Emulsifiers What does an emulsifier do? Emulsions in food are mixtures of oil and water. These normally do not mix and will separate if left without an emulsifier. Emulsifiers are among the most frequently used types of food additives. They are used for many reasons. Emulsifiers can help to make a food appealing. The example of the mayonnaise without the emulsifier shows how unappealing it would be if the oil and water separated before it was used. Emulsifiers have a big effect on the structure and

less water it will be able to accumulate. Stomatal pores are formed between pairs of specialised guard cells. The wall adjacent to the stomata is thicker than the other walls. When a guard cell swells or shrinks due to the gain or loss of water‚ the thickened wall is the only one to maintain its form. Consequently when the guard cells shrink‚ they shift towards each other‚ closing the stomata. Water enters the guard cells by osmosis. The amount and direction of movement of water is influenced

Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is
