Abstract: The objective of this research was the elaboration of extracts from the solid industrial waste of Litopenaeus vannamei shrimp and to define the extract with the highest acceptance rate and highest extraction yield through physicochemical, microbiological and sensorial analysis. The extracts were obtained through a process of lyophilization of the liquid extracts from the baking of the waste. Three types of extracts were prepared with different raw materials- Ecasca (shells), Ecefa (cephalothorax) and Emix (50% shells±50% cephalothorax). With the exception of humidity, all other physical-chemical parameters presented significant differences between them. All data from the microbiological analysis were within the limits required by current Brazilian legislation. In the sensory evaluation, all the extracts were well accepted, the Ecefa being the treatment that obtained the highest index of acceptability for the aroma and flavor. The Ecefa treatment obtained the highest extraction yield. In view of the obtained data, it was possible to determine that the Ecefa treatment would have a greater potential as an extract to be applied in foods that can present shrimp aroma and flavor, thus contributing to the use of shrimp industry waste in the offer of a natural aromatic extract and for the preservation of the environment by avoiding the disposal of such waste improperly.
