Abstract
Background: The demand for vegetable oils is on the increase. Deep frying is the commonest method by which vegetable oils are consumed. The aim of this study was to extract oil from an underutilized oil seed and compare its physicochemical properties, frying, and oxidative stability with those of commercial refined palm oil.
Methods: Oil was extracted from Monodora myristica seeds using a soxhlet fat extractor and the percentage oil yield was determined. The physicochemical, oxidative, and frying stabilities of the extracted M. myristica Seed Oil (MMSO) were evaluated based on the standard procedure of the Association of Official Agricultural Chemists and official methods and recommended practices of the American Oil Chemists Society and compared with those of commercial refined palm oil- Kings Vegetable Oil (KVO). Data were statistically analyzed using SPSS version 20.
Results: The oil yield of M. myristica seed was 37.64%. The refractive index, specific gravity, moisture content (%), and peroxide value (mEq/kg) were respectively 1.470, 1.468, 0.923, and 0.917 for MMSO; and 0.220, 0.253, 1.05, and 3.50 for KVO. MMSO had better oxidative stability and showed 80% lesser peroxide formation than KVO. The frying stability of MMSO was better as it showed a lower increase in FFA (28.4%) and peroxide value (9.54 mEq/kg) than KVO (45.99% and 26.19 mEq/kg, respectively) after frying.
Conclusion: Deteriorative effect of oxidation and polymerization was lower in MMSO than in KVO indicating MMSO to be superior frying oil suitable for repeated frying.
期刊介绍:
Journal of Food Quality and Hazards Control (J. Food Qual. Hazards Control) is an international peer-reviewed quarterly journal that aims at publishing of high quality articles involved in food quality, food hygiene, food safety, and food control which scientists from all over the world may submit their manuscript. This academic journal aims to improve international exchange of new findings and recent developments in all aspects of agricultural and biological sciences. This free of charge journal is published in both online and print forms and welcomes the manuscripts that fulfill the general criteria of novelty and scientific importance. Among the most significant objectives of Journal of Food Quality and Hazards Control are to ensure that the articles reflect a wide range of topics regarding journal scopes; to do a fair, scientific, fast, as well as high quality peer-review process; to provide a wide and diverse geographical coverage of articles around the world; and to publish the articles having a trustable resource of scientific information for the audiences. The types of acceptable submissions include original article, review article, short communication, letter to the editor, case report, editorial, as well as book review. Journal of Food Quality and Hazards Control is an official journal of Research Center for Food Hygiene and Safety, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.
