Modified Allergens

Processed Food

Food Processing can affect the structural and allergenic properties of foods.

Commercial food processing methods include:

preparation, mechanical processes, separation, isolation and purification, thermal processing, biochemical processing, genetic engineering, irradiation, synthetic vitamin fortification and the addition of natural and artificial colors, flavors and preservatives.

Thermal Processing

  • High levels of heat can cause a disorganization within the structure and lead to denaturation of the proteins
  • Once denatured, a protein loses most of its biological activity
  • Chemical modifications of the protein may also occur at high temperatures

Dairy Processing

Homogenization

Heat-Altered Cryoglobulin

Cryoglobulin Destroyed Fat Globule Clusters

Homogenized Milk Fat

Modified Milk Fat

Recombined Membrane

Milk Plasma

Amphiphilic Molecules

Peanuts

  • Multiple studies have also concluded that the thermal processing of peanuts enhances the allergenicity
  • Allergies to peanuts in China are virtually nonexistent as cooking methods lower temperatures with boiling or frying in oil as opposed to roasting

Pesticides on Food

  • Sales for pesticides are approximately $8.8 billion per year
  • Long-term effects of low level pesticide exposure are currently unknown
  • Pesticide use has increased 50 fold over the last 60 years
  • The worldwide environmental cost from pesticide use is $100 billion per year
