Abstract
Abstract The invention relates to a process for producing a non-caloric citrus albedo bulking agent comprising obtaining albedo from citrus peels to produce albedo particles substantially free of flavedo, water-washing to reduce soluble carbohydrates, constituents, removing alcohol and water, and bitter constituents, removing alcohol and water, and finally milling to the consistency of flour. The citrus albedo bulking agent obtained from this process is especially useful as a partial replacement for high-caloric ingredients such as flour, fat and/or sugar in a food product with at least a one-third reduction in caloric density, more preferably from 50% to 75% or higher. The citrus albedo bulking agent has a water binding capacity of from 10 to 20 grams of water per one gram of the albedo bulking agent.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
96 words
A process for producing a citrus albedo bulking agent which comprises: (a) shaving a citrus peel to obtain albedo particles which are substantially free of flavedo; (b) washing the albedo particles with water prior to autolysis and/or fermentation occurring therein to remove at least 75% of soluble carbohydrates; (c) contacting the water-washed albedo particles with an alcoholic solution to deflavorize and decolorize the albedo and remove additional carbohydrates; (d) removing the water and alcohol from said albedo particles to produce a bland, decolorized citrus albedo bulking agent; and (e) comminuting the dried citrus albedo bulking agent.
Claim 2
Dependent Claim
96 words
A process for producing a citrus albedo bulking agent which comprises: (a) shaving a citrus peel to obtain albedo particles which are substantially free of flavedo; (b) washing the albedo particles with water prior to autolysis and/or fermentation occurring therein to remove at least 75% of soluble carbohydrates; (c) contacting the water-washed albedo particles with an alcoholic solution to deflavorize and decolorize the albedo and remove additional carbohydrates; (d) removing the water and alcohol from said albedo particles to produce a bland, decolorized citrus albedo bulking agent; and (e) comminuting the dried citrus albedo bulking agent.
Claim 3
Dependent Claim
28 words
A process according to claim 1 which further comprises removing water from the water-washed albedo particles by a dewatering procedure prior to the contacting with the alcoholic solution.
Claim 4
Dependent Claim
19 words
A process according to claim 2 wherein the dewatering procedure consists of screw pressing, centrifugation, alcoholic dehydration or sieving.
Claim 5
Dependent Claim
21 words
A process according to claim 1 wherein the alcoholic solution is selected from the group consisting of isopropanol, methanol and ethanol.
Claim 6
Dependent Claim
12 words
A process according to claim 4 wherein the alcoholic solution is isopropanol.
Claim 7
Dependent Claim
19 words
A process according to claim 5 wherein the isopropanol is of a concentration of greater than 70 weight percent.
Claim 8
Dependent Claim
30 words
A process according to claim 1 wherein the contacting of the water-washed albedo particles with the alcoholic solution is accomplished by continuous countercurrent extraction, batch extraction or single column leaching.
Claim 9
Dependent Claim
25 words
A process according to claim 1 wherein the removal of alcohol and water is accomplished by vacuum drying, fluid bed drying or air tray drying.
Claim 10
Dependent Claim
19 words
A process according to claim 1 which further comprises the addition of a calcium compound into the water-washing step.
Claim 11
Dependent Claim
13 words
The process according to claim 9 wherein the calcium compound is calcium oxide.
Claim 12
Dependent Claim
28 words
The process according to claim 10 wherein the calcium oxide is added at a level of from 0.1% to 1% based upon the weight of albedo, wet basis.
Claim 13
Dependent Claim
28 words
A process according to claim 1 wherein the shaved albedo is rapidly further processed after shaving by freezing or treating with sulfur dioxide prior to autolysis or fermentation.
Claim 14
Dependent Claim
25 words
The process according to claim 1 wherein the finely comminuted citrus albedo bulking agent is of an average particle size of 100 microns or less.
Claim 15
Dependent Claim
25 words
The process according to claim 1 wherein the finely comminuted citrus albedo bulking agent is of an average particle size of 50 microns or less.
Claim 16
Dependent Claim
22 words
A process according to claim 1 wherein the citrus peel is selected from the group consisting of orange, lemon, lime and grapefruit.
Claim 17
Dependent Claim
13 words
A process according to claim 1 where the citrus albedo is orange albedo.
Claim 18
Dependent Claim
14 words
The process according to claim 1 wherein said citrus albedo bulking agent is non-caloric.
Claim 19
Dependent Claim
16 words
The product produced by the process of claims 1, 5, 9, 11, 12, 16 or 17.
Claim 20
Dependent Claim
28 words
The product of claim 18 which has a water binding capacity of from 10 to 20 grams of water per one gram of said citrus albedo bulking agent.
