Abstract: Acid-extraction of pectin from soybean hull was studied. The effects of temperature, pH, ratios of soybean hull to extraction solvent, extraction time on the yields of soybean hull pectin prepared were measured. The results showed that the optimum conditions were: extraction temperature 85℃, pH1.5 and ratios of soybean hull to extraction solvent 1:8, extraction time 30min.

Key words: soy hull, pectin, acid-extraction
