Processes for extraction of sugar from sugar-bearing plant material |
摘要 |
The invention provides processes for the extraction of sugar from sugar-bearing plant material such as sugar cane. Accordingly, in one aspect of the invention, a process for extracting sugar from sugar-bearing plant material comprises contacting the sugar-bearing plant material with an extractant solution comprising water and a surfactant; and separating the extractant solution from the sugar-bearing plant material. One example of a suitable surfactant is a poly(alkylene oxide) polymer such as a poly(propylene oxide) polymer, a poly(ethylene oxide) polymer, or a poly(propylene oxide)/(ethylene oxide) copolymer. |

1. A process for extracting sugar from sugar-bearing plant material, the process comprising:
contacting the sugar-bearing plant material with an extractant solution comprising water, an organic solvent, and a surfactant; and separating the extractant solution from the sugar-bearing plant material, wherein the sugar-bearing plant material is from the grass family, wherein the surfactant is a poly(alkylene oxide) copolymer and has ethylene oxide units in the range of about 5 wt % to about 85 wt % of formula (I): in which each of x and y are greater than zero, and wherein the surfactant is used to increase extraction efficiency. |
