Chromatographic profile of carbohydrates in commercial soluble coffees
Pure soluble coffee, irrespective of extraction conditions, contains maximum levels of ca. 0,3 percent total xylose and sucrose, no maltose, and about 2 percent total glucose. Some commercial soluble coffees have been found to contain one or more of these sugars at higher levels. Elevated levels of total xylose are explained by coextraction with coffee husks/parchment. In this case, the level of free fructose and glucose distinguishes whether unroasted or roasted husks/parchments have been added. Elevated levels of maltose and total glucose indicate the addition of maltodextrins. Elevated levels of sucrose and total glucose show the addition of (caramelized) sugar
