Weighing and Analysis in the Laboratory

Key parameters in quality controlFor their confectionary products, Ferrero uses many raw materials such as flavors, alcoholic liqueurs or fondants. Density and refractive index measurements allow quick and unambiguous product identi-fication and serve to determine concen-trations in binary or tertiary mixtures. Ferrero typically analyzes around ten samples per day and performs multiple measurements per sample.

Numerous benefits for FerreroFerrero have combined density and re-fractive index determination with one instrument for added operator conve-nience and increased lab productivity. The DR40-SC1 automated system from METTLER TOLEDO eliminates fiddling with syringes and lengthy manual clean-

Italian chocolate maker Ferrero is famous for many brand products. For

example, “Kinder” chocolate and Nutella chocolate spread are well known.

The METTLER TOLEDO combined density and refractive index instrument

DR40 lies at the heart of quality control operations.

Density and Refractive IndexEnsures the Smooth Taste of Nutella

ing operations. Instead, operators simply place the sample in a glass vial onto the SC1 sample delivery unit. The instrument pumps the sample into both measuring cells, adjusts the temperature to a set val-ue, prints results to the attached printer and thoroughly cleans the measuring cell ready for the next sample.

Leading brands’ manufacturers cannot compromise on product quality as brand assets are soon devalued by dissatisfied con-sumers. Ferrero maintains this paradigm by choosing a METTLER TOLEDO combined density and refractive index instrument. Besides optimizing product quality, they also believe that productivity is improved.

l Statistical Quality Control With the new SQC-XP Balance

Where complicate handling is part of the SQC process, Excellence Plus XP balanc-es will be a revolution. With a big color touchscreen display and the possibility to operate the balance hands-free, thanks to the SmartSens or the ErgoSens, SQC-XP balances allows to store up to 100 articles. The configuration of up to 8 users enables you not only to choose your favorite lan-guage but also to personalize the display. XP is so intuitive that you can quickly use it without any instruction manual. The weighing range of SQC-XP stand-alone system goes from 1µg up to 64kg!

As required by authorities, the process has to be fully documented and trace-able, which is easily done with the SQC-XP offering error-free documentation. By using the optional Bluetooth interface, you can use a wireless bar code reader or even print your results wirelessly. With violation check, the balance will verify for you if your sample is within defined tolerances and gives a warning for each measurement out of tolerances - for more data security.

The transparency of the filling process al-lows immediate reaction and assures that unnecessary overfilling is avoided, which helps save cost. SQC-XP is the most com-fortable way to have minimal overfilling and no underfilling while random sample series and their statistical values are com-pletely documented.

To meet regulatory requirements, statistical quality control (SQC) is required for net con-

tent control of pre-packages. These checks have to be fast, reliable and easy to carry out.

A stand-alone system often is the best solution for small productions because of simple

operation and low training and maintenance costs. With its new SQC-XP software, METTLER

TOLEDO use the performance of the Excellence Plus XP balance to offer an easy to use

quality control software where a PC is not necessary.

The best French fries in townDeep-fried and golden brown is how ev-erybody loves them. Most restaurants rely on frozen, pre-fried French fries for the sake of convenience and quality. A renowned, innovative producer of high quality French fries is the Swiss company KADI – supplier of the “KADI SUPER-FRITES”. These French fries are not only super crisp, but also super profitable for the chef, thanks to a patented coating, the “Knuspermantel”. Selected raw mate-rials, careful processing and continuous quality control are KADI’s recipe for high quality fries. The Swiss company is BRC certified.

The Secret of Crispy French Fries – an Optimal Moisture Content

Nowadays, potatoes are consumed in many ways. In terms of popular-

ity, French fries clearly are first choice. The Swiss company KADI

knows all the secrets of manufacturing mouth-watering fries.

Besides top quality ingredients and controlled processes, the

right moisture content is key for perfectly golden and crispy fries

– a good reason for KADI to rely on METTLER TOLEDO moisture

analyzers.

