Studies on the Deterioration of Frying Oils in Continuous Water-Spraying and Heating System. IX. Frying Quality of Oils Used for Frying in Japan
Physical and chemical changes were compared with soybean oil, corn oil, cottonseed oil , rice oil, rapeseed oil, lard, palm oil and coconut oil in continuous water spraying and heating system (Table -1 , Fig,-1•`4). Thermal oxidative changes such as viscosity increasing ratio, carbonyl and iodine value , showed close relation with the initial iodine value of these oils. However, in coconut oil ...
متن کاملMonitoring of Used Frying Oils and Frying Times for Frying Chicken Nuggets Using Peroxide Value and Acid Value
This study was conducted to investigate the condition of frying oil used for frying chicken nuggets in a deep fryer. The acidification of the frying oils used, soybean oil (SB), canola oil (CA), palm oil (PA), and lard (LA), were determined as peroxide value, acid value, and fatty acid composition, after chicken nuggets were fried in them for 101 times. The acid value and peroxide value obtaine...
متن کاملEvaluation of Health Indicators and the Quality of Used Frying Oils in Fast Food Restaurants of Mashhad in 2018
Introduction: Recently, changes in people's lifestyles and new eating habits have diminished the importance of main dishes and have led to increasing the consumption of fast foods. Therefore, paying close attention to the health conditions and safety of the food provided in these centers can dramatically reduce the incidence of various diseases. The present study examines the environmental heal...
متن کاملEvaluating the Performance of Peroxide and Conjugated Diene Values in Monitoring Quality of Used Frying Oils
Frying oils showed an increase in Peroxide Value (PV) at the initial stages of the frying process followed by a decrease, and there was no correlation between PV and Total Polar Compounds (TPC) in the same set of frying oils. All the frying oils had PVs lower than 4.42 meq O2 kg -1 oil during the frying process and, consequently, none of them was above the limit of 10 meq O2 kg -1 oil for edibl...
متن کاملCarbonyl value in monitoring of the quality of used frying oils.
In this study, a set of frying oil samples of different compositional properties but passed qualitative and quantitative standards, which were of various vegetable oil sources (individually or as blends), were obtained from seven of big oil factories in Iran. Before starting the frying process, all the frying oils had carbonyl values (CV) higher than 2 micromol g(-1). The CV of most frying oils...
