Abstract
The invention relates to the use of an ensiling agent comprising an acidifying formate for the treatment of unchopped beets. In addition, the invention relates to methods for sugar and ethanol production from sugar beets. By using the ensiling agent, sugar degradation can be significantly reduced in sugar beets during storage.
Claims21
A method for treating beets to reduce degradation of sugar occurring during storage of the beets, the method comprising:
- treating unchopped beets with an ensiling agent which serves for chemical acidification and
- storing the treated beets under exclusion of air,
- wherein the ensiling agent comprises an acidifying formate, or
- wherein the ensiling agent comprises in addition to ammonium tetraformate and ammonium propionate:
- 5-10 wt -% lactic acid,
- 1-5 wt -% glycerol and
- 0.1-0.5 wt -% formamide.
4 more elements
A method for extraction of sugar from sugar beets, comprising the steps of:
- a. treating unchopped sugar beets with an ensiling agent which serves for chemical acidification,
- b. storing the treated sugar beets under exclusion of air,
- c. chopping the sugar beets,
- d. extracting raw juice from the chopped sugar beets, and
- e. extracting sugar from the raw juice,
- wherein the ensiling agent comprises an acidifying formate, or
- wherein the ensiling agent comprises in addition to ammonium tetraformate and ammonium propionate:
- 5-10 wt -% lactic acid,
- 1-5 wt -% glycerol and
- 0.1- 0.5 wt -% formamide.
7 more elements
A method for production of bioethanol from sugar beets, which comprises the following steps:
- a. treating unchopped sugar beets with an ensiling agent which serves for chemical acidification,

- c. chopping the sugar beets, and
- d. producing ethanol from the chopped sugar beets,
- wherein the ensiling agent comprises an acidifying formate, or
- wherein the ensiling agent comprises in addition to ammonium tetraformate and ammonium propionate:
- 5-10 wt -% lactic acid,
- 1-5 wt -% glycerol and
- 0.1-0.5 wt -% formamide.
