Fatty Acid Indices and the Nutritional Properties of Karakul Sheep Meat

Abstract

This study aimed to evaluate the fatty acid profile and health lipid indices of sheep meat (from 52 Karakul sheep from NE Romania). The effect of age at slaughter and the influence of muscle region were studied for nutritional parameters, especially the fatty acids from lipid fractions. Based on the fatty acid profiles and lipid contents, the sanogenic indices were determined for two sheep muscle groups. Thus, two different muscle regions from lamb and adult sheep were analysed from both genders, the Longissimus dorsi and Triceps brachii, to argue the advantages of each category and the rationalization, in terms of meat consumption, regarding their impact on human health. Sheep meat has many components with beneficial effects on human health. Apart from the fact that it is an important source of nutrients due to its high content of proteins, lipids, and minerals, it is also a product that can provide fundamental bioactive compounds for maintaining metabolic functions. The qualitative indices assessment revealed that lambs have meat with high PUFA content on Longissimus dorsi muscles (approx. 25% of total fatty acids), 0.68 for PUFA/SFA, with highest values for n-3 (approx. 8%) and n-6 (approx. 14%). Appropriate values can also be observed in Triceps brachii muscles from adult sheep. The sanogenic indices also presented good values for Longissimus dorsi from lambs and Triceps brachii from adult sheep (polyunsaturation index = 7.2–10.2; atherogenic index = 0.56–0.67; thrombogenic index = 0.78–0.96; hypocholesterolemic/hypercholesterolemic index = 2.4–2.7 (for Longissimus dorsi)).

The Characterization of Subcutaneous Adipose Tissue in Sunit Sheep at Different Growth Stages: A Comprehensive Analysis of the Morphology, Fatty Acid Profile, and Metabolite Profile

“…FAs, as a crucial constituent of adipose tissue, contribute to flavor, nutritional value, and physiological function [29,30]. According to the results we obtained from the fatty acids analyzed in this study, C16:0, 9c-C18:1, and C18:0 were the most abundant in the SAT.…”

Lambs supplemented with Amazonian oilseed co-products: Meat quality and fatty acid profile

“…The smaller values of AI present a greater protective potential for coronary artery diasese. however, the AI was below the recommended value meat (1.0) [ 65 ], but they were better than the average found [ 66 ], who observed an average value of 0.56.…”

The Influence of Sensory Characteristics of Game Meat on Consumer Neuroperception: A Narrative Review

“…Thus, in the specialized literature, the superior value of game meat is confirmed by a higher content of some essential amino acids. Various studies reported comparative data regarding the higher values of the total proteins of game meat and of domestic farm species [ 77 , 98 ]. Accordingly, Okuskhanova et al [ 76 ] revealed that maral meat has a higher content in essential amino acids compared to beef.…”
