My thesis in 180 seconds (MT180)

"L'experimentarium"

Louise RAMOUSSE is a young researcher in chemistry and microbiology passionate about the taste enigma of wine. She carries out her investigations within the PAM lab in Dijon dedicated to food sciences.

Its objective is to explore the role of fat, also called “lipids”, in the production of wine and its aromas compounds. To do this, Louise is seeking to understand how the lipids present in grape juice are consumed by yeasts, living organisms essential for transforming the juice into wine. She strives to reveal the influence of this diet on the aromas compounds present in the wine.

Thierry Tran is a young researcher in the PAM lab in Dijon dedicated to food sciences. His team mainly works on wine, but Thierry is interested in another fermented drink: kombucha. This natural lemonade is obtained by transforming a sweetened tea infusion by a community of microorganisms. However, the behavior of this community can be unpredictable and lower the quality of the product.

Thierry seeks to better understand the interactions between microorganisms to help kombucha producers to control its production.

Tiffany Bellanger is a young researcher in the PAM lab in Dijon dedicated to food sciences. His team studies the microbes that live in wine, including how some are useful in making the drink.

Tiffany is interested in the bacteria Oenococcus oeni which plays a key role in the making of wine. She is studying the strategies that this bacteria uses to survive when its living conditions become difficult. She is particularly interested in knowing how this bacteria strengthens the membrane on its surface thanks to a protein that it produces.

Florian is a young researcher in food chemistry in the PAM lab in Dijon dedicated to food sciences. His team is particularly interested in wine and its evolution during storage. 

Florian tries to improve the conservation and quality of wine. To do this, he uses natural products rich in antioxidants that he adds during the making of the wine and observes their effect on the aging of the wine. By studying them, he seeks in particular to determine how they improve the conservation of wine.

Understanding food moulds for better control

Fungi are everywhere. These microscopic creatures possess extraordinary powers, such as the ability to withstand extreme environmental conditions.

PAM lab is trying to understand them better in order to improve their resistance to preservative treatments on the one hand, and to better destroy pathogenic fungi on the other. These discoveries could revolutionise agriculture in the decades to come …

Non-saccharomyces yeasts in wine: something new for taste and the environment

What lies behind a good wine? And behind a "piquette"? The taste of wine is not a matter of chance. It is the result of a multitude of environmental factors and processes, both natural and otherwise.

Immerse yourself in a research laboratory with its own winery to find out more about yeasts and their influence on the aromatic profile of wines. The basic aim is to mitigate global warming and reduce the use of sulphites, the preservative with such a bad reputation, through natural fermentation processes.

Plant proteins: a global issue, a challenge for PAM lab

Plant proteins are emerging as an alternative to animal proteins.

By 2050, there will be almost 10 billion human beings on Earth. To feed the planet, we will need to meet a growing demand for proteins. That's why UMR PAM is focusing on plant proteins. Peas, beans, lentils... all natural sources that can be used to produce protein-rich plant foods. How do they do it? What difficulties do they encounter? What does a food made from plant proteins look like? Would you like to try an ice cream made from pea flour?

Sulphur-free wines

Demand is growing for technical tools to produce wines with reduced or no sulphite content. Among these tools, bioprotection makes it possible to reduce or dispense with sulphites during the pre-fermentation stages. A summary of the many trials carried out in different structures will be presented. Various indicators have been monitored, such as the implantation and level of colonisation of bio-protective strains, the impact on indigenous populations in the pre-fermentation phase and, finally, the impact on the wine's analytical and sensory parameters. Lastly, these various trials make it possible to estimate the limits of bioprotection.

 

Vines on campus?

Did you know that there are vines on the Dijon campus? Most students walk past them every day without even noticing them. But what are they doing there? And do they produce wine? Marion, Zoé and Charlotte set out to find out.

 

Food packaging open courseware for higher education and staff of companies

FitNESS 2.0

Open courseware on responsible food packaging

Food packaging is often necessary or even essential for protecting food, keeping it safe and thus preventing substantial food losses. It can help to enable the preservation, transportation, distribution, and preparation of food. However, food packaging today is strongly associated with both environmental risks and health risks for consumers. To help packaging professionals address this challenge, the FitNESS platform was created to provide both general and in-depth training courses on the design of responsible food packaging. This includes learning to optimise the many, sometimes contradictory, criteria across all aspects of food packaging from its production and use through to its reuse, recycling, and disposal.
