摘要： The present disclosure relates to compounds of the formula (I) which are precursor compounds of esters, whereby upon hydrolysis of the precursor compound, an ester compound is released. This ester precursor approach can be useful for applications where controlled release of, for example, ethyl formate, is beneficial.

摘要： It is provided a composition for controlled-release of volatile compounds comprising at least one poly(ethylene glycol) (PEG) polymer and one or more volatile compounds, the composition used for preserving food when incorporated in a food packaging. The volatile compounds are antimicrobial compounds such as allyl isothiocyanate (AITC), diacetyl, cinnamaldehyde, thymol, carvacrol and a combination thereof. The composition can comprise a blend of two or more PEG polymers of different molecular weights and/or a mixture of poly(lactic acid) (PLA) and poly(ethylene oxide) (PEO).

摘要： The invention provides methods for the encapsulation of volatile organic compounds by formation of stable emulsions of the volatile organic compound that are mixed with encapsulating polymer solutions and then formed into ultrafine fibers. The ultrafine fibers containing the encapsulated volatile organic compounds can be formed into a variety of formats for use to preserve perishable products.
