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.

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

The 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.

CDR and its American distributor have presented the new CDR FoodLab®at Snaxpo 2015, the most important event of the snack food industry, showing the features of the new analyzer and performing with it demo analysis on different kind of matrices involved in the production of snack food: from finished product to cooking oils, vegetable and animal fats, nuts, eggs and egg products, milk and so on.

CDR chooses Snaxpo for the worldwide CDR FoodLab preview. The new analysis system will be presented at the american Snack Food Industry trade show, identified with the most influential organization in the sector, the Snack Food Association. From 28th to 31st March at stand #226B is possible to see CDR FoodLab® and analysis demos.
