It was postulated that the proprietary method considered in
this study (Duffield & Matula, 2010) could be used in conjunction
with normal processing methods to increase available lycopene
in processed tomatoes by increasing its release from tomato tissues
and increasing its cis-isomeric content of lycopene. (Preliminary
results of treated tomato samples indicated a change in
isomeric content of lycopene.) For these reasons, its complete
extraction from food sources both for use as an additive and measurement
of total lycopene content is of interest.
