Issue Date: | Dec-2015 | Publisher: | Wiley | Journal: | Journal of Food Processing and Preservation | Abstract: | © 2015 Wiley Periodicals, Inc. Effects of endpoint temperatures of 51, 61, 71, 81 and 91C on mineral contents (mg/100g WW, wet weight) of pork loin (longissimus thoracis et lumborum, n = 12) were investigated. Pork was cooked in water bath set to 100C. In both raw and cooked samples, phosphorus was determined by the standard spectrophotometric method while metals (potassium, sodium, magnesium, calcium, zinc, iron, copper and manganese) were determined by the flame atomic absorption spectrometry after mineralization by dry ashing. All cooking treatments led to significantly increased mineral contents, except for potassium and sodium, compared to raw meat. As endpoint temperature was increased, mineral contents increased, reaching numerically or significantly highest contents at: 61C for sodium and magnesium; 71C for phosphorus, potassium, calcium, zinc, copper and manganese; and 81C for iron, after which mineral contents decreased. Practical Applications: During cooking, the meat undergoes changes in its physical properties and chemical composition. Cooking temperature and especially endpoint internal temperature affect mineral contents of cooked pork. Thus, it is important to know the extent of mineral losses occurring during different boiling treatments. Data in the most food composition tables are based on mineral contents of raw meat. The results provide update and improve regularly nutrient compositional data of meat. | URI: | https://open.uns.ac.rs/handle/123456789/5279 | ISSN: | 01458892 | DOI: | 10.1111/jfpp.12422 |
