## Abstract

The specification provides methods for extracting juice, anthocyanin, pectin, proanthocyanidin, and/or other phenolic compounds, from fruit material such as cranberry fruit, presscake, and/or pomace, through a sequential extraction procedure.

## Claims

### Claim 1

A method for extracting proanthocyanidin comprising:
(a) treating a fruit material in an extraction with water at a temperature of about 130° C. to about 165° C. and under a pressure of about 100 psi to about 1500 psi, thereby providing an extracted fruit material and a proanthocyanidin-rich extract; and
(b) collecting the proanthocyanidin-rich extract.

### Claim 2 (depends on 1)

The method of claim 1, wherein the method further comprises:
(c) treating the extracted fruit material with water at a temperature of about 145° C. to about 200° C. and under a pressure of about 100 psi to about 1500 psi, thereby providing a phenol-rich extract; and
(d) collecting the phenol-rich extract.

### Claim 3 (depends on 2)

The method of claim 2, wherein step (a) is performed in a vessel, and step (c) is performed in the same vessel.

### Claim 4 (depends on 1)

The method of claim 1, wherein step (a) comprises immersing the fruit material in water.

### Claim 5 (depends on 1)

The method of claim 1, wherein the method further comprises, prior to step (a):
extracting anthocyanins from the fruit material with water at a temperature of about 40° C. to about 120° C. prior to the fruit material's treatment in step (a), thereby providing an anthocyanin-rich extract; and
collecting the anthocyanin-rich extract.

### Claim 6 (depends on 1)

The method of claim 1, wherein the method further comprises, prior to step (a):
extracting pectin from the fruit material with water at a temperature of about 100° C. to about 145° C. and a pressure of about 100 psi to about 1500 psi, thereby providing a pectin-rich extract; and
collecting the pectin-rich extract.

### Claim 7 (depends on 5)

The method of claim 5, wherein the method further comprises, prior to step (a):
extracting pectin from the fruit material with water at a temperature of about 100° C. to about 145° C. prior to the fruit material's treatment in step (a), thereby providing a pectin-rich extract; and
collecting the pectin-rich extract.

### Claim 8 (depends on 7)

The method of claim 7, wherein extracting pectin from the fruit material with water at a temperature of about 100° C. to about 145° C. comprises:
extracting pectin from the fruit material with water at a temperature of about 100° C. to about 145° C. under a pressure of about 100 psi to about 1500 psi, prior to the fruit material's treatment in step (a).

### Claim 9 (depends on 5)

The method of claim 5, wherein the method further comprises:
(c) treating the extracted fruit material with water at a temperature of about 145° C. to about 200° C., thereby providing a phenol-rich extract; and
(d) collecting the phenol-rich extract.

### Claim 10 (depends on 9)

The method of claim 9, step (c) comprises:
treating the extracted fruit material with water at a temperature of about 145° C. to about 200° C. and under a pressure of about 100 psi to about 1500 psi.

### Claim 11 (depends on 1)

The method of claim 1, wherein the method further comprises, prior to step (a):
extracting, in a vessel, at least one of:
juice from the fruit material; and
pectin from the fruit material.

### Claim 12 (depends on 11)

The method of claim 11, wherein step (a) is performed in the vessel.

### Claim 13 (depends on 11)

The method of claim 11, wherein the method further comprises:
extracting, in the vessel, at least one of:
anthocyanin from the fruit material; and
phenols from the fruit material.

### Claim 14 (depends on 13)

The method of claim 13, wherein step (a) is performed in the vessel.

### Claim 15 (depends on 1)

The method of claim 1, wherein the method further comprises:
extracting at least one of:
juice from the fruit material;
pectin from the fruit material;
anthocyanin from the fruit material; and
phenols from the fruit material.

### Claim 16 (depends on 1)

The method of claim 1, wherein step (a) comprises immersing the fruit material in water.
