Abstract
Objectives:Determination of gross chemical composition of studied sauces Determination of chemical indices of extracted oil from studied sauces before and after marinating .Determination of fatty acid composition of extracted oil from studied sauces.•Studying the effect of marinating, cooking and storage for 2 - 4 months of studied sauces on fatty acid composition.Determination of phenolic compounds in studied sauces. Studying the effect of cooking on phenolic compounds in studied sauces. Studying the effect of marinating, cooking and storage on antioxidant activity of sauces. Methods and results:Have used classical methods to estimate some basic elements of the raw materials and finished products of this study were also used some modern methods of analysis such as the gas chromatography in the estimation of of fatty acids content, as well as measuring antioxidant activity content and active phenolic compounds and their changes by HPLC, one of the modern sophisticated estimates.For the results of which have been for them to be identical with the results of many local researchers and foreigners, and showed that herbs and spices are excellent sources of antioxidants and phenolic compounds, and these results are shown in (13)Tables and (9 ) figures.Conclusion:from the above mentioned results it could be seen that Preference spiced tomato sauce about green seasoning sauce back to the following:All chemical indices of STS (acid value, free fatty acids, peroxide and thiobarbituric acid values) and fatty acids composition for oil were the best in all treatments, as well as at cold storage, which means it’s more stable. Results show that the marinating process as well as marinating and cooking led to increase saturated fatty acid contents at the expense of unsaturated fatty acids. As well as marinating and cooking process affected on phenolic compound contents by increase or decrease and creating or decomposition some phenolic compounds. Also marinating and cooking process led to reduction antioxidant activity especially in GSS.
