Melting percent of frozen yogurts
The melting percent (weight basis) of the FYNRO, FYSC and PFY
was determined according to Isik et al. (2011). A 2.5-mm iron wire
mesh screenwas used. Samples were prepared by weighing a cubic
cut of frozen yogurt (of approximately 40 g) in a balance (Mettler
Toledo AG245, Mettler-Toledo Inc., Switzerland). Samples were
placed on the mesh screen, which was mounted on a beaker, and
the melted yogurt that passed through the screen was collected in
the beaker. The weight of the collected samples in the beaker was
recorded at 15, 30, and 45 min of melting at room temperature
(25 C). The melting percent was calculated as the ratio of these
values to the initial weight of the samples.
