Optimise moisture content of petfood and prevent mould growth throughout shelf-life.

Among the most important quality indicators for pet food are stability and freshness during stor­age. And of course, safety is non-negotiable. With all these attributes in mind, it can be a challenge to maximise quality targets such as palatability, production effi­ciency and nutritional value, whilst keeping the product free from moulds. Careful extrusion processing tends to aim for a low final moisture level in the finished kibble. Though this helps to control mould growth, it often affects the cost of ex­trusion efficiency and profitability. Achieving the proper bal­ance of moisture content, throughput and petfood quality can support safety and quality parameters without sacrificing production efficiency.

Fylax Petfood is a synergistic blend of organic acids and surfactants. Organic acids reduce moulds to maintain the nutrient value and prolong the shelf life of raw materials, compound animal feed and petfoods. The surfactants act to optimize the distribution of Fylax Petfood throughout the feed and increase its water binding capacity. This improves both its anti-mould effect as well as feed mill efficiency.

Fylax Petfood contains a patent-pending new technology, called ActiProp®. ActiProp increases the porosity of moulds’ cell walls, while its components exert a destabilising effect on the cell membrane. As this effect supports better accessibility of organic acids, the cell’s internal pH decreases, inhibiting its growth and eventually killing the mould cell.

This mode of action is driven by the synergy of four key components delivered in the most effective quantities:

  1. Propionic acid - A highly effective broad-spectrum organic acid that attacks moulds
  2. A buffering agent - This reduces evaporation and the corrosive nature of the propionic acid, enabling a prolonged effect and safer handling
  3. An emulsifier - This supports better spread and may facilitate the intake of organic acids inside the mould cells
  4. Phytochemicals - These compounds derived from palm splitting have proven high synergy with propionic acid.
