Claim:
1. A method for extracting xyloglucans from fruit, comprising: treating the fruit in a first extraction in a tank by bathing the fruit in a first extraction liquid, wherein the first extraction is performed at a temperature of about 75° F. or less; collecting the first extraction liquid to thereby provide a juice extract and a once-extracted fruit; treating the once-extracted fruit in a second extraction in a tank by bathing the once-extracted fruit in a second extraction liquid, 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.; collecting the second extraction liquid 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.
