Development of a new and sensitive method for the detection of pork adulteration in gelatin and other highly processed food products.

Porcine adulteration has become a major concern amongst communities including Muslims and Jews. Reliable detection of the presence of porcine DNA in gelatin and highly processed food samples is essential for Halal and kosher food control. In this study, a forensic approach involving DNA isolation and real-time polymerase chain reaction (PCR) was performed to detect the presence of porcine DNA in commercial gelatin and processed foods containing porcine by-products.

A rapid ATR-FTIR spectroscopic method for classification of gelatin gummy candies in relation to the gelatin source.

Gelatin is widely used in gummy candies because of its unique functional properties. Generally, porcine and bovine gelatins are used in the food industry. FTIR-ATR combined with chemometrics analysis such as hierarchical cluster analysis (HCA) (OPUS Version 7.

A survey of free glutamic acid in foods using a robust LC-MS/MS method.

An effective and simultaneous liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was used with the aim of quantifying monosodium glutamate (MSG) in foodstuffs, such as chips, taste cubes, sauces and soups. The results were linear (R = 1), with very low LOD and LOQ values, 1.0 µg/kg, 5.

Detection of l-Cysteine in wheat flour by Raman microspectroscopy combined chemometrics of HCA and PCA.

l-Cysteine is deliberately added to various flour types since l-Cysteine has enabled favorable baking conditions such as low viscosity, increased elasticity and rise during baking. In Turkey, usage of l-Cysteine as a food additive isn't allowed in wheat flour according to the Turkish Food Codex Regulation on food additives. There is an urgent need for effective methods to detect l-Cysteine in wheat flour.

Formaldehyde migration in aqueous extracts from paper and cardboard food packaging materials in Turkey.

Migration of formaldehyde to aqueous extracts from paper and cardboard food packaging materials was determined by an ultraviolet visible-spectrophotometric method at 410 nm. Intraday and interday precision of the method, expressed as coefficient of variation, varied between 1.5 to 4.

Biosorption of Au (III) and Cu (II) from aqueous solution by a non-living Cetraria islandica (L.) Ach.

Biosorption of Au(III) and Cu(II) from dilute aqueous solutions was investigated by biomass of the non-living Cetraria islandica (L.) Ach. The removal and recovery of gold and copper were studied by applying batch technique.
