Measure the level of accidity in a milk sample using FTIR technology

A method to measure the level of accidity in a milk sample using FTIR technology

The Analysis of Lactose in Milk and Cheese Products by HPLC

Lactose, also referred to as milk sugar, is the primary carbohydrate present in dairy products. Globally, the analysis of lactose is especially important due to the many individuals suffering from lactose intolerance. The work presented herein provides a method for the routine sample preparation and quantitative determination of lactose in mozzarella and ricotta cheeses and milk. As the monosaccharaides glucose and galactose can be hydrolytically or enzymatically produced from lactose, these two sugars were also chromatographically separated, though not quantitated. The method uses an Altus™ HPLC system with refractive index (RI) detector, which is especially effective for analyzing analytes with little or no UV absorption, such as many dietary sugars.

Instrument design characteristics eliminate deposition on the ion optics, leading to long-term stability in high-matrix samples, while permitting trace levels to be accurately measured.

The Elemental Analysis of Meat and Seafood with the NexION 300/350 ICP-MS

The elemental content of food products is very important, both in relation to nutritional and toxic elements. Nutritional elements can either be native to the food substance or can be added to enhance the health benefits. Toxic elements can enter food either through the environment or processing during production. Hopefully, toxic elements will be present at extremely low levels, while nutritional elements will be present at optimal levels. The elemental capabilities and dynamic range of inductively coupled plasma mass spectrometry (ICP-MS) make it ideally suited for the analysis of food materials. This work has demonstrates the ability of PerkinElmer’s NexION 300/350X ICP-MS to effectively measure macro-level nutritional elements in the same analysis run as lower-level elements, without having to dilute the samples.
