Watermelon or Citrullus lanatus is an annual species containing cultivated, semi domesticates and wild forms, widely distributed in tropical and subtropical areas (Jeffrey, 2001). It is consumed frequently as a dessert, fruit salad and used in garnishing drinks and produce a natural source of antioxidants (Alim-un-Nisa et al., 2012).
For the watermelon juice, the storage time used is 0 hours, 4 hours, 8 hours and 12 hours. For the 0 and 4 hours storage time of watermelon juice, the dilution for plating is 10-0, 10-2, and 10-3. All of the dilution plates is duplicate to get more accurate result. The colony counting will be carried out after 24-48 hours.
For watermelon juice with 0 hours storage time for both of the sample, it shows that many

It also serves as a good medium for the growth of many microorganisms and bacteria. Bacterial contamination of raw milk can originate from different sources, including low quality raw milk, improper refrigeration before handling and an inadequate packaging system and the type of packaging the have been used to pack the milk (Richter et al., 1992; Torkar and Teger, 2008). Raw milk deteriorates in few days and pasteurized milk with high temperature short time system (HTST) has a shelf life of about seven days from it first open (Meunier-Goddik and Sandra, …show more content…
The CFU/ml obtained for the dilution is >3 x 102 (Est.). For the second dilution that is 10-1, the viable cell form on the first plate is 190 colonies. The CFU/ml for this plate is 1.9 x 103 CFU/ml. for the second plate with same dilution, the viable cell form is 72 colonies. The CFU/ml for this second plate is 7.2 x 102. The range that the CFU/ml should be is 0-9×104 CFU/ml and the CFU/ml obtained is in the range (Salman and Hagar, 2013). For the third dilution, both of the dilution shows no growth of viable cell. The CFU/ml for the dilution is <1.0 x 102 CFU/ml. Milk spoilage is an indefinite term and difficult to measure with accuracy (Lu, 2013). Consumers currently determine milk spoilage by checking the “sell by” and expired dates on milk cartons provided by suppliers. These dates are simple estimates of milk shelf life and their quality and are often inaccurate due to the variable processing, shipping, environment, temperature and storage conditions of the milk itself (Kim, 1997). Coliforms can cause rapid spoilage in milk because they ferment lactose with the production of acid and gas, and they can also degrade milk

