古田银耳主栽品种基本营养分析与评价
目的 比较福建省古田县银耳主栽品种黄色银耳(Tr01)、白色银耳(Tr21)间的营养差异。方法 采集同一栽培模式下的2种银耳, 分析了2种银耳的水分、蛋白质、灰分、膳食纤维、维生素、矿物质元素含量及氨基酸组成, 结合统计学和FAO/WHO氨基酸评估模式对二者营养进行全面比较。结果 以干样计算, Tr01中的蛋白质、灰分、膳食纤维、维生素B2、K含量均高于Tr21; Tr01中的碳水化合物、维生素C、Ca含量低于Tr21, 差异显著(P0.05)。氨基酸分析及评价结果表明, Tr01的呈味类氨基酸、酸味类氨基酸、甜味类氨基酸、苦味类氨基酸、含硫氨基酸、支链氨基酸、芳香氨基酸含量均低于Tr21; Tr01的必需氨基酸含量及支芳值高于Tr21, 差异显著(P<0.05)。Met+Cys是2种银耳的第一限制性氨基酸。Tr01氨基酸比值系数分明显低于Tr21, 表明Tr21氨基酸营养价值高于Tr01。结论 2种银耳营养价值存在明显的营养价值特异性。
Objective To compare the differences between major cultivars of Tremella fuciformis (yellow tremella (Tr01) and white tremella (Tr21) in Gutian, Fujian province. Methods The 2 speciesspecies of Tremella fuciformis in the same cultivation mode were collected, and the content of water, protein, ash, dietary fiber, vitamins, mineral elements and amino acid composition of 2 speciesspecies of Tremella fuciformis were analyzed. Comprehensive comparison of nutrition between them was conducted by combining statistics and FAO/WHO amino acid assessment models. Results Calculated on a dry basis, the content of protein, ash, dietary fiber, vitamin B2 and K in Tr01 was higher than Tr21; the content of carbohydrate, vitamin C and Ca in Tr01 was lower than that in Tr21, and the difference was significant (P0.05). There was no significant difference between the 2 groups in fat and iron. Results of amino acid analysis showed that FAA, SOAA, SWAA, BIAA, SAA, BCAA, AAA in Tr01 were lower than those in Tr21. The essential amino acid content and branching value of Tr01 were higher than Tr21, and the difference was significant (P<0.05). Met+Cys was the first limiting amino acid of 2 species of Tremella fuciformis. The amino acid ratio coefficient of Tr01 was significantly lower than that of Tr21, which indicated that the nutritional value of Tr21 amino acid was higher than Tr01. Conclusion The nutritional value of the 2 species of Tremella fuciformis has significant nutritional value specificity.
