Definition food standards agency
government body responsible for food safety and hygiene. It works to ensure that food is safe to eat, what it says it is, and produced ethically.Enforces:Food safety act 1990Hygiene regulations Allergen labelling
Environmental Health Officer EHO definition
Responsible for enforcing food safety laws and ensuring hygiene standards in food businesses. They work for local authorities and inspect food establishments to protect public health. They have the legal authority to inspect food businesses without warning, require businesses to fix hygiene issues and prosecute businesses that repeatedly fail to meet food laws.
Due diligence
Being able to process that reasonable action has been taken to avoid a health risk.
Critical control points
Stages in food production operation where food safety could go wrong, and where measures can be put in place to prevent this.
Glycemic index (GI)
a system for rating foods according to how rapidly and by how much they individually raise the blood glucose level in a person. Low GI food include fruit, vegetables and whole grain foods. High GI food include sugary foods, sugary drinks and potatoes.
Why has the glycemic index been criticised?
• As values for specific foods can vary considerably •GI of some foods are affected by factors like fruit ripeness and how it’s prepared or cooked• GI value of specific foods varies up to 50% depending on the person
Basal metabolic rate (BMR)
The minimum amount of energy needed by the body to stay alive and function whilst the body is warm and at rest.
Metabolic rate
the amount of chemical energy released in the body to carry out biochemical reactions in a given amount of time
Why does BMR vary in different people?
BMR accounts for approximately 79% of the energy used by the body, but various depending on factors:•Age- BMR decreases with increasing age after adulthood is reached •Body size- as body grows so does BMR•Pregnancy- Increases as to accommodate growth of newborn
Nutrient density
its the measure of the number and quantity of different nutrients in food. an example includes white sugar which only contains one nutrient simple carbohydrates meaning it has a low nutrient density. spinach has a high nutrient density as it contains many different nutrients like protein and many minerals and vitamins.
Biological value
how much of a nutrient in a food is used by the body, after the nutrient has been digested and absorbed from the small intestine.
High risk foods
foods that favour the growth and multiplication of micro-organisms. Include meat, poultry and seafood.
Allergens
Natural substances in particular foods that cause allergic reactions in people e.g nuts, shellfish and soya.
Anaphylaxis
A severe and life threatening allergic reaction to an allergen.
Food allergy
A reaction to specified foods, which cause severe and potentially life threatening symptoms, usually very quickly after consuming food.
Food intolerance/ sensitivity
A long term condition where the consumption of certain foods causes someone to feel unwell and have a range of symptoms, usually not life threatening
Histamine
A chemical that is released in the body in response to an allergen, and cause a range of symptoms such as the swelling of mouth, tongue and throat.
Low risk foods
foods that do not provide all the conditions that micro-organisms need to grow and multiply. Include foods with little moisture like biscuits, crackers and cereals. And with high salt sugar and acid concentrations like salted fish, jam and syrup.
Pathogenic bacteria
Microorganisms that cause food poisoning
Bacteria
Single celled organisms that can only be viewed in detail under a powerful microscope.
Spore
Tiny reproductive unit produced by moulds to allow them to spread and multiply
Food spoilage
When food has become unpalatable, unfit and unsafe to eat
Yeast
Fungi that are single celled. They need optimal conditions to grow e.g pH 4-4.5 and a supply of moisture
Mould
They are fungi and grow on the surface of foods and are visible without a microscope, they need optimum conditions to grow and multiply e.g a supply of moisture and a supple of energy and nutrients
