What has been the impact of food processing on sustainability of the food system, and thus, the global population?
Food processing methods, such as preservation of food to delay spoilage or deterioration, refrigeration, as well as canning or other forms of packaging, have helped sustain the food system by allowing perishable food to be transported across long distances. Since most of the global population now lives in urban areas as opposed to rural areas (where most of the food production takes place) these methods have ensured that food can be safely transported from the rural areas of production to the urban areas. By increasing the shelf life of food and ensuring that food reaches these urban areas, the global population has been able to successfully thrive.
During the Green Revolution of the 1960's, which of the following was not a major component for the increase in food production: A) Irrigation
B) Using more Land
C) Pesticides D) Fertilizer
B) Using more land
The earliest signs of agriculture was thousands of years ago, but the population didn't seem to increase exponentially until much later on. Explain the link between agriculture and population growth and why the population boom didn't occur at the same time agriculture was introduced.
Before agriculture was introduced, humans were hunter gatherers, meaning they would have to eat whatever they could find, move around constantly and put all their resources into finding food. When agriculture was introduced, there was now a surplus or food in one area, reducing starvation and allowing for the formation of settlements. This could have caused a slight increase in population due to better nourishment and quality of life, which slowly increased along with the increased use of agriculture throughout the world. The large increase in the population over the last 200 years, however, is more likely due to the better technology and medicine contributing to a lower infant mortality rate and increased lifespan, rather than having a direct link with the introduction of agriculture itself.
What are examples of food processing, and why did food processing increase in demand beginning in the 1950's?
Examples of food processing that allow increased food preservation include refrigeration, freezing, smoking, canning, and freeze-drying, all of which were deemed necessary as the percentage of people living in urban areas increased, and the percentage of people living in rural areas decreased.
Two significant quotes were shared during the Lecture "Feeding 9 Billion People" that supported the question "why study food science?" Finish these quotes with the appropriate responses: (1) "how we ____ food has a bigger impact on Americans' _____ than any other human activity"

2) the ___ is the ___ sector of our economy: food touches everything from our _____ to the environment, _______, economic ____ and the ______."
1) produce and consume; well-being

2) food industry; largest; health; climate change; inequality; federal budget
How did homo sapiens transition from being nomadic to living in civilizations?
When the transition to agriculture began in 11000 BCE, humans began to grow grains in the Fertile Crescent. This ability to produce food instead of hunting and gathering helped humans form civilizations (instead of being nomadic) since the source of food would no longer have to vary in location with the time of year.
According to the research presented in the last chart we were shown in the first lecture, American diets are very skewed in that we do not eat enough of certain types of foods in our daily meals. According to the results of the survey, current eating patterns in the United States estimate that ____% of Americans do not consume enough dairy on a daily basis: A) 25% B) 45%

What are the 6 different parts of the Food System?
Food Production, Food Processing, Food Transportation, Food Retailing, Food Service and Home Preparation, and Consumer Food Choices
Paul Ehrlich wrote The Population Bomb in 1968, in which he warned that mass starvation would occur in the 1970s and 1980s; however, this did not occur. What is one possible explanation for why Ehrlich was wrong in his prediction?
One possible explanation is the advancement of agricultural technologies. Plant breeding allowed for a higher yield of wheat and rice to be produced on the same amount of land, leading food production to greatly increase. In addition, the inventions of fertilizers, pesticides, and better irrigation allowed for a higher percentage of crops to be unharmed by the environment. Another reason is the implementation of food preservation techniques. Examples of this include freezing, canning, refrigerating, and vacuum packing foods, which greatly increases the shelf life of products.
How has our diet changed as humans moved from hunter-gatherers to current times?
As hunter-gatherers, humans had little choices for food and were limited to the food in their area. However, they were able to thrive on a diversity of diets and generally had a diet high in fiber and low in energy density. This is different from today, where we have a surplus of food choices that are imported from all over the world. However, today food is usually more processed and not as nutritious and is typically low in fiber and high in sugar.
What year will the population reach 9 billion?A) 2030 B) 2040 C) 2050 D) 2060
C) 2050
What is the largest consumer of freshwater in the world?
Agriculture is the largest consumer of freshwater, using approximately 80% of the world's supply in order to irrigate crops.
Describe the consequences of the majority population shifting from living in rural areas to living in cities. Include a challenge it presents to the food system and an example of a technology or method used to overcome it.
As the majority population shifted from living in rural areas to living in cities, people moved away from the mass farms which are the center of food production. This created challenges in food spoilage, storage, and transport. To combat food spoilage and storage, methods for drying, freezing, freeze-drying, refrigerating, canning, and vacuum- sealing perishable foods are used.
What is the Green Revolution, its effect on mass starvation, and a country that benefited from it?
Founded by Borlaug in the 1960s, it was the change in using shorter stem varieties of wheat, rice, and maize, which caused higher yields. There were also improved farming practices. This helped prevent mass starvation by increasing food per capita, saving many lives. India was no longer in a food deficit after this time.
As the human population has become more urbanized, the need for food has remained the same. What parts of the food systems helps deal with these needs?
The processing of food allows for the lifetime of food to be increased to a level where there can be transported around the United States and the globe. With this increase in lifetime, food transportation is also needed to ensure that the food can be delivered to the areas that need this processed food. These two processes allow for increased urbanization to occur, while most of the food is grown in rural communities.
What are the two types of ice cream mixes that serve as the base for nearly all varieties of ice cream?
Chocolate mix and white mix
On which day of the week is more ice cream sold than on any other day of the week?
There is a common notion that Cornell Dairy cannot commercially sell their ice cream because it has too high of a milk fat content. Is this true?
This is false. The minimum amount of milkfat must be 10 percent, but there is no regulation on the maximum amount of milkfat. In fact other brands found in the grocery store have a higher percentage of milkfat than Cornell Dairy which is only around 12%.
Why are fruits, nuts, and bulky flavorings added to the ice cream mixture after it is already frozen and why is this beneficial to the overall consistency of the ice cream?
The fruits, nuts, and bulky flavorings are added to the ice cream after freezing because it prevents the pieces from breaking. This is beneficial to the consistency because the mixture is still soft and therefore the pieces are able to be evenly dispersed throughout the product.
What is the rumor for why Cornell Dairy could not be sold off campus, why is it false, and what is the truth?
The rumor is that the ice cream fat content is too high, it's false because there is only a lower limit of 10% but no upper limit, and the truth is that it wasn't allowed to be sold off campus of the competition with the local private industry prevented Cornell from selling it off campus.
What are the top 5 ice cream flavors in the US?
Chocolate, vanilla, butter pecan, strawberry, and chocolate chip mint.
What is "Overrun"? And how does it affect the texture and the quality of ice cream?
The addition of air in ice cream mixture is called "overrun". Overrun contributes to lightness or density of ice cream texture. Premium ice creams usually have less overrun because they are denser than regular ice cream, which means less air is added.
Particulate addition should always be done: a) Before hardening and after batch whipping
b) Before batch whipping and before hardening
c) Before distribution and before air incorporation d) After distribution and after packaging
A) Before hardening and after batch whipping
A group of ambitious Cornell students are looking to make a fortune by creating a revolutionary new type of ice cream to compete in the $23 billion dollar industry. They plan to make an ice cream that will make those who eat it lose, rather than gain weight. While they are in the planning phase and are considering their ingredients, which are essential for them to include: A. The ice cream must contain at least 10% milkfat
B. The ice cream must contain at least 1.3 pounds of total solids to the gallon
C. The ice cream must contain bacteria that eats fat cells D. The ice cream must contain vanilla extract
E. The ice cream must contain a type of food coloring
F. The ice cream must have ingredients that are kosher
A: The ice cream must contain at least 10% milkfat

