Miscella Clarification: How to improve the soybean and seed oil lecithin quality

Wednesday, April 30, 2025
8:55 AM – 9:15 AM PST
Room: A107-109
Abstract:







Vegetable lecithins are by-products of the production of soybean, sunflower and rapeseed oil. As natural emulsifying agents with first-class technological and nutritional-physiological properties, these lecithins are highly valued in the food industry in particular. Today, already more than 800 million people consume products daily which contain lecithin. More and more synthetic emulsifying agents and stabilisers are being replaced by lecithin. Our process know-how ensures high lecithin quality and offers alternative pre-treatment for higher added value in the overall process.


High-quality lecithins are characterized by a clear, bright color. This quality feature is requested especially in the production of foodstuffs, but also in many other applications. That means that solids content is decisive for the quality of your lecithin. But it is not simply getting the solids out of the process that makes for premium lecithin, it is the stage in which you remove them.

The earlier you get them out of your process, the better the quality. For this reason, the ideal solution is to integrate miscella clarification already into your extraction stage.
Only this early separation of solids from the miscella reduces the effects of thermal strain. The more solids you process through the second and third distillation stages the darker the color of your lecithin.

Miscella clarification does not only produce brighter lecithin. On account of the integration in the extraction stage, there are no oil losses and no waste water is produced. Another advantage is that filter aids are not required. It also keeps the distillation equipment clean. Usually, neither a cleaning during the year nor an increase of steam pressure to compensate fouling is necessary. The integration of the clarifier takes up only little space and additional operating staff is not required.
