Studies of Proanthocyanidin Candy Preparations

OBJECTIVE To study new preparations of proanthocyanidin candy. METHODS The standard curve of proanthocyanidin preparations was established by UV spectrophotometry. The formulations and preparation processes of the proanthocyanidin pressed candy preparation, hard candy preparation and soft sweet preparation were studied. The appearance, hardness, dry weight loss, tablet weight and content were used as the inspection indicators, and the relevant quality of proanthocyanidin candy preparation was tested. RESULTS The UV spectrophotometry results investigated that the maximum absorption wave of the procyanidin was at 287 nm. Meanwhile, between the 80-220 μg·mL^-1 of the procyanidin solutiongs possessed a good linear relationship at this wave. The appearance, hardness, loss on drying, tablet weight and content of the various types of candy preparations prepared met the standards. CONCLUSION The proanthocyanidin candy prepared in this study enriches the existing dosage forms.
