Nutrient Analysis of Chimonobambusa utilis Shoots from Five Different Habitats

【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.
