1. The contents of pentosan, protein, wet gluten, Zeleny volume and 1000 kernel weight of 77 winter wheat varieties planted in north China were investigated.

2. Fig. 2 : Flow chart of pentosan analysis - titration method ( volumetric method ).

3. Fig. 1 Flow chart of pentosan analysis - gravimetric method.

4. Wheat bran water insoluble pentosan has negative influence on dough and bread-making properties.

5. Lignin and pentosan content decrease from pith to bark. and level off after 10 to 12 years old.

6. Fig. 3 Flow chart of pentosan analysis - aniline acetate colorimetric method.

7. Based on phytic acid content and pentosan content, 18 varieties is classified into 4 categories. We think Yumai 47 is an ideal variety for feeding wheat in all tested varieties.

8. Wheat flour water soluble pentosan has little influence on dough and bread-making quality.

9. The technology can simultaneously produce pentosan and dietary fiber, also can only produce pentosan or dietary fiber according to market demands, and is flexible.

10. Fig . 4 Flow chart of pentosan analysis - Orcinol spectrophotometric method.

11. The average contents of starch, amylose, pentosan and lipids in noodle flour were 75.19%, 22.73%, 3.79% and 1.59% respectively with notable diversity between different noodle flours.

11.

12. Wheat pentosan is an important factor affecting the flour processing and food quality.

13. Steamed bun flour, noodle flour and bread flour were used as materials for investigating their contents of starch, amylose, pentosan and lipids.

14. The orcinol-hydrochloric acid method for determining the content of pentosan in wheat was studied in this paper so as to provide a theoretical basis for utilizing wheat in animal feed.

15. Results show that sawdust of black wattle branches which contains more protein, lignin. pentosan, starch, P and Ca etc. than the ordinary mixed sawdust is a good substrate.

16. The method of phloroglucinol to determine the content of wheat pentosan was discussed as well.

17. By using 30 kinds of nullitetrasomics derived from Triticum aestivum "Chinese Spring" as tested materials, the genetic analysis and identification of pentosan content were conducted.

18. In the last 50 years, a large number of studies have been performed on pentosan for its potential broad applications in making bread and other health products.

19. The path analysis showed that the coefficient of direct path and genetic correlation was equivalent between grains number per spike and water soluble pentosan content.

20. There is a significant correlation between phytic acid content and protein content, but a negative significant correlation between phytic acid content and pentosan content.
