M5:T5: Industrial controls

• list the different controls

  1. preventative controls
  2. storage conditions
• list the type of preventative measures

  1. quality systems: planning an documentation and training
  2. monitoring programs: testing regimes and environmental monitoring
• explore preservatives

  • prevent contaminaition
  • 3,000 compounds are used as additives
  • hydroxygbenzoate and position sorbate
  • extends shelf life
• why are nitrate controversial as preservatives

  • harmful to human body
• explore natural preservation

  • many foods are preserved, produced and enhances by actions of microbes
  • fermentation in food industry
  • bacterian production or decrease pH
• compare storage conditions 


  cold: slows microbes growth rate and delay spoilage and psychrotolerant microbes which are a problem

  hot: moisture content is critical for met process

  • lyophilisation which is freeze during is the removal of water under a vacuum
