The study “Improvement in nutritional quality and thermal stability of palm olein blended with macadamia oil for deep-fat frying application”, supported by Texas A&M University and published on the Journal of Food Science Technology, aimed to investigate the suitability of refined bleached deodorized palm olein oil (RBD POO) and Macadamia integrifolia oil (MO) blend as deep-fat frying substitute.

CDR FoodLab^® for analysis of Free Fatty Acids (FFA), Peroxide Value (PV), and Anisidine Value (AV) has been used for the study. The mentioned parameters has considered as indicators of the state of oil deterioration.

To obtain a high quality product, it is essential to continuously monitor frying oil. CDR FoodLab^® enables to control the quality of frying oil directly during the manufacturing stage with a fast, simple and reliable method, the ideal system to monitor the degradation of frying oil, cooking oil, waste oil.

People from 35 countries visited CDR booth at SNACKEX to see the innovative quality control methods for snack available with CDR FoodLab^®, the analysis system already used by snack industries worldwide. The most used application is the quality control of the oil during the frying process and the control of the quality of savoury snacks (fried chips, corn chips, etc.) as well as nuts (peanuts, hazelnuts, pistachios, etc…).

Snack foods are currently consumed by millions of people of diverse cultural backgrounds in many countries because they are tempting snacks if characterized by crispness, brilliant colour and flavours.

However, these products can undergo degradation processes, first of all, the lipid oxidation which causes rancidity and off- flavours.

There are several methods to test the shelf life of snacks and bakery foods, but CDR FoodLab® is the only one, not only to be a green method, but also, it is able to give an actual measurement of oxidative stability of finished products, in a simple and fast way.

Comparison between different methods

CDR will be at SNACKEX in Vienna the next 21st and 22nd of June. SNACKEX is the international event for the savoury snacks and snack nut.

We exhibit the CDR FoodLab® for the specific application on snacks: fried potato chips, extruded and pellet snacks, tortilla chips and the various types of snack nuts.

Patricia Balbiano, Crystal Filtration manager for Latin America, explain in the article how to use CDR FoodLab^® for the quality control of oils during frying process.
CDR FoodLab^® for fats and oils analysis has been presented in the last edition of Expo Botanas, the most important exhibition of snack in Mexico.

the analytical system for oils and fats was used during the study entitled “Analyses of the oxidative stability of deep-frying oils, carried out by the University of Hamburg and presented at the 6th edition of the Euro Fed Lipid Congress
