At Concentrol, we offer antifoam solutions for different industrial sectors, with a special focus on the food industry. In this specific sector, we provide antifoam solutions based on food-grade silicone, natural oils, and polymers.
One of the main applications of antifoams in the food industry is vegetable processing. The vegetable processing and treatment chain includes manufacturing processes such as washing, peeling, and blanching vegetables, where foam formation is a very common issue.
Why is foam generated in these processes?
Vegetables release surface-active substances, such as starches or proteins, which accumulate in the system’s recirculation water and generate foam. Common vegetables such as peas, chickpeas, and spinach tend to have a higher propensity to generate foam.
Which is the best antifoam solution to prevent this foam generation?
For this type of application, we recommend the use of the antifoam EMULTROL® DV-15 FG, a food-grade silicone-based antifoam (E-900), with the following key features:
- Maintains good stability and dispersibility.
- Highly effective at low dosages.
- Does not affect the smell, taste, or appearance of vegetables, provided it is used correctly and in the quantities indicated by technical support.
- High persistence, even during agitation and recirculation in the washing process.
- Offers a better cost-performance ratio.
- Features a more cost-effective emulsifying system compared to other food-grade silicone-based antifoam varieties.
As EMULTROL® DV-15 FG is composed of food-grade silicone, it may be used, in accordance with Regulation (EC) No 1333/2008 of the European Parliament and of the Council of 16 December 2008, as a food additive, as a processing aid, or even as a direct or indirect food contact additive, depending on the application and the legislation of the country or community region concerned.
How is it applied during the vegetable washing process?
- It is added at the point of highest foam generation, usually where there is no mixing, aeration, or water inlet.
- Reduces losses due to foam in tanks and conveyors.
- Facilitates the management of recirculated water, streamlining cleaning and maintenance.
- Maintains product quality without altering organoleptic properties when used properly.
What advantages does the EMULTROL® DV-15 FG antifoam provide in vegetable washing?
- Improves process flow and prevents foam overflows, and the resulting potential shutdown of the washing process.
- Reduces losses due to foam in tanks and conveyors.
- Facilitates the handling of recirculated water, speeding up cleaning and maintenance processes.
