The search for products containing natural ingredients has spurred researchers to develop biotechnological processes for the production of aroma compounds, such as solid state fermentation (SSF), in which industrial waste can be used as an inert support. The aim of this study was to obtain, through freeze-drying and Capsul® as wall material, powdered aroma compound 6-pentyl-α-pyrone (6-PP) produced by Trichoderma harzianum IOC 4042 by SSF using sugarcane bagasse as support. According to similar studies, day 7 showed the highest yields. About 86.3 ppm of 6-PP was obtained in the powder after freeze drying, corresponding to 31.2% bioaroma retention. By freeze-drying technique using Capsul® as wall material, it was possible to microencapsulate the aroma compound.
