Food Preservation Essay Example for Free

Food Preservation Essay Men have preserved their foods from ancient times in order to keep the results of harvesting for winter months, for resale, for storage, and for transporting from sea to inland, overseas, or cross-country. To do so, they generally used natures methods, which are drying, parching and fermenting. Parching is the most natural method, but for many thousands of years, others have also been used. Direct fermentation of liquids, usually by the introduction of yeast, has not only preserved liquids but also enhanced their quality, the same of course applying to salting. Smoking has preserved, and sometimes improved both fish and meat. Hickory wood is generally used for the fires, and natural juices are contained by a slight coating of wood creosote. It was not until recently that the causes of rottenness were understood, these being the reactions of bacteria, molds, yeasts and micro-organisms. Some fermentation and molds are, of course, necessary in the production of food and drink; molds, for example, being used in cheese-making. But the real breakthrough in preservation against the causes of rottenness came, when it was learnt how to deal with the micro-organisms present in all foods and drinks, and which react chemically over a period to produce unpalatable or poisonous food or drink. There are three basic methods. Firstly, food may be preserved by cooling or freezing, to a very low temperature when long-term preservation is required. This was originally done by packing in a mixture of salt and ice; today, cold storage is big business and refrigeration is a highly-developed science. Dehydration may be bracketed with this method, as the principle involved is the same, namely to suspend the operation of bacteria which requires normal temperatures for chemical reaction. This is why reconstituted eggs cannot against dehydrated, and melted ice-cream refrozen. The second method of destruction is by heat-processes, which destroy all the bacteria present in food and drink. This process is used before canning foods in hermetically-sealed containers, great care being taken not to allow the foods or drink s to become re-infested after cooling and before canning. The third method is to preserve by the addition of chemicals, which control or destroy bacteria. This is merely a follow-up of the old systems of salting, smoking and candling. Eventually, the method of cold sterilization is expected to supersede most of the others; this amounts to exposing the food-stuffs to ionizing radiation. Today more than mere food-preservation is sought by the consumer, and for this reason, processes are becoming more and more sophisticated. Quality, economy and convenience are sought by modern man especially modern woman convenience is important, the ready-cooked meal is popular, while, in Western, or Westernized communities, goods do not sell easily if they lack color, a good appearance, natural flavor, the right texture, and are free from defects.

“My brother, my sister, and I”

The quite an engaging story, the book describes an event in the author’s life. Yoko, then 13, her 17-year old sister, and 21-year old brother became refugees to post World War II Japan. Hoping for the better life, they escape from North Korea only to find extreme hardship in the new land. The novel does not feature the series of quick actions but is able to transfer real-to-life feelings and emotions of the sibling trio. In quite a charming way it tells how these three young people settled down in their first desolate home, owners of which were nice and kind people. Especially the meaningful were their interactions. However, the terrible fire in the warehouse kills their landlords and puts one of the siblings in a hospital. In addition, their problems are multiplied by a terrible blame of the setting the fire and killing the kind couple. Homeless and hungry they fasten together, spending most time in the hospital room by the bed of their sibling. Yoko, once the product of the middle class family, experienced homelessness, hunger, terrible treatment by her classmates, and at times impossible despair. Her mother has died, her father was a POW, and seeing as her two older siblings had to clean toilets to get scraps for her to survive was beyond desperation, but full of humility. This novel teaches us how important the family ties are, those that despite of, at times, very difficult circumstances in life, help us survive and make better of ourselves. This novel also teaches us, that despite the adversities, there are people who are wiling to help, like an odd Burakumin couple they met under the bridge. This novel is about how people, especially young people, can preserve their dignity despite impossibly difficult circumstance that at time life presents. I impression of what I read was not about the adventure this trio experienced but about the yielding motif, â€Å"White righteous men should suffer?† References: Watkins, Y. K. 1996.

Causes and Factors of Homosexuality Essay - 603 Words

There is a group of people who are only attracted to the same genders. They still haven’t been completely accepted and approved by society. The world regards them as abnormal; the Bible defines being homosexual as a sin. The homosexuals have been fighting for their right of being treated equally for many years, and so have some others who support and embrace ones who have different sexuality. Their only aspiration is to prove to the world that homosexuality is not a sin. There’s a great deal of factors resulting in homosexuality. And they all demonstrate that there’s nothing wrong with being a gay; instead, it’s just a different way to live a life. First of all, homosexual desire is mostly caused by exoteric factors.

The son hopes that having a sexual relationship with a man he perceives to will make him feel whole (Mantyla 2). What’s more, unusual sexual experience may lead to preference to the feeling and behavior of being homosexual. For instance, precocious or excessive masturbation, exposure to pornography in childhood, depersonalized sex, or girls, sexual interaction with adult males (Cameron 13). Besides exoteric factors, biological factors can also incur homosexuality. Above all, it’s already been proved by American Psychiatric Association in 1974 that homosexuality is not a mental disorder (Swidey 15). Subsequent studies by Pillard and others have confirmed the clustering among siblings. â€Å"In Pillard’s early data, a bout 22% of the brothers of gay men were reported to be gay or bisexual, compared with about 4% of the brothers of straight men. Similarly, about 25% of the sisters of lesbians were reported to be lesbian or bisexual, compared with about 11% of the sisters of straight women (LeVay Ch6).† Typically, about 7%—16% of the same-sex siblings of gay people are found to be gay.
