. Concretely, this paper focuses on the influence of the extraction temperature on gelatine properties and its microencapsulating ability. An alternative enzymatic pre-treatment to the conventional alkaline one is… More >
