Physical Conditioning Agents Flashcards
List the five types of physical conditioning agents
Humectants Emulsifiers Anti-caking agents (polyphosphates) Setting agents Stabilisers
What is the mnemonic to help you remember the different types of physical agents?
HEAPS H = Humectants E = Emulsifiers A = Anti-caking agents (polyphosphates) P = Pectin - Setting agents S = Stabilisers
What is the function of humectants?
They prevent food from losing moisture, drying out and hardening
Give an example of a humectant
Sorbitol and mannitol
What is the origin of sorbitol and mannitol?
Lichens
Give a use of sorbitol and mannitol as a humectant
Marzipan
Cakes
What is the function of emulsifiers?
They combine two immiscible liquids and prevent them from separating
Give two examples of emulsifiers
Lecithin
Alginates
What is the origin of lecithin?
Egg yolks
What is the origin of alginates?
Seaweed
Give a use of lecithin or alginates as emulsifiers
Mayonnaise
Dairy spreads
What are anti-caking agents also called?
Polyphosphates
What is the function of polyphosphates?
They prevent lumping (anti-caking) in a dried food
Give an example of a anti-caking agent
Magnesium carbonate
What is the origin of magnesium carbonate?
Laboratory-produced chemical
Give a use of magnesium carbonate as an anti-caking agents
Cake mixes
Chocolate milk powder
What is the function of setting agents?
Act as a setting agent for foods such as jams and jellies
Give an example of a setting agent
Pectin
What is the origin of pectin?
Ripe fruit
Give a use of pectin as a setting agent
Jams
Marmalade
What is the function of stabilisers?
They prevent emulsions from separating by making the emulsion more stable and maintaining the consistency of the food
Give an example of a stabiliser
Carrageenan
Guar gum
What is the origin of Carrageenan?
Seaweed moss
What is the origin of Guar gum?
Guar plants
Give a use of carrageenan or guar gum
