The mathematical prediction model for the oxidative stability
In the present study, the oxidative stability of vegetable oils, FAs, and FAMEs were well estimated by the parameter of T on derived from TGA carves by the non-isothermal pattern
Many countries like India, Sri Lanka, Bangladesh, Nepal etc. have great potential of producing edible and non-edible tree borne oils, which remain untapped and can be used as
- Can linseed oil be oxidated using PDSC and Rancimat methods?
- There are no studies on the kinetics of oxidation of linseed oil using PDSC and Rancimat methods, according to our knowledge. Therefore, the aim of this study was to compare the oxidative stability of linseed oil using these two methods. Material for the study consisted of five linseed oils (LO1, LO2, LO3, LO4, LO5).
- Does linseed oil have oxidative stability?
- Determination of the oxidative stability of linseed oil using the PDSC and Rancimat methods has been the subject of several studies (Rudnik et al. 2001; Omar et al. 2010; El-Waseif et al. 2013; Raczyk et al. 2015 ). However, only a limited number of kinetic parameters have been reported for the catalytic reactions of linseed oil.
- Does linseed oil oxidize?
- Linseed oil is rapidly oxidized, and the products of oxidation may have adverse effects on the human body. Several methods have been developed to evaluate oil oxidative stability. Due to time factors, which are very important for the industry, primarily accelerated tests are currently used to determined the oxidative stability of oil.
- What is the reaction rate coefficient of linseed oil oxidation?
- The reaction rate coefficient increased with rising temperature during measurement by both methods. The activation energy values of linseed oil oxidation using the PDSC and Rancimat methods ranged from 93.14 to 94.53 and 74.03 to 77.76 kJ mol −1, respectively.
- What is kinetic oxidation of linseed oil?
- The results of the kinetic oxidation of linseed oil enable to predict the process of oxidation under various conditions. The results might also be helpful in prediction of the oxidation of other oils. Acid value.
- Does a temperature increase increase linseed oil oxidation rate?
- The Q 10 for the analysed linseed oils using the PDSC method was an average of 2.12 and using the Rancimat method the value of this parameter was an average of 2.03; this indicated that a temperature increase of 10 °C caused more than double the rate of oxidation reaction.
