Abstract:
A method of obtaining selected pectin fractions having successively increasing setting times, the method comprising subjecting a starting material comprising high-esterified pectin to a first treatment cycle comprising a step of extracting the starting material with an aqueous extraction medium at an acidic pH under conditions where only a part of the pectin content is extracted, separating a pectin extract from the treated starting material and recovering the pectin from the pectin extract to obtain a first pectin fraction, followed by at least one further treatment cycle whereby the treated starting material extracted in a preceding treatment cycle is extracted with an aqueous extraction medium under conditions where at least a part of the pectin content is extracted from the treated starting material extracted in a preceding treatment cycle and recovering the pectin from at least a second pectin extract to obtain at least a second pectin fraction, the pH of the aqueous extraction medium in the at least one further treatment cycle being lower than in the immediately preceding treatment cycle, said at least second pectin fraction being separate from said first pectin fraction.
