Performance of phytochemical antioxidant systems in refined-bleached-deodorized palm olein during frying.
Antioxidants are important inhibitory compounds against the oxidative deterioration of food. This study investigated the effects of various phytochemical antioxidant systems [oleoresin rosemary (OR), oleoresin sage (OS) and citric acid (CA)] on the physico-chemical characteristics of refined, bleached and deodorized (RBD) palm olein during the frying of potato chips. The effects of various mixt...
متن کاملThe Digestion , Absorption and Utilization of Refined Palm Oil , Palm Olein and Palm
A nutritional evaluation of refined, bleached and deodorised (RBD) palm oil and its fractionation products, RBD palm olein and RBD palm stearin in terms of their digestibility, rate of absorption and food efficiency in rats, shows that RBD palm olein is a better oil by these criteria than RBD palm stearin and the unfractionated RBD palm oil. Nevertheless, the nutritional indices reported for RB...
متن کاملPalm 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 کاملFourier Transform Infrared Spectroscopy applied for rapid analysis of lard in palm oil
The presence of lard in vegetable oils like palm oil is serious matter for certain communities like Muslim and Hindis. Fourier transform infrared (FTIR) spectroscopy has been used for determination of lard in palm oil. Lard, palm oil and their binary mixtures in the neat form was scanned at mid infrared region (4,000 – 650 cm-1) using attenuated total reflectance accessory as convenient samplin...
متن کاملEnzymatic Synthesis of Fatty
Fatty hydrazides (FH) have been successfully synthesized from palm oils by a one-step lipase catalyzed reaction. The synthesis was carried out by treating the oils with hydrazine hydrate at neutral pH using an immobilized lipase, Lipozyme as the catalyst. The percentages of conversion of RBD (refined, bleached and deodorized) palm oil (PO), RBD palm olein (POn), RBD palm stearin (PS) and RBD pa...
