You can visit FDA website to find out the specification for edible fats and oils especially for FFA content, PUFA content etc. or simply you can check some oils produced in Europe and North America for a quick idea.

Hello Mr. Ahmed

Thanks for your attention

I visit the FDA website and understood that trans fatty acids cannot be used in food industry but don't find the alternatives. Do you know what are those?

Dear Ahmad,

Trans fatty acids (TFAs), occur both naturally in foods and can be formed or added to foods during manufacture. Naturally occurring TFAs are found in some animal products including butter, cheese and meat. Manufactured TFAs (also known as artificial TFAs) are formed when liquid vegetable oils are partially hydrogenated or ‘hardened’ during processing to create spreads such as margarine, cooking fats for deep-frying and shortening for baking. Some TFAs are also formed during high temperature cooking.

There is strong evidence that TFAs increase the amount of ‘bad’ low-density lipoprotein (LDL) cholesterol in our blood, a major risk factor for coronary heart disease. Also, TFAs may decrease the levels of ‘good’ high-density lipoprotein (HDL) cholesterol in blood. The World Health Organization (WHO) recommends that no more than 1 per cent of our daily energy intake (kilojoules) should come from TFAs. 

Now, if you realize, there are many oil sources free of significant trans fatty acids (many vegetable and plant oils) you can use for your purpose. More over, there is also a recommended limit of TFAs amount uptake.
