Abstract

This study contributes new insight into the comparative nutrient profiles of neo-tropical species “agouti (Dasyprocta leporina); nine-banded armadillo (Dasypus novemcinctus): opossum (Didelphis marsupialis) and lowland paca (Cuniculus paca)” compared to domestic species “cattle, veal (Bos taurus); sheep (Ovis aries); goat (Capra aegagrus hircus) and pigs (Sus scrofa domesticus)”. The research aimed to assess the chemical and mineral content present in the livers of these species as there was a growing interest for more sustainable and healthier meat sources. Analysis revealed significant differences in the composition of crude fat, iron, calcium, potassium, sodium, and phosphorus between the neo-tropical and domestic species. Neo-tropical species exhibited higher levels of crude fat, iron, calcium, and potassium, while domestic species showed higher levels of sodium and phosphorus. The results highlighted the potential nutritional advantages of incorporating underutilized neo-tropical offal into human diets, particularly in regions facing micro-nutrient deficiencies, particularly in iron, calcium and potassium.

在特立尼达和多巴哥狩猎的四种精选新热带哺乳动物肝脏的营养价值

本研究对新热带物种刺鼠（Dasyprocta leporina）的营养成分比较有新的认识；九带犰狳（Dasypus novemcintus）：负鼠（Didelphis marsupialis）与低地驼鹿（Cuniculus paca）“比较家养种”牛、小牛肉（Bos taurus）；羊（Ovis aries）；山羊（Capra aegagrus hircus）和猪（Sus scrofa domesticus）”。这项研究旨在评估这些物种肝脏中存在的化学和矿物质含量，因为人们对更可持续、更健康的肉类来源越来越感兴趣。分析显示，新热带和家养物种在粗脂肪、铁、钙、钾、钠和磷的组成上存在显著差异。新热带物种的粗脂肪、铁、钙和钾含量较高，而家养物种的钠和磷含量较高。研究结果强调了将未充分利用的新热带动物内脏纳入人类饮食的潜在营养优势，特别是在面临微量营养素缺乏，特别是铁、钙和钾缺乏的地区。
