TA: Gia Hoang Lab 1: Effect of pH on a Food Preservative 9-1-2011 Purpose The purpose of this lab was to determine if a new substance forms when sodium benzoate is placed in a simulated stomach acid. Theory Benzoic acid can be found in a wide variety of plants. It is used as a natural preservative in many foods. Sodium benzoate‚ the salt of benzoic acid‚ has become a more popular choice as a food preservative because it is more soluble in water than benzoic acid. Many food items found today

Lab: Energy Stored in Food Background Questions (5 points each = 10 points): 1. What happens to the molecules of the food that we eat during digestion? 2. What type of metabolism is this? Background information: In this lab we will attempt to set a variety of different types of food on fire and capture the heat energy that is given off. The heat energy from the burning comes form the energy stored in the chemical bonds of the food. The more energy in the bonds‚ the more heat the food will

Fermented foods are made by the partial oxidation of sugars‚ or sometimes other organic molecules‚ in a food product. The difference between this and the normal cellular respiration is that the electron donor from the electron transport chain is an organic compound rather than oxygen. One challenge for producing fermented foods is the pH levels of the food. Bacteria have different optimal pH levels. Therefore‚ as pH changes due to fermentation different bacteria will begin to ferment the food. For example

Am I obese? That’s the first question that you should ask yourself when it comes to the issue of posting calorie counts in New York restaurants. This issue should not be a debate since it is clear that people need be informed about what they are consuming. Having calorie counts in NY restaurants will allow people to make a decision about how many calories they want to consume. The United States has become one of the top countries in the world with an obesity problem. That is because now a day’s

Food Test 1: Test for Glucose – with Benedicts solution Benedicts solution is used to test for simple sugars‚ such as glucose. It is a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a

Lab Two; Chromatography of Food Dyes Jan Konig 28.04.2013 11:00am Chemistry 121‚ section DE Abstract: The second lab deals with the chromatography of food dyes which means you figure out what kind of compounds are used in a product like food color etc. by comparing the result to FD&C Food Dyes. You use six different food dyes‚ four food colors out of the store‚ two different Kool Aid powder and four different colors of candy like M&Ms you use for the chromatograph. At the end you try

Fuels Investigation Aim: To find out which fuel gives out the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific

based on tabloid content” 1. Introduction News has always been a matter of commerce‚ and it has always entertained as well as informed (Barkin 2003‚ p.64). News Ltd‚ undeniably‚ has focused on tabloid content in order to derive an enormous benefit from it. To rise fame‚ broadly speaking‚ News Ltd has exploited the interest of the target audiences‚ crucially by appealing to their human side. This is to say that the success of New Corporations is mainly contributed by tabloid contents. 2. What is tabloid