Explanation: According to the NYS Code of Rules and Regulations, in Part 17 Requirements for the Labeling of, and Definitions and Standards of Identity for Milk, Milk Products and Frozen Desserts: Ice cream must contain no less than 1.6 pounds of total solids to the gallon (which would eliminate option B), and must weigh no less than 4.5 pounds to the gallon. Ice cream must also contain no less than 10 percent milkfat (option A), nor less than 10 percent nonfat milk solids. The only listed ingredient that must be included in the legal production of ice cream is option A. All other options could be included in the students' recipe but are not essential for the production of their ice cream.
Why is the "hardening" step crucial to the production of ice cream?
Hardening comes right after Packaging. At that point of the process, ice cream still has a gel-like consistency. It is frozen, but is not stable yet. Quickly freezing the ice cream in a temperature of less than -13°F(-25°C) enables the most of the remaining water in the ice cream to form tiny crystals, which helps stabilize the product as well as maintain its quality. Hardening also prevents the loss of air (or overrun) incorporated in the ice cream in previous steps of the process.
Each American consumes a yearly average of ______ of ice cream, ice milk, sherbet, ices and other commercially produced frozen dairy products:

b. low; high
c. high; high d. high; low
B: low; high
What is the purpose of homogenization in the process of making ice cream?
The purpose of homogenization is to decrease milk fat globule size, which forms a better emulsion and contributes to a smoother, creamier ice cream.

What are the four P's of marketing and why are they important when considering making ice
cream? Explain one of the four P's (1-2 sentences).
A. Price, Place, Promotion, and Product. They are important to consider because better marketed and promoted items typically win against other products. And oneof the following:
Price - Determines who your product will appeal to/who your consumer market will be and the types of ingredients that can be used to make your ice cream (higher quality ingredients will require higher selling prices).
Place - Where you will be selling your product. If you have a high quality product that is more expensive to produce than other products, you want to sell it in a place where you can get away with high prices (such as an expensive chain like Whole Foods or public events like fairs and sports games, where other food items are just as expensive).
Promotion - Determining how you will get people to buy products, such as using social media like twitter or giving out coupons.
Product - If the product name, packaging, and claims of the product are attractive, the product is likely to sell better.

Using an example, explain the practice of gerrymandering. In your answer, be sure to include which of the United States Congress's chambers can practice it?
Gerrymandering is the manipulation of voting district boundaries as to provide a political advantage for a specific group. In the United States, only members of the House of Representatives can practice it. For example, the House of Representatives in Alabama could rearrange the boundaries of districts in their state so that there is only one district that has a majority of Democratic voters and the rest of the districts have a majority of Republican voters. This would increase the number of Republicans elected to the House of Representatives in Alabama, which would make it easier for the House to pass legislature drafted by Republican leaders.
