Why? they both change color Experiment 2: Starch Test Fill in the table below with the results from the starch test experiment. Results Starch Test Solution Initial Color Color with Iodine Solution starch solution clear purple water clear yellow-green Iodine solution is added to a chocolate chip cookie solution. The color changes to purple. Based on this result, what biological molecules are present in the chocolate chip cookie solution?

Experiment Chromatography Of Food Dyes Abstract This experiment is to determine the presence of a mixture in a substance. Chromatography is used to separate substance in a mixture or separating components from a mixture. Using chromatography with a solvent we are able to separate the different mixtures found in a substance. Chromatography can tell if a sample is pure or if it is made up of several different substances. Experiment & Observation I gathered together my items; distilled water, salt, ruler, scissors, stapler pencil, tape, 16 toothpicks, Kool-Aid drink mix strawberry and grape, set of McCormick food coloring red, yellow, green and blue, small bag of M&M candy, plastic beaker 50 mL, petri dish 60mm, well-plate 24, FDC blue dye #1 0.5 mL vial, FDC blue dye #2 0.5 mL vial FDC red dye #3 0.5 mL vial, FDC red dye #40 0.5 mL vial, FDC yellow dye #5 0.5 mL vial, FDC yellow dye #6 0.5 mL vial, unknown 0.5 mL vial, 3 filter paper chrom 14x7 cm.
How is it made? Ice cream is a mixture of cream and/or milk, sugar and sometimes eggs that is frozen while being churned to create a frozen product. In commercial ice-cream making, stabilizers, such as plant gums, are usually added and the mixture is pasteurized and homogenized. The mixture may have flavourings added, e.g. vanilla and fruit.
magnets zipper locking plastic bags beakers Petri dishes micro spatulas tongs 13- x 100-mm test tubes; rubber or cork stoppers to fit rings, ring stands, gauzes, burners, ignitors ice paper towels filter paper funnels Using this equipment, devise a procedure for the separation of the four substances. Design experiments, and write procedures for the designs. Ask the instructor to approve each experimental design. Questions Explain why the sodium chloride is contaminated with benzoic acid. Suppose sawdust from wood less dense that water were incorporated into the mixture.
* They are able to work in the presence of chemicals that usually stop enzymes working. 3. Describe how carbohydrase enzymes are used to obtain glucose sugar? Carbohydrases are enzymes that break down starch into sugar syrup. Manufacturers use carbohydrase enzymes, such as amylase, from microorganisms.
“Hey there’s corn in my candy!” corn syrup is a sweet substance made from processed cornstarch. Corn syrup that is made in food and drinks is called “High-Fructose Corn Syrup” (HFCS). It is mostly used in soft drinks, and many foods and baked goods. Most people say sugar is a white powdery substance that we use to make our food sweet, but actually, it is more than that. Sugar is known as sucrose and it comes from two different plant sources.
In this lab I will extract the DNA from a strawberry and an orange for the extraction to analyze its effect. Experimental Design Variables: MV: Fruit in which DNA will be extracted RV: DNA visibility C: Time mashed, amount of detergent added, amount of pineapple juice added, amount of filtrate added in the test tube, amount of ethanol added Materials: Heavy Duty Zip lock Strawberry Orange 60 ml detergent-salt solution 2 ml pineapple juice (natural enzyme) 2 filter (gauze) 2 funnel 2 test tube 2 beakers 2 rubber bands 2 graduated cylinders 2 glass stirring rods Ice cold ethanol Procedure: Place 1 large strawberry into a zip lock bag and crush for about 1-2 minutes Add 30 ml of the soap detergent solution into the bag Crush and mash again until the solution is smooth Add 1 ml of pineapple juice to the bag Mix gently for 1 minute—just get the pineapple juice (containing natural enzymes) evenly distributed. Gently pour the solution through filter (gauze) into a beaker Funnel 6 ml of the filtrate (filtered liquid) in the test tube Obtain 6 ml of ethanol from the teachers lab station Carefully pour the ethanol
ABSTRACT In this study we aim to find out the breaking strength of the two treatments (A and B) and if there is a significant difference on each of the breaking strength. To test the breaking strength of the cassava and corn starch used as biodegradable plastic production have other application. This can be used as a mouse pad that is cheaper and safe to use. The researchers conducted an experiment through the experimental design employed in the study. The researchers used two treatments in conducting an experiment.
The Streptococcus provides the lactic acid to the yogurt, which gives the sour taste. A small amount of yogurt can be used to introduced a new batch of yogurt, since the bacteria reproduce and multiply during fermentation CHEESE There are hundred types of cheese. Cheeses are made from milk, rennet, salt and microbes. The milk is acidified with a microbe and then enzyme rennet, such as acetic acid or vinegar, is added. These ingredients are brought together by coagulations, acidification, syneresis, and ripening.
