The history of beer spoilage bacteria and yeast detection.
Since several thousand years, lots of ancient cultures discovered the nice effect wet storage cereal might have by alcohol production — without knowing scientific details of the process. However, the beer production by trial and error was one of the first human-driven industrial biotechnological processes.

In one of our first videos in this R-BioTube Channel I talked about the importance of sampling. The quality of your sampling method contributes largely to the quality of your final result. Typically, more than your actual analytical method. But there is a second step that influences the quality of your result or the total analytical error: That is the sample preparation.
Vitamin B6, also named Pyridoxine, is the first vitamin we would like to introduce you in our vitamin series. In this video, by Ronald Niemeijer, you can learn more about the importance of this vitamin, food products that contain vitamin B6 and the risk of a vitamin deficiency.

The next generation: the Enzytec™ Liquid testkits for enzymatic food analysis – or what we like to call them, the „Yellow Line 2.0“. In this video, Ronald Niemeijer tells you more about the improvements of the Enzytec™ Liquid testkits compared to traditional methods.
Mycotoxin testing imposes unique challenges to analytical laboratories. Complicated matrices, inhomogeneously spread contaminations, very low levels are just a few challenges to be met. The importance of choosing the right sampling, method, sample preparation and analytical method is obvious. The use of certified mycotoxin reference materials as well as mycotoxin quality control materials will strengthen your quality assurance in mycotoxin testing.
Do you still pay so much for external analysis costs? Or do you have trouble with false-positive results or cross-reactions? You haven’t thought about in-house testing using real-time PCR yet? Being independent from external service labs? It is so easy. That’s see!
When testing for allergens in food, most laboratories use immunological methods such as ELISA. However, real-time PCR can provide distinct advantages. In this video, Ronald Niemeijer sums up what you should know about allergens and PCR.
Eggs are a popular ingredient in many dishes and processed foods — a challenge for allergic people. In order to protect affected people from the unintentional consumption of foods containing egg, a correct labelling on the list of ingredients is of great importance. In this video, Jasmin Wolf explains what to consider when producing egg-free food.
Real-time PCR has proved to be a reliable and efficient analysis method in many areas. For laboratories who have avoided up to now the investments for PCR analysis, the new compact RIDA®CYCLER now makes it easy to get started. In this short video, Ronald Niemeijer presents the instrument in more detail.
In industrial animal husbandry, animals are often treated with antibiotics, which may result in residues in animal products if used incorrectly. Consumption of contaminated food is a health risk. And there are more problems, as Ronald Niemeijer explains in this video.
Heavy precipitation during the flowering season favored the growth of mold in many regions this year, leading to mycotoxin contamination in the harvest – often even with several types of mycotoxins at the same time. In this video, Ronald Niemeijer explains how to analyze multiple mycotoxins simultaneously.
ELISA is a test method with many advantages: it allows fast and specific quantitative analyses while being efficient and easy to perform. However, before a laboratory can start with ELISA, certain equipment is needed. In this video, David Steinmann presents a small and innovative reader for ELISA plates, the RIDA®ABSORBANCE 96.
Brettanomyces yeasts cause the so-called “Brett“ off-flavor: an unpleasant smell of horse stable, leather, sweat or even urine. Early detection of a possible contamination is of great interest for winemakers. In this video, Ronald Niemeijer presents a fast and precise method for this.
In general, beer is not a likely habitat for microorganisms: the alcohol content, the low pH value, the anaerobic atmosphere, the hop bitters and the limited nutrient supply make beer a rather hostile environment. However, some bacteria have adapted to this environment. In this video, Ronald Niemeijer explains how to detect them.
Deceptive labelling, prohibited additives or the substitution of expensive ingredients with cheaper components: Food fraud is an increasing problem worldwide. In this video, Dr. Caroline Knoll explains how to detect meat adulteration.
Measuring the vitamin content of foods can be complicated. Smaller laboratories often avoid the effort and hire external labs for the analysis. But with the right tools, vitamin analysis can be done very easily and economically.
Salmonella is the most common cause of food poisoning in the EU with over 100,000 reported illnesses every year. In this video, Ronald Niemeijer shows you how to detect Salmonella contamination in an effective way.
In mycotoxin analysis, the reliability of a test result depends not only on the test system used. Representative sampling and appropriate sample preparation have a much greater influence.
The TANBead Maelstrom™ 8 Autostage in combination with the SureFast® Mag PREP Food is an automated DNA purification solution for food and feed samples. Bring productivity to your laboratory with the fully automated extraction instrument for different applications and matrices at the same time.
Marine biotoxins are natural chemicals that accumulate in fish and shellfish. They are triggered by certain types of toxic algae. The incidence will increase in the next few years, so it is important to analyse sea food. Ronald Niemeijer tells you more about.
Dairy products made from milk from other sources than cow are becoming more and more popular. In this video, Ronald Niemeijer explores the question of whether you always get what you pay for cow milk alternatives and how easy it is to test for adulteration.
