UV-C treatments were carried out in different setups according to
treatment media and research goal.
The effects of aw (solutions of
aw N 0.99, 0.90, and 0.80) and starch on the UV-C microbial lethality
were evaluated in the equipment described in Gayán et al. (2011)
which in this investigation has been renamed as UV-1 system.
In
short, this facility consisted of eight annular thin-film continuous
flow-through reactors connected in series and equipped with a feed
tank and a peristaltic pump (ISM 10785, Ismatec, Glattbrugg,
Switzerland).