The purpose of this experiment is to detect what kind of macromolecules are present in these three types of milk by using the Benedict’s solution, Lugol’s solution, and Sudan IV solution. Also, using the nutrition facts labels to identify which substance is skim milk, whole milk, and soy milk. Hypothesis: Using the Benedict’s solution to detect for the presence of simple sugar. If the unknown A, B, C milk samples turn from bright blue to orange color during the Benedict's test, then these samples are positive control and the carbohydrates are present in them.
Cheryl Dunye's film, The Watermelon Woman, combines elements from both narrative film-making and elements from the traditional documentary. The film follows Dunye (as a film-maker and as a character) and ventures on the journey of finding the Watermelon Woman. Whereas most of the film follows Dunye as a character throughout her life as she goes through the process of filming her finds, a few of the scenes are filmed as if the film was an actual documentary. The film is based primarily around the character Cheryl's life and adventure in finding the Watermelon Woman than it is about learning about the Watermelon Woman.
the experimenter added 5 ml of yeast suspension to each one of the ten test
Ideally the purified cellulase that was in test tube 4, which was 50 mg/ml, should have had a higher absorbance, but for unknown reasons, the cellulase has not been working all semester long. Test tube 2 had cellulase at a 1 mg/ml concentration. Next time, instead of a 1-hour incubation period at 50°C, there should be a 3-hour incubation period at 55°C. This would give the cellulase more time to break down the filter paper at a higher temperature.
To make the test fair I will use the same amount of water and the leaf
Since the beginning of time, people have been drinking milk. Even today you will find a gallon of milk in almost every refrigerator in America. Milk is, and has always been, a staple of our diet. Because it contains essential proteins, carbohydrates, fats, minerals and vitamins, milk is considered one of nature's perfect foods. Unfortunately, throughout the last century milk has been subjected to many forms of modern processing practices, which deprive milk from many of its natural qualities and benefits. Therefore many essential vitamins and enzymes are lost. Processing milk has altered one of nature’s perfect foods and changed it into something nature did not intend. Because of the abundant health benefits in raw milk, this report will explain why it should be made legal for consumers to buy throughout the United States.
The idea of pasteurizing milk bagan in the 1920s, and later became an aspect of everyday life in the 1950s. Milk that has undergone this process is normally prefered since it is sterilized, therefore lowering the chance of human illness. However, it’s not the 1950s anymore, and the idea of pasteurizing milk has lost its luster for the people that now prefer raw milk. Unlike the milk that most Americans consume, raw milk has not been pasteurized, or quickly heated to a high temperature to kill harmful bacteria. In raw milk, these bacterias haven’t been removed, leaving people at risk. E. Coli, salmonella, and listeria are only some of the bacteria that raw milk carries, all of which can cause sickness, or even death. Common affects of consuming raw milk are diarrhea, stomach cramping, and vomiting, but it's the rare ones: kidney failure,paralysis, and death that causes raw milk to be illegal in half of the states and illegal to carry over state lines in its final form. Nevertheless, people still actively seek out and consume raw milk because they believe its nutritional values to be greater. Controversies surround this topic on whether organic food
Psyche Williams - Forson presents the power of race, class, and food in the American consciousness by analyzing how food such as fried chicken and watermelon can be a symbol of class stratification, inferiority, resistance, and oppression. Fried chicken and watermelon were presented as defining African American foods for the first time post slavery to solidify white supremacy through what can historically be defined as a coon image. A coon image was an image used in different advertisements to show how a watermelon or fried chicken can be connected directly to a black person. An example of one coon image is an image that depicts several phases of a black person's head and face going from what is a person's head to what was a watermelon. The
The recital took place on Wednesday, April 25, 2018 at 8pm at the Capistrano concert hall. It was a graduate jazz bass recital that was performed by Oscar Aguilar. It consisted of an ensemble of seven people performing different instruments the bass was performed by Oscar Aguilar, then there was Sean Nelson who was on the drum, Elias Lucero on the guitar, Jackson Stafford and a switch with Montana Monce on the piano, Jason Danielson on the trombone, Jack Riley on the tenor/ Alto Sax, and Tom Molina on the trumpet. The musical genre of the recital is jazz. The length of the pieces were both short and long, which consisted of nine upbeat and fun pieces such as: So What by Miles davis, Dexterity by Charlie Parker (arr. Oscar Aguilar), Got me

Watermelons; deeply-rooted fruits growing connected to other products on vines are a popular summertime snack. These treasures are a staple in the Southern way of living as well as throughout pop culture with social media pages going wild for watermelons. Locally, there is a town that has been going wild for watermelons for 37 years with the fruit becoming a symbol for the small-town gem. Russellville, AL, just 30 miles south of the Tennessee River, is home of the Franklin County Watermelon Festival a two-day extravaganza held the third weekend of August yearly.
The gorgeousness of summertime is best enjoyed with a juicy watermelon. Nothing can quite capture the spirit of this season. It is a time when most cherish every hour and every day. The season comes and goes faster then any other, and a new school year is followed shortly after. In this poem, the author uses adjectives to explain the significance of both the season and the luscious fruit that is being enjoyed. In a less clear way, the happiness associated with being young is also expressed. Clearly the focus is on the carefree nature of the season itself. “During that summer, when unicorns were still possible.” It is a known fact that unicorns do not exist. In referring to when they used to be possible, the author is mentioning an earlier point in life when the imagination was most important. The watermelon that was being eaten is usually served during barbecues during the summer months. This is a common theme in describing good times. Most people have a childhood filled with at least some good memories. In my experience, sitting out in the sun with some ripe watermelon and plenty of family was a common thing. Although there will be many more good times to come, the fond memories I have during those “first” summers will never be forgotten .

In seedless watermelons, rudimentary seed structures form but remain small, soft, white, tasteless and undeveloped tiny seed coats that are eaten virtually undetected along with the flesh of the melon. Seed production for these seedless types is an extremely labor intensive process that makes the seeds relatively expensive. Because germination of these types is often less vigorous than normal types, it is recommended that they be started in peat pots or other transplantable containers. Here the germinating conditions can be closely controlled. Once transplanted, cultivation is similar to that for regular watermelons.
