Nutrition and Nutraceutical of Bambusa burmanica Gamble and Thysostachys siamensis Gamble shoots

Abstract

The nutrition and nutraceutical of Bambusa burmanica Gamble and Thysostachys siamensis Gamble were evaluated by proximate analysis, amino acid, phytosterol and total phenolic contents. The results showed that 2 species of bamboo shoots contains about 91-92% moisture content, 1-3.44% protein, 0.06-0.13% fat, and 2.23-2.60% dietary fiber. The 18 free amino acids (included 8 essential amino acids) and phytosterol (campesterol, stigmasterol, β-sitosterol and brassicasterol) were found in both of bamboo shoots. Bambusa burmanica Gamble had total free amino acids and total phytosterol more than Thysostachys siamensis Gamble. In the other hand, the Thysostachys siamensis Gamble had total phenolic compounds and DPPH radical-scavenging activity more than one. The boiling procedure had effect on nutrition and nutraceutical of 2 species bamboo shoots. After boiling, protein, ash and carbohydrate content were decreased but lipid and crude fiber content were increased. However 2 species bamboo shoots were good source of quality protein, low fat and high fiber furthermore they had phytosterol and phenolic compounds that suitable to be a health food.
