TONSIL® bleaching earth for refining edible oils
Edible oils - an indispensable food
Edible oils represent an indispensable ingredient in food and food preparation around the world. On a yearly and worldwide basis, around 157 million tons of edible oil are extracted from oil-rich seeds and fruit. These products are abundant in nutrients, have a long storage life, and are suitable for different culinary applications.
Refining process stages
The oil is not merely pressed from the oil-rich material. It undergoes a multistage refining process to remove impurities, dyestuffs, and residues that can degrade the quality of the oil.
Materials based on natural bentonite clay, like Clariant's TONSIL®, play a decisive role in refining edible oils as they possess high absorption capacity. Once TONSIL® particles absorb the impurities and contaminants, they are filtered through by presses.
Finally, the remaining quality-affecting compounds and contaminants are removed from the oil by the process of deodorization. This process stabilizes the shelf life and taste of edible oil.
Die Lösung
Hochaktive Bleicherde auf Basis natürlicher Ressourcen verbessert die Ölqualität erheblich
Tonsil® Bleicherde , die aus dem natürlichen Tonmineral Bentonit gewonnen wird, hat eine reinigende Wirkung. Sie wird durch eine Säureaktivierung von Bentonit gebildet, wodurch seine besondere Schichtstruktur verändert wird: Der Austausch von Ionen gegen Protonen ermöglicht, dass zusätzliches Wasser zwischen die Schichten treten kann und das Mineral aufquillt.
Dabei verfünffacht sich die Oberfläche. Die aktivierte und enorm vergrösserte Oberfläche kann alle unerwünschten Substanzen und Verunreinigungen des Öls aufnehmen.
Innovative solutions to tackle your needs
Clariant can reproduce your edible oil refining process on a laboratory scale and accurately tailor TONSIL® solutions to your needs. At the same time, our tailor-made formulations efficiently tackle the challenges of minimizing the level of 3-MCPD esters and glycidyl esters (GE) in palm oil depending on the actual feedstock.
Our TONSIL® range of bleaching earth or clay is based on over a century of experience in refining edible oils and fats. Today, Clariant remains a truly global player and thought leader for edible oil purification.
