History of Food Preservation Methods

History of Food Preservation Methods Yasmine Dabash The Sustainment of Foodstuffs Over the Years Isn’t it nice to go home and microwave a frozen TV dinner after a long day of work? Without the invention of food preserving technologies such as the refrigerator or the freezer, such would have never been possible.This is because both technology and science are interdependent on one another. Since ancient times, food has been preserved in a number of ways including refrigerating and heating, drying and salting, and canning and jarring. Over the centuries, the human race has been equipped with superior knowledge thus enabling us to continually improve technology. It is common to see technology morph to adequately fit updated knowledge, A common example of this is cell phones which often update with more features in more condensed models. Food preservation today is the result of many hundreds of years’ worth of work towards the sustainment of foodstuffs. Most mediocre households contain a refrigeration and freezer unit which is used daily to preserve foods for an allotment of time. Refrigeration has a particularly long history’ for many centuries, people would carve large blocks of ice from nearby fresh water sources and put it iceboxes, which they used to keep their food cool. Even today in remote Amish-culture societies, people use this technique of refrigeration. Around the same time, people would store their produce in 30-40Â °F root cellars. It wasn’t until 1918 that the first Frigidaire was created then mass produced. Then twelve years later, the eco-friendly, Freon-less refrigerator model we used today, patented by Albert Einstein and a colleague, was introduced. (findingdulcinea.com) Twoother modes of food preservation which have a long history, primarily in hot climates of the world include drying and salting. The methods of drying and salting to preserve fish, meat, and vegetables were been predominate in dry, hot climates (ie. the southern states of America) for hundreds of years. One of the most common ways of curing meat is salting, which has been carried out since ancient times by packing meat in heavy amounts of salt in barrels; this method of meat preservation was not replaced until the times of advanced freezing and refrigeration. Drying meat, another popular mode of meat curing, has a goal of simply evaporating the liquid content of the meat. This is because microorganisms need a certain amount of moisture to survive in an environment, so by removing the water content from the meat you are thus making the meat unlivable for the bacteria which causes spoilage. (fao.org) This is also the same reason dried fruits (raisins, dried apricots, Craisins, etc.) last a longer time than its fresh form. Food can be preserved for long term storage through the methods of canning and jarring. By canning and jarring food you are sterilizing then inhibiting bacterial growth in the food, therefore lengthening the longevity of the food’s shelf life by far. Usually vegetables and meats are packages in sealed tin cans rather than jarred; some common examples of canned foods are corn, tuna, processed beef, and soup. Jarring is also a ordinary way of conserving pickles, jams and jellies, baby food, and tomato sauce. Fermenting foods by storing them in a vinegar and salt brine within a sterilized glass jar is called pickling. Pickling is an endeavor practiced to preserve mainly vegetables (most commonly cucumbers). Unfortunately this method increases the salt content and lowers the vitamin content of the foodstuffs preserved. Preservatives can often times be added to foods to foods to make them last longer. Sometimes, when processing foods, preservatives are added to help conserve the foods by killing bacteria or slowing bacteria activity. These preservatives come in four major categories; benzoates, nitrites, sulfites, and sorbic acid. Sodium benzoate is a salt commonly combined with acidic and carbonated products including juices, sodas, salad dressings, and others. Sodium nitrate, although controversial now, is a naturally occurring food preservative found in salt, sugar, vinegar, and alcohol. Sulfites, although banned from fresh, raw eaten produce, is used when preserving dried fruits and dried potato products. Sorbic acid is the most used food preservative in the industry as it is considered the safest of the four common preservatives. It is known to prevent the growth of fungi, yeast, and mold. Sometimes preservatives are dismissed and limited by the United States Food and Drug Administration (FDA) to improve the overall health of our foods, which is the number one concern when it comes to food and food preservation. There are a variety of organizations and universities that support and research into the study of food preservation. The National Center for Home Food Preservation, based at the University of Georgia, primarily focuses on the preservation of produce and what safety regulations and methods should be carried out to ensure safe, convenient preserved foods both domestically and industrially (nchfp.uga.edu). Even the most unexpected can contribute to a cause; the United States Atomic Energy Commission majorly brought the rise to the use of irradiation to preserve food, especially for NASA (The NationalAeronauticsandSpaceAdministration) astronauts to eat whilst in space. Although it may seem ridiculous, the Mayflower Trading company is the largest online store for long-lasting, storable foods, emergency preparedness, and alternative power. It may seem like the go-to site for the impending zombie apocalypse but its contributions towards the longevity of preserved foods (mainly canned) are remarkable. On the topic of contributions to the field of food preservation, there is a whole list of remarkable indiv iduals who have majorly impacted food preservation as we know it. Many people have contributed to food preservation as will including the renowned Louis Pasteur. Louis Pasteur created the method of pasteurization which ensures the sterility and safety of our milk and other milk products even today. Nicolas Appert might as well be known as the ‘Father of Jarring’. Nicolas Appert came up with the concept that by heating and sterilizing a product then placing the substance in a sterilized, air-tight jar would make is long-lasting and sterile after a decade of experimentation in the hopes that he would gain recognition by Napoleon for his works. Napoleon awarded Appert with a good deal of money for his findings and used this new knowledge to his advantage by sending sterilized, preserved foods with his armies. Another recent man to make his name in history for contributing to food preservation was Daniel Farkas, a former food scientist. Farkas discovered high-pressure preservation which kills bacteria and pathogens. This method of preservi ng food is also known as pascalization and bridgemanization (oregonstate.edu). Over time, methods of food preservation have improved vastly to conform to our modernized world. Now more than ever we are able to store foods for years upon years without it going rancid. Plus, it I simple to use and effective, it is easy enough to store your food in the refrigerator, whereas in the eighteenth century you would hve to keep your food in an iebox outside of your house. Even so, Food producers should aim toward maintaining not only the food itself but also its nutritional value. Most means of food preservation, such as pickling, salting, and freezing diminish the nutrition of the food you eat. The more fresh foods we eat, the closer we may become to optimum health; hopefully in years to come we will be able to not only conserve food but also nutrients.

