Nutrients In Food Essay

This experiment has to do with foods and their nutrients. We are finding out howmuch nutrients these 6 specific foods have and don’t have: cheese, hotdogs, eggyolk, egg white and potato. We are testing them for starch, sugar, fat andprotein. For my hypothesis I will start with starch. I think that cheese wouldnot have that much starch in it for the reason of this cheese is a dairy it ismade out of milk.

Hotdog’s don’t have starch because it is a meat and meat doesnot have starch in it. My next food is egg yolk. Egg yolk is also a dairy sojust like cheese it is made out of milk also so egg yolk does not have starcheither. Egg white is a dairy too so it too has no starch. The only food that hasstarch in it is potato.

The reason for this is because it is a acid and it growsin the ground. Next is sugar. I would have to say that I think sugar would be incheese, hotdogs, egg yolk and egg white. But I don’t think it would be in potatoagain because they are grown in the ground. My next hypothesis is on fats.

Ithink hotdogs and cheese have fats in them but I think egg white and egg yolkand potato’s don’t have fats. Next is protein’s. Proteins are very common infoods so I think all of the foods we will test has proteins. MATERIAL’S Safetygoggles Hotdogs Cheese Egg yolk Egg white Potato Benedict’s solution hot platelarge beaker 5 test tubes test tube holder test tube rack crucible Lugol’siodine paper bag Biuret reagent EXPERIMENT: We started with testing starch. Wetook a test tube and put one piece of hotdog in it.

I put in drop of Lugol’siodine in it and waited for it to change colors. The drop will turn black ifstarch is present. The drop showed that the hotdog has no starch in it. Next wetook a piece of cheese. We put one drop of iodine in it and it showed thatcheese also does not have starch in it. After that we took a piece of egg yolkand put it in a test tube and put one drop of iodine as we did with the otherfoods.

That showed us that egg yolk does not have starch in it either. Next wetested for egg white. We again put one drop of iodine the test tube. That showedus that egg white does not have starch in it either so every food we have testedso far has not had starch in it. We had one more food to test and that waspotato. We put in drop of iodine in it and it showed that the potato has starchin it.

Next we tested for fats. We took a brown paper towel and placed a pieceof hotdog and rubbed them together. Then we held the paper towel up to thelight. It showed that hotdogs do have fat in them.

Next we took a piece of eggyolk and rubbed it to the paper towel. The paper towel showed that egg yolk doeshave fats in it. After that we tested cheese . We rubbed it on the paper toweland it showed that cheese does not have fat in it. After we tested for cheese wetook a piece of egg white and again rubbed it to the paper towel and that showedthat egg white does have fats in it.

The last thing we tested is potato. Werubbed it to a paper towel and that showed that potato does have fat in it. After we tested for fats we tested for sugar. We took a test tube and put in apiece of hotdog in it. Next we put 10 drops of Benedict’s solution in it.

Afterthat we put it in boiling water for 2 minutes. After 2 minutes the solutionshowed that hotdogs do have sugar in it. After we tested hotdogs we took a pieceof cheese and put 10 drops Benedict’s solution in it and boiled it for 2minutes. The solution showed that cheese has sugar in it.

Next we tested eggwhite and again put the same solution in it and boiled it for 2 minutes and thatshowed that egg white does not have sugar in it. Next we did the same thing foregg yolk. The solution showed that egg yolk also does not have sugar in it. Nextwe tested for potato.

We again used Benedict’s solution and boiled it for 2minutes and the solution showed that potato does have sugar in it. The lastthing we tested for was proteins. For testing proteins we put a piece of hotdogin a test tube and put 2 drops of Biuret reagent in it. That showed us thathotdogs have proteins in them. The solution turned blue.

Next we tested cheese. We again put Biuret reagent in the test tube and that showed that cheese doesalso have proteins in them. The solution turned purple. After that we tested eggwhite. We did the same thing as the other 2 foods and the solution told us thategg white does have proteins. The solution turned purple also.

Next we testedegg yolk. The solution turned light purple so that would mean it has a littlebit of proteins. The last food we tested was potato we again used Biuret reagentand that showed us that potato’s do have proteins. The solution turned purple. CONCLUSION: After we did the experiment we made a graph telling all the results. For my hypothesis I got have of it right.

For starches the experiment showedthat cheese, hotdogs, egg yolk and egg white do not have starch in them, as Ipredicted. The only food that had sugar in it is potato. The foods that havesugar in them are hotdogs, egg yolk and potato. Egg white and cheese do not havesugar in them. I didn’t do so hot on that hypothesis. I thought cheese wouldhave sugar in them, I also thought egg white would but it doesn’t.

Next is fats. Out experiment showed that hotdogs, egg yolk, potato and egg white all have fatin them. The only food that didn’t was cheese. I was right about the hotdoghaving fat in them but I was wrong about cheese, egg yolk , egg white andpotato, they all have fat except for cheese. After fats’s there are protein’s. Ipredicted that all the foods would have protein and I was right.

Our experimentshowed that every food we tested had proteins in them.
