| 摘要 | The pretreatment or treatment of sugar beet cossettes with an effective amount of ethylene increases sugar recovery up to 3 with up to 10 percent increase in purity of sugar. Ethylene treatment has also enabled a 125 percent increase in diffuser speed. | ||||||
| 权利要求 | 1. A METHOD OF STIMULATING SUGAR DIFFUSION FROM PLANT TISSUES CONTAINING SUGAR SELECTED FROM THE GROUP CONSISTING OF SUGAR BEETS, SUGAR CANE, SUGAR MAIZE AND SUGAR SORGHUM WHICH COMPRICES CONTACTING THE PLANT TISSUES WITH DIFFUSION WATER IN THE PRESENCE OF ETHYLENE. 2. The method of claim 1 wherein ethylene gas is bubbled through the diffusion water in contact with the plant tissue. 3. The method of claim 1 wherein the ethylene is present in an amount effective to increase sugar extraction efficiency. 4. The method of claim 1 wherein the ethylene is present in the diffusion water in an amount on the order of at least about 0.03 ppm ethylene. 5. The method of claim 1 wherein the ethylene is present in the diffusion water in an amount on the order of from about 0.03 ppm to about 0.21 ppm ethylene. 6. The method of claim 1 wherein the ethylene is present in the diffusion water in an amount of at least about 0.10 ppm ethylene. 7. The method of claim 1 wherein the ethylene is present in an amount equivalent to at least about 0.06 cc ethylene per minute per gram of plant tissue. 8. The method of claim 1 wherein the ethylene is present in an amount equivalent to at least about 0.6 cc ethylene per minute per gram plant tissue. 9. The method of claim 1 wherein the plant tissues are pretreated with ethylene prior to contact with diffusion water. 10. The method of claim 1 wherein the diffusion water is maintained at a temperature of not more than about 80*C. 11. A method of treating sugar beets to increase the amount and purity of sugar recovered therefrom in a diffuser which comprises the steps of passing sugar beet cossettes through a diffuser countercurrent to diffusion water and introducing ethylene into the diffuser. 12. The method of claim 11 wherein the ethylene is bubbled into the diffusion water. 13. The method of claim 11 wherein the cossettes are pretreated with ethylene before introduction into the diffuser. 14. The method of claim 11 wherein the ethylene is present in an amount effective to increase sugar extraction efficiency. 15. The method of claim 11 wherein the ethylene is present in the diffusion water in an amount on the order of at least about 0.03 ppm ethylene. 16. The method of claim 11 wherein the ethylene is present in the diffusion water in an amount on the order of from about 0.03 ppm to 0.21 ppm ethylene. 17. The method of claim 11 wherein the ethylene is present in the diffusion water in an amount of at least about 0.10 ppm ethylene. 18. The method of claim 11 wherein the ethylene is introduced into the diffuser at a rate of at least about 0.06 cc ethylene per minute per gram of sugar beets in the diffuser. 19. The method of claim 11 wherein the ethylene is introduced into the diffuser at a rate of at least about 0.6 cc ethylene per minute per gram of sugar beets in the diffuser. 20. The method of claim 11 wherein the diffusion water is maintained at a temperature of not greater than about 80*C. |
