The impact of diet on the quality of fresh meat and smoked ham in goat

Abstract

Goat meat contains low amount of saturated fatty acids and cholesterol and it is a healthier alternative compared to other types of red meat. The aim of this study was to investigate the influence of different diets of goats on the basic chemical composition, fatty acids composition, volatile compounds, color and sensory evaluation of fresh meat and smoked ham (m. superficial gluteal). Meat was obtained from goats of Balkan breed, from three different regions (mountain, hilly and plain), 40 animals per region, about 4 years old at slaughter. Statistically significant difference (P LT 0.05) was noted between values of live weight, protein, fat, moisture, ash, fatty acids, volatile compounds and color and sensory characteristics determined in fresh meat of goats from all regions. Two compounds from the group of aromatic hydrocarbons and compounds from the group of phenols were not determined in fresh meat, while they were present in smoked ham. Alfa-linolenic acid (n-3 FA) is found in higher percentage in goat meat from Mountain region, as well as Linolelaidic acid and Linoleic acid. In goat meat from Mountain region presence of volatile substances is lesser than from Hilly and Plain regions. The results suggest that diet has an impact on the quality of goat meat and goat meat products.
