Gum
Gum, a sticky substance taken from plants. Gums are taken from the seeds of some plants, from the dried exudates (discharges) of other plants, and from the cell walls or tubers of a few plants. Some seaweeds can be processed to yield gums. Gums are either dissolved or softened by water, but are not soluble in alcohol. Gums impart viscosity (resistance to flow) to a liquid when dispersed in it.
Gums are an essential part of many glues and adhesives. Added to foods, gums thicken and stabilize them. Gums help to keep air in whipping cream and fats in salad dressings. Gum solutions slow down the growth of unwanted crystals in ice cream and candy. Gums are a part of many water-base paints, printing inks, and ointments. A gum called chicle is an essential ingredient in many types of chewing gum.
