Bound salads and other food products can enjoy decreased separation with the addition of a source of glucomannan, especially at from 0.1 wt % glucomannan and higher. Glucomannan absorbs substantial amounts of moisture released by the inclusions such as tuna fish, potatoes, vegetables etc, and as such, prevents &ldquowatering out&rdquo of the salad. Moreover, glucomannan is resistant to certain enzymes released by the inclusions such as carrots, cabbage, vegetables, fruits etc. Particularly important in this respect are amylases. By virtue of its resistance to amylase, glucomannan can thicken dressings in light products such as light mayonnaise, which often include starches subject to degradation by amylase, with little or minimal &ldquowatering out&rdquo in extended use.
