Abstract

Abstract Fresh citrus pulp is water washed and/or combined with an inorganic basic material such as calcium oxide in order to raise the pH of the pulp material to about 4.0 or above. The pH-adjusted pulp is then frozen and freeze-dried resulting in a dry pulp material which has good wetting and dispersion characteristics and a natural appearance in aqueous medium.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 55 words
A method for preparing a dry citrus pulp material comprising the step of raising the pH of the wet pulp material to a pH of at least 4.0, said pH being increased by the addition of a water-soluble, edible, inorganic basic material and thereafter freeze drying the pH-adjusted pulp and comminuting the freeze dried pulp.
Claim 2
Independent Claim 55 words
A method for preparing a dry citrus pulp material comprising the step of raising the pH of the wet pulp material to a pH of at least 4.0, said pH being increased by the addition of a water-soluble, edible, inorganic basic material and thereafter freeze drying the pH-adjusted pulp and comminuting the freeze dried pulp.
Claim 3
Dependent Claim 29 words
The method of claim 1 wherein a gum in the amount of 0.1 to 4% by weight of the wet pulp is added to the pulp prior to drying.
Claim 4
Dependent Claim 38 words
The method of claim 1 or 2 wherein a dextrin, having a D.E. of less than 20, in the amount of 0.5 to 20% by weight of the wet pulp is added to the pulp prior to drying.
Claim 5
Dependent Claim 15 words
The method of claim 1 wherein the basic material contains monovalent or divalent metal ions.
Claim 6
Dependent Claim 26 words
The method of claim 1 wherein the pH is increased by washing the pulp with water and thereafter adding a water soluble, edible, inorganic basic material.
Claim 7
Dependent Claim 17 words
The method according to claim 1 or 5 wherein the pulp is dried to below 10% moisture.
Claim 8
Dependent Claim 15 words
The freeze dried pulp produced in accordance with the method of claim 1 or 5.
Claim 9
Dependent Claim 31 words
A powdered beverage mix containing the pulp of claim 7 in an amount which will effect a pulp level in a reconstituted beverage of from 0.02 to 1.0 grams per quart.
