Abstract
A composition for cleaning of dairy equipment comprising detergent, a mixture of sodium carbonate and sodium bicarbonate in a ratio of 1:5 to 3:1, and as from 1 to 100% w/w of the carbonates, an alkaline proteinase based upon a proteolytic activity of 1.5 Anson units per gram. Less proteinase may be employed but cleaning efficiency decreases substantially when the enzyme content is less than about 1%. A dairy cleaning solution containing the composition as 0.1-0.5% w/v in water exhibits pH 8.5-11. In hard water areas sodium tripoly phosphate may be included in the composition, being up to 0.125% w/v in the dairy cleaning solution. The carbonate content of the cleaning solution is from 0.05-0.25% w/v. The method involves passing a solution at about pH 8.5-11 of the composition through the dairy equipment at a solution temperature of ambient to 55.degree. C.
