Comparison of Bamboo Shoot Nutrients of Dendrocalamus brandisii among Different Provenances
摘要
Abstract
Dendrocalamus brandisii is a kind of famous shoot bamboo.Researches on D.brandisii are mostly focused on the analysis of their nutrient components while the differences of nutrient components between provenances are neglected.D.brandisii shoots were selected as materials in this study,which was obtained separately from Simao,Longchuan,Cangyuan and Shiping County,Yunnan Province.Nutritional constituents of bamboo samples were also determined and compared.The results revealed that the moisture contents of D.brandisii shoots of different provenances were high,among which Simao bamboo shoots had the highest moisture content (94％),the lowest content of crude fiber (0.63％),the highest content of total sugar (1.54％),and the lowest tannin content (0.08 mg· 100 g-1).Therefore,the shoots of Simao provenance tasted better.Longchuan bamboo shoots had the highest essential amino acid content (0.68％) and protein content (2.13％).The levels of aspartic acid,glutamic acid and glycine that affect flavor were also the highest among the four geographic provenances,followed by the Simao provenance.Therefore,the shoot flavor of Longchuan and Simao were better than the other two provenances.This indicated that the bamboo provenances from Simao and Longchuan were more suitable for popularization than that from Cangyuan and Shiping.关键词
