Background: This study evaluated the acceptability (by sensorial and visual analyses) of meat from 40 Nellore heifers (finished in feedlots for 73 days) fed with different diets supplemented with essential oils (EOs) and an active principle blend. The five diets tested were: CON - a diet without essential oil and active principle blend (eugenol, thymol, and vanillin); ROS - a diet supplemented with rosemary EO; BLE - supplemented with a blend; BCL - a diet with clove EO+ blend; and BRC - a diet with rosemary, clove EOs + blend. The acceptability of diet and aging time was evaluated by consumers.
Results: Diet affected consumer acceptability and visual analysis (meat color). The diets with EO and the blend showed better sensory acceptance by the consumers; meat aged for 7 days received higher scores than meat aged for 1 day. Meat from heifers that received both EOs + blend (BCL, BRC) obtained the highest scores in the visual evaluation.
Conclusion: The use of natural compounds in ruminant diets improves the sensory characteristics of meat without damaging visual acceptability and may be an alternative to the conventional additive market. © 2020 Society of Chemical Industry.
