<p>The tendency of sugar and sugar-containing foods to promote dental caries is diminished by adding to the sugar a bacteriolytic enzyme of animal or vegetable origin, notably the lysozyme of egg white. The lysozyme preparation used may be a solution of egg white or of a salt of the lysozyme, e.g. the hydrochloride, or may be in powder form, e.g. in lactose or dried egg white. Sodium chloride may be present to reinforce the action of the lysozyme. The preparation of lysozyme may be added to beet or cane sugar during the course of its manufacture, sufficient egg white being added for example to confer 10-90 micrograms of lysozyme per gram of sugar.</p> |
