Since 25 years, MUVA KEMPTEN GMBH has experience in performing proficiency testing studies and in the applied statistics. MUVA KEMPTEN GMBH cooperates with a number of national and international working groups and is – since a long time – close with quality management and analytical quality assurance.

AOAC INTERNATIONAL food safety experts have adopted LactoSens^®R for measuring low levels of lactose in dairy products as a First Action Official Method of Analysis^SM during a meeting of the AOAC INTERNATIONAL Expert Review Panel for Low-Lactose Methods on January 15, 2020.

Measuring trace levels of lactose accurately is technically challenging and can increase costs for dairy producers because time-consuming testing processes effectively shorten shelf life. LactoSens^® test kits, were developed as a fast and easy alternative to the standard reference method using high-performance anion exchange chromatography, a technically complex technique which is mainly performed at external accredited laboratories.

LactoSens^®R Biosensor Assay Kit was evaluated against AOAC INTERNATIONAL’s Standard Method Performance Requirement (SMPR^®) 2018.009, which details the requirements for testing mono- and di-saccharides in milk, milk products, and products containing dairy ingredients that are low-lactose or lactose-free. The full study “Determination of Lactose in Low-Lactose and Lactose-Free Milk, Milk Products, and Products Containing Dairy Ingredients – LactoSens^®R Amperometry Method” will be published in Journal of AOAC.

We are pleased to announce that our new LactoSens^®R  user-friendly lactose assay kit for all lactose-free and low lactose milk products is available for purchase from our distribution partners Chr. Hansen A/S and Optiferm GmbH.

LactoSens^®R Reader is an improved device for stable and robust results providing more user friendliness e.g. through an included QR code scanner, automatic sample detection and the possibility for internal instrument QC with the calibration device.

The recently accepted NordVal International validation assures that LactoSens®R lactose biosensor assay kit performs with high accuracy and specificity down to detection limit of 0.008% lactose. All characteristics are found to be in compliance with claims, demonstrating equal performance with the reference method HPLC (ISO 2262 IDF 198).

External validation studies have been performed to prove that the biosensor assay kit LactoSens®R can be used to determine residual lactose in milk samples with a fat content of up to 36% as well as in fermented milk products like yoghurt, cream, sour cream and curd. Furthermore, it was approved that the sensor is also applicable to lactose-free flavored yogurts and milk drinks (e.g. coffee, cacao, fruits). In addition, it was verified that the sensors are stable for at least 3 days storage at 30⁰C.

The external certification by NordVal makes LactoSens®R the perfect choice for product release, process optimization and product development. More about LactoSens®R…

The international dairy technology platform ‘Dairy Technologist’ describes our LactoSens biosensor as a ‘Rapid Computerized Lactose Content Determination Method’ that can be adopted for both industrial and artisanal use. Considering the importance of dairy products as a means to fight world hunger and malnutrition, LactoSens can make a significant contribution in developing countries with a high prevalence of lactose intolerance.

DirectSens started a cooperation with the laboratory of Prof. Dietmar Haltrich at the VIBT BOKU for the project „StaREliS – Stabilisation of Redox Enzymes for long-term implantable Sensors”.

StaREliS aims to elucidate the deactivation mechanism of redox enzymes, which should serve as the basis for the development of stable enzymes for long-term biosensors.

The project is funded by a Bridge grant from the the Austrian Research Promotion Agency (FFG).

From the dairy industry point of view, IDM stresses the need for a precise, fast and easy method of on-site measurement of residual lactose – to bring it down to the recommended 0.01% lactose-free threshold. This has been made possible thanks to the technical breakthrough of LactoSens^®. The recent NordVal validation of this method against the reference method for lactose determination allows dairies to easily integrate LactoSens^® into their certified quality management system: This method’s high levels of accuracy, specificity, stability, and reliability have proven to be in line with the ISO 17025 standard.
