The shoulder, loin and leg from P-class pork carcasses were used to determine the nutrient composition of both raw and cooked cuts. Significantly lower fat content were observed in the current study for the leg (5.21g/100g) and loin (6.99g/100g) compared to the shoulder cut (10.32g/100g). The overall percentage fat for all three cuts was less than 10% which is recommended by the South African Heart Mark. The cooked loin cut contained the most protein (27.50g/100g) of the three cooked cuts. When compared to other meat products (beef, mutton and chicken) it is clear that pork is a good source of B vitamins, especially vitamin B3. The cooked loin cut contained the least vitamin B1 (0.22mg/100g), B2 (0.02mg/100g) but the most vitamin B3 (7.09mg/100g), of the three cooked cuts. The 100g cooked shoulder, loin and leg cuts provide on average 40.11% protein, 5.19% magnesium, 3.37% calcium, 24.29% phosphorus, 18.22% zinc, 22.33% iron and 22.50% vitamin B1, 2.57% vitamin B2 and 42.6% vitamin B3 of Recommended Daily Allowances for males, age 25-50. Energy from a 100g portion provides 5.81% of the Recommended Daily Allowances. To conclude, the pork cuts are undoubtedly a good source of nutrients that is required for good health because it is high in protein, have a low fat content and are a nutrient-packed choice for the family and compares favourably with the fat, energy, and cholesterol content of many other meats and poultry.
本研究中,P 级猪肉的肩部、腰部和腿部用于确定生肉和熟肉的营养成分。与肩部(10.32g/100g)和腰部(6.99g/100g)相比,腿部的脂肪含量明显较低(5.21g/100g)。所有三个部位的总脂肪含量均低于南非心脏标志建议的 10%。三个熟肉部位中,熟腰肉的蛋白质含量最高(27.50g/100g)。与其他肉类产品(牛肉、羊肉和鸡肉)相比,猪肉显然是 B 族维生素的良好来源,尤其是维生素 B3。熟腰肉的维生素 B1(0.22mg/100g)、B2(0.02mg/100g)含量最低,但维生素 B3(7.09mg/100g)含量最高。三个熟肉部位中,100g 熟肩肉、腰肉和腿肉平均提供 40.11%的蛋白质、5.19%的镁、3.37%的钙、24.29%的磷、18.22%的锌、22.33%的铁和 22.50%的维生素 B1、2.57%的维生素 B2 和 42.6%的维生素 B3,男性(25-50 岁)每日推荐摄入量为 100g。100g 部分提供的能量占每日推荐摄入量的 5.81%。总之,这些猪肉无疑是健康所需营养物质的良好来源,因为它们富含蛋白质,脂肪含量低,是家庭营养丰富的选择,并且与许多其他肉类和家禽的脂肪、能量和胆固醇含量相比具有优势。
