Four species of African giant land snails (Archachatina marginata (ovum) Pfeiffer, Archachatina marginata (saturalis) Philippi, Achatina achatina and Limicolaria spp.) were assessed for their proximate and mineral compositions aimed at establishing their nutritive values on wet weight basis. Analysis of muscle revealed that composition of crude protein varied from 18.66%+/-0.57% in Limicolaria spp. and 20.56%+/-0.05% in Archachatina marginata (ovum) Pfeiffer; moisture content was 76.56%+/-0.04% in Archachatina marginata (ovum) Pfeiffer and 78.68%+/-0.68% in Limicolaria spp. and ash was 1.34%+/-0.02% in Achatina achatina and 1.44%+/-0.01% in Archachatina marginata (ovum) Pfeiffer. These values were statistically different from each other (P<0.05). Carbohydrate and fat content were generally low. Crude fibre was not detected in any of the species. The concentrations of zinc, iron, manganese, magnesium, calcium, phosphorus, sulphur, potassium and sodium in the flesh of the snails were determined. Values of iron, magnesium, calcium, phosphorus, potassium and sodium were consistently high while cobalt, copper and lead were not detected. Snails complement the required trace and minor elements needed for proper growth and development in human being, so it is recommended for regular consumption.
对四种非洲巨型陆地蜗牛（带边玛瑙螺（卵） Pfeiffer、带边玛瑙螺（饱和型） Philippi、非洲大蜗牛和 Limicolaria 属）进行了近似成分和矿物质成分评估，旨在确定其以湿重计的营养价值。肌肉分析表明，粗蛋白含量在 Limicolaria 属中为 18.66%±0.57%，在带边玛瑙螺（卵） Pfeiffer 中为 20.56%±0.05%；带边玛瑙螺（卵） Pfeiffer 的水分含量为 76.56%±0.04%，Limicolaria 属为 78.68%±0.68%，非洲大蜗牛的灰分为 1.34%±0.02%，带边玛瑙螺（卵） Pfeiffer 为 1.44%±0.01%。这些值在统计学上彼此不同（P<0.05）。碳水化合物和脂肪含量普遍较低。在任何一个物种中均未检测到粗纤维。测定了蜗牛肉中锌、铁、锰、镁、钙、磷、硫、钾和钠的浓度。铁、镁、钙、磷、钾和钠的值一直较高，而未检测到钴、铜和铅。蜗牛补充了人体正常生长发育所需的必需微量元素和少量元素，因此建议经常食用。
