【摘要】：目的系统分析比较秋季大棚栽培淮扬金花菜(秧草)不同刈割茬数可食用嫩芽干粉营养成分。方法 2013年9月份种植的6座秧草大棚,每隔30天机器刈割一次,刈割6次,最后收集成熟期地上部分全草(种子未脱粒和脱粒后)以及干草秸,共计9茬。经低温真空干燥后超微粉碎成干粉。整个过程详细记录样品水分流失情况。采用标准食物营养成分检测方法进行系统的营养成分比较分析。结果前6茬刈割秧草嫩芽干粉中蛋白质含量28.5%,且含有18种氨基酸,9种必需氨基酸,氨基酸模式与人体氨基酸模式接近,限制氨基酸为色氨酸和蛋氨酸;总膳食纤维含量24.6%~28.4%,脂肪含量4.0%~6.0%;含有丰富的维生素、矿物质及微量元素。其中前3茬秧草嫩芽干粉蛋白质含量分别为38.6%、37.9%和35.9%,脂肪含量分别为4.3%、5.1%及5.0%,总膳食纤维含量为25.4%、24.6%和27.2%。结论秋季大棚栽培秧草前6茬刈割的嫩芽干粉含有丰富的营养成分,以高蛋白、高膳食纤维、低脂肪为特征,且相应营养成分及含量不因刈割茬数的增加而发生明显变化。但种子成熟期样品营养素含量急剧下降,均不具直接食用价值。
[Abstract]:Objective to analysis and comparison of autumn greenhouse cultivation Huaiyang burclover (clover) in different cutting the number of edible extrating nutrients. In 2013 September the 6 methods of planting grass seedlings in greenhouses, every 30 days of machine cutting time, cutting 6 times, finally collect maturity on the part of the whole plant (seed threshing and not after threshing) hay and straw, a total of 9 stubble. After low temperature vacuum drying superfine grinding powder. The whole process detailed records of samples. The loss of water using standard nutrition detection method for nutrition system analysis. The results of the first 6 stubble cutting grass bud seedling mow protein powder 28.5%, and contains 18 kinds of amino acids, 9 essential amino acids, amino acids and amino acid pattern close to the human model, limiting amino acid tryptophan and methionine; 24.6%~28.4% total dietary fiber content, fat content is rich in vitamin 4.0%~6.0%, Minerals and trace elements. The first 3 stubble clover shoots powder protein content were 38.6%, 37.9% and 35.9%, the fat content were 4.3%, 5.1% and 5%, the total dietary fiber content was 25.4%, 24.6% and 27.2%. conclusion extrating autumn greenhouse cultivation clover 6 cuttings contains rich nutrients, to high protein, high dietary fiber, low fat and the corresponding characteristics, nutrient composition and content is not due to increased cutting the number of significant changes. But the seed maturity samples of nutrient content declined sharply, did not have the direct consumption value.
