Abstract:

Quadratic orthogonal rotation combination design was used to study the effects of three main technological conditions, including extraction temperature, extraction time and ratio of solvent to solid on extraction yield of water-soluble polysaccharides from apple pomace. Results showed that various extraction conditions affected extraction yield in the following order of extraction temperature > extraction time > ratio of solvent to solid, and a maximum extraction yield of 14. 94% was achieved by the optimal extraction for 4.1 h at 84 ℃ with a ratio of solvent to solid 52:1, which was obtained by frequency analysis.

Key words: apple polysaccharides, quadratic orthogonal rotation combination design, extraction yield
