The growing interest in the substitution of ‘traditional food preservatives’, both antimicrobials and antioxidants, by natural ones has fostered research on vegetable sources and the screening of plant materials. It has been known since ancient times that spices and their essential oils have varying degrees of antimicrobial activity.

The liver is an organ of paramount importance and plays an essential role in the metabolism of foreign compounds entering the body. Human beings are being exposed to these compounds through environment exposure, consumption of contaminated food or during exposure to chemical substances in the occupational environment.

Coriander (Coriandrum sativum L.) is grown as a spice crop all over the world. The seeds have been used to treat indigestion, diabetes, rheumatism and pain in the joints.

Coriander (Coriandrum sativum L.) is aromatic plant which is widely distributed and cultivated in Mediterranean countries. The coriander seeds contain an essential oil (up to 1%), where monoterpenoid linalool is the main compound (>50%), and limonene, camphor and geraniol are present in significant quantity.

There is great interest in plant polyphenolic com-pounds because of their potential roles as cancer chem-opreventive agents and chronic disease protectors. Their beneficial effect is considered to be mainly due to their antioxidant and chelating activities.

Research has shown that aqueous and etheric coriander extracts, composed of phenolics and carotenoids, exhibit a considerable antioxidant action.

Fish is a valuable source of protein and contains high amounts of ω-3 polyunsaturated fatty acids (PUFAs) which play an important role in a healthy diet (Avadi & Freon, 2015). Generally, due to the high amounts of free amino acids, volatile basic nitrogen and PUFAs in fish, they are more perishable compared to red meat and poultry meat (Hoel, Jakobsen, & Vadstein, 2017).

Oxidative stress is the imbalance between the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS) and their clearance by the antioxidants.

Medicinal plants have therapeutic potential due to the presence of natural antioxidants functioning as reducing agents, free radical scavengers and quenchers of singlet oxygen. Majority of their antioxidant activity is due to bioactive compounds viz. flavones, isoflavones, flavonoids, anthocyanins, coumarins, lignans, catechins and isocatechins. Currently there has been an increasing interest to identify the antioxidants that are pharmacologically potent with low or no side effects for use in preventive medicine.

Lipid peroxidation is a complex process which is initiated by abstraction of hydrogen atoms from unsaturated fatty acids of phospholipid and lipoprotein complexes yielding conjugated dienes. The conjugated dienes then react with molecular oxygen to produce peroxy radicals which propagate the chain reaction by abstracting hydrogen from other unsaturated Iipids.

The positive relationship observed between the RSA of crude oils and their color intensity suggests the Maillard reaction products may have contributed to the RSA of seed oils and their polar fractions. The results demonstrate the importance of minor components in crude seed oils on their oxidative stability, which will reflect on their food value and shelf life. As part of the effort to assess the potential of these seed oils, the information is also of importance in processing and utilizing the crude oils and their byproducts.
