Abstract
One-vial vitamins was added to 12 different formuras being prepared by mixing a basic solution of hyperalimentation with 4 kind of fat emulsions and 3 kind of amino acid injections. Stability of vitamins, change of pH and diameters of fat particles in the mixtures were examined at room temperature with non-blocked or blocked light and at a cool dark place.
In case of most of the mixtures without one-vial vitamins their particle size became above 10μm at room temperature after 24hrs or at the cool dark place after 96hrs.However, no change in diameters of the fat particles in many of the mixtures was noted when one-vial vitamins was added.As a result of vitamin analysis in the mixtures, residual rate of B2, K1 and A was found to be above 90% when the mixtures were kept at room temperature with nonblocked light (500Lux) for 24hrs.No decrease of B1, B6, FA and E contents was observed in the mixtures.
