Influence of Marination with Aromatic Herbs and Cold Pressed Oils on Black Angus Beef Meat

Beef aging is one of the most common methods used for improving its qualities. The main goal of the present study was to analyse the influence of different cold pressed oils and aromatic herbs during marination process on the nutritional, textural, and sensory attributes of the final grilled sirloin samples. In order to fulfil this goal, methods like GC-MS, HPLC/DAD/ESI-MS, HLPC-RID were performed to quantify fatty acids, phenolic acids, and organic acids, respectively. Textural and sensory analysis were performed with CT 3 Texture Analyser and hedonic test. The results showed high improvement of the meat grilled samples regarding the content of phenolic acids, and textural and sensory characteristics. Pearson values indicate strong positive correlations between raw and grilled samples regarding their content in phenolic acids. Hardness, chewiness, gumminess decreased during marination, meanwhile, resilience, and cohesiveness increased. Sensory analysis highlighted that meat samples marinated with olive oil and rosemary for 120 h reached the highest hedonic score among the tested samples.

Automated summary

The study analyzed the impact of different cold pressed oils and aromatic herbs on the nutritional, textural, and sensory attributes of grilled sirloin samples during marination process. Results showed an increase in phenolic acid content and improvement in sensory characteristics of the meat samples, with those marinated in olive oil and rosemary for 120 hours receiving the highest hedonic score.
