THE NEED FOR MOULD INHIBITORS

The presence of mould growth in pet foods and raw materials decreases the nutritional value of the pet food. Toxic secondary metabolites, called mycotoxins, can further be produced by mould, putting animals at risk of mycotoxicosis. Mould growth and the production of  mycotoxins should be prevented at all costs. Although mycotoxins can be treated once formed (by mycotoxin binders) it is preferable to prevent their formation through the inhibition of mould growth.

Grains and pet foods, having a high energy and nitrogen content, are ideal substrate  for mould growth. The additional, inevitable presence of moisture contributes to the proliferation of fungus. The presence of heat and temperature fluctuations also plays a major role.

Temperature fluctuations during storage in bins and bags causes moisture migration. Moisture accumulates near the top and around the sides of the bins/bags, increasing susceptibility to moulds and yeasts.

Signs of mould growth in pet food are the following:

heating in pet foods or grains

a slight “off” odour

darkening of the pet food

ropiness

food refusal by animals.

With the handling of grains during loading and unloading for transportation, the outer layer of the kernel suffers small cracks. These cracks offer easy entry for mould spores into the kernel. Should these grains now be exposed to heat or moisture fluctuations, mould growth will take place.

Bitek’s mould inhibitors protect all pet foods and pet food raw ingredients by the disruption of macromolecular synthesis in moulds and yeasts. This is achieved through the intracellular accumulation of anions. The ability of moulds and yeasts to multiply is also affected by this anion accumulation.

Initial action utilises primary volatile components resulting in high anti-fungal and anti-yeast activity. Secondary monomeric volatiles are responsible for long term protection, as these are released over time.

MOULD INHIBITORS

The key active ingredient in all Bitek mould inhibitors is the salts of propionic acid together with formic, sorbic and propionic acids. Bitek's mould inhibitors are:

Heat stable - 95% retention of propionate through the extrusion process.

Immediate and rapid kill off of spores and vegetative cells.

Long term protection.

Our range of mould inhibitors are used to treat finished pet food and raw materials ranging from whole grain storage to extending the shelf life of hominy chop.
