Study on the Mould-Resistant Properties of Moso Bamboo Treated with High Pressure and Amylase
Starch of moso bamboo mainly exists in the elongated parenchyma cells, and it is difficult for amylase to enter moso bamboo and dissolve the starch. Therefore, the mould resistance capability of moso bamboo’s products cannot meet the need for bamboo to resist fungal decay. In this experiment, moso b...

In this experiment, moso bamboo blocks were first treated at six levels of pressure and for six different treatment durations.
