Abstract
Thiosulfate in anhydrous form is added in minute amounts to beverages or food mixes, wherein tap water is added in quantities not greater than about one quart, to neutralize or destroy chlorines or chloramines in the water, such neutralization or destruction taking place almost instantaneously and, in any event, in a length of time not greater than about twenty seconds, depending upon the pH of the beverage or food. The thiosulfate may be added directly to the beverage or to the water or may be mixed with syrup or powder mix, and may be encapsulated with a food grade material which is readily dissolvable in water. Because of the rapid reaction of the thiosulfate with the chlorines and chloramines, the neutralization or destruction of same is essentially complete before a person commences to consume the food or beverage. The thiosulfate may be applied to articles which are inserted into the beverage or the food, or which receive same such as cups, stirrers, straws and the like.
