Sun, Xuelian;Wang, Yajie;Li, Huankang;Zhou, Jing;Han, Jiajia;Wei, Changqing research published 《 Changes in the volatile profile, fatty acid composition and oxidative stability of flaxseed oil during heating at different temperatures》, the research content is summarized as follows. The deterioration of flaxseed oil (FSO) during heating greatly influences the quality of fried foods. FSOs heated at different temperatures (120 °C, 150 °C, 180 °C, and 210 °C) were investigated for volatile organic compound (VOC) and fatty acid compositions and physicochem. indexes. In total, 84 VOCs were identified, including 20 aldehydes (37.43%-66.17%), 20 alcs. (31.19%-42.90%), 9 esters (0.28%-1.27%), 8 ketones (0.4%-1.58%), 19 alkanes (1.15%-19.96%), and 8 heterocyclics (0.68%-6.16%). Furthermore, 1-nonanal, 2,4-decadienal, hexanal, and trans,trans-2,4-heptadienal were identified as the characteristic aroma compounds to estimate the oxidation degree of heated FSO through the calculation of odor activity values. The polyunsaturated fatty acid content in FSO significantly (p < 0.05) decreased by 5.75 μg/g after heating at 210 °C. The physicochem. indexes of FSO increased during heating with acid, peroxide, p-anisidine and thiobarbituric acid values ranging from 0.26 to 0.55 mg NaOH/g, 0.041-0.066 g/100 g, 0.12-0.88, and 0.025-0.088, resp. Results of Pearson correlation anal. indicate that 2,4-decadienal and hexanal may be oxidation deterioration markers in FSO. This study provides a theor. basis for evaluation of the suitability of FSO for household food preparation
22047-25-2, 2-Acetylpyrazine has been identified as one of the volatile flavor constituents in popcorn, wheat and rye bread crust.
2-Acetylpyrazine, also known as 1-pyrazinylethanone or fema 3126, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R’, where R = aryl group and R’=alkyl group. 2-Acetylpyrazine exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 2-acetylpyrazine is primarily located in the cytoplasm. 2-Acetylpyrazine has a bitter, bread crust, and chip taste.
2-acetylpyrazine is a pyrazine that is substituted by an acetyl group at position 2. It has been identified as one of the volatile flavor constituents in popcorn, bread crust, vinegar, and potato snacks. It has a role as a flavouring agent. It is an aromatic ketone and a member of pyrazines.
2-Acetylpyrazine is a nitrogen containing compound that has been used in biological studies. 2-Acetylpyrazine has been shown to have inhibitory properties against the growth of prostate cancer cells and other cell lines. It also inhibits the production of fatty acids and epidermal growth factor, which are important for cellular proliferation. The inhibition is due to the photochemical properties of 2-acetylpyrazine, which cause the formation of reactive species that react with biological molecules. The reactive species may be generated by either a reaction mechanism or a reaction pathway that involve coordination geometry. 2-acetylpyrazine has also been used as a fluorescence probe for fatty acid detection in lipid bilayers and liposomes., Application of C6H6N2O
