Titration, a fast check for food grade oil quality

Cooking tasting a little off? Your oil may be the cause. From the obvious uses in frying food, to the small amounts added in baking recipes, oils are important to our diet and provide the basis for cooking in a range of cuisines. Rancid oil? One thing we don’t want...

Preserving food is a fine line to manage!

Longer shelf life, yes please! At what cost? Processed foods contain a range of chemicals to improve the look, texture, taste and shelf life of the products. Polyphosphates, or phosphate salts, stabilize the pH of foods and prolong shelf life. Polyphosphates are also important for treatment of ground water. While...

pH and acidity in wine…and other beverages

Look around in any winery or beverage manufacture and you will find a pH meter. In larger ones, you will also find a titrator. Why? Simply because pH and acidity have such a strong influence on the taste of wines and flavoured beverages that monitoring both is essential to ensure...

Electrochemistry in the quality control of food and beverage packaging

The shelf life of foods and beverages depends to a great extent on the packaging material. Metals are ideally suited for this purpose, as they can be coated with different passivating food-grade layers. Nethertheless, electrochemical measurements such as impedance spectroscopy (EIS) are required to monitor the integrity of the sealing...

How much artificial sweetener is too much?

Avoiding sugar has become a religion to many. This has been assisted by the rise in artificial sweeteners available and the number of products advertising “sugar free.” One of the common sources of artificial sweetener is the stevia plant, from which steviol glycosides are produced. For successful analysis, it is...

Salt analysis. Fast. Reliable.

When salt is discussed, in relation to food, the sodium content is really of concern. For large scale contract labs, this can easily be analysed by AAS or ICP, however these techniques require staff with analytical backgrounds and relatively high operation costs. Smaller food producers or large-scale manufacturers without a...

Fast analysis for busy laboratories

“Chromatography is a slow analytical technique…..” “If it doesn’t use gradient elution it won’t be fast enough……” “I can’t wait that long for results…..” These are all statements that have been synonymous with ion chromatography for a long time, but are they really true? There have been a let of...

Consolidated beer analysis

For a long time in analytical laboratories, the goal has been automation. Automation removes the human factor from sample preparation and analysis, whether it is 4 am, 11.55 am or 5 pm, sample are handled the same way. The disadvantage of automation has, historically, been each analysis requiring a sample...

Consolidated beer analysis on a single platform

Beer analysis on a single platform Feldschloesschen AG, Switzerland’s largest brewery, has consolidated the quality control of their product on a customized Metrohm system. Comprehensive beer analysis used to be fragmented and distributed across several analyzers in the Feldschloesschen QC lab and is now conveniently performed on a single, modular...

Keeping milk fresh, it is a fine line to tread!

Lactoperoxidase process Slowing the lactoperoxidase process is a key way of prolonging the shelf life of milk. Unfortunately, the simple way of doing this, adding thiocyanate to milk, can have a negative effect on the thyroid, especially for infants. Along with iodine and perchlorate, thiocyanate levels in milk have a...

Without a representative sample, quality control analysis is a guessing game

Taking the effort out of preparing solid samples for moisture, salt and general titration analysis The best way to get a representative sample? Automate the sample preparation process! The Polytron homogenizer provides programmable sample preparation of all foods, from hard candies to meats and jams. The high speed rotation of...
