What is a raw material? - ✔✔Any product that is used in the manufacture of another processed good.
What are some examples of raw materials? - ✔✔Fruit and veggies.
Steam and water.
Emulsifiers, starches, colours and flavours.
Cans, bottles and fibreboard containers.
Suppliers must ensure that raw materials are...: - ✔✔-free of contaminants.
-meet the criteria for the specific characteristics required by the manufacturer (size, colour, moisture
level).
Why must raw materials meet strict guidelines? - ✔✔Because just one delivery of contaminated
material can mean the spoilage or rejection of a complete production run.
Tests conducted are referred to as 'Quality Control'.
What are some raw material specifications? - ✔✔1. Description of raw material.
2. Sampling method for material.
3. Test each specific characteristic needed.
4. Action to be taken when tests have produced a result.
What are food additives? - ✔✔Substances added to food that are not normally consumed on their own.
What is the function of mineral salts?
What foods are the commonly added to? - ✔✔To improve texture and mouth feel of processed foods.
Also an anti-caking agent.
E.g. Beer, confectionary, ice cream, baked goods, cheese.
, What is the function of maize thickener? - ✔✔Used to make a food more viscous and ensure a
consistent texture.
What is the function of antioxidants?
What foods are they commonly added to? - ✔✔Prolong the shelf life of a product by preventing
oxidation.
Commonly added to fats and oils as these are prone to oxidation. E.g. Vegetable oil, animal fat, salad
dressing, fish.
What is the function of humectants? - ✔✔Absorb moisture from the atmosphere so that the food does
not dry out.
Salt and sugar are humectants, sorbitol.
What is the function of emulsifiers? - ✔✔Allow oil and water to mix in production without separating.
E.g. Lecithin stabilise oil and vinegar in mayo.
What are some examples of preservatives and what foods are they found in? - ✔✔Natural
preservatives: salt, sugar, alcohol, vinegar e.g. Jams and juices.
Chemical preservatives:
Benzoates (sauces, jams, beer).
Nitrates (processed meats e.g. Bacon).
Sulphites (dried products, e.g. Dried fruit, garlic, potatoes and alcohol).
Sorbates (Dairy, baked goods, alcohol, dried meats).
What is the function of food acids? - ✔✔Maintain a constant level of acidity; produce a sharp taste.
What is the function of vegetable gums?
What are some examples? - ✔✔Impart consistency and texture.
E.g. Agar (dairy products)
Cellulose gum (prevents ice-crystallisation in ice cream).
