초록

Extraction of purified plant anthocyanin colors particularly from dark grapes by treating impure materials to insure discrete monomeric anthocyanin molecules in solution and then passing the solution through ultrafiltration membranes to retain soluble and/or cloudy macromolecular, e.g., colloidal, impurities upstream that produce, an aging, haze and sediments, and pass the monomeric anthocyanins downstream for further concentration as liquid or powder to give a stable color concentrate that can be used as a color additive. For example, fruit solids may b...

청구항

In a process for separating anthocyanin components from macromolecular components such as proteins, tannins, pectins and complexes thereof, the improvement comprising ultrafiltering a 500 to 2,000 ppm sulfur dioxide aqueous solution of said components through a membrane that passes said anthocyanins and retains said macromolecular components, whereby said anthocyanins are maintained in a discrete monomeric state in said sulfur dioxide solution and substantially separated from said macromolecular components in a single step process.
