| Abstract: |
| To explore the extraction technology of polysaccharides from Kaite mango processing wastes，the
optimal extraction parameters were investigated by using orthogonal array design. The contents of polysaccharide
were determinated by anthranone-sulfuric acid. The results showed that the optimum conditions for extracting
polysaccharides in peel were as follows：extraction temperature of 70℃，extraction time for 2 hours，
liquid-to-solid ratio of 1∶25，and re-extracted 3 times. The polysaccharide yield could reach 6.62
（±0.51）% in peel.For the fruit embryo，the optimum extraction technology was as follows：extraction
temperature of 90℃，extraction time for 3 hours，liquid-to-solid ratio of 1∶20 and re-extracted 3 times.
The polysaccharide yield was 3.48（±0.40）%. The polysaccharide content in peel was higher than that in
embryo. These results suggested that extracts of mango processing wastes had potential value of utilization in
polysaccharide industries. |
