Abstract
|
|
|
|
Bamboo salt chemical properties and in vivo gastric protective effects were evaluated. Scanning electron microscopy revealed the diameter of 9× bamboo salt was approximately 5 μm, the smallest of all samples. The Ca, Mg, Fe, Mn, P, S, and K levels of bamboo salts were higher than for common salts. X-ray diffraction and X-ray photoelectron spectroscopy analyses showed bamboo salts had a complex structure composed of NaCl, KCl, and MgCl2. Bamboo salt structure complexity increased with increased baking times. Purified, solar, and 1× bamboo salt inhibited gastric injury by 19.3%, 28.0%, and 77.8% in Sprague-Dawley (SD) rats, respectively. The 9× bamboo salt showed a high rate of gastric injury inhibition (98.7%). The effect of omeprazole was 99.3%. Bamboo salts reduced gastric secretion and increased gastric juice pH by increased mineral and phytochemical contents, and increased antioxidant activities. Bamboo salt can be used as a functional food to protect against gastric injury.
