title: Relationship between refractive index and dry-substance content for lactulose syrups.
abstract: The relationship between the refractive index and the dry substance content of lactulose syrups of different compositions was investigated. It was found that, for a concentration range of 55-75% of dissolved carbohydrates, the sucrose tables can be used after correction by a factor of 0.97.
