Quality and vitamin A status assessment of different commercial edible oil

Abstract

The present study was done to evaluate the quality and the vitamin A fortification status of 5 types of commercial edible oils sold in Dhaka city markets. The percentages of free fatty acid (FFA), peroxide value (POV), iodine value (IV) and fatty acid composition were estimated to evaluate the quality and vitamin A content were determined to evaluate the vitamin A fortification status of 25 commercial edible oils- soybean oil, sunflower oil, rice bran oil, mustard oil and palm olein (5 brands of each) . The results revealed that FFA, POV and IV of the commercial oils analyzed were within the BSTI standard limits. The highest saturated fatty acids (SFA) values ranging from 39.85 ± 0.005 to 46.97 ± 0.002 % was found in palm olein samples and the lowest SFA values ranging from 4.56 ± 0.031 to 6.97 ± 0.096 % was found in mustard oils. On the other hand, mustard oils contained highest monounsaturated fatty acids (MUFA) ranging from 69.30 ± 0.189 to 75.87 ± 0.069 % compared to other oils analyzed. Highest polyunsaturated fatty acids (PUFA) were recorded in sunflower oils 64.78 ± 0.035% followed by soybean oils 63.25 ± 0.245%. In addition, except sunflower and mustard oils, vitamin A was found in all the soybean and rice bran oils analyzed. On the contrary, vitamin A was found only in 60% of the palm olein samples analyzed and the content was much lower than the standard value (15-30 ppm).

Fortified edible oils in Bangladesh: A study on vitamin A fortification and physicochemical properties

“…[ 33 ]. However, these values were consistent with the results of Lisa et al [ 25 ]. The free fatty acid concentration of sunflower samples was also determined and found to be within the acceptable range (<0.30 %) where SF1 and SF2 had 0.15 % and 0.17 % respectively.…”

“…Nevertheless, all examined brands of soybean oil were discovered to be fortified. The results of this study align with the findings of Lisa et al [ 25 ] and Ahmed et al [ 26 ], indicating that fortified edible oils contained vitamin A levels below the recommended amount.…”

Sunflower oil quality management based on statistical analysis of its indicators

“…It is known that sunflower oil contains oleic, linoleic, linolenic fatty acids, which are about 95%. Sunflower is the most widespread oilseed crop, containing more than 50% of oil in its seeds which are mainly used as a food [2,3].…”

“…One of the most Sunflower oil is very tasty and exceeds other vegetable oils in terms of nutritional value and digestibility. Sunflower oil contains nutrients valuable for the body, as well as vitamins of groups A, D, E and F [7].…”

Исследование Функционального Состава Подсолнечного Масла, Полученного Методом Холодного Прессования

“…Обогащение масла витаминами необходимо для питания, т. к. они способствуют улучшению здоровья, а их дефицит очень опасен. Они относятся к незаменимым веще-ствам, т. к. участвуют в обмене веществ, росте организма, защищают от внешних воздействий среды и должны приниматься регулярно [6].…”
