The present review provides an outline of the current knowledge of trans fatty acids (TFA) including their structure and formation, occurrence in foods, especially in meat and meat products, and some estimation and evaluation of daily intake. Special emphasis is put on conjugated linoleic acids (CLA), related to unique beneficial physiological properties, such as on cancer inhibition via the immune system.

Two plant species of the genus Anthriscus (A. sylvestris and A. cerefolium) and Laserpitium latifolium L. are described as a good source of new aroma constituents and phytosterols. These plants are the herbs widely distributed in Serbia and possess significant medicinal value. They are widely applied in traditional medicine, but they are not used as functional food or in food technology. Two well-known domestic aromatic plant species: Mentha piperita L. and Thymus vulgaris L.

Because of the importance of functional food factors for the nutrition of humans and animals, an increasing scientific interest has emerged in health related effects occurring as a consequence of their content in diet. Therefore, in this paper we tried to present the state of the art concerning nutritional aspects as well as health benefits of the most important and widespread ω-3 and ω-6 fatty acids.

Dried melon seeds (Citrullus colocynthis L.) of the family Cucurbitaceae were investigated for nutritional quality and the oil seed characteristics. These melon seeds, on a dry weight basis, consisted of 52.3% of test and 47.7% of kernel. The moisture content in melon seeds was 54.5% and the mineral constituents were also determined. The oil content of seeds was very high ranging from 22.1-53.5%, due to the presence of the hulls, 22% from the seeds and 53% of the kernel, and also the crude protein content was so high as the 21.8% of the seeds.

Packaging is very important for providing the food quality as its barrier to water vapor, aroma, and migration between the food and the environment. Different kinds of biopackaging of lipids are presented. It is especially pointed to the lipids used in edible films, mainly for their efficiency as water-vapor barriers. The structure, degree of saturation, chain length and distribution of lipids in film are discussed..

The seed oil from a local variety Rubus idaeus L. (family Rosaceae) was isolated and the physical and chemical characteristics were determined. The oil content of Rubus idaeus seeds ranged from 8-15%. Standard procedures were applied to determine specific gravity, refractive index, acid value, saponification value, iodine value and peroxide value.
