Title: EXTRACTION AND ANALYSIS OF SILKWORM EXCREMENT PECTIN
Abstract: The subject how to extract pectin from the silkworm after the extraction of sodium copper chlorophyll is studied. The result indicated that the optimum condition for the extractions were as follows: activated carbon decolorizing time 120 min, precipitation pH=3.5, precipitation temperature 50 ℃, concentrated solution to 95 % alcohol should be 1∶1.1. Analyzing results showed that the pectin is low ester pectin. The mass loss rate, total ash content and pectin production pH all conformed the national standard.