Fast results for maximum crispnessThe process of turning potatoes into frozen French fries starts with washing, peeling and cutting. The potatoes then undergo various heat treatments includ-ing blanching, drying, pre-frying, cool-ing and freezing. For taste and texture of French fries the moisture content plays a crucial role and is analyzed at several points during processing. Quality manag-er Niklaus Meyer explains the importance of moisture analysis: “Depending on the moisture content, the frying temperature is adjusted. Only optimized conditions give good quality fries. Potatoes contain-ing excess moisture would absorb too much oil and come out soggy.”

At KADI the halogen technology of the HR83 moisture analyzer has been cho-sen to ensure the quality of its French fries. ”The HR83 moisture analyzer is fast, easy-to-use and reliably delivers our results”, says Mr. Meyer, adding that an additional plus is METTLER TOLEDO’s periodic on-site maintenance and cali-bration service.

Liquid Fractionof Palm Oils

Palm oil and its liquid fraction, palm ole-in, are consumed in a wide variety of food products from instant noodles and crisps to cake mixes and snacks. The main sup-ply of palm oil is from Malaysia with a production level around 50% of the global demand. The use of palm oil accounts for over 25% of the total global supply and demand in the oil market.

Palm oil is readily digested, absorbed and utilized in normal metabolic processes. Like other vegetable oils, it is cholesterol-free. Having a moderate level of satura-tion, it does not require hydrogenation for use as a fat component in foods and as such does not contain trans-fatty acids.

Fractionation of palm oil Fractionation is a physical process that uses the crystallization properties of triglycerides to separate a mixture into two or more fractions. The two fractions obtained from the fractionation of palm oil after crystallization at controlled tem-peratures are palm olein (liquid oil) and palm stearin (solid form).

The DSC heating curves shown in Figure 1 were measured using the DSC823e and evaluated with the STARe software. The liquid fraction was calculated by partial integration of the melting peaks.

Differential scanning calorimetry (DSC) is a powerful

tool to characterize palm oil used in food products

and for processing. The following example highlights

how detailed information on crystallization and

melting behavior can help maintain product quality.

Fruit of palm oil tree

Liquid fraction of palm oil

Sample Liquid raction at 25 °C Temperature of last peak

Palm olein 94.9 % 37.7 °C

Palm oil 79.8 % 40.7 °C

Palm stearin 53.1 % 53.7 °C

Palm oils of different origin and fraction-ated palm oils such as palm olein and palm stearin exhibit different melting and crystallization behavior. The results show that the DSC823e can be used to charac-terize such oils and to obtain important information such as the liquid fraction at user-defined temperatures – to guarantee and maintain optimal product quality.

Titration in the Snack Food IndustryAcid and Chloride Determination in one Click

Acids and chloride are essential ingredients in the snack food industry and

have to be monitored continuously for a broad range of products. If these

two measurements are combined in the same sample series the operator

saves more than 50% of the time for sample preparation and instrument

operation.

Reduce your workload with combined analysesThe quality of different products in the snack food industry such as vinegar chips, ketchup, pickles and many more is moni-tored for chloride concentration not only to get the right taste but also because of health issues. In addition the acid content is measured for some of the products. In the ideal world these two analyses could be combined to one and started with just one single click resulting in time savings of more than 50%.

Increase lab capacity with just one clickMETTLER TOLEDO’s new Titration Ex-cellence line makes this dream come true. Titration analyses can be set up in methods with loops in a way that more than one task can be combined. First the acid content is determined and after a readjustment of the pH the chloride con-centration can be determined. Thanks to the unsurpassed user guidance it is easy to develop such customized methods from preprogrammed METTLER TOLEDO methods. The user manager allows the lab manager to protect validated methods

from unwanted changes and gives him the possibility to setup personalized Home Screens for each user. For repetitive tasks not only a single method but even sample series with combined titrations such as acid and chloride determinations can be saved as templates and linked to the Home Screen as Short Cuts. Once the user is logged in the only thing he has to do is to press the corresponding Short Cut and the whole analysis sequence is started with one single click.

Combine One Click Titration™ with system automationThe biggest benefit of the combination of these two determinations arises if the system is fully automated with a Rondo 60 sample changer. The only thing the operator has to take care of is to click the Short Cut and transfer sample identi-fication and sample size to the system for example with a bar code reader.
