Abstract

Coproducts from different agroindustrial segments, such as spent coffee, cocoa husks and palm pressed fiber, are generated in large quantities and are usually burned in the industries themselves for power generation. This industrial practice can be changed if strategies of adding value are adopted for the valorization of these materials, which may present very interesting characteristics, such as significant contents of lipids and / or minority compounds. In this sense, it is worth mentioning that the oilseed processing industries use for the extraction of vegetable oils a solvent, a mixture of isomers of n-hexane, which has high flammability and high polluting capacity, besides being considered neurotoxic. In this context, it can be inferred that the proposed research project is supported by the following pillars: minimization of agroindustrial waste with possible production of inputs for the food, cosmetics and pharmaceutical industries, using renewable and safe solvents for extraction, such as ethanol. Thus, the aim of this project is to study the technical feasibility of total or partial substitution of the solvent commonly used in the process of extracting vegetable oils by short chain alcohols, ethanol and isopropanol, generally recognized as safe (GRAS), or less toxic hydrocarbons with a low human health risk, such as heptane and cyclohexane. The project will be conducted in three different arms: a) Study of kinetics of extraction and determination of partition coefficients of vegetable oils in extraction experiments under atmospheric pressure using alcohols as solvents; b) Study of the use of mixtures of solvents, hydrocarbons (hexane, heptane and cyclohexane) and alcohols (ethanol or isopropanol), with the choice of the compositions of the mixtures being based on the calculation of solute-solvent distances, according to the Hansen methodology; c) Study of the intensification of the extraction process through the use of pressurized liquid extraction (PLE) and ultrasound assisted extraction (UAE), in order to obtain vegetable oils enriched in minor compounds such as chlorogenic acids, alkaloids, flavanoids and carotenoids.
