This 'pectin' is therefore a form of soluble lignocellulose.
Pectose is a modification of pectin; it is insoluble in water.
The first pectin test should be saved for comparison with the others.
If available, a mixture of kaolin and pectin should be given for diarrhea.
If the pectin collects in two or three masses, use 2/3 to ¾ as much sugar as juice.
The pectin may be supplied by the addition of the juice of crab-apples or under-ripe grapes.
Measure juice and sugar in proportions indicated by the test for pectin or as directed under "Jelly Making without Test."
Pectin is also a carbohydrate that is found in large quantities in some fruits, while in other fruits it is lacking.
They cannot be used for jelly, because they do not contain sufficient acid nor pectin.
The chief requirement of fruits that are to be used for jelly making is that they contain acid and pectin.
