Analyses of yeast assimilable nitrogen (YAN) and gluconic acid for optimum management of alcoholic fermentation

As is known, due to global warming, we are witnessing increasingly adverse and difficult weather conditions. The rise in average temperatures is in fact causing an increase in the frequency of hot and dry vintages alternating with rainy and cool years. In difficult climatic conditions, in addition to the usual analysis of sugar, total acidity, pH and acetic acid, yeast assimilable nitrogen and gluconic acid are the fundamental parameters available to the oenologist to better manage the fermentative process, an essential starting point to obtain a quality wine. What are yeast assimilable nitrogen and gluconic acid? How can these analyses affect alcoholic fermentation? For further information on these important themes you can download the article: VINIFICATION IN THE ERA OF GLOBAL WARMING

Fried snacks: the knowledge of the oxidation state to improve the Shelf life

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
