摘要：

为了探究干燥工艺对林蛙籽中二十碳五烯酸（EPA）、α-亚麻酸（ALA）、二十二碳六烯酸（DHA）、花生四烯酸（ARA）、二十二碳五烯酸（DPA）、亚油酸（LA）和油酸（OA）含量的影响，本文利用高效液相色谱法（HPLC）对自然干燥、冷冻干燥和热风干燥（40、50、60和80 ℃）后的林蛙籽中七种不饱和脂肪酸含量进行测定。对于不同的干燥方式，林蛙籽中七种不饱和脂肪酸含量为50 ℃热风干燥 >冷冻干燥 >自然干燥。对于热风干燥不同温度，林蛙籽中七种不饱和脂肪酸含量为50 ℃热风干燥 >40 ℃热风干燥 >60 ℃热风干燥 >80 ℃热风干燥。结果表明，不同的干燥工艺会对林蛙籽中七种不饱和脂肪酸含量产生不同程度的影响，50 ℃热风干燥为林蛙籽最佳干燥工艺，其次为冷冻干燥（损失率0.22%~5.64%），然后是40 ℃热风干燥（损失5.15%~7.39%）。本研究为林蛙籽的加工和利用提供了参考依据。

Abstract:

To investigate the effects of drying process on the contents of eicosapentaenoic acid (EPA),α-linolenic acid (ALA),docosahexaenoic acid (DHA),arachidonic acid (ARA),docosapentaenoic acid (DPA),linoleic acid (LA) and oleic acid (OA) in Rana chensinensis ovum,the content of seven unsaturated fatty acids was determined by high performance liquid chromatography(HPLC)after natural drying,freeze drying and hot air drying (40,50,60 and 80 ℃).For different drying methods,the content of seven unsaturated fatty acids in Rana chensinensis ovum was 50 ℃ hot air drying > freeze drying > natural drying.The content of seven unsaturated fatty acids in Rana chensinensis ovum at different temperatures of hot air drying was 50 ℃ hot air drying > 40 ℃ hot air drying > 60 ℃ hot air drying > 80 ℃ hot air drying.The results showed that different drying processes can affect the content of seven unsaturated fatty acids in Rana chensinensis ovum to different degrees,with 50 ℃ hot air drying being the best drying process for Rana chensinensis ovum,followed by freeze drying (loss rate 0.22%-5.64%),and then 40 ℃ hot air drying (loss rate 5.15%-7.39%).This study provided a reference for the processing and utilization of Rana chensinensis ovum.
