Sensory training and characterization of fish burger formulations made with filleting byproducts of tilapia (Oreochromis niloticus)

Resumo

The objectives of the present study were to train a sensory panel and to conduct the sensory characterization of three fish burger formulations. They were made with filleting byproducts of tilapia (Oreochromis niloticus), for inclusion in school meals. Initially, training of the assessors was conducted using the descriptive method for five attributes of the product: fish odor, hardness, juiciness, fish flavor and condiment flavor. The assessors had good repeatability and were able to discriminate the samples.  After the training, the panelists evaluated the five attributes of the three developed formulations containing different condiments in the fish burger base formulation: C1) 0.3% oregano, C2) 0.05% basil and C3) 0.05% rosemary. This evaluation was followed by acceptance test and purchase intention. The three formulations had mild fish odor and flavor, in addition to a mild condiment flavor. Additionally, the products had good sensory acceptance and purchase intention.
