SOLVENT EXTRACTION OF ANTHOCYANINS FROM WINE POMACE

METIVIER, R. P., FRANCIS, F. J., CLYDESDALE, F. M.·1980·Journal of Food Science

Abstract

There is considerable interest in utilization of natural pigment as food colorants, particularly from raw materials in adequate supply, such as wine grape pomace. The rate and degree of extraction of anthocyanins from grape pomace depends upon a number of factors; this research concerned two: solvent (ethanol, methanol, water), and acid (HCl, citric, tartaric, formic, acetic, propionic). Methanol was the best extractant being 20% more effective than ethanol and 73% more effective than water. HCl was most effective with ethanol, but is also very corrosive. Of the organic acids, citric was most effective with methanol and acetic acid with water.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
