- 摘要:
- 以吉林、黑龙江、辽宁、河北、湖北、新疆、浙江、江西、西藏9个不同产地的黑木耳为试材，采用国标规定方法分析黑木耳中常规营养物质，利用高效液相色谱法分析黑木耳中氨基酸含量，利用电感耦合等离子体质谱仪检测矿物质含量，利用气相色谱法检测脂肪酸含量。以期为研究不同产地黑木耳中营养成分的差异、调节饮食结构、开发黑木耳新产品提供参考依据。结果表明：不同产地黑木耳常规营养成分具有一定的差异性。江西黑木耳灰分、粗脂肪，吉林黑木耳膳食纤维，浙江黑木耳粗蛋白、总糖，辽宁黑木耳粗多糖含量显著高于其他地区（P<0.05）。辽宁和浙江的黑木耳中必需氨基酸含量较高，分别达到41.89、39.20 g·kg-1，占总氨基酸数的45.52%、38.02%；浙江黑木耳中味觉氨基酸、药用氨基酸含量显著高于其他地区。江西黑木耳中铁、钙、锌含量均显著高于其他8个地区（P<0.05）；共检测23种脂肪酸，其中9种饱和脂肪酸和14种不饱和脂肪酸。对营养成分进行相关性及主成分分析发现，灰分、膳食纤维、粗脂肪、粗蛋白、总糖、粗多糖为主要的品质指标，综合评价发现西藏、湖北、吉林黑木耳品质较优。
- Abstract:
- To study the difference of nutritional ingredients in Auricularia heimuer from different places,and provide theoretical support for adjusting dietary structure and developing new products of Auricularia heimuer.In this study,Auricularia heimuer from 9 different places such as Jilin,Heilongjiang,Liaoning,Hebei,Hubei,Xinjiang,Zhejiang,Jiangxi and Tibet were taken as materials.The conventional nutrient ingredients in Auricularia heimuer were analyzed by the national standard method,the amino acid content in Auricularia heimuer was analyzed by high performance liquid chromatography,the mineral content was detected by inductively coupled plasma-mass spectrometry and the fatty acid content was determined by gas chromatography.The results showed that there were some differences in conventional nutrient ingredients in Auricularia heimuer from different places.The ash contents and crude fat of Auricularia heimuer in Jiangxi,dietary fiber of Auricularia heimuer in Jilin,crude protein and total sugar of Auricularia heimuer in Zhejiang and crude polysaccharide of Auricularia heimuer in Liaoning were significantly higher than those in other places (P<0.05).The essential amino acid content of Auricularia heimuer in Liaoning and Zhejiang was higher,reaching 41.89 and 39.20 g·kg-1 respectively,accounting for 45.52% and 38.02% of the total amino acid content.The content of taste amino acid and medicinal amino acid in Auricularia heimuer in Zhejiang was significantly higher than that in other places.The Fe,Ca and Zn contents of Auricularia heimuer in Jiangxi were significantly higher than those in other 8 places (P<0.05);a total of 23 fatty acids were detected,including 9 saturated fatty acids and 14 unsaturated fatty acids.The correlation and principal ingredient analysis of nutritional ingredients showed that ash content,dietary fiber,crude fat,crude protein,total sugar and crude polysaccharide were the main quality indicators.Comprehensive evaluation showed that the quality of Auricularia heimuer was better in Tibet,Hubei and Jilin.
