Milk Adulteration with Melamine – Screening, Testing and Real-Time Detection

Screening, testing or real-time detection can be utilized to detect melamine-adulterated milk in a supply chain.The determination of where the sampling is taking place, who is carrying out the measurement and whether the testing is to meet regulation defines which technology to use.

The determination of residual lactose in lactose reduced milk by Lactoscope FTIR advanced

Method for the determination of residual lactose in milk by Lactoscope FTA .

Analysis of the NPN - Calculated urea in raw milk

Rapid routine determination of NPN/Calculated urea in raw milk with LactoScope FTIR milk analyzers. 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

This work demonstrates the ability to accurately measure nutritional elements in a variety of milk types by flame atomic absorption using FAST Flame sample automation for high sample throughput.

Screening for Melamine in milk by Lactoscope FTIR

A practical screening method for the presence of melamine down to a level of 500 ppm or 0.05%m/m using Lactoscope FTIR is presented here. The discrimination limit can be further reduced to 100 ppm (0.01%m/m) using the melamine specific detection model.

Analysis of Micronutrients in Milk Using the Avio 200 ICP-OES

With its great importance, milk is available in several different forms: fresh, boxed (ultraheat treated), powdered, and evaporated. The most commonly consumed form varies globally, being dependent on factors such as geography, culture, and climate. For milk producers, internal quality control and the possibility of external monitoring provide strong incentives for the ability to quickly, accurately, and easily monitor nutrients in their products.

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

This work demonstrates the ability to accurately measure nutritional elements in a variety of milk types by flame atomic absorption using FAST Flame sample automation for high sample throughput.

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.

Evaporated Milk - DA 7250

Evaporated milk is an important ingredient for many products and an important form for long term storage of milk. The total solids and fat content are keys to proper performance as an ingredient and long term storage. Correct uantities impart both functional and flavor characteristics. In addition, accurate control of total solids and fat can optimize profitability of the processor. The Diode Array 7250 can accurately analyze evaporated milk for total soids and fat content. The speed of analysis allows users to easily and accurately analyze many samples a day in nearly real time.

Youghurt - DA 7250

For yoghurtmanufacturers, fat and dry matter contents are important quality parameters that define properties of the end product. With a large number of samples, high sample throughput and accurate determination of these parameters is of great benefit. The DA 7250 can analyze yogurt in less than 10 seconds with high accuracy. Even including inhomogeneous samples with fruit pieces and without the need to clean sample cups, vials, tubes or similar in between measurements.
