Final

We believe food labels should include additives so that consumers can make an educated, informed decision in regards for what they believe is best for them and/or their family. Consumers should also be aware of the consequences that food additives may have on them. Some studies show that additives may cause hyperactivity in kids and some people might have a certain sensitivity of FD&C Yellow No. 5 in foods. Consumers might also be interested in knowing that large amounts of insects and carcasses of animals who have died of "natural causes" are in the food they consume on a regular. Weather it be anything with a red dye made from insect blood or sugar which is filtered with cow bones. 
The benefits of food labels are informed consumers, people will be more aware of what they consume which is reaching for a healthier America. If people were to know of all the unnatural things that go into their everyday food they are most likely to choose a much  health conscious decision. Although some people might still continue eating the same thing, others will have a choice as to what they consume instead of blindly stuffing their faces with things they don't know. If food companies are more honest with their customers they might see an increase in sales, especially if they have nothing to hide. 
The only risk we see in not labeling additives is the food companies losing money in fear that people will no longer buy their products. Which is understandable but food companies should strive for much healthier and safer ways of making their food. Consumers and big companies should work together to make food safe, affordable, and delicious so that everyone is satisfied without questioning what was killed going into a few jelly beans. 
The Consumer-   Food additives are substances added to food to preserve flavor or enhance its taste and appearance. Some additives have been used for centuries. According to Wikipedia the advent of processed foods in the second half of the 20th century, many more additives have been introduced, of both natural and artificial origin.Organic substances such as salt, sugar, vinegar, alcohol are also applied as conventional preservatives. These are utilised in both raw too as cooked food stuff to increase the shelf value of food so that aroma, taste as well as the meals itself may be stored for a longer period of time.     Additives are used in foods for five main reasons:
                      To maintain product 
                      To Improve of maintain nutritional value
                      To maintain wholesomeness
                      To provide leavening or control acidity/alkalinity
                      Last but not least to enhance flavor or impart desired color
   Adding food additives also have their disadvantages:
                     Some food additives are toxic if a large amount is used, e.g. sodium benzoate and benzonic acid
                     Some food additives may be carcinogenic, e.g. sodium nitrate has been shown to cause cancer to mice and may also cause cancer to human beings
                     Some additives may have side effects such as allergies
Yet not everyone has these side effects , therefore I believe that food additives should be added however the amount of each substance should vary. Salt and Sugar can cause more harm than all the other additives combined .
              As a consumer food additives may be killing me slowly without me noticing.As great as they taste I'm not always aware of whats been added to my food.Also I believe that its not always about the great taste, texture ..etc but more about my health.

Food Irradiation


What is Food Irradiation ?
 The process of exposing food to ionizing radiation to destroy microorganismsbacteria,viruses, or insects that might be present in the food.
Benefits of Food Irradiation:
 * Disease-causing germs are reduced and eliminated
 * The nutritional value of the food is preserved
 * Reduced spoilage in global food supply
 * Increased level of quality of assurance in international trade of food products
Are irradiated foods still nutritious?
Yes, the foods are not changed in nutritional value and they don’t become dangerous as a result of irradiation. At irradiation levels approved for use on foods, levels of the vitamin thiamine are slightly reduced, but not enough to result in vitamin deficiency. There are no other significant changes in the amino acid, fatty acid, or vitamin content of food. In fact, the changes induced by irradiation are so minimal that it is not easy to determine whether or not a food has been irradiated.
Which foods can be irradiated?
* Meat
* Poultry 
* Grains
* Many sea foods
* Fruits
*Vegetables
Does the irradiation process make food radioactive?
According to http://uw-food-irradiation.engr.wisc.edu/Facts.html No. Irradiation by gamma rays, X-rays and accelerated electrons under controlled conditions does not make food radioactive. Just as the airport luggage scanner doesn't make your suitcase radioactive, this process is not capable of inducing radioactivity in any material, including food. However, not all foods are suitable for irradiation. For example, oysters and other raw shellfish can be irradiated. 
How can I tell if the food has been irradiated?

A distinctive logo has been developed for use on food packaging, in order to identify the product as irradiated. This symbol is called the "radura" and is used internationally to mean that the food in the package has been irradiated. A written description may also be present, such as "Irradiated to destroy harmful microbes". It is not required to label a food if a minor ingredient of the food, such as a spice, has been irradiated itself.



Beef & Amonia


Before reading:

1. How would you feel if you had to pay an extra fifty cents for your school lunch? 
How much would that add up to over a school year?
I would be highly upset because that's fifty cents extra for food that I dont even enjoy.Also that adds up , if I had to pay it every day.
2. Statement: I don't care what goes in my burger as long as it's cheap, tastes good and doesn't make me
sick. Do you agree or disagree, and why?
I disagree with this statement because knowing what I put into my body is important to me and just because it doesn't make me sick doesn't mean its healthy. 
During reading:
1. Why did Beef Products, Inc. begin treating beef with ammonia?
To kill E.coli as well as salmonella.

2. What happens to a batch of beef that is found to be contaminated with E. coli or Salmonella? What about if the beef is ammonia-treated?
If a batch of beef is found to be contaminated with E.coli or Salmonella the school lunch program will not buy the meat but there's no ban in selling it to the general public. If a batch of beef contains ammonia it will be classified as a "processing agent" and not an ingredient that would be listed on labels.  

3. How might the ammonia treatment process fail to kill microbes?
Ammonia treatment might fail to kill microbes if enough of it is not being used. 

4. What are the effects of the ammonia treatment process on beef odor and taste?
High doses of ammonia make beef taste and smell better to consuming customers, although its not very healthy for them.  


After reading:
1. What are the risks of treating beef with ammonia?
The risks of treating beef with ammonia is giving the general public food that contains ammonia which is not very good for the human body, putting the general public health at risk. 

2. What are the benefits of treating beef with ammonia?
The benefits of treating beef with ammonia is better smell and taste, its lasts longer and kill off microbes.

3. Do you believe that ammonia should be listed as an ingredient in ground beef, 
or remain as an unlisted processing agent?
I do think that ammonia should be listed as an ingredient in ground beef because people should have the right to know exactly what it is that they consume so they can make an educated decision about their food.

" All Orange Juice Sold In The U.S Should Be Fortified With Calcium "

From my knowledge I believe food should be modified.I say this because people need calcium, vitamin A, and so on in order to be healthy efficient human beings. Individuals who don't get enough calcium suffer long term defects , low bone mass is one of them. Not only people who don't get enough calcium in their diet suffer but also individuals who do not get enough vitamin A in their diet suffer from weak membranes around their organs making them vulnerable to diseases. However you can find nutrition in foods naturally such as in vegetables , bread , MILK .. etc yet again not everyone knows how to find nutrition in foods naturally. This is why food should be modified to make sure that everyone gets the right amount of nutrition's daily.

Ionic and Covalent Bonding

                 
Atoms form bonds when their valence electrons interact. Ionic bonds form between oppositely charged ions. Covalent bonds form when electrons are shared between two atoms.  Metallic bond has a distinctive property because it can conduct electricity when they are solids and can bend and stretch. Polyatomic ion are different from other ions because they are made of groups of atoms that are covalently bonded.
