Provided is a pectin having (i) a degree of esterification (DE) of 60 to 95%, (ii) a calcium sensitivity (.DELTA.CS) of less than 25 cP, and (iii) a calcium sensitive pectin weight ratio (CSPR) of calcium sensitive pectin (CSP) to the sum of CSP and non-calcium sensitive pectin (NCSP) of 0.7 or more. Such pectin is useful as a stabilizing component of an aqueous acidic beverage, such as a drinking yogurt, which contains a suspension of protein particles formed from, e.g., casein. The pectin can be prepared by treating a substantially non-calcium sensitive pectin having a CSPR of 0.1 or less and a .DELTA.CS of 0-3 with a pectin deesterifying enzyme.

Con tal que sea una pectina que tiene (i) a grado del esterification (DE) de 60 a el 95%, (ii) una sensibilidad del calcio (DELTA.CS) de menos de 25 P, y (iii) un cociente sensible del peso de la pectina del calcio (CSPR) de la pectina sensible del calcio (CSP) a la suma de CSP y de la pectina sensible del no-calcio (NCSP) de 0.7 o más. Tal pectina es útil como componente que se estabiliza de una bebida ácida acuosa, tal como un yogur que bebe, de el cual contiene una suspensión de las partículas de la proteína formadas, e.g., caseína. La pectina puede ser preparada tratando substancialmente una pectina sensible del no-calcio que tiene un CSPR de 0.1 o menos y los DELTA.CS de 0-3 con una enzima deesterifying de la pectina.
