Speclz SAS is happy to announce that we have our first website to present you our company, our product and our team. We are specially proud about Lucie, our gelation analyser.
At Speclz, we will provide solutions tailored to customers needs. In dairy applications, we can observe three major challenges.
- The impact of seasonal and climate changes. While the first one is well known, and dairy producers know the impact of winter and summer on the milk quality, extreme heatwaves and droughts and varying feeding behavior have unknown impact on the milk with consequences on the dairy product quality. [1]
- The need to reduce the company’s impact on environment, such as carbon footprint reduction.
- Finally, consumers are asking for more healthy food, such as protein-enriched, low-fat or vegetal products.
To face these challenges, actors in the dairy applications must improve:
- The processes to obtain a higher yield, while reducing waste.
- Optimize recipes with new ingredients, starters, proteins, rennets,…
- Bring new vegan alternatives on the market.
To help the dairy industry in this context, we propose Lucie, our newest member. She is conceived for characterising gelation, especially of milk-based products. She uses Multi Speckle Diffusing Wave Spectroscopy (MS-DWS)[2] to study the particle mobility. A laser light is sent into the sample, backscattered several times by the fat globules and protein particles. The backscattered light gives rise to interference waves, which are also known as speckle images. These images are captured by a camera. The image evolves in time as the particle are moving in the sample. A liquid sample with fast moving particles will give fast changing speckle images, whereas a solid sample with particles that are bond, will give speckle images with a lower change rate. Watch our short video to learn more about MS-DWS here.
The samples are placed in a measurement cell, in which gelation is directly performed. The measurement is done in real time, without interfering, thanks to the optical method. Finally, Lucie offers multiple positions, that allows to measure up to 4 samples simultaneously.
Lucie will maximize potential, while minimize waste. Her strengths are:
-
- High accuracy thank to the highly sensitive MS-DWS technique that measures particle mobility in the nanometer scale.
- High productivity due to the 4 measurement positions and multiparameter analysis.
- Easy handling without dilution, a 1-click smart software.
- Easy interpretation with programmable SOP, automatic gel point determination and characteristic gel parameters.
All information on Lucie from Speclz and how she can help you in characterising gelation, can be found in the brochure here.
