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

A method to measure the level of acidity 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.

Analysis of NPN/Calculated urea in raw milk provides a useful indication of how effectively cows digest protein in the rumen providing vital information for feeding strategies and reproductive performances.

Analysis of Micronutrients in Milk by Flame Atomic Absorption Using FAST Flame Sample Automation for Increased Sample Throughput

Milk is an important source of nutrients, mainly for children. Because of its importance, milk is available in several different forms, most commonly as fresh, but it is also available in nonperishable forms (such as powdered and evaporated). Therefore, the requirement exists to analyze several forms of milk for nutritional elements. While ICP-OES is generally favored in a multi-element analytical environment, the cost savings, simplicity and speed of operation of a flame atomic absorption (AA) system provide an attractive alternative. Measuring multiple elements by flame AA requires each sample to be analyzed individually for each element, which impacts the speed advantage of flame AA – however, to address the speed issue, a fast, high-throughput sample automation system can be used. This work demonstrates the ability of the PinAAcle™ 900 AA spectrometer to reliably and effectively analyze common nutritional elements in a variety of milks over a wide range of concentrations. Coupling the PinAAcle 900 with the FAST Flame 2 sample automation accessory minimizes user error when performing dilutions and making calibration standards increases throughput and provides excellent long-term stability, increasing productivity for the laboratory.

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.
