Summary

Trans fats, also named trans fatty acids (TFAs) are a particular type of unsaturated fatty acid. The partial hydrogenation used in food industry lowers the number of double bonds and increases the hydrogen amount thus creating trans fats.

The mandatory requirement in many countries to declare the amount of trans fat present in food products which led to the need for sensitive and accurate methodologies for a rapid quantification of trans fats.

The originality and novelty of the project is based on a complex investigation for the detection of TFAs in vegetable oils and food products by the combination of complementary analytical methods such as GC-FID, GC-MS, FT-IR, Raman and also with chemometric methods for the processing of analytical data.

The limits of the current approaches in the field are related mainly to the following aspects:

1). Until now there are no studies regarding the measurement of content and distribution of trans fatty acids in food products present on the Romanian market although there is COMMISSION REGULATION (EU) 2019/649 that is to apply from 1 April 2021 for all the countries of the European Union and which limits TFAs in foods (maximum 2 grams per 100 grams of fat);

2). Until now in Romania there are no validated analytical methods regarding the assessment and distribution of fatty acids in food;

3). In Romania the food products are not labelling correctly, the content of trans fatty acids not being specified.
