Fortifiers
These are substances with no nutrient
value but are added to improve the
appearance, flavour, texture and/or
storage properties of the food.
Additives
These are substances added to increase
the nutrient value of the food.
Residues
These substances are left over chemicals
in the food, that were originally used to
increase productivity. E.g. pesticides,
hormones, herbicides.

Residues are the remains of chemicals used to increase food
production. For example, if a heard of cows are injected with
chemicals to keep them healthy or prevent disease, some of
those chemicals may remain in the meat of the cow when it is
slaughtered for food. Meaning we consume those chemicals
when we consume the meat.
Pesticides and herbicides are toxic chemicals
sprayed onto plants to kill insects and weeds. The
crops can tolerate these chemicals and can absorb
them. This means that when we consume the
crops, we are also consuming the toxic chemicals.
Some animals are fed hormones, like oestrogen, to
increase their growth rate. Oestrogen is a female
hormone, meaning that when it is consumed by
men it can cause them to develop female
characteristics.
The use of pesticides has
increased my yearly crop
yield by 50%. I think I may
start using herbicides as
well to help increase my
yield.
Grade C: Explain the term “residue”.
Grade B: Give examples of two residues left over in
food and explain how they get there.
Grade A: Create a counter argument, around a
paragraph long, against the use of herbicides.
