Jellies are made from the strained fruit juice, and jams […]
Objectives By the end of this lab, students should be able to describe the process for making mayonnaise and explain the function of emulsifiers and how they work Background Some liquids cannot dissolve in each other. When combined they tend to separate. We call these liquids immiscible, for example oil and water. Being immiscible makes it difficult to prepare […]

Objective: To understand and appreciate the scientific principles involved in making ice-cream Background Ice-cream is a foam. A foam is a dispersion of gas bubbles in a liquid. Some ice-creams may have more air by volume compared to actual solids. The amount of air present in ice-cream is referred to as its overrun. Apart from […]
Objective: To evaluate foods based on their sensory attributes Background: We experience food using our sense of sight, touch, hearing, smell and taste. While there are many instruments that can help us evaluate and estimate these sensations, nothing beats tasting and experiencing the food ourselves. We do this through a systematic (orderly) process called […]
