How Do Food Preservatives

With this increase in the productivity of farmers, came a proliferation of food processing industries and fast food restaurants. These food processing industries and restaurants capitalized on the abundant, overly cheap commodity crops to their advantage; to make profit, and to the disadvantage of poor Americans. During processing of these commodity crops, the natural nutrients that give these foods their natural flavors are destroyed. To replace these, food additives and flavorings are added to restore their taste and prolong their shelf life. Often these chemicals contain some harmful elements that affect the way our bodies use food. These highly processed foods, dense in calories,

To begin with, food additives should be clearly explained and understood that food additives are any substances found in food that is not a part of the normal ingredients. (Chris Hayhurst, 2002) There are six kinds of additives. The six kinds are nutrients, flavoring agents, coloring agents, preservations, emulsifiers, stabilizers, thickeners, acids and alkalis. (Graddy W. Chism, 2006) These six are both good and bad. Nutrients such as minerals and vitamins, which make food more nourishing. For instance, adding of the B-complex vitamins folic acid and niacin to flour, pasta, and rice has helped reduce the

The government masks what is put into our food. The Food and Drug Administration (FDA) certifies the use of partially hydrogenated oils, high-fructose corn syrup, butylated hydroxyanisole, propyl gallate, potassium bromate and many other additives for a sustained shelf-life and stabilization of flavors. These additives have been directly

Food hygiene is very important to prevent cross contamination. If strict guidelines are not adhered to in the handling of food serious illness can be caused.

What is Food Preservation, exactly? It is the act of preserving food, maintaining its best quality for a given amount of time; other than that, it is a field of science that is dedicated to the lengthening of food shelf life, maintaining better food quality and taste, ensuring the safe consumption of food through the control of the biological, chemical, or physical factors and many more.

In light of my previous response I can conclude that salt is formed from the

Even though people are aware of the importance of cleaning their homes, majority do not comprehend how cleaning can reduce the level of bacteria in their meals. Also, a lot of Americans undercook their meat, chicken, and egg. Most do not understand, or find it difficult to understand the safe food handling instructions on the labels of the products they buy. They even do not keep to the recommended requirements when storing food in their refrigerators. Since proper food storage reduces the rate of bacteria growth, the refrigerator temperature should be set to between 32F and 41F. (Bruhn, 2014, p. 319, 326)

Dr. John Coupland is a professor of food science and the Chair of the Ingredients as Materials Impact Group at The Pennsylvania State University. Dr. Coupland instructs undergraduate and graduate level courses while also actively researching various aspects of food chemistry. However, before arriving at Penn State, Dr. Coupland obtained both his B.S. and Ph.D. from Leeds University in the UK.

It has been changed for the consumer to enjoy with convenience (“Eating”). They usually contain preservatives, colorants, flavorants, and/or texturants (Gunnars). These are used in foods to achieve “product optimization,” or satisfying the consumer (Moss). Examples include, but not limited to, potato chips, cookies, bread, TV dinners and cereal. Although people claim that processed foods are safe because of their consumption rate, they are the cause of many health issues in America.

Food is preserved to prevent spoiling and prevent alterations in their taste or appearance. Anti-microbial substances are used to inhibit or delay the growth of bacteria yeast and moulds (Food Today 2004).

With new advances in technology and innovations in the medical field, the implementation of chemicals and preservatives into consumables has changed the way food is manufactured. Recently, negative light has surrounded the products that include these additives. More specifically, the consumption of nitrates and nitrites has caught the attention of many and led to further investigations concerning this topic to decipher the possible health risks or benefits that can come from their ingestion. The usage of nitrates and nitrites in products has a negative connotation, however, it only poses a threat in specific conditions, and is otherwise proved to have beneficial and common traits. These specific

One of the most serious, harmful additives is aspartame, which is more commonly known as Equal and NutraSweet; it is a neurotoxin and carcinogen that may lead to a wide variety of ailments including brain tumor. Dr. Farlow declared in an interview she had with Norma Lehmeier Hartie of Harmonious Environment that, “Almost any symptom can be a result of a food additive… Aspartame has been associated with 92 different adverse reactions…”

Restaurants in particular, have to be very cautious to prevent their customers from being served contaminated food. Not properly handling meat or cross contaminating can cause food-borne illnesses or even death. A story reported in 2013 described an incident where 80 people became sick from improperly handled food (FoxNews, 2013). Their report demonstrates how easy it can be for people to get sick if food is not handled correctly. One of the most important parts to handling meat, is figuring out the safest way to thaw meat in order to prevent bacteria and disease from growing before cooking it. Although the bacteria is killed when heated above a certain temperature, it can still cause harm if not properly handled. This experiment will test the different possible methods of thawing meat to prevent disease and bacteria from spreading before

Food is an essential constituent in human life. Nevertheless, some foods can be detrimental to a person’s organism by causing life-threatening diseases. For that reason, food safety comes into play. Food safety is a scientific discipline describing handling,

According to historical records, natural methods of preservation, such as salting or dehydrating, have been around for centuries. When humans began to switch from hunting and gathering to a more agricultural approach, they needed a way to make food last for longer periods of time. This became an obvious problem as food
