| Abstract | A method of stir bar sorptive extraction (SBSE) and thermal desorption (TD) with gas chromatography–mass spectrometry (GC-MS) has been developed for qualitative and quantitative analysis of volatile and flavor compounds in grilled beef. To achieve optimum extraction and analysis performance for volatile and flavor compounds, desorption temperature and solid extraction conditions of the method were studied. Grilled beef and grilled beef dripping were analyzed by the developed method with short analysis program, and a total of 57 volatile (31 flavor) compounds, including 12 aldehydes, 13 hydrocarbons, 12 alcohols and ketones, 9 nitrogen- and sulfur-containing compounds, and 10 pyrazine compounds, were identified with little variation in triplicates. Four typical flavor compounds: hexanal, methional, 2-ethyl-pyrazine, and nonanal, were selected from main flavor group for quantitative analysis, and the method showed good linearity within the tested concentration range from 2 ng/g to 0.2 μg/g (n = 3, RSDs < 8 %) with good correlation coefficient (R $^{2}$ > 0.998) and good recovery at 38∼45 % by spiked standards of 100 ng/g (n = 3, RSDs ≤ 11 %) in ground grilled beef. The limits of detection (LOD) range was 0.17–0.26 ng/g (S/N = 3, n = 3), and the limits of quantification (LOQ) range was 0.56–0.88 ng/g (S/N = 9, n = 3) for flavor analysts. The simple, fast, and solvent-less method allows us to obtain reliable qualitative and quantitative data of volatile and flavor constituents which are necessary for the beef quality evaluation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