The Global Pharmaceutical Market Forecast Essays -- International Phar

MARKET OVERVIEW The global pharmaceutical market is a multibillion-dollar industry. The 10 largest drug companies control over one-third of the market, several with sales of more than $10B a year and profit margins of 30%. Six of these companies are based in the U.S. and four are in Europe. It is predicted that North and South America, Europe, and Japan will continue to dominate by accounting for 85% of the world’s pharmaceutical market. Companies currently spend one-third of all sales revenue on marketing, which is roughly twice of what they spent on R&D (â€Å"Pharmaceutical Industry†). The cost of innovation proves to be very high as the drug business is very risky; 1 out of 10,000 discovered compounds are approved for sale. Since 2001, the Center for Drug Evaluation and Research averaged 22.9 approvals per year. Only 3 out of 20 approved drugs bring in adequate revenue to cover the R&D costs and only 1 out of 3 approved drug generate enough revenue to cover previous failures. Accor ding to a study by Bain & Company, the cost of discovering, developing, and launching a new drug rose to approximately $1.7 billion in 2003, taking into account opportunity costs, marketing, and other business expenses (â€Å"Pharma Markets†). SUPPLY The major factor affecting supply is the advancement of technology. The development of simulation and data analysis tools condenses the drug’s process time from development to full-scale production. Process tomography and high frequency camera systems help hasten products from clinical trial stage to commercial availability. Integrated sensors are being used to monitor the performance and quality parameters of drug manufacturing processes on a real-time basis in order to ensure the quality of the medicine ... ...http://www.who.int/trade/glossary/story073/en/index.html>.

