Unit 8 - Lesson 8D

What does Willy Wonka's magical chewing gum have in

common with types of nano-food in development?

• They both contain an exciting mix of tastes.

• Both are appealing to young children.

• They both allow the consumer to choose the flavours .

• They're both made in a factory.

Which elements of 'programmable food' would consumers be able to determine by zapping it?

• colour, consistency and nutritional value

• temperature, colour and taste

• taste, nutritional value and colour

• texture, taste and colour

Unlike ordinary packaging, 'smart' packaging

• keeps food fresh permanently.

• prevents any oxygen from reaching the food.

• has yet to arrive on supermarket shelves

• can monitor the condition of the food it contains.

Technology developed to keep cooking oil fresh could

help the world's poorest people by

• increasing their consumption of nutrients.

• preventing fish from going off too quickly.

• alerting them when water supplies become

  contaminated.

• enabling them to purify water more easily.

At its most advanced, nano-technology might enable

consumers to

• experience previously undreamed-of combinations of

  tastes.

• make any food they can think of without the need for

  conventional ingredients.

• have a much higher level of protein in their diet.

• avoid foods they dislike altogether.

In the opinion of the scientist David Bennett, how will the

public react to nano-food?

• They'll give it a cautious welcome.

• They'll be too concerned about the dangers to welcome it.

• They'll eventually be won over by all the potential

  benefits.

• They'll want to decide whether the potential benefits

  outweigh the dangers.

How is the size of nano-particles relevant to their

potential dangers?

• Most substances are toxic at nano-scales.

• They are too small for scientists to track their position.

• Once they're inside the body, they behave like viruses.

• Their microscopic size allows them to pass through the

  body's usual defences.
