| Sumario: |
The general objective of this investigation was to determine the variation of the polarimetric
analysis due to the presence of dextran in cane juice.
The polarimetric method established by the ICUMSA methodology was used in the
investigation,
In the research, pre-harvest cane was used because it has low levels of dextran due to the
cutting conditions and time of exposure to the environment. This non-crystallizable polysaccharide
is synthesized by the lactic acid bacterium Leuconostoc Mesenteroides from sucrose, causing some
production problems such as:
•Increase of viscosity of cane juice, which requires a greater energy expenditure to process
it.
Errors in the estimation of the production when evaluated by the polarimetric method,
since the method is by refraction of light, this rotates the light beam according to the compounds
present in the juice, dextran being a dextrorotatory compound as well as the sucrose, the
measurement is altered. |
