Technology Used To Develop New Products

Question 1

Membrane technology

Answer 1

Food in fluid form is passed through a series of semi permeable membrane is similar to a superfine sieve. This results in a filtered fluid.

Examples include fruit juice, low-fat and products like milk, maple syrup

Question 2

Ultrafiltration.

Answer 2

A process in which a liquid is passed over membranes, which have minute pause to prevent macronutrients such as proteins passing through

Examples include milk, apple juice

Question 3

High pressure processing

Answer 3

A technological process that uses high pressure to destroy micro organisms and enzymes whilst retaining food quality as opposed to heat. Products are placed in a high-pressure chamber that is then filled with water to surround the products. A pump is used to increase the pressure of the water and this pressure is transmitted through the package
into the food its self for 2 to 3 minutes

Examples include apple sauce, fruit purée, guacamole

Question 4

Microencapsulation

Answer 4

Small particles of a functional ingredient are contained and entrapped in a fine film of food grade material forming a minute capsule for the inclusion in food

Examples milk with iron, jellybeans, muesli bars, chewing gum

Question 5

Nanotechnology

Answer 5

Manipulation of matter at the molecular scale to create material with new properties. Nanoscale food components added.

Examples include mayonnaise, table salt, low-fat products
