Organic and inorganic acids used by feed industry.

Acids are usually used in feed industry as antibacterial, anti-mould or acidifying factors.

• Phosphoric acid: inorganic, liquid in natural, no sour smell, corrosive
• Acetic acid: organic, liquid in natural, sour smell, corrosive
• Formic acid: organic, liquid in natural, sour smell, corrosive
• Propionic acid: organic, liquid in natural, sour smell, corrosive
• Lactic acid: organic, liquid in natural, nice smell, corrosive
• Citric acid: organic, crystalic or powdered in natural, nonintensive smell, less corrosive

Technical notice:
Usually organic and inorganic acids are not used by feed industry as pure forms because they are corrosive. To eliminate the problem there are available liquid or solid-dry forms properly buffered (buffered saline) to weaken corrosive property.

Mentioned recombined forms are more expensive then pure acids.
There are acid additives less expensive but more corrosive.

It's recommended to use products from checked, trustworthy firms who offer good quality, non-corrosive acid additives.
