Vacuum frying (VF) was tested as an alternative technique to produce high-quality fried food. This study
investigated the effects of oil temperature on the moisture loss, oil uptake, texture, color, and acrylamide
content of vacuum-fried versus atmospheric-fried breaded shrimps. The moisture loss and oil absorption
of breaded shrimps during VF were significantly affected (p < 0.05) by oil temperature. Oil absorption
was directly proportional to moisture loss during VF. The oil absorption of breaded shrimps during VF
increased with increasing temperature for the same frying time. After 10 min of frying, the oil contents of
breaded shrimps fried at 80 C, 100 C, and 120 C under vacuum conditions were 0.20 ± 0.013,
0.23 ± 0.012, and 0.25 ± 0.019 goil/gdry solid, respectively. These values were significantly lower than those
(0.32 ± 0.019 goil/gdry solid) obtained under atmospheric conditions (170 C). VF effectively decreased the
acrylamide content of breaded shrimps. Furthermore, breaded shrimps with desirable color and low
hardness can be produced using VF. These results indicate that VF is a feasible alternative technique to
produce high-quality breaded shrimps.
