Palm oil and palm olein frying applications.
Several million tones of palm oil and palm olein are used annually in the world for frying. This paper will discuss their frying performances in three major applications - industrial production of potato chips/crisps, industrial production of pre-fried frozen French fries and in fast food outlets. In the first study, about four tones of potato chips were continuously fried 8 hours a day and fiv...
متن کاملChanges of Major Antioxidant Compounds and Radical Scavenging Activity of Palm Oil and Rice Bran Oil during Deep-Frying.
Changes in antioxidant properties and degradation of bioactives in palm oil (PO) and rice bran oil (RBO) during deep-frying were investigated. The alpha (α)-tocopherol, gamma (γ)-tocotrienol and γ-oryzanol contents of the deep-fried oils were monitored using high performance liquid chromatography, and antioxidant activity was determined using 2-diphenyl-1-picryl hydrazyl (DPPH) radical scavengi...
متن کاملChromatographic analyses of tocopherols and tocotrienols in palm oil.
Analyses of tocols (tocopherols and tocotrienols) in palm oil have been extensively reported in the past. However, due to the scarcity of individual tocotrienol standards, calibrations have mostly been carried out using only α-tocopherol as standard. Moreover, even if the individual tocotrienols are being used, their reliability is often questioned, because tocotrienols are highly susceptible t...
متن کاملPerformance of Different Natural Antioxidant Compounds in Frying Oil.
In this study, the natural green tea extract, purified lycopene, purified resveratrol and purified γ-oryzanol were added into peanut oil and their antioxidant performances were evaluated during frying. Moreover, the sensory properties of fried dough were evaluated to determine the consumption feasibility. All natural antioxidants led to significant increase in the stability of the oil samples. ...
متن کاملAlternative Methods of Frying and Antioxidant Stability in Soybean Oil
A study on shallow and parfrying in soybean oil as alternatives to deep frying and evaluation of stability of a formulated antioxidant administered to the oil was conducted. Potato wedges were deep, shallow and parfried in soybean oil for optimized time and temperature. A citric acid based antioxidant using BHT was formulated and administered to the oils before frying. The performance of antiox...
