Abstract

The invention is a method of venting the degradation products of an ascorbic acid containing composition. This prevents a build-up of carbon dioxide and may prolong the life of the packaging. The packaging includes an impermeable container and a semi-permeable top, which allows carbon dioxide to vent over time. When the composition includes water, the surface area of semi-permeable material contacting the composition is reduced to lessen water vapor loss.
