Heating dough during mixing brings key informationIn a recent study conducted with one

of our business partners, we showed

the MIXOLAB was very effective in

discriminating non-conforming fl ours.

Several samples were outlined, despite the

fact that they met standard specifi cations.

Our business partner was facing a common

scenario: the fl our samples tested were in

their specifi cations book (hydration and

cold mixing), but were causing problems

on the production line.

With the MIXOLAB, a very precise

identifi cation of the fl ours is possible.

Although the samples have a very good

repeatability on the ‘‘cold’’ part, (hydration

index of approximately 8 and kneading

index between 5 and 6), they behaved

very differently once the dough is heated

up.

The graph above shows a fi rst area

corresponding to the ‘‘conforming’’

part, while the second area shows very

heterogeneous behaviors. In this case,

heating the dough brings key information

about amylase activity and starch

properties.

These good results are not a surprise.

It is a known fact that starch quality and

starch behavior during cooking infl uence

crumb structure, color and shelf life of the

end product. Therefore, not controlling

this essential component means having

an incomplete quality control of the raw

materials.

The exhaustive information obtained

from the MIXOLAB test brings better

fl our quality control and, as a result,

optimum discrimination of non-conforming

products. It is then possible to implement

precise specifi cations, easy to control, for

the benefi t of all the people in the cereal

industry.

Infraneo Jr and Sr certifi ed in KazakhstanChopin Technologies work with national and international authorities to meet local regulatory requirements.

Having experienced great success in Kazakhstan, CHOPIN Technologies has initiated a certifi cation process for Infraneo NIR analyzers with the institute of metrology, KAZINMETR. An audit was conducted on the Villeneuve la Garenne site in December 2011. All aspects of production, preparation and standardization were examined in details. An advanced set of tests to check system repeatability, reproducibility and robustness confi rmed a very high performance level, in full compliance with current Kazakh and European regulations.The NIR system range manufactured by CHOPIN Technologies is now offi cially approved by the authorities and can be used in grain business transactions in Kazakhstan.

CHOPIN TECHNOLOGIES moisture meters: closer and closer to the reference value

To ensure measurements corresponding to successive harvests, CHOPIN Technologies has been using for several years a system to monitor the moisture meters accuracy.

Every year, more than 400 samples of 9 different types of grains (common wheat, durum wheat, barley, rapeseed, rye, sunfl ower, corn, soybean, sorghum) are collected from storage organizations in all the major French agricultural regions and analyzed by CHOPIN Technologies, as per the reference method (EM10 oven as per ISO 712). The samples are also run on standard moisture meters to monitor their consistency in results against the reference value.

All these data are used to accurately defi ne any adjustments potentially required to be incorporated on systems in the fi eld to ensure the accuracy of the results on the entire installed base (see graphs). These adjustments are subsequently applied by members of the CHOPIN Technologies-approved service network during annual system inspection.

In France, the results from this monitoring are offi cially published by the organization responsible for the legal traceability of moisture meters: LNE (French National Metrology and Testing Laboratory). For users, this represents a guarantee of quality and reliability.

The German fi rm, which is specialized in fl our enhancers and correctors, describes itself as an «enzyme designer» and has continuously made sure that its laboratories remain at the cutting edge of technology. In this context, a joint project was set up with CHOPIN Technologies in early 2011.

As part of this program, which also includes application developments, the German laboratory in the Stern Wywiol (the owner of Mühlenchemie) technology center located in Ahrensburg near Hamburg was recently equipped with the latest generation of CHOPIN Technologies systems. Currently in the process of expanding, this technology center, made up of various application laboratories, will shortly cover up to 3000 m² for an investment of over €5 million.

Mühlenchemie equips its central laboratory with the latest generation of CHOPIN Technologies systems.

CT Center celebrates fi rst year anniversary

The CT Center is a training center specially designed for users of CHOPIN Technologies instruments. Opened in 2011, the center has already trained more than 60 persons in 6 sessions given in English, Spanish and French, devoted to the Mixolab, Alveograph and CD1 mill.

First review:

Including all the aspects of analytical testing (methodology, maintenance, handling, standardization, applications, etc.), the training offers participants everything they need to maximize the use of their CHOPIN Technologies instruments. The conference room presentations, laboratory procedures and maintenance workshop brought a lot of exchanges between the participants and the experts.

Attending the CT Center also offers an opportunity to discover the sometimes not so well-known scope of possibilities offered by your systems, such as the use of Alveograph at adapted hydration or corn analysis with the Mixolab.

In order to evaluate the quality of the training, participants are asked to complete a questionnaire at the start and end of training. This has shown a very signifi cant improvement in knowledge. It is also worth noting that 25% of trainees rate the training as ‘‘very good’’ and 75% as ‘‘excellent‘‘.

Attending the CT Center also offers direct contact with the teams at CHOPIN Technologies. Further sessions are scheduled throughout 2012. You should have no problem fi nding one that suits you! For further details and to register, visit http://www.chopin.fr/page_ct_center.php

«Close cooperation with world-wide experts in grain, fl our and dough analysis, such as CHOPIN Technologies, allows Mühlenchemie to be at the cutting edge of innovation in its core business» points out Lennart Kutschinski, the company’s Managing Director.

Chopin CD1 mill – Not only for wheat.For quinoa too!

SDmatic – The citric acid optionStarch damage analysis with SDmatic complies with international standards (ICC172, AACC 76-33.01 and NF V03-731). These standards mention the use of boric acid, a substance recently classifi ed as «reprotoxic» 2 (CMR) by the European Community.

Even though the risk associated with the use of boric acid is extremely low (due to the very small amount of substance used), a new SDmatic method replacing boric acid with ascorbic acid has been developed by the CHOPIN Technologies Applications laboratory. It is simply necessary to use 1.5 g of citric acid instead of 3 g of boric acid and recalibrate the system.

The solution is simple, suitable for immediate use and offers identical performances. Furthermore, the applicable standards are still valid.

Quinoa, a pseudocereal originating in the Andes, has seen a new interest since the early 2000s. Its nutritional qualities (rich in essential amino acids, Mg, Fe, and Cu) are the key to this success in developed countries where it is classifi ed as a ‘‘healthy product’’.

However, the husk of quinoa grains is rich in saponin (surfactant compound) which should preferably be removed before consumption.

Using a simple 4-step protocol (conditioning, milling, reduction 1 and 2), the CD1 mill can be used for milling quinoa with an extraction rate of more than 70%.

This method does not require any modifi cation of the standard CD1 mill.
