Food Processing Issues

- Hygiene as high TPC

- Corrosion and pitting on contact surfaces

- Chemical safety

- Staining or deposition of chemicals

- Chemical usage levels

- HACCP

- Time consuming

- Cost

- Environmental issues

Sanitization

- Steam

- Hot water

- Chemicals – effective against microbial

o Soluble in water

o Low toxicity

o Not corrosive

o Effective at low concentration

o Unaffected by water condition

o Safe

o Compatible with detergents

o Suitable for many application

o Economical

o Easy to identify

QAC – low toxic and safer

Chlorine releasing compound – rapid action 7 low cost

Amphoterics – low toxic & safer

Peracetic acid – rapid action

Alcohol –

Idophors –

Disinfection: on cleaned surface to reduce spoilage causing organism to safe level.
