Abstract
Abstract Per capita meat consumption in Chile is 89.1 kg per year in 2014, of which approximately 25 kg are beef. Some 50% of the beef consumed is imported as vacuum packaged meat from two species, Bos taurus, produced mainly in Chile, Argentina and Paraguay, and Bos indicus, which comes mainly from Brazil and Paraguay. The latter two countries account for the highest levels of beef imports in Chile. The objective of this investigation was to study and compare the fatty acid profiles of beef from Bos Taurus from Chile and Bos indicus from Paraguay and Brazil. Samples of vacuum packaged Longissimus dorsi muscle tissue were collected from private companies, two Chilean, three Paraguayan and two Brazilian. The fatty acid profiles were determined by GLC according to standardized regulations. There were differences in the fat profiles of the analyzed meats, mainly in the content of saturated and monounsaturated fatty acids. Brazilian and Paraguayan beef had similar fat compositions, with higher saturated fat content and lower monounsaturated fat content than the Chilean beef. The saturated and monounsaturated fat contents in the Chilean beef were similar. All the analyzed beef samples had a low content of trans and polyunsaturated fats.
Highlights
Meat consumption in Chile is at an historic high
Imported beef in refrigeration comes from two species Bos taurus taurus, which is produced in Argentina and Uruguay, and Bos taurus indicus, which comes mainly from Brazil and Paraguay, the latter two countries being the major sources of imported beef to Chile (Chile, 2014)
The objective of the present work was to determine and compare the fatty acid profiles of beef of the species Bos Taurus from Chile and Bos indicus from Paraguay and Brazil, which are sold in Chile
Summary
Meat consumption in Chile is at an historic high. According to the ODEPA (Chile, 2014), per capita meat consumption was 89.1 Kg, 3.5% over what was recorded for 2012 (87.5 kilos). Of this volume, 37.5 Kg was poultry, 26.6 Kg pork and 24.4 Kg beef. Beef production in 2013 continued the rising trend of previous years, with a cumulative increase since 2010 of 6.4%. Despite the increase production is not meeting demand and meat imports fill the gap. Of the 24.4 kilos of beef sold per capita per year, 50% is imported. Imported beef in refrigeration (vacuum packaged) comes from two species Bos taurus taurus, which is produced in Argentina and Uruguay, and Bos taurus indicus, which comes mainly from Brazil and Paraguay, the latter two countries being the major sources of imported beef to Chile (Chile, 2014)
