Smart foods

• What are smart foods?Smart foods are those that
  have been developed through the invention of new
  or improved processes, for example, as a result
  of man-made materials/ingredients or human
  intervention in other words, not naturally
  occurring changes.
• Smart foods may
• have a function, other than that of providing
  energy and
• nutrients
• perform a particular function never achieved by
• conventional foods
• have been developed for specialised
  applications, but some
• eventually become available for general use.

Smart foods include 1. Modified starches. 2.
Functional foods, e.g. cholesterol lowering
spreads, probiotic yogurts, fortified
eggs. 3. Meat analogues, e.g. textured vegetable
protein (TVP), myco- protein and tofu. 4.
Encapsulation technology, e.g. encapsulated
flavours in confectionery 5. Modern
biotechnology, e.g. soy bean, tomato plant,
modified enzymes, e.g. chymosin.

Meat Analogues
TVP is used in vegetarian shepherds pie to
provide the main source of protein.

Myco-protein is used in fillets to provide a
chicken like texture.
Tofu absorbs flavours, so is used as a meat
alternative in stir-fries.
