Essay On Fruit Juice

The purpose of this lab was to test different substances using various procedures to see what biomolecules were present and ultimately find out what restaurant Anna Lyza had eaten at before she died. For the first control test, we used vegetable oil to test for lipids. So, if the solution does not contain lipids, it does not become translucent when placed onto a paper bag square and held up to a light. So, it is a negative result. However, in the presence of lipids, the solution will become translucent when placed onto a paper bag square and held up to a light. Therefore in this case, the result is positive. On the other hand, we used albumin egg to test for proteins in another control test. If the solution does not contain proteins, it will not experience any color change and so it is a negative result. When there are proteins existing in the solution, it will turn bluish/purplish and for this reason it is a positive result. Furthermore in the third control test, we used dextrose to test for simple carbohydrates such as glucose. If the solution does not contain simple carbohydrates, it will not undergo any color change and will remain a blue color. So, it is a negative result in this circumstance. If there are simple carbohydrates present in the solution, the solution will turn reddish and so the result is positive. For the last control test, we used starch solution to test

Purpose/Hypothesis: The purpose of this experiment is to use both cabbage juice and pH paper to determine the pH of household items. This way, we can tell which products are basic and which one are acidic. If we use cabbage juice as an universal pH indicator by comparing it to pH paper then pH determined by the cabbage juice will be unstable because by using cabbage juice, it can be different depending on how diluted it is.

Consumption of fruits and vegetables at or over the recommended five servings per day is associated with a decreased risk of heart attack and stroke. Greater consumption of fruits is also associated with a lower risk of type 2 diabetes.

Although Jamba Juice demands a large amount of agricultural commodities to help produce the healthy and organic smoothies, these commodities are limited. There are not other substitutes can replace these agricultural commodities to make smoothies as healthy as the organic raw materials. Hence, this gives the suppliers the opportunities to raise the price or decrease the quality of the agricultural commodities.

The book “The Sweeter The Juice” is part autobiography and part family narrative of Shirlee Taylor Haizlip and her extended family. Her family narrative is composed of stories about the lineage of her mother and father; these stories were a product of extensive research into historical documents and accounts of relatives passed down from generation to generations. Haizlip intertwines her family stories with historical figures and events allowing for the audience to be able to relate certain characters to the timeline of the history of the United States. As well, she provides personal accounts of her experiences while researching for her family’s past: where she traveled,

7. Using the slider on the right hand side, add NaOH to the HCl in the Erlenmeyer flask (This action is known as titrate). Add the indicator until the color of the indicator turns a light shade of pink.

Table 2: Consists of color extract taken from a red cabbage for a natural indicator. The pH reading that was measured by using the pH meter and the result of the pH reading to determine whether the solution was acidic or basic.

The filter paper was then observed to see if it changed blue or not, in order to see if the bacteria produced cytochrome c oxidase. The final test used in the experiment was an API test. To begin the API test, a solution with bacteria and 5 mL of sterile saline, had to be made with a turbidity the same as the McFarland No. 3 (BaSO4) standard. This was done by adding loopfuls of bacteria to the saline solution, mixing the solution on the vortex, and then comparing the turbidity to the McFarland No. 3 standard, until the tubes were both at the same cloudiness. This created solution was then used in the API test by adding specified amounts to each of the microtubes on the API strip. For each of the microtubes whose names were not underlined or boxed, the tubes were filled to where the microtubes met the capsule. In the microtubes whose names were underlined, the microtubes were slightly underfilled, and then the capsule was filled with mineral oil in order to create and anaerobic environment. The last of the microbes were the ones whose names were boxed. In each of these the microtube and the capsule were filled all the way up with the bacteria. The API test strip was then placed in the 37°C incubator for 20 hours. After this time, observations were made about each of the different microtubes based on a given summary of results chart for the API test. A select number of microtubes had

Fruit and vegetables provide vitamins, minerals, dietary fibre and many phytonutrients (nutrients naturally present in plants) that help your body stay healthy. Since fruit and vegetables are low in kilojoules (energy) relative to many other foods, including them every day can help prevent excessive weight gain. They may also help protect against chronic diseases such as heart

In the ethnographic text, Fresh Fruit, Broken Bodies, by Seth Holmes, Holmes describes his experience on enduring the living and working conditions of migrant workers. Seth Holmes’ social positions and identities helped bring the ethnography forward by showcasing the stories of Triqui migrant workers and how they suffer in everyday life because of the cycle of suffering. On the other hand, Holmes risks credibility and validity as the ethnographic text is taken from his point of view as a white man rather than a Triqui worker’s. As the author of the ethnographic text, Seth Holmes takes an in-depth look inside the lives of the Triqui workers and the problems they encounter in the face of racism and the social, political, and economic

The USDA classifies the different food groups as fruits, vegetables, grains, proteins, dairy, and oils. Each of these food groups has specific serving recommendations and other considerations regarding food choices and consumption. In regards to vegetables, intake should vary among the subgroups--dark green, red and orange, legumes, starchy, and other. Servings per day should be 2 ½ - 3, depending on personal needs. Having a variety of vegetables, as close to the whole form as possible, offers an abundance of essential nutrients such as Vitamin C, A, K, E, B6, fiber, potassium, niacin, just to name a few. Fruits offer similar nutrients as vegetables and should be consumed daily, ideally two servings a day. Fruit juice can count as a serving of fruit as long as it is 100% fruit juice. However, the benefit of fiber is lacking from this source and added sugar may be present. Ideally, it should have no added sugar if choosing it as a serving of fruit (USDA, 2016).

19. Stir the solution with a toothpick and observe any changes. Measure the pH of the new solution and record into Table 2.

Vegetables have more minerals, vitamins, and even more anti-cancer properties than fruit. The difference between the two food groups is the calorie content. In general, vegetables have fewer calories than fruit.

Determination of the bacteria being a lactose fermenter or non fermenter is done through the growth on the MacConkey agar. Knowing this allow for the student to perform the necessary tests to determine which lactose fermenter was present in the sample. The Indole test allows for the determination of whether the unknown bacteria is Escherichia coli because this genus and speices is the only lactose fermenter that will produce a positive result here. Moving onto the Methyl red test this indicates glucose fermentation, more specifically microbes that produce mixture of acids as a result of fermentation. The Voges-proskauer tests for glucose fermentation, specifically organisms whose acid is converted to acetoin. The Citrate test differentiates an organism’s ability to use citrate as its only carbon source. The urea broth culture detects the enzyme urease, which allows break down of urea producing acid, which causes a noticeable change in color. The final test is the motility test to determine if the bacteria has the capacity of movement beyond the point of

The pertaining research involves the electrolytes in drinks. “Electrolyte” will be defined and its description of what they do, what they are, and how they help people will be further explained. The intention is to establish the efficiency of sports drinks and orange juice and then compare them. The pros and cons of both the orange juice and sports drinks will be elucidated through the research. Other drinks consumed after exercise will also be researched and their efficiency will be explained.
