Next, using a graduated cylinder, tap water (10 mL) was added to each vial containing the culture medium. Upon addition of water, white culture medium turned blue. Additional amounts of tap water were added to each vial to provide more moisture. Next, three grains of yeast were added to each of the four vials. The vials were capped.…
Name: Sebastian Sak Lab Partners: Tim Gronet TA: Feifei Xu Determining Molar Enthalpy of Dehydration of Sodium Acetate Trihydrate Purpose: In this lab, two solid substances, sodium acetate and sodium acetate trihydrate, will be analyzed for the heat of solution for both processes. This allowed the calculation of the molar enthalpy of dehydration of sodium acetate trihydrate. Calorimetry was used to experimentally determine the heat of solution for both reactions.…
Known as the human species oldest recreational drug, Ethanol is a colorless, flammable liquid, with a distinct smell, and burns with a blue flame. It has the chemical formula of CH3CH2OH (it's molecular formula) or C2H6O (it's empirical formula), that can also be abbreviated using chemistry notation as EtOH. It has a melting point at -173.2°F , and a boiling point at 173.1°F. Ethanol has many handy uses around the world, in many different places.…
The process of producing maple syrup from maple trees is actually quite easy. The first thing that we will have to do at the start of production is find a sugar maple tree to tap. When a maple tree is found a hole will be drilled into the tree and then a spile will be put into the hole. A spile is a spout that allows the sap to flow out of the tree and into some sort of container that will hold the sap. A single tap in one of the sugar maple trees will produce about 10 gallons of sap, which will boil down to about 1 quart of maple syrup (Saupe 2009).…
interest in purchasing Cuba had begun long before 1898. Following the Ten Years War, American sugar interests bought up large tracts of land in Cuba. Alterations in the U.S. sugar tariff favoring home-grown beet sugar helped foment the rekindling of revolutionary fervor in 1895. By that time the U.S. had spent more than fifty thousand dollars in Cuba and trade, mainly in sugar, was worth twice that much. War was becoming intense and had been growing in the United States, despite President Clevelands proclamation of nuterality on June 12, 1895.…
Fairy Floss was such a hit and everybody wanted a taste! Who wouldn't when its original name is Fairy Floss? Cotton candy was such a hit in the late 1800s and early 1900s. The way cotton candy melts in your mouth is such an exhilarating taste that could make anybody go wild without it! The invention of cotton candy revolutionized the world, making it such a better place!…
The current law in America states that a person who is the age of twenty-one or older is legally allowed to consume alcohol. There are many arguments whether this law should be changed to a lower age, preferably eighteen, or raised to an age somewhere around twenty-five. When the hardcore facts concerning this substance are thoroughly examined and thought over, one would see there is only one answer to this dispute. The United States has many problems concerning alcohol and younger people in today’s society; therefore, the legal drinking age must be raised.…
Part B Two test tubes were labeled, one with “yeast” and the other with “water”. 1 ml of yeast suspension and 4 ml of distilled water was added to the “yeast’ labeled tube. 5 ml of distilled water was added to the “water” tube. 5 ml of sucrose solution was added to each test tube and stirred.…
Each tube was labelled from one to six. 15 mL of solution with 10% concentration were added in the respective tube for starch, lactose, sucrose, glucose, fructose, and distilled water. 15 mL of distilled water and 15 mL 10% yeast suspension were poured to each fermentation tube as seen in Figure 1. All the mixtures were gently shaken at the same time without spilling the mixtures.…
Agriculture has historically been of strategic importance to the Cuban economy due to itsmultiplier effect on other sectors of the economy, its ability to generate export income and increase gross national product, create employment, and contribute to food production. Cuba’s agricultural sector has been characterized by a high level of specialization in sugarcane production for export purposes. This heavy focus on sugarcane production had resulted in a severe lack of domestic food diversity and production, thus leading to a strong dependence on food imports. Together, these circumstances led to Cuba being extremely vulnerable to food security and economic crisis. Throughout most of the 20th century, Cuban sugarcane exports accounted for a substantial portion of the total value of goods produced and over 75% of the value of Cuban exports.…
Sugarcane Press mud Sugarcane Press mud - Sugarcane press mud is the residue of the filtration of sugarcane juice. The clarification process separates the juice into a clear juice that rises to the top and goes to manufacture, and a mud that collects at the bottom. The mud is then filtered to separate the suspended matter, which includes insoluble salts and fine bagasse. This industrial waste is mostly used as soil conditioner, soil fertilizer and for wax production.

The importance of enzymes in modern food biotechnology Introduction: The use of enzymes outside their natural environment in food technology gets more and more important. Although the application of enzymes as food additives or in processing raw materials has been used since a long time, it gets more and more popular and also crucial for many processes. Especially because enzymes are labelled with the GRAS (generally recognized as safe) tag, they are very desirable for industries and also consumers to use to convert raw materials into end products. Therefore, many chemicals, which could be harmful to the human body are replaced by enzymes or are tried to be replaced through the discovery of adequate enzymes.…
Results Unit 800 produces ethylene and acetic acid through the partial oxidation of ethane. Ethylene, the most abundant product from the unit, is partitioned such that half of the product is used as a feed source for Unit 600 and the other half is sold on the market. Ethylene purity must reach at least 99.5% to be sold as reagent grade. The second desired product, acetic acid, is also sold on the market, at 99% purity. Unit 800 consists of a fired heater to preheat the reactants, an isothermal reactor to produce ethylene and acetic acid, a series of heat exchangers to cool the product, and a separation train to distill products to an economically sustainable purity.…
Sugarcane (Saccharumofficinarum L.) is one of the most important mono cotyledon crop crops widely cultivated in tropical and subtropical regions which belongs to the family of Poaceae. It is an octaploid crop with a chromosome number of 2n = 8x = 80. Being highly cross-pollinated in nature, this crop requires specific, hot and humid climate for flowering (Gill et al., 2006). The sugar from the sugarcane accounts for about 70% of the worlds’ total sugar production (Comstock and Miller 2004)…
CHAPTER 4 RESULTS AND DISCUSSION 4.1 Incomplete Carbon Glucose Preparation for sulfonated solid acid catalyst must undergo a process which is called carbonization or pyrolysis. Glucose is natural organic compounds had been used as starting raw material because it is cheap and less toxic. Carbonization is an important step before the sulfonation process because it will form amorphous carbon composed of small carbon sheets [B] and produced sites for sulfonic group to be attached or inserted into the small of non-graphitic carbon during sulfonation.…