Essay on Renting Hearts Essay

Science fiction is a genre, whose stories take place in an imaginary environment where science, and in particular the technological development has undergone more or less significant changes with effect on both society and individuals. Science fiction is based on more or less imaginative themes of science results and ways of looking. The topics are often about high tech future societies, space travels, time travels, creatures, end of world, different universes etc. [1] The short story takes place in the future where the technology has taken over, and where people can buy their happiness for money, and that human now just can go to a rental shop and get a new heart in order to avoid pain When you fall in love, often you will get or end up with a broken heart. It happens for almost every one, who gets in relations with other people. But in this short story, you can get out and rent a new heart, and meet other relations without having any fear of getting hurt. The short story is about a person that has been in love with a lot of people, and then tries to not getting hurt. When he/she is getting hurt by the relations she/he goes through, he/she keeps going to the â€Å"rental place†, every time he/she falls in love, so instead of dealing with some of the pain and letting it get worse, he/she just visit the rental place and rent a new heart. There is no information or any descriptions about the main characters sex, but I would say that it is a teenage boy because he does not appear to be dramatically, and does not describe the actions detailed, as a girl would do generally. The main character is a teenager, since a typical teenager would say â€Å"And our love was going to last forever, which at our age meant six months. † It starts with his first love with Jacob, where he was very much in love with him, and they were happy for each other. â€Å"†¦ first heart. Jacob was as solid and golden as a tilled field, and our love was going to last forever, which at our age meant six months. Every time Jacob touched me, I felt my heart thud wetly against my lungs. But in the last, Jacob left him which broke his heart. . A year later he meets Anna, who is a girl. She tells him to go and rent a heart so he may be able to fall in love, because he is afraid to fall in love, since his heart has been broken before. Renting hearts made him not to feel any pain again, because of this opportunity to rent a heart. Teenagers are often confused, and a lot of things don’t make sense, especially love and relations. They fall in love quickly, and as they fall in love, they can easily fall off again. Throughout the short story, he meets both men and women, which says that he is bisexual. It may also be quite normal in this society, in the future, where you in fact can simply buy a new heart, where it is possible to try anything without noticing any consequences, otherwise it may be because he is confused about his own sex and therefore he is trying to figure out his relations to both men and women. The main character seems to have it difficult to find a balance in his life, because he cannot live without being with a regular partner, or without having someone who loves him. He cannot even manage to break up with a partner, and naturally calm down, and it is pretty hard for him, where he will feel sorrow for a long time, which he cannot stand, and therefor has to switch his mechanic heart, to get in better conditions and save himself from the pain. Another problem with the main character is that he cannot incorporate his feelings, especially with regards to be an open person towards his relations properly. He fall in love, without looking for his partners criteria, and even don’t find out if the partner matches his expectations, but will instead end up in relation without any feelings and without any fear of falling in love and get hurt. I don’t think that he lives under a safe environment with values such as family, friends or work, or a stable structure. That is what I assume. He is actually locking himself out of the truth, and he knows that his actions are wrong, so he make himself renting hearts as a facade but is still feeling bad about his life because everyone who rent a heart will realize that pain isn’t just in the heart, but also in the mind, and it cannot be obviated.

The Sociology Analysis of Food and Food Ways Essay

Sociology is the study of society and people. Food and food ways are often elements associated with particular societies and therefore, studying such a topic can offer valuable insight into the ways of that society and the people who live in it. Although eating is a vital part of survival, with whom, how and where we eat are not. Studying such ways can illustrate and represent the identity of a person or group. The nature of people and their beliefs can be indicated when analysing their food habits. Who individuals eat with is a particularly revealing factor into gaining an understanding of their identity, culture and society (Scholliers P 2001). For this reason commensality is a term frequently used in sociological research concerning†¦show more content†¦However, there are many kinds of social relationships and because of this, there are different types of commensality and each is important and offers significance in its own right. An example of commensality which the majority of people experience first happens within the household among immediate family. Sitting around one table at dinner time as a family became a societal norm during the 1800s. Since then everyday commensality among families has continued to be portrayed as an ideology, especially through the media (Lupton 1996). Such implication influences the attitudes of those in society. This is reflected in a study conducted in Scotland. Findings were that there was a general agreement in that a good meal was prepared by parents, served to children and eaten together around one table (Blaxter M Paterson E 1983). Although family commensality may be enacted as an obligation to fulfil society’s expectations, its experiencers still have much to gain from it. The effects in which these gains have on a person’s life means that family commensality is a happening of great significance. The significance of family commensality within the household is that it is the foundation of the socialisation process. Family meal times are therefore, most significant and beneficiary for the children involved. It acts as one of the events in which parents acculturate their children to everyday norms and values. Meal times are often whereShow MoreRelatedtheories of sociology1205 Words   |  5 PagesRunning Head: CLASSIC THEORIES OF SOCIOLOGY 1 CLASSIC THEORIES OF SOCIOLOGY Abstract The purpose of this essay is to discuss the three basic theories of sociology.
