This test is a measure of the quantity of water (saline solution) which can be absorbed and retained by a granular starch. The starch is sealed in a teabag, immersed in water, drained, and the weight recorded (absorbent capacity). The teabag is then centrifuged and reweighed (retentive capacity).This procedure has been modified to account for starch lost through the teabag fabric.
