Abstract
Pecto-cellulosic compositions are prepared by treating comminuted citrus peel or other pectin-containing material in an acidified aqueous solution to solubilize pectin. The pectin is then recovered in the cellulosic matrix of the citrus peel by adjusting the pH of the solution and dried. The resulting pecto-cellulosic product is incorporated in food and other products.
Claims11
A method for preparing pecto-cellulosic compositions from a pectin-containing plant raw material without a step of alcohol precipitation, said method comprising:
- combining comminuted raw material with an acidified aqueous solution comprising a food acid and incubating the comminuted raw material in the acidified aqueous solution at less than about 50.degree. C. for about 8 to about 24 hours, thereby producing a mixture comprising a solid phase containing cellulosic components and a liquid phase containing solubilized pectin;
- pureeing the mixture, while the mixture is in the acidified aqueous solution, thereby producing particles less than about 200 .mu.m;
- partially neutralizing the pH of the mixture;
- and
- drying the mixture, thereby producing pecto-cellulosic solids.
