چکیده مقاله:
The present study investigated the effects of frying and cooling of chicken nuggets under vacuum and atmospheric pressure on the qualitative properties of frying oil. For this purpose, first, two cooling treatments were applied to nuggets fried at ۱۷۰°C under atmospheric pressure. One treatment was subsequently cooled at atmospheric pressure (control) and the other at ۱۰ kPa. Other treatments included frying at temperatures of ۱۱۵ and ۱۷۰°C under the pressure of ۱۰ kPa before cooling at pressures of ۱۰ kPa and atmospheric levels. Results indicated that frying and cooling at ۱۷۰°C increased acid value, polar compounds, viscosity, redness, yellowness, and oil oxidation. Also, this treatment reduced the oil's unsaturated fatty acids. On the other hand, minimum values of acid content, viscosity, and oxidation rate were observed in the oil used to vacuum fry at ۱۱۵°C and subsequently cooled at ۱۰ kPa pressure. Moreover, these samples exhibited the highest quantities of oleic, linoleic, and linolenic acids due to the lower oxidation taking place in such unsaturated fatty acids under the vacuum rather than the atmospheric pressure. Based on the results obtained, frying and cooling at ۱۱۵°C under vacuum seems to have the least unfavorable effects on frying oil.
