food emulsion is defined as‚ “a colloidal dispersion of two liquids‚ usually oil and water‚ that are immiscible.” (Murano 2003). To better understand what this definition is stating‚ a colloidal dispersion must also be defined. A colloidal dispersion is a dispersion of food colloids‚ a dispersed phase‚ into a continuous phase such as water or oil. Keep in mind‚ however‚ that a colloidal dispersion is not a solution‚ and the two liquids are said to be immiscible‚ meaning unmixable. Food colloids are

5.1 Recommendation References Appendix CHAPTER ONE INTRODUCTION Drying is a thermal process which involves the final removal of volatile constituent from a substance to reduce the content of the residual liquid to an acceptable low value .Drying of a material is often the final step in a series of operation in manufacturing process‚ carried out immediately prio to packaging or dispatch. Excluding the partial drying of a solid by mechanical means (e.g centrifuges)

The solute is the substance that dissolves. The solvent is the substance that does the dissolving. Solutions are homogeneous and do not show the tynall effect. E.g. salt and water. Suspensions They are heterogeneous mixtures of a solid and a liquid in which the solid does not dissolve. Suspensions will settle when left undisturbed. Suspensions will show the tynall effect. E.g. sand and water Colloids They are mixtures with characteristics part way between solution and suspension. Colloids

Strategy We’ll start with Raoult’s Law (eq 5.21 on pg 164) which relates the partial pressure pa of a liquid in a solution to its pure vapour pressure p∗ by its mole fraction in solution χa . a pa = χa p∗ a This allows us to calculate the mole fraction of 2-propanol χp (in the solution with the dissolved unknown) to the solutions vapour pressure pp

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in

Firstly‚ the liquids wet the solid and penetrates the pores of the tablets. Thereafter the tablet breaks into smaller fragments. Disintegrants to be used in plain tablets are classified into: Disintegrants that facilitate water uptake -These disintegrants act by facilitating the transport of liquids into the pores of the tablet may
