Abstract:
With different levels of black fungus as materials，its extract was made by hot water extraction method.The polysaccharide content of black fungus was determined，and the effect of temperature，polysaccharide concentration，pH and metal ions on viscosity were studied.The results showed that the black fungus extract polysaccharide content was the highest with 70.30% at pH 6 by heating at 95℃ for 90 min.The black fungus extract polysaccharide content was higher at pH 6~7.The viscosity of black fungus extract increased by Fe2+，while it reduced by K+.
