Lecithin is a natural ingredient frequently used in the food industry for its emulsifying and stabilizing effects. Lecithin is an essential component in chocolate and confectionery production as it contributes to the smooth melting of chocolate, improves the softness of chewing gum, facilitates the cutting of caramels and minimizes oiling-out of toffees.
Meeting Food Manufacturers’ Demands One of the largest food production companies worldwide produces over 1000 ingredients for food applications alone. Their confectionary division makes several grades of lecithin to meet food manufacturers’ demands for different functionalities and company researchers have developed a new process for manufacturing lecithin in a powdered form. The moisture content of the lecithin must be tightly controlled to ensure that the powder remains easy-to-mix and can be stored well.
Efficient In-Process Control with the HB43-S Food production companies typically run their operations 24 hours a day. In one company, their quality control labs take samples to be tested from production lines every two hours making fast moisture determination the prerequisite for handling such a large number of samples. Moisture Analyzers are very efficient as they use infrared drying technology to heat up samples rapidly and homogeneously. Samples lose water very quickly giving rise to very short testing times (typically less than 15 minutes) and the integrated balance monitors the sample weight and the moisture content which are recorded continuously. All relevant measurement data is documented in GMP/GLP compliant protocols eliminating transfer and calculation errors.
Based on their good experience with several HB43-S instruments at one plant, they are now standardizing their labs with METTLER TOLEDO Halogen Moisture Analyzers. The AOAC reference method* is now only used for final product inspection as the HB43-S Halogen Moisture Analyzers are a highly efficient and safe solution for monitoring moisture content throughout all other production process stages.
