Betaine belongs to the most important nitrogen sub-stances in sugar beet. It is used in a pharmaceutical,
cosmetic, feed, food and chemical industry. Betaine
separation from beet molasses is a difficult process.
Many methods were used but the separation using an
SMB technique seems to be the most effective. This
method was described by Heikkila, Hy€ ooky, and Kuisma
(1992). Beet molasses containing 60% of sucrose and 4.5–5.5% of betaine was divided in a sucrose fraction
containing 80–95% of sucrose and betaine fraction with
25–80% of betaine. Residual molasses contained 15–30%
of sucrose.
A separation of mixtures glucose–fructose, glucose–
fructose–sucrose eventually (e.g. Kishihara et al., 1992)
and further separation of sugar alcohol (sorbitol) and
sugars belong among the realized industrial applica-tions
