When fresh produce like salad products are processed, the disinfection is often performed by adding hypochlorite solution to the wash water.
Several standards state this must be maintained at 50mg/L or greater concentration - a very high level in terms of measurement for quality control.
Palintest offer two methods which are able to detect chlorine at such high levels for ongoing quality ...
Peroxides are the primary products of oil oxidation. Their identification gives us useful information about oil conservation and rancidity. The Hanna Photometer for the determination of peroxide value in oils allows fast and and simple analysis in accordance with the EC 2568/91 method. It is an auto-diagnostic portable microprocessor meter that is based on a special tungsen lamp and a na...
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....
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.

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...
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...
The Horiba LAQUA twin meters are best suited to a range of different sample types:
1) Immersion
When in the lab you can test an a beaker. Ensure the sensor guard is open.
2)Â Scoop
Use as a scoop to test water for example from a river
3)Â Drops
LAQUA Twin meters can measure sample volumes as low as 0.05ml. Place a drop of the sample onto the sensor with a pipette.
