To compare the foreleg meat quality between Gannan Juema pigs and Duroc-Landrace-Yorkshire pigs.
The edible qualities, nutritional quality and antioxidant capacity of the foreleg meat from 8 to 10 month-old of Gannan Juema pigs and Duroc-Landrace-Yorkshire pigs were analyzed.
The a*, shear force, hardness, cohesiveness, protein content, content of histidine, arginine, alanine, proline, valine,linoleic acid, α-linolenic acid, eicosenoic acid, docosenoic acid, arachidonic acid, docosahexaenoic acid, iron element,copper element and zinc element content were significantly higher compared with Duroc-Landrace-Yorkshire pork(P<0.05). Conversely, L*, b*, fat content, aspartic acid, glutamic acid, serine, threonine, methionine, leucine and lysine were significantly lower in Gannan Juema pork (P<0.05). Compared with Duroc-Landrace-Yorkshire pork, Gannan Juema pork exhibited superior color characteristics, compact and tough texture, along with high-protein and low-fat nutritional profiles. Its amino acid composition was closer to the ideal protein pattern recommended by Food and Agriculture Organization of the United Nations/World Health Organization. Moreover, Gannan Juema pork contained lower saturated fatty acids, higher polyunsaturated fatty acids, abundant mineral elements and high antioxidant enzyme activity.
Gannan Juema pork has excellent edible quality, nutritional quality and antioxidant capacity,which meets consumers’ demand for healthy and high-quality meat products and has good market development prospects and promotion value.
