Revalet is a broad range of products based on synergistic blends of organic acids and surfactants formulated to reduce yeasts, moulds and Enterobacteria in by-products. The objective is to extend the shelf life of co-products and preserve the nutritional value, creating a high quality raw material which can be used for animal feed.

Product application

Revalet is Selko’s feed additive solution which can be applied in-line when by-products are leaving the production process, before entering the storage tanks.
