Eggs are a key ingredient used to make a foam. Investigate the functional and chemical properties of eggs and other ingredients when making meringue. Chemical and Functional properties of eggs: Background information Eggs give a smoother texture to microwaveable dishes‚ frozen dishes are better to freeze. The yolk and the egg white cam be used in many different ways for different products of food. Eggs contain a lot of protein and a balance of other nutrition. Some producers require fresh eggs to

Lab Report Experiment #3 Chemical Aspects of Life The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for

This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds’ (Wikipedia‚ 2011). This method is similar to thin layer chromatography‚ but the compounds in the mixture are collected separately. Green dye is used in this experiment that consists of blue and yellow constituents

Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

INTRODUCTION Sugar is one of the main food items consumed in Sri Lanka. The annual per capita consumption of sugar in Sri Lanka is around 30 kg and the total annual requirement of sugar in the country is around 550‚000t. But‚ only about 50‚000 t are produced locally. In a year only 38‚000 t were produced. The balance requirement has to be imported. The total annual expenditure on sugar imports is around Rs. 20 billion. Sugar cane (Saccharum officinarum) is the only crop cultivated in Sri Lanka

Mr. Brown all your tests look ok. Your triglycerides are at 145‚ cholesterol 210‚ hdl 33‚ and ldl 160. Triglycerides are chemical compounds digested by the body to provide it with the energy for metabolism. Triglycerides are the most common form of fat in the body. They are the main ingredient in vegetable oils and animal fats. Cholesterol is a soft‚ waxy substance found in all of your body’s cells. Your body needs cholesterol in order to work properly.

The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected
