Our products

The company specialises in the manufacture of non-distilled fatty acids for feed and technical use. Fatty acids are constituents of vegetable fats. Light vegetable oils and refining waste (soapstock) are used as raw materials. Fatty acids are obtained from fat raw materials by non-reactive splitting or splitting with mineral acids. The technology makes it possible to obtain fatty acids characteristic of a particular oil.

Fatty acids for feed

Vegetable oils and fats are an essential part of the diet of farm animals. Adding fats to compound feed significantly increases its energy value — fats contain 2.3 times more energy than carbohydrates. Fats carry fat-soluble vitamins and improve their absorption, reduce feed dustiness and are a source of essential fatty acids.

REKAST products are modern, energy-efficient, standardised fat blends based on vegetable oils and fatty acids. All products are manufactured in accordance with applicable EU law and tested for safety parameters according to GMP+.
