What you can analyze

With CDR FoodLab® you can obtain in a simple and rapid way a complete control on the oxidation state of hard shelled dried fruit, seeds and other similar solid samples.

Tests available for nuts and seeds

How to determine the oxidation state of nuts in 3 simple steps

Chemical analyzes to determine in 3 steps rancidity of dried fruit easily and quickly without toxic solventsWith the CDR system, you extract the oil to analyze with a simple mechanical treatment.

Thanks to the Multitasking Mode, on the oil extracted you can determine in 5 minutes Acidity, Peroxide Valueand p-Anisidine Value, abandoning the use of toxic solvents, extraction hoods, complex analytical instruments and complicated methods.

Several comparative studies have given evidence that the accuracy of the results of oxidation state tests is in line with the accuracy of the results yielded by the reference methods, while CDR FoodLab® is much easier to use and provides the requested results in reduced testing time.

What you can analyze more

CDR FoodLab configurable for analysis of foods: oils and fats, eggs and egg products, milk and dairy products, tomato and derivativesThe CDR FoodLab® system for the determination of the oxidation state of hard shelled dried fruit can also be used to test any type of vegetable and animal fats and oils. Moreover, it can be configured to perform chemical analyses on eggs and egg products, milk and dairy products, tomato and tomato derivatives.

Save your time in testing nuts oxidation state

CDR FoodLab® can analyze micro-quantities of samples

  • No calibration procedure or maintenance operation is required.
  • The apparatus does not necessarily need to be used in a laboratory, but can also be used on the production line
  • Can be used by personnel without specific lab tech experience
  • Results are obtained in just a few minutes.

Used together with the dedicated extraction system developed by CDR, the CDR FoodLab® analysis system is particularly suites for all companies that are active in the field of nut production, processing and packaging.

In fact, the leading companies in this market sector have also chosen CDR FoodLab® because it allows to rapidly assess the quality of nuts abandoning traditional testing methods that foresee the use of toxic solvents (Soxhlet).

A true testing laboratory that comes in a complete, intuitive and reliable equipment

Complete, intuitive and reliable equipment to Determining the rancidity of nuts without solvents CDR FoodLab® is a true analysis laboratory. We have developed it to perform easy and fast chemical analyses even on the production line without the support of personnel with specific lab tech experience.

CDR FoodLab® fine tunes traditional testing procedures, making them faster and easier, while guaranteeing accuracy standards in line with the ISO/AOCS reference methods.

Compact and handy, it is composed of:

  • an analyzer based on photometric technology equipped with state-of-the-art LED emitters, available in 2 versions
  • a kit of pre-vialed and ready-to-use reagents, specifically developed by our research laboratory to fine tune analytical methods and avoid any contact with toxic or carcinogenic substances
  • pipettes that allow for the collection of the correct volume of sample.

Our device comes from a family of fast and reliable testing systems that we have developed and manufactured to perform food and beverage quality controls during the production process.

The ‘help’ function makes your tests easier

The system is reliable, fast and intuitive. It is so simple to use that anyone can run a test in total autonomy as if they were skilled personnel. Just a few steps suffice to perform the analyses and, if there is ever a doubt, the HELP function will lead you through the process by displaying detailed instructions.

Food quality controls for nuts: product batch rancidity assessment

the complete extraction and analysis system offered by CDR FoodLabNuts are very rich in fats. That is why free fatty acids and peroxide value tests are constantly run by businesses operating in the field because they provide valuable information on the rancidity of fats and oils.

Here is an insight on the chemical features and methods of official testing systems compared with the techniques designed and fine tuned by CDR to efficaciously monitor the natural degradation and rancidity process of batches of product

Evaluation Report

Comparison study between CDR FoodLab® analytical methods and reference methods – Campden BRI

Comparison study between CDR FoodLab® for oils and fats analytics methods and reference methods made by Campden BRIThe international reference laboratory Campden Bri has trialled the CDR FoodLab® to establish whether it could meet the requirements for analysing a number of important food quality parameters. assessment of the ability of the CDR FoodLab® to analyse for Anisidine Value, Peroxide Value and Free Fatty Acid content showed that the instrument gave comparable results to the reference methods with very high correlation coefficients suggesting good accuracy of results.

Validation study of Free Fatty Acids and Peroxide Value determination made by Universities in Republic of Korea

FFA and POV test validation by universities of Republic of KoreaThe reliability and availability of CDR FoodLab® system for determining acid value (AV) and peroxide value (POV) were assessed during the hydrolytic rancidification and lipid oxidation of edible oils. 

The CDR FoodLab® system based on spectrophotometry was compared to the official methods (ISO 660 and 3960 protocols) based on manual titration employing the standard mixture for the simulated oxidation models and edible oils during the thermally induced oxidation at 180°C.

Considering ISO protocols with a probability of human error in manual titration, the rapidness and simplicity of the reagent kit based on spectrophotometry make it a very good alternative to monitor the lipid oxidation of edible oils and lipid-containing foods. [More…]
