Several aspects define the quality characteristics of soymilk such as
colloidal stability, chemical changes and potential microbial growth, es-
pecially from the germination of the occasional presence of resistant
spores. All of them are crucial factors to take into account in the shelf-
life determination of products packaged under aseptic conditions. In ad-
dition to shelf-life determination, volatile profile could be considered as
an important factor related to consumer acceptance, for compromising
aroma and possibly taste quality due to the typical beany flavor gener-
ated by the compounds. Volatile compounds are derived from oxidation
process and include chemical families such as aldehydes, ketones,
furans, alcohols, esters and acids
