Abstract

The chemical extraction of soluble dietary fiber( SDF) from Pitaya Peel was studied by single factor experiment and response surface methodology. The results indicated that the optimal conditions of extracting SDF from Pitaya Peel were as follows: the extraction temperature was 79. 20 ℃,Citric acid concentration was 2. 9%,solid to liquid ratio 1∶ 13. 62,the extraction time was 120. 10 min,SDF yield was 14. 07%.

Key words： pitaya peel; chemical method; soluble dietary fiber; response surface methodology
