If edible coatings enriched with oleoresins are to be used as
natural biopreservatives in minimally processed vegetables, they
should not introduce deleterious effects on the sensory attributes
of the products. The overall visual quality (OVQ) was evaluated on
raw and cooked squash slices. Results obtained from fresh control,
dry control, and samples coated with edible films enriched with
rosemary and olive indicated that the edible coatings were imperceptible and the oleoresins, at the concentration used (1%), did not
produce residual aroma. The panelist found no differences in OVQ
among the different samples throughout the storage time. The use
of edible coatings enriched with rosemary and olive did not introduce
deleterious effects on the sensorial acceptability of minimally
processed squash.
