INTRODUCTION TO MICROENCAPSULATION AND MICROENCAPSULATED PRODUCTS

introMicro-encapsulation is a process in which tiny particles or droplets are surrounded by a coating to give small capsules of many useful properties. In general, it is used to incorporate food ingredients, enzymes, cells or other materials on a micro metric scale. Microencapsulation can also be used to enclose solids, liquids, or gases inside a micrometric wall made of hard or soft soluble film, in order to reduce dosing frequency and prevent the degradation of pharmaceuticals .In a relatively simple form, amicrocapsule is a small sphere with a uniform wall around it. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane. Food manufacturer’s are using microencapsulation to get essential ingredients to exact places in the body where they are required.

Food products that have had microencapsulated ingredients incorporated into them include:

  • cheese
  • ice-cream
  • yoghurt
  • margarine
  • spreads
  • baked products
  • health drinks
  • breakfast cereals
  • mayonnaise
