Studies on microwave extraction of pectin in Pyracantha fortuneana residue which red and yellow pigments had been extracted completely were made with hydrochloric acid, and the qualities of extracted pectin were tested. The single factor test included the pH of extraction solvent, solid-liquid ratio, extraction temperature, microwave watt, extraction time and extraction times. The optimal conditions of extraction technology were discovered by orthogonal test L9(34). Results showed that the optimal conditions of microwave extraction were as fo...
