Abstract:
1. A method for extracting xyloglucans from fruit, comprising: treating the fruit in a first extraction by advancing the fruit along a path while flowing a first extraction liquid countercurrently to the advancing fruit, wherein the first extraction is performed at a temperature of about 75° F. or less, to thereby provide a juice extract and a once-extracted fruit; treating the once-extracted fruit in a second extraction by advancing the once-extracted fruit along a path while flowing a second extraction liquid countercurrently to the advancing once-extracted fruit, wherein the once-extracted fruit is contacted with pectinase enzymes under conditions sufficient to digest at least a portion of the pectin in the once-extracted fruit, and wherein the second extraction is performed at a temperature of at least about 90° F., to thereby provide a xyloglucan and proanthocyanidin-containing extract and a twice-extracted fruit; treating the xyloglucan and proanthocyanidin-containing extract to remove at least a portion of the proanthocyanidins from the extract, to thereby provide a xyloglucan-enriched extract; and collecting the xyloglucan-enriched extract.
