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.
A composition comprising:
A method of controlling pH in a composition, the method comprising, contacting a first portion of the composition with a second portion of the composition to form an interface, the first portion being high Aw and having a first pH, the second portion being low Aw and having a second pH, the second portion including GDL in an amount sufficiently distributed throughout the second portion to produce an interface pH that is below the second pH.
A method of controlling microbial growth at an interface of a composition, the method comprising contacting a first portion of the composition with a second portion of the composition to form the interface, the first portion being high Aw and comprising an antimicrobial compound, the second portion being low Aw and including GDL in an amount sufficiently distributed throughout the second portion to produce an interface pH that is sufficient to activate the antimicrobial compound.
