摘要
【目的】为了比较不同产地金佛山方竹(Chimonobambusa utilis)竹笋营养成分,为金佛山方竹综合利用提供参考。【方法】笔者对贵州桐梓县、云南镇雄县、重庆南川区、贵州正安县、贵州绥阳县5个不同产地金佛山方竹竹笋各营养成分进行测定,用方差分析和Duncan极差分析等方法分析不同产地竹笋各营养成分的稳定性。【结果】5个不同产地金佛山方竹竹笋各营养成分差异性显著,且各产地竹笋营养含量各具特点。桐梓金佛山方竹竹笋具有最高的灰分、膳食纤维,较高的蛋白质、水分和较低的脂肪;镇雄金佛山方竹竹笋具有最高的蛋白质,较高的灰分和膳食纤维;南川金佛山方竹竹笋具有最高的还原糖;正安金佛山方竹竹笋具有最高的水分和最低的脂肪;绥阳金佛山方竹竹笋具有较高的还原糖和灰分。桐梓金佛山方竹竹笋具有最高的钾含量和较高的磷含量;镇雄金佛山方竹竹笋具有最高的磷含量、铜含量、钙含量、镁含量、锌含量,较高的铁含量和锰含量;南川金佛山方竹竹笋具有最高的铁含量和锰含量,较高的锌含量、钙含量、铜含量;正安金佛山方竹竹笋具有较高的镁含量;绥阳金佛山方竹竹笋具有较高的钾含量。5个不同产地金佛山方竹竹笋蛋白质含量均高于其他28个竹种。【结论】该文结果为各产地进一步培育优良笋用竹、功能笋用竹类型提供参考。
【Objective】In order to compare the nutrient composition of bamboo shoots from 5 different habitats of Chimonobambusa utilis,provide reference for the comprehensive utilization of this bamboo spieces.【Method】Determine the nutrient composition of Ch.utilis shoots from Tongzi County,Guizhou Province,Zhenxiong County,Yunnan Province,Nanchuan District,Chongqing,Zheng′an County,Guizhou Province and Suiyang County,Guizhou Province.The stability of bamboo′s nutrient composition from different habitats was analyzed by means of variance analysis and Duncan range analysis.【Result】The results showed that the nutrient contents of Ch.utilis shoots from five different habitats were significantly different,and the nutrient contents from different habitats had their own characteristics.The shoots of Ch.utilis from Tongzi have the highest ash content,dietary fiber,higher protein,water content and lower fat.Shoot from Zhenxiong had the highest protein,higher ash content and dietary fiber.Shoot from Nanchuan had the highest reducing sugar.Shoot from Zheng′an had the highest moisture content and the lowest fat content.Shoot from Suiyang had higher reducing sugar and ash content.Shoot from Tongzi had the highest potassium content and higher phosphorus content.Shoot from Zhenxiong had the highest content of phosphorus,copper,calcium,magnesium,zinc,and higher content of iron and manganese.Shoot from Nanchuan had the highest iron content,manganese content,zinc content,calcium content and copper content.Shoot from Zheng′an had high magnesium content,and from Suiyang have high potassium content.The protein content of bamboo shoots of Ch.utilis from 5 different habitats was higher than those of the other 28 bamboo species.【Conclusion】The results of this paper provide a reference for further cultivation of fine bamboo shoots and functional bamboo shoots in various producing areas.
