| Objective: To optimize the extraction of pectin from citrus peel as an agricultural waste by simultaneous hydrolysis
with hydrochloric acid. Methods: The optimized extracting conditions were determined by single-factor and orthogonal test with absorbance
and pectin yield as evaluation index. The effects of key factors includin g extraction time, temperature, pH value, alcohol amount
and ratio of solid to liquid on the extraction rate of pectin were explored by orthogonal experimental design, respectively. Results: The
optimal extraction conditions for extracting pectin from citrus peel were extraction time 2 hour, temperature80℃, solid-to-liquid ratio
(g/mL) 1:15, pH 1.5, 70% ethanol amount. Under the optimal extraction conditions, the predicted maximum yield of pectin was 11.82%.
Conclusion: Each tested physical and chemical index of obtained pectin reached or even exceeded the requirements of the national standards. |
