  • Fat substitutes containing water soluble beta-carotene
    Patent number: 5532009
    Abstract: The present invention relates to non-absorbable, non-digestible fat compositions fortified with a water soluble carotenoid/cyclodextrin complex. The compositions are useful as fat substitutes in food and pharmaceutical compositions. The carotenoid is readily bioavailable and resists partitioning into the fat/fat-like phase.

  • Liquid chromatographic determination of water
    Patent number: 4970170
    Abstract: A sensitive method for the determination of water in the presence of common interferences is presented. The detection system is based on the effect of water on the equilibrium which results from the reaction aryl aldehydes, such as cinnamaldehyde and methanol in the eluent to form cinnamaldehyde dimethylacetal, plus water. This equilibrium is shifted in a catalytic atmosphere of a hydrogen ion form past column reactor. The extent of the shift and the resulting change in absorbance are proportional to the amount of water present.
