Claims18
A method for processing fruit material comprising:
- treating the fruit material in a first extraction by immersing the fruit material in water at a temperature of about 20° C. to about 50° C., thereby providing a once-extracted fruit material and a juice extract;
- and
- collecting the juice extract;
- treating the once-extracted fruit material in a second extraction by immersing the once-extracted fruit material in water at a temperature of about 40° C. to about 120° C. under a pressure of about 100 psi to about 1500 psi, thereby providing a twice-extracted fruit material and an anthocyanin-rich extract;
- collecting the anthocyanin-rich extract
- treating the twice-extracted fruit material in a third extraction by immersing the twice-extracted fruit material in water at a temperature of about 100° C. to about 145° C., thereby providing a thrice extracted fruit material and a pectin-rich extract;
- collecting the pectin-rich extract;
- and
- treating the thrice-extracted fruit material in a fourth extraction by immersing the thrice-extracted fruit material in water at a temperature of about 130° C. to about 165° C., thereby providing a four times-extracted fruit material and a proanthocyandin-rich extract;
- and
- collecting the proanthocyandin-rich extract.
