Quinces

Although most seeds contain starch as the principal food reserve, many contain other polysaccharides and some have industrial utility. The first seed gums used commercially were quince, psyUium, flax, and locust bean gum. However, only locust bean gum is stiU used, particularly in food appHcations quince and psyllium gums are only used in specialized appHcations. 

As predictable from the similarity of the properties of the two gums, quince seed gum is used in the appHcations described above for psyllium seed gum. Specific appHcations are in cosmetics and hair-setting lotions. It has also been used as an emulsifier and stabilizer in pharmaceutical preparations.

Closely related to plant gums are those mucilages discussed later which are the complex acid polysaccharides extractable from endosperms of seeds of such plants as flax, quince and lucerne (see below). The acid nature of these mucilages is due to the presence of D-galacturonic acid residues in the complex molecule. ...
