Uronide content

The polysaccharides present in the pectin-rich extract ChSS were fractionated, based on their charge density for further characterisation. The elution pattern of ChSS is shown in Figure 1, and it can be seen that the relative uronide content of the fractions increased with increasing salt concentration of the eluens. [Pg.514]

Figure 7 Illustrates the change In uronide content of the fractions obtained from the cell wall material as a function of the storage time at -20 C for the strawberry variety, Alko. It Is clear that the major change Is In the uronlc acid content of the water soluble fraction. This might be expected. If uronlc acid containing wall components are constituents of the material lost as drip. In table la we compare the cell wall fractions obtained by homogenizing thawed tissue, from which the drip has been lost, and frozen tissue, which has lost no material. There Is a loss of uronide In the...
