Physical Chemistry

Physico-chemical analisys are intended to determinate, quantify or qualify the specific components of food, e.g. to determine the centesimal composition and provide information on the chemical and/or physical-chemical composition of the product.

It may be used for the following purposes:

 

  • Nutritional assessment of a product
  • Quality control of food
  • Shelf life control
  • Development of new products
  • Monitoring required by legislation
