In the 2021 oil season we saw a low level of oil production. How was the quality of the oil produced in Tuscany in 2021? How important is the quality control of olive oil?

If in many respects 2020 was dramatic, at least from the point of view of “oil”, it reserved some satisfactions for farmers and for operators in the sector in general: the quality of the oil released from the mills was excellent in general throughout Italy, while productivity was more contracted in the south and more abundant in the centre north. What was the influence of the climate? In the last 10 years, how much have climatic conditions influenced the quality of production?

Taking a cue from the various sets of research carried out on the possibility of determining the state of ripeness of the olives, the researchers of the CDR chemical laboratories conducted a study with the aim of developing a rapid and simple system for obtaining indications on the degree of ripeness of olives, useful for identifying the best time for harvesting.

2019 another not exceptional oil season from various points of view: the results of the analysis of Tuscan oil confirm the difficulties of the sector that have persisted for several years now due to the difficult climatic conditions.

The 2018/2019 oil campaign can now be considered concluded for this year and, as in other years, we are able to comment on the results of the analyses carried out on a few dozen samples from various areas of Tuscany. Furthermore we have carried out a small study to learn more about determination of the appropriate harvesting period in the case of a heterogeneous olive grove that has several cultivars.

The beginning of the season was rightly perturbed by forecasts of reduced production which came true. In particular, in a few central Italian region, productivity was very low, whereas at a national level, production was below average, despite being slightly up compared to the previous oil production season. What about quality?

A low productivity and high quality of the oil have been foreseen at the launch of the 2017 oil season. In the chemical laboratories of CDR we started to analyze the oil samples of the 2017 season. We see the first results of the analysis of the oil. Are the forecasts respected?

The characteristics of ingredients are fundamental in olive oil production. The olive pressing process also plays a key role in determining a high quality product such as extra virgin olive oil. We will examine how it is possible to increase the quality of extra virgin olive oil produced, by constantly monitoring certain chemical parameters, while providing descriptions of detection methods used.

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

An analysis of Tuscan oil quality in 2016. In particular, the influence of climate and the milling plant was studied using the results of chemical analyses carried out at CDR laboratories, using the CDR OxiTester analysis system.
