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

7. Residues 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.

8. Pesticides and Herbicides 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.

9. Hormones 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.

10. 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. 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. Learning Activity Connectives Activity
