Claims22
A method for processing 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 once-extracted fruit and a juice extract;
- and
- treating the once-extracted fruit in a second extraction by advancing the fruit along a path while flowing a second extraction liquid countercurrently to the advancing fruit, wherein the second extraction is performed at a temperature of at least about 90° F., to thereby provide a proanthocyanidin-containing extract and twice-extracted fruit.
A method for processing 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 once-extracted fruit;
- treating the once-extracted fruit in a second extraction in a tank by bathing the fruit in a second extraction liquid, wherein the second extraction is performed at a temperature of at least about 90° F.;
- and
- collecting the second extraction liquid to thereby provide a proanthocyanidin-containing extract and twice-extracted fruit.
