How to choose a Memmert Climate Chamber?

A climate chamber (also known as a test chamber, humidity chamber and environmental chamber) is used to simulate a range of environmental conditions. They are widely used in lifespan and stability tests across multiple industry types including pharmaceutical, cosmetics and aeronautical engineering. Memmert offer a comprehensive range of climate chambers, with different test parameters such as ...

Measuring the pH of bread dough

In the food industry, pH monitoring may be required during the production or pre-production process for a number of reasons including for microbe monitoring and taste purposes. In baking and bread-making there are a number of reasons why you would wish to know the pH - having a low pH in sourdough inhibits growth of pathogenic bacteria and in bread dough pH control agents (preservatives) may be...

Using moisture balances to test food quality

Moisture and weight assessments provide critical information about content, quality and safety in food. Using a moisture balance will increase food safety in a lab by indicating the presence of microbes as well as levels of acid and water. This can give an indication of how fresh the food is and validate sanitation procedures. A moisture balance/analyzer/meter consists of a weighing unit...

Which moisture balances are glass free for food manufacturing sites?

Moisture balances offer a fast way to analyse the moisture content of food samples, and are ideal for quality control checks during production or before final product release. However some of the balances contain glass parts, which presents a hazard in food manufacturing areas. We've found two moisture balances that do not contain any glass, making them suitable for food production areas....

Determination of Calcium in Milk using a Flame Photometer

The team at Jenway have described a method to determine calcium level in milk samples using their PFP7 Flame Photometer. Calcium is usually present at about 120mg per 100ml milk, or 0.11%, but this varies with the type. The method and equipment required are summarized below to test milk samples for calcium content.   [caption id="attachment_10449" align="aligncenter" width="422"] ...

A quick test for correct pasteurisation in milk

Pasteurisation (or pasteurization) is used in a range of liquid food and drink products to kill bacteria, making it less quick to spoil. In milk this process is especially important - a recent study by the Centre for Disease Control (CDC) in the USA showed that the risk of a disease outbreak was 150x greater from unpasteurized or "raw" milk than pasteurized milk. [caption id="attachment_8...

How can I measure Salt in food?

Sodium is a mineral required by the body for normal functions, but excessive intake can cause high blood pressure and hypertension. This has lead governments and regulatory bodies to focus on monitoring the levels of salt in foods in order to reduce the risk of these health affects. Canned foods are of particular concern as these often contain relatively high levels of salt. The Horiba La...

Which digital thermometers are recommended for food manufacturing environments?

Q: I work in food manufacturing and need a digital thermometer for quality control checks. The environment in the factory can be high humidity, may cause the thermometer to be splashed with liquids and may mean people have to use the thermometer with wet hands. What model would you recommend? [caption id="attachment_7409" align="aligncenter" width="204"] The Hanna Checktemp 1 - a simple,...

How can I measure the pH of food?

Measuring pH in food is a useful indicator of consistency over batches for quality control but can also be used to monitor foods where the pH changes over time - for example in yogurt production, brewing or to test the freshness of foods. Standard pH electrodes will often struggle when used in food samples, as the reference junction becomes blocked the reaction time will get slower and event...
