Identify the production systems used in food manufacture - ✔✔ Manual production systems
Automated production system
Computerised production
... [Show More] systems
Descibe the features of manual production systems - ✔✔ Manual production systems
- They physical handle material
- Suitable for small scale production
- Some mechanical equipment may be used
- More cost effective to use labour rather than invest in large expensive equipment
Describe the features of automated production systems - ✔✔ Automated production system
-Specifically designed machines carry out repetitive actions
- Production flows automatically from one process to the next
-Product standardised to ensure , manual handling is minimal and the cost of labour reduced
Production equipment should be: - ✔✔ Smooth
Impervious to water
Inert
Durable
Motionless
Accessible
What are the raw materials used in the food industry? - ✔✔ A raw material is any product that is used in the manufacture of another processed food. They are used in food processing (manufacturing process, food additives and packaging)
Explain sous vide process, including the packaging process used - ✔✔ Sous-vide is a used to extend the shelf-life of foods by using minimal heat treatment. Foods are cooked in sealed air-evacuated, heat stable pouches to preserve flavout and appearance and then blast-chilled to 3-C.
What is the function of Acids/acidity regulators as a food additive? - ✔✔ s help to maintain a constant acid level in food. This is important for taste as well as to influence how other substances in the food function. For example an acidied food can retard the growth of some micro-organisms
What is the function of the food additive Anti-caking agents? - ✔✔ s reduce the tendency of indivisual food particles to adhere and improve flow characteristics. For example seasoning with an added anti-caking agent flows freely and doesn't clump together
What is the function of the food additive Anti-oxidants? - ✔✔ retard of prevent oxidative deterioration of food. For example in fats and oils, rancid flavours can develop when they are exposed to oxygen. Anti-oxidants prevent this from happening
What is the function of Bulking agents as a food additive? - ✔✔ contribute to the volume of the food, without contributing significant to its available energy. For example sugar often contributes to the volume of lollies while some low joule food need bulking agents added to them to replace the bulk normally provided by sugar
What is the function of Colourings as a food additive? - ✔✔ add or restore colour to food e.g.icing mixture is coloured to make it more attractive on cakes
What food additive facilitate or maintain oil and water from separating into layers e.g. emulsifiers may be used in margarine to prevent oil forming a layer on top. - ✔✔ Emilsifiers
Which food additive maintains the uniform dispersion of substances in solid and semi-solid foods - ✔✔ Firming agents/stabilisers
What is the function of food enhancers as a food additive? - ✔✔ enhance the existing taste and/or odour of a food
What food additive mainins the uniform disperation of gases in aerated foods? - ✔✔ Foaming agents
What food additive modify the texture of the food through gel formation? - ✔✔ Gelling agents
What food additive impart a coating to the external surface of the food e.g. a wax coating in fruit to improve its appearance - ✔✔ Glazing agents
What food additive reduces moisture loss in foods. E.g. glycerine may be added to icing to prevent it from drying out? - ✔✔ Humectants [Show Less]
