2011年11、12月和2012年1、2、3、4月采集毛竹冬笋、春笋,对其水分、总糖、氮、磷、钾、粗蛋白、17种氨基酸等含量进行测试分析。结果表明:毛竹笋的水分含量为88.9～92.8 g/100g,总糖含量为1.3～2.4 g/100g,氮含量为0.34～0.52 g/100g,钾含量为0.30～0.58 g/100g,磷含量为0.041～0.090 g/100g,粗蛋白含量为2.17～3.98g/100g,氨基酸总量变动范围是2.15～3.24 g/100g;毛竹笋中氮、磷、钾、粗蛋白、氨基酸总量的各个月变化基本一致,从11月到次年3月的变化差异不大,但4月则明显下降;毛竹笋水分含量的变化则随着气温升高而增加的趋势;毛竹笋总糖的含量各个月变化不显著;在毛竹笋未出土和已出土的对比试验中,其营养成分含量没有发现显著变化;在氨基酸检测中,除胱氨酸未检出及色氨酸不能检出外,均含有其它16种基本氨基酸,其中天门冬氨酸、脯氨酸、丝氨酸含量的变化规律相似,11月、12月、1月、2月、3月的含量变化不大,而4月急剧下降,酪氨酸含量的变化正好相反,酪氨酸是唯一在4月含量急剧上升的,除了上述4种氨基酸以外,其它已检出的12种氨基酸含量的变化不明显。
The bamboo shoots and bamboo shoots were collected in November, December and January, 2012, January, February, March and April in 2012, and their contents of moisture, total sugar, nitrogen, phosphorus, potassium, crude protein and 17 kinds of amino acids were tested. The results showed that the moisture content of bamboo shoots was 88.9-92.8 g / 100g, the total sugar content was 1.3-2.4 g / 100g, the nitrogen content was 0.34-0.52 g / 100g, the potassium content was 0.30-0.58 g / 100g, and the phosphorus content was 0.041 ~ 0.090 g / 100g, crude protein content was 2.17 ~ 3.98g / 100g, total amino acid content was 2.15 ~ 3.24 g / 100g; bamboo shoots of nitrogen, phosphorus, potassium, crude protein, amino acid total monthly changes Basically the same, from November to March next year, the difference was not significant, but in April decreased significantly; bamboo hair moisture content changes with the temperature increase and trend; bamboo hair content of total sugar changes month by month No significant difference in bamboo shoots unearthed and unearthed contrast test, the nutritional content of the ingredients found no significant change in the amino acid detection, in addition to cystine not detected and tryptophan can not be detected, they contain other 16 The contents of aspartic acid, proline and serine in the three kinds of basic amino acids were similar, and the contents in November, December, January, February and March changed little, but dropped sharply in April. The contents of tyrosine The change in content is just the opposite, tyrosine is the only sharp increase in April content, in addition to the above 4 Other than acid, amino acid changes have been detected in the other 12 kinds of inconspicuous.
