Food Chemistry Assignment 1 1. Why would you use D-glucono-δ-lactone in a refrigerated pizza crust? Which additional ingredient do you need for D-glucono-δ-lactone to work and why? (5 points) D-glucono-δ-lactone is a leavening agent so is added to pizza crust to cause expansion of the dough. When water is added to the dough mixture containing D-glucono-δ-lactone and sodium bicarbonate, they dissolve.
How does the amount of baking soda mixed with vinegar affect the volume of gas produced? The rate of reaction is the increase or decrease time taken at which the products are formed or concentration increase or decrease between a reaction of two or more substances. In the reaction, new bonds are formed whilst others have been broken. When a solute acts on a solvent a chemical reaction takes place. Here we will be using baking soda and vinegar which are our two components which will cause a chemical reaction.
The dependent variable is the product of the chemical reaction and the formation of gas filling up the bottle eventually causing an explosion. The independent variable is the baking soda and vinegar react. My control conditions are a water bottle that is about 8 inches in height and about 3 inches in width and I will use about 6 grams of baking soda and ½ a cup of vinegar. I will put protective glasses to avoid damage to my eyes and I will first pour the vinegar
Once your oil reaches 350° F, it's fry time! Using a metal spatula, lower each donut into the hot oil. The donuts will sink to the bottom at first, then pop up to the top. Cook them for 60 seconds then flip and cook the other side for 60 seconds or until the donuts are golden brown and then transfer to a wire
Have you ever made pancakes? A better question is, have you ever made pancake art? Now for those of you who don't know, pancake art is when you draw on a skillet/pan with some pancake mix and voila you have just created pancake art, so i thought i would show you step by step how you can achieve these glorious pancakes. Designing pancake art may seem very easy but let me tell you from experience, its easier said than done. Before you get started you can think up an idea of what to draw or wing it!
Allow the both sides to turn crispy and browned before removing from the pan. Repeat this process for the remaining slices of bread and batter. Brush the pan with butter as needed. Note: Do not allow the bread to stay longer in the egg mixture. It might take longer time to cook since it will absorb more of the mixture and becomes excessively soaked.
o Unknown sample (18) is yellow in color o First time attempting to dissolve, the solution looked like it fully dissolved but once it began to cool, it began to crystallize again boiled again o After adding the charcoal, solution started to turn a mint green color and after heating again the solution became very clear and light green color o Accidently got charcoal in flask when it was being filtered so we filtered it twice o 1st filtration had too much water, crystals did not form when placing flask in ice bath Discussion and Results: When determining the melting point of Benzoic Acid, we observed that the solid began melting at a temperature of 122.6 ºC. Due to this temperature reading we came the conclusion that apparatus #4 has a calibration error of approximately ±0.2 ºC. This error could be due to small impurity of the solid as well as technical malfunctions with the
The water vapour condenses on the cold surface of the jar to form water. 3.6.3 Why do the candles die out at different times? Figure 7: Candles being smothered in the Candles in a Jar experiment Carbon dioxide and other gases are warm gases which expand. As the warm gases expand the remaining oxygen is pushed down to the bottom of the jar (more space for warm air). There are also now more particles of carbon dioxide and water vapour than oxygen.
3. Salt the boiling water generously. By adding salt into the cooking water, it helps the potatoes cook faster and break apart better, which will result in a fluffier and creamier result. 4. In a microwave oven or a saucepan, heat the butter and milk together up until the butter melts and the mixture
Yeast and sodium bicarbonate (baking soda) are examples of leavening agents. They produce bubbles that get caught in the gluten matrix while the cake bakes. So, similar to the inflation of a fancy air mattress, the air fills the first section quickly. When that section is full, the air continues on to fill the next section. This process continues until the mattress is full.
These ingredients chemically changed out mixture into cupcakes. The powder makes bubbles that occurs immediately after adding liquid-based ingredients. While in the oven, it produces a chemical reaction that also creates bubbles to make the mixture rise. It changes the cupcakes identity and the form because the baking powder produces a carbon dioxide gas. The powder is broken
The vanilla is used for good flavoring while the flour is used to make the dough firm. Milk adds flavor and helps balance the doughs texture wikipedia-the free encyclopedia. Salt is added flavor also. Eggs add protein and oil helps not stick the waffle to the iron or pan. Some good waffle topping are butter, berries, caramel, chocolate and jelly.
Melt a slice of butter on the griddle. Once the griddle is hot, add 1/4 cup of batter for each pancake. Cook until golden brown. Flip and cook the other side. Sourdough Biscuits Ingredients 1/2 cup cold butter, cut into small chunks 2 1/2 cups all-purpose flour 1/2 cup sourdough starter 1 tablespoon sugar 1 cup milk 3/4 teaspoon salt 1 teaspoon baking powder 1/2 teaspoon baking soda Directions Cut the butter pieces into the flour until it is in tiny pieces.
The base is a powder that will react to the acid. The base is the baking soda, a main ingredient in this experiment. The baking soda has a ph level of 9. Since the baking soda has such a high ph level it has a strong acid base.This research helps answer the question by knowing how the base will react to the different acids. The final topic, also in the experiment, is the importance of the materials.
