Introduction
Food preservation is defined as an action or method of maintaining foods at is desired level of properties or nature of their maximum effects (Handbook of Food Preservation, Second Edition,2007).It also prefents food from spoilage. Food preservatives are used principally in the prevention of food spoilage throughout times such as food storage, throughout distribution, retailing and use by that consumer.Using food preservatives ensures that foods shelf life is desirable to the consumer and is desirable to the cosumer in their home (Food Preservatives, First Edition,1991).Food preservation was the prerequisite to man settling down in the one place (Food Preservation Techniques,First Edition,2003).This saved people from moving from …show more content…

Canning is a method that is used to preserve food.This method could also be called sterilisation (Process In Food Preservation,First Edition,2012).This is also called sterilisation due to the high heat treatment that is applied to the food.This high heat treatment elimates the micro organism that causes the spoilage of food.In the process of the preservation of milk, pasteurization occurs.Pasturization is combined with microfiltration which can be used in the extention of its shelf life (Process In Food Preservation,First …show more content…

(Food Preservatives, First Edition,1991). Gram negative, catatalase-postive,oxidase-postitive rods.These typically dominate the spoilage of fish,meat,poultry,eggs and other protein in riched foods.These include some species that can grow below 0 degrees .These species are called psychrophic species.These have the ability to grow in a simple media and are characterzed by there such ability to metabloize a wide range of organic compounds.Acetobacter and Acetomoas oxidize ethanol to acetic acid in alcoholic beverages and souring of fruits. (Food Preservatives, First Edition,1991). The Gram positive catalaste-postive cocci include many many organisms that are commonly found on animals skins and due to this it is very widespread.This is because aniamls mingle with humans and they contract this from them.These are also often found in milk products and these are slowly selected for high salt cured meat products.

    Identification of bacteria within Unknown Culture #21 In this experiment, an unknown culture of two different types of bacteria was assigned to each person, a number of tests were performed to isolate and identify these bacterial cells. Based on knowledge from the previous experiments completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test.

The MacConkey agar plate and the Mannitol Salt agar plate are both used in the identification of the unknown. The MC plate is a selective and differential medium. It is considered a selective medium because the bile salts and crystal violet aspect of the medium prevent the growth of gram positive bacteria (3). This medium is differential because of the lactose and neutral red.

    Staphylococcus epidermis produces the enzyme catalase. In the PEA Agar, a catalase test was performed which showed that the organism produced catalase. Staphylococcus epidermis is not a mannitol fermenter. Mannitol fermenting organisms grow on the Mannitol Salt Agar. The unknown organism is not a mannitol fermenter because it did not grow on the Mannitol Salt Agar.

Adding to this issue were the harsh conditions in which the workers were forced to work in.

    In the laboratory, identification of an unknown bacterium is often necessary. In the lab, a random sample consisting of three different bacteria was selected. The sample contained one gram-positive, one gram-negative paracolon, and one gram-negative coliform. The purpose of the experiment is to identify each of the three species that the mixture contained. After receiving an unknown mixture, the sample was streaked for isolation onto TSA, blood agar, and MacConkey plates.

    Food Deserts Food deserts are spaces that are at least a mile or more over from any super markets and/or shopping centers. They are usually located in places where most of the people who live there do not have reliable transportation. Most businesses in food deserts have corner stores and fast food restaurants, but there usually are not any healthy food places or choices in the area. Supermarkets have been harshly judged for leaving out a large population of the Black and Latino population in cities such as Memphis, Los Angeles and Detroit. These cities are desperate for more healthy food besides the many fast food places they have to offer.

    Everyday food Abstract The article discusses the role of food as an instrument of identity and a channel of contact through cultures. This is discussed drawing from three cases of Italian food culture hybridization spanning from the early 20th century to the first decade of the 2000s: the role of Italian food in Italian-American identity as depicted in Leonardo Coviello’s work; the meeting of Southern and Northern food cultures following the Italian internal migrations in the ‘50s and ‘60s; the food practices of international migrants in the context of the global flows of people and commodities in present day Italy. In this regard, food plays an essential role in the rebuilding of a familiar context in which migrants can feel temporarily

    In order to utilize casein, bacteria cells secrete proteolytic exoenzymes (amylases, proteases, pectinases, lipases, xylanases and cellulases) outside of the cell that hydrolyze the protein to amino acids. The amino acids can then be used by cells after crossing the cell membrane via transport proteins [169]. Starch hydrolysis test is used to differentiate bacteria based on their ability to hydrolyze starch with the enzyme α-amylase or oligo-l, 6-glucosidase. These enzymes hydrolyze starch by breaking the glycosidic linkages between the sugar subunits. It aids in the differentiation of species from the genera Corynebacterium, Clostridium, Bacillus, Bacteroides, Fusobacterium and members of Enterococcus [170].
