MICROBIOLOGICAL SAFETY OF PHYLLO PASTRY
INTODUCTION
Contemporary trends in food industry are based on balanced diet, which provides a good health and prevention of disease. Wheat based products are ingredients which are characterized by an optimal amount of basic nutrients. Wheat products are rich in carbohydrates, proteins, minerals, vitamins, and other nutritious materials, moreover they’re well known as a highly nutritious food. Different kinds of wheat participate in a human diet. The demand for the products such as whole grain flour and whole grain products from various flour is in a constant increase.
In the world, as well as in our country, pasta related products are present in human nutrition on a daily basis. Production of pasta

The fresh pastry products such as phyllo pastry, due to high water activity value (aw>0.90) presents a good environment for the microorganisms growth and development. Microbiological population of phyllo originates mostly from the flour. Whole grain wheat flour poses the higher amount of kernel bran in comparison to flour T-500. The most frequent contaminants of flour and their product are molds. On the base of obtained results it could be concluded that usability and shelf life of fresh phyllo pastry has to be limited to 7 days for wheat phyllo pastry and to 5 days in the case of the whole grain wheat phyllo pastry, at the temperature of 8⁰C.

Winnable Battle- Safe Food Objectives: Approximately 1 of 6 people in America get sick from eating contaminated food. Some people recover and few others may suffer from complication such as kidney failure, miscarriage or brain and nerve damage (10 Colorado winnable battles). In Colorado, there is at least 41% of foodborne outbreaks report and investigation each year. This is an enormous number that underscores the need for vigilance and highlights the importance of the food safety programs to identify foodborne illnesses (10 Colorado winnable battles).
A milk-based, litmus broth tube is incubated and observed after 48 hours. Observations include lactose fermentation without gas as well as with gas, the reduction of litmus, casein protein coagulation and casein and protein hydrolysis. These characteristics were all determined based on the color of the solution and the production of a curd, the curds density and the production of a gas. To determine the density of the curd, the tube was slightly turned to see rather or not it was mobile or concentrated towards the bottom. 2.3 Carbohydrate Fermentation of Lactose, Sucrose and
Food is the sustaining life force that drives the human race forwards from day to day. As daily consumers of food products, it is automatically expected that the producers of such important products aim to produce goods that will help the consumer and attribute to their health. Unfortunately, this is not always the case. At the turn of the twentieth century, food sanitation in factories was at an all time low. Adding to this issue were the harsh conditions in which the workers were forced to work in.
The lipid A has phosphoethanolamine added to it, which in turn, inhibits the bacteria from any attachment. Q3E: What is the origin of the mcr-1 gene, and what evidence do the authors use to support this
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.
List the various types of baked products they are used in, describing there effect on the individual products. Malt Flour: This type of flour is a special ingredient for bread makers as it promotes a strong rise, a lovely texture and a brown crust which makes the product more desirable. The active enzymes in the flour make sure that during fermentation the products grows effectively and have a good oven spring. It also helps the bread stay fresher.
Tn 4351 was originally isolated from bacteroides fragilis [30] . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation [25]. Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed in aerobically grpwn E. coli, but not in anaerobically grpwn E. coli or in bacteroides.
The Another medium used was MAC, it is used to isolate and differentiate gram-negative organisms and it is a pink, dusty rose color. Lastly, the Citrate Slant is a green color and it was used as a differential test to examine enzymes. The media were inoculated at 37°C for 48 hours, then it was observed to determine the
What is the effect of temperatures 10°C , 20°C, 40°C, 60°C and 70°C ± 1/°C on yeast fermentation when baking bread? ii. Aim: The focal aim of this experiment is to investigate the effect that temperature has on the growth and respiration of yeast (Saccharomyces cerevisiae) fermentation. iii.
This is launched to enhance the understanding of the role of Microbiome in the ecology of humans and using the concerned knowledge in the development of therapies for various illnesses (About MGH, nd, News Releases). The department of chemistry and biological engineering, and MIT institute of medical engineering and science are involved in collaboration with MGH clinical medicine. This new partnership will follow the one that was implemented among MIT, Ragon Institute of MGH and Harvard, which started in 2009 and worked on developing effective vaccine against AIDS as a part of their study on the role of immune system in human disease (MIT News, Oct. 15, 2014). This new partnership between MIT and MGH has offered $3 million to a two-year period research project dealing with the problems in diagnostics, autoimmune and infectious diseases and in
The aim of this study conducted by Zimbardo was to investigate how readily
My knowledges of molecular biology, biochemistry and microbiology have grown, but I know there is a lot to learn and, as always, to keep learning is my final goal. This is the moment to challenging myself and pursuit other experiences in an area that involve Biochemistry and Molecular Biology. I want to continue my education at the Graduate Program in Biochemistry and Cell Biology at Rice University. This program is the best option to continue improving my scientific and professional skills. The privileged research conditions of your university, the facilities, the faculty and the outstanding researcher lines make this university the perfect place for a doctoral training.
Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
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].
Using chitosan as a food preservative allows for reuse of this waste, making its use environmentally beneficial; while also reasonably cheap and cost-effective in production and usage. - Its biodegradability also allows chitosan biofilms to be beneficial to the environment. - The chitosan film has antibacterial and antifungal properties, meaning that it ultimately prolongs shelf-lives of the foods which it coats. - As chitosan film is a polysaccharide which physically coats the food product, it offers the advantage of being edible,
