Nuclear magnetic resonance (NMR) spectroscopy is a non-destructive and non-invasive analytical chemical technique that is also increasingly used in food chemistry. The method allows specification of a broad group of components in foodstuffs characterised by a simple or complex form of matrix, as in meat and meat products. While NMR studies on fresh meat are … [Read more…]
Pork meat is an important source of protein for humans. With the exception of vitamin C, it contains almost all the vitamins (in particular vitamin B6, vitamin B12, riboflavin and niacin) or their pro-vitamins, and is also a valuable source of minerals (in particular phosphorus, potassium and zinc) (Murphy et al. 2011).

Beef consumption can to some extent be considered an indicator of the purchasing power of the population. Since 1995, beef consumption in Europe has slumped by approximately 11%. Another significant fall of around 5% was caused … [Read more…]
This thesis focuses on the determination of protein content in selected meat products using the Kjeldahl method, which is suitable for all food categories and is direct, reliable, internationally accepted („arbitrage“) as well as suitable for insoluble proteins. Using a method for the determination of hydroxyproline (according to the standard ISO 3496) we obtained the … [Read more…]
