Microcrystalline cellulose (MCC) was prepared from Oolong tea waste by acid hydrolysis in the present study. Based on the single factor experiment results, the hydrolysis conditions were optimized by an orthogonal L9(3)4 experiment. Results showed that the degree of polymerization (DP) and yield of MCC were strongly influenced by the time and temperature of hydrolysis, the concentration of HCl and...
Trapa (Trapaceae) is one of the most common aquatic plants. In order to make full use of the resource of Trapa, we investigated two Trapa cultivated species (Trapa quadrispinosa Roxb. and Trapa bispinosa Roxb.) and one Trapa wild species (Trapa pseudoinisa Nakai) popularly found in South China.
