Steam explosion technology is used to pre-treat grapefruit peel, and compare it to the traditional acid-ethanol precipitation method. In this paper, through a single factor experiment, four factors are explored: the material-to-liquid ratio, the pH of the extract, the steam explosion pressure, and the steam explosion pressure maintenance time affect the yield of pectin. Finally, the best process parameters for extracting pectin are determined: material-to-liquid ratio 1:15 g/mL, the pH of the extract is 2, the steam explosion pressure is 0.8Mpa, and the steam explosion pressure maintenance time is the 90s. At this time, the yield of pectin is 17.50%.
