This experiment was preformed in order to figure out which of four different samples of bread containing three different variables grew the most amount of bread over a one-week period.

In kitchens across America, and every other country across the world there is the issue of fast-molding homemade bread. Since these homemade breads have little to no chemical or otherwise preservatives within them, they tend to mold many times faster than average store bought bread. Why cook homemade bread some may ask? Why not walk on over to the nearest super market and buy the cheapest brand? Well many of these overused preservatives have negative health effects on people. People are allergic to a very high percentage of every day preservatives and chemicals used in foods; MSG, Mono Sodium Glutamate is a very common one. (Kerr, Michael, 2012) Ammonium, for example is found in many bread and meat products as a preservative. It is also used in various household cleaners. High amounts of ingested ammonium could be sickening or lethal. ("Questions and Answers about Ammonium Hydroxide Use in Food Production.” 2009.) An alternate preservative commonly used in breads is called Azodicarbonamide. Azodicarbonamide actually can “heighten an allergic reaction to food.” It is also a chemical used to make rubber (Wong,Vanessa, 1 May 2014) and is said to be a cause of asthma according to scientists in the UK.
The objective of this experiment was to measure how natural preservatives (such as sugar, salt and raisins) effect the molding time of homemade bread by using excess amounts of said preservative. It will be compared to the control variable, which is the bread that is left alone with no extra preservatives.
The predicted outcome of this experiment was ...

  • The History and Development of Sliced Bread

    1470 Words  | 3 Pages

    Bread was one of the first foods that was made instead of grown or hunted. Bread dates all the way back to the Neolithic era. By the twentieth century, Americans consumed bread in greater quantities than any other food. Bread has constantly evolved since the Neolithic age, but the manner in which it was served did not change drastically until 1928. Even before the bread-slicing machine, sliced bread was controversial. The act of slicing bread before it was necessary was banned during World War One (Bobrow-Strain). Thus, housewives were forced to cut bread at the table as needed so it would not go stale and be wasted. This prevented the bread from having to be thrown out unnecessarily and new bread, which could have gone to the soldiers, to be bought for the family (“Fascinating Facts”).

    Larger food companies use a lot of things to keep their items on the shelf. Preservatives are commonly found in these unhealthy products. Vileisis states in another chapter “Rise of the Modern Food Sensibility” that throughout history these preservatives have proven to be harmful. In one study she covers, Harvey Wiley, a member of the U.S. Bureau of Chemistry, discovers that in 1904, many preservatives, are harmful to our kidneys and livers (126-28). This can cause many health issues throughout many citizens lifetimes.

  • The Effects of Acids on Molds

    525 Words  | 2 Pages

    There is inadequate research/information on molds and how they are affected by acids. There is not sufficient information on the elimination or prevention of molds on household and grocery items. To test possible solutions, the growth of mold will be examined using different acids to help keep the mold at a low quantity. Two different substances, one with a high acidity and one with a low acidity, will be used along with water as our “mold repellants”. At the conclusion of each trial, each acid’s ability to prevent mold growth will be documented. Conducting this experiment will benefit the scientific world because it researches a problem that has not been thoroughly solved. Perhaps a way to prevent mold from growing can be developed with further study. This experiment will serve as a beginning to what could possibly become a great discovery. The results of this experiment will be beneficial to scientists and could possibly serve as a baseline concept for mold prevention and influence further experimentation.

    Food advertisements, supermarket displays, and restaurant menus increasingly highlight foods, particularly bread, as being gluten-free. Gluten consists of two proteins, gliadin and glutamine, which combine and help produce light and fluffy bread (Lord, 2012). Wheat is bred for its high gluten content which serves efficiently well for all bakers and chefs. Today, gluten is becoming a problem in society since allergic reactions to the protein have increased. Bread is a worldwide staple food and gluten is a predominant aspect within the dough mixture. Gluten free bread is basically fixed as it was thousands of years ago without the fermentation of yeast and the mixture of sourdough.

  • Essay On Food Preservatives

    827 Words  | 2 Pages

    When I woke up this morning, after I brushed my teeth, looking in the mirror, I thought to myself ; “what am I putting into my body that shouldn’t be there?” The answer to that question is the processed foods that large food corporations sell to us consumers and make us think that we are eating healthy and nutritious foods when we are eating processed foods filled with preservatives to make them last longer. As a consumer, if I buy a food item, I would think that this product is safe for my family and I to consume, but what’s the point of purchasing that product if that guarantee is not there. Why would you want something in your food that would make that food item look the same way after its natural expiration period? These additives are chemicals that corporations agree to add to make foods last longer. But thinking logically, why should food last longer than the natural decomposition period? It shouldn’t, food should last the time that it naturally should last. Not only can these foods be extremely unhealthy to my body, but they can also be leading to future problems that I will have. Due to the way I eat in todays day and age, I tend to ask myself a question more frequently than I should which is What affect can food preservatives do on the human body?
