Abstract
Compositions are described that use glucono delta lactone (GDL) in a portion of a composition containing two portions with differing water activities. GDL is included in a low water activity portion that is in contact with a high water activity portion, such that an interface formed between the two portions contains gluconic acid formed by contact of GDL with water from the high water activity portion. Methods of controlling pH in a composition containing two portions with differing water activities and methods of controlling microbial growth at an interface of two portions with differing water activities are also described.
