Several aspects define the quality characteristics of soymilk such as
colloidal stability, chemical changes and potential microbial growth, especially 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 addition 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 generated by the compounds. Volatile compounds are derived from oxidation
process and include chemical families such as aldehydes, ketones,
furans, alcohols, esters and acids
