野生解放眉足蟹（Blepharipoda liberate Shen）基本营养成分分析

Analysis of Nutrient Composition in Blepharipoda liberate Shen captured in the Wild

摘要:

解放眉足蟹是一种珍稀的海产品，主产于山东日照。本文首次系统分析了解放眉足蟹的基本营养成分、脂肪酸、氨基酸和胆固醇等理化指标，并对新鲜、煮熟、晒干及冻干样品进行了比较，为其开发利用提供理论基础。结果表明，解放眉足蟹富含粗蛋白和灰分；干样品中氨基酸含量达13.78×10-2 g/g，且8种必需氨基酸达46.23%，必需氨基酸/非必需氨基酸为0.77~0.92，表明氨基酸营养均衡；28种脂肪酸被确定，不饱和脂肪酸含量达到73.90%以上，主要是多不饱和脂肪酸（40.03~49.53%），其次为单不饱和脂肪酸（28.83~37.26%）和饱和脂肪酸（21.64~26.10%）；冻干样品脂肪酸中致动脉硬化指数（AI）和凝血指数（TI）分别为0.93和0.13；鲜样品胆固醇含量为51.54×10-2~61.52×10-2 mg/g，干样品为248.99×10-2~251.15×10-2 mg/g，但差异并不显著。结论：解放眉足蟹是一种营养丰富的海产品，具有很强的开发潜力。

Abstract:

Blepharipoda liberate Shen is a commercially valuable seafood product that is highly popular in Shandong Province. For the first time, the proximate, fatty acid, amino acid, and cholesterol levels in B. liberate Shen were analyzed. B. liberate Shen was found to be rich in crude protein and ash; the content of amino acids in the dried samples was 13.78×10-2 g/g, and the ratio of eight essential amino acid levels was 46.23%, essential amino acids (EAAs)/non-essential amino acids (NEAAs) (0.77~0.92). In total, 28 types of fatty acid were identified and quantified, with monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) constituting approximately 73.90% of all fatty acids; PUFA was dominant (40.03~49.53%), followed by MUFA (28.83~37.26%), and saturated fatty acids (SFA) (21.64~26.10%). The atherogenic index (AI) and thrombogenic index (TI) values (0.93 and 0.13, respectively) were found to be lower in B. liberate Shen compared to other food sources. The content of cholesterol in the fresh and dried samples were 51.54×10-2~61.52×10-2 mg/g and 248.99×10-2~251.15×10-2 mg/g, respectively. These findings confirm that B. liberate Shen is a healthy food source since it has a balance of nutrients with high potential for consumption.
