Throughout history, humans have found countless new ways to ferment the resources available to them. The benefits of this process can be encountered all around us in the world. Many don’t know the coffee they drink in the morning and the yogurt they bought from the grocery store experienced fermentation of some sort. Fermentation is the partial degradation of sugars without the use of oxygen, causing it to be called anaerobic respiration. The fermentation of yogurt proves to be a process I deeply admire, as I love the taste it produces. Being a dairy product, yogurt comes from the fermentation of bacteria known as “yogurt cultures.” There are two types of yogurt that come from this process. There is the set type of yogurt that contains fruit at the bottom of the mixture and the swiss type that has fruit blended into it. Regardless of the type, yogurt always contains a delicious taste that is driven by lactic acid fermentation. …show more content…
These two cultures are used to ferment lactose, or milk sugar, in order to produce lactic acid. As the lactic acid continues to increase, the pH levels in the yogurt lower. This helps cause milk clots that begin to form the yogurt. The fat that comes in yogurt comes from the amount of milk utilized in the mixture. Thus, the more milk added in the more fatty the product will be. As previously stated, the metabolic pathway of yogurt is lactic acid fermentation. This pathway is where glucose or other six carbon molecules are broken down and converted into cellular energy. The starting point for this remains glycolysis, where glucose is split into pyruvate, followed by the reduction of pyruvate to lactate. The lactic acid formed during this process allows the changes to
One of the most primitive actions known is the consumption of lactose, (milk), from the mother after birth. Mammals have an innate predisposition towards this consumption, as it is their main source of energy. Most mammals lose the ability to digest lactose shortly after their birth. The ability to digest lactose is determined by the presence of an enzyme called lactase, which is found in the lining of the small intestine. An enzyme is a small molecule or group of molecules that act as a catalyst (catalyst being defined as a molecule that binds to the original reactant and lowers the amount of energy needed to break apart the original molecule to obtain energy) in breaking apart the lactose molecule. In mammals, the lactase enzyme is present
Milk Milk is an almost complete food. It consists of proteins (mainly casein), salts, fat and milk sugar, or lactose. It also contains vitamins A, C, D, certain B vitamins, and small amounts of others. Factors That May Affect The Reaction Ø The concentration of Rennin Ø
TCBY has been a frozen treats product innovator from the day its first shop opened in Little Rock, Arkansas in 1981. The great-tasting, low-fat frozen yogurt concept received an enthusiastic response from an increasingly health-conscious public. Its trendy new product propelled the company to the forefront of franchising, and was the ‘first in a long line of ground-breaking menu items that anticipated consumer preferences and continually refreshed the TCBY concept’ (Conlin 2001, p. 133). But TCBY products are just one of the reasons that thousands of operators have concluded that a TCBY franchise is the preferred opportunity in branded frozen treats, and a dynamic partner in any co-branded concept. However, TCBY is facing a lot of problems, both internal and external, during the difficult period from the late 1980s to the early 1990s, especially the problem with its franchising system. The purpose of this report is to provide a comprehensive situation analysis of TCBY, with special reference to its franchising system, and identify several concerned issues of TCBY and its franchisees, and how these issues have negatively affected the relationship between them. Furthermore, this report also provides three recommendations in the attempt to diminish these concerned issues and better maintain the relationship between TCBY and its franchisees, and most importantly, help TCBY to increase the company’s performance and achieve their strategic goals in the next few years.
LI was first recognized in the 1960s when researchers found black children responding unfavorably to milk in their diets (Harrison 812). Research led to the discovery that lactose, the major sugar in milk and related dairy products, was undigestible in some people because they were missing the enzyme lactase. Lactase breaks down lactose into its component monosaccharide sugars, glucose and galactose. In people missing lactase, lactose passes undigested through the small intestine. In some people, the undigested lactose passes through the remainder of their systems with no ill effects. In others, however, the undigested lactose becomes viscous and ferments in the colon (Englert and Guillory 903). The thickness of the liquid and the fermentation cause painful cramping, gas and sometimes diarrhea. Besides not being able to digest lactose, these people suffer from malabsorption, which causes them to receive little or none of milk's nutrients (Houts 110).1
The bacteria ferment lactose, then cause the pH of the media agar to drop and resultant change in pH is detected by neutral red. The neutral red is absorbed by the lactose fermenting bacteria and appear as bright pink to red on the MacConkey agar. The strong lactose fermenting bacteria produce resulting in a pink halo in medium while the weaker growing on MacConkey agar will still appear pink to red but will not be surrounded by a pink halo in the surrounding medium. The gram-negative bacteria that grow but do not ferment lactose appear as colourless on MacConkey agar plate. The agar surrounding the bacteria remains transparent. Lactose can be replaced in the medium by other sugars and the abilities of gram-negative bacteria to ferment these replacement sugars is detectable in the same way as lactose
By taking a Carbon Dioxide, rich substance and mixing it with a yeast, solution fermentation will occur, and then it could be determined if it is a good energy-producer. In this study glacatose, sucrose, glycine, glucose, and water were used to indicate how fast fermentation occurred. The overall result shows that monosaccharides in particular galactose and glucose were the best energy source for a cell.
Microorganism is a living thing that cannot be seen by naked eye and is so small in size. Microorganism usually can be seen through microscope because microscope have the ability to see small thing using various magnification. The examples of microorganism are bacteria, fungi, protozoa, algae and virus. Among all of the microorganisms, bacteria have the greatest advantages in preserving food and beverages. Bacteria are generally harmless but can produce enzymes that can alter the structure the food. In extreme cases, bacteria can secrete toxic substances that can cause the food to spoil.
Investigating the Effect of Temperature on the Fermentation of Yeast To fully investigate the effect of temperature on the rate of fermentation of yeast Background Information Yeast is a single-cell fungus, occurring in the soil and on plants, commonly used in the baking and alcohol industries. Every living thing requires energy to survive and through respiration, glucose is converted into energy. There are two types of respiration available to living cells are: 1.
The “My Choice” frozen yogurt company is a speciality shop for frozen yoghurt. In the frozen dessert industry, frozen yogurt is a new popular dessert since ice cream. Although frozen yogurt businesses have developed greatly in the past few years in New Zealand, and are going strong in the future. Frozen dessert category is characterized by high demand in New Zealand and Australia. New Zealanders love their ice cream products than other country people.
“Fermentation occurs in fruits, bacteria, yeasts, fungi, as well as in mammalian muscle”(Biology Online, 2008, p. xx-xx) . “Yeasts were discovered to have connection with fermentation as observed by the French chemist, Louis Pasteur” (Biology Online, 2008, p. xx-xx). “Pasteur originally defined fermentation as respiration without air” (Biology Online, 2008, p. xx-xx). “However, fermentation does not have to always occur in anaerobic condition” (Biology Online, 2008, p. xx-xx). “Yeasts still prefer to undergo fermentation to process organic compounds and generate ATP even in the presence of oxygen” (Biology Online, 2008, p. xx-xx). “However, in mammalian muscles, they turn from oxidative phosphorylation (of cellular respiration) to fermentation when oxygen supply becomes limited, especially during a strenuous activity such as intensive exercising” (Biology Online, 2008, p. xx-xx).
The denaturation occurs when soy milk is being heated. The proteins in soy milk are denatured and when the denatured proteins meet the gypsum powder mixture, coagulation slowly proceed. The gypsum powder in the mixture reacts with water to form solid gypsum slowly. It changes from liquid state to solid state and acts as a good coagulant that helps the hot soy milk to coagulate into semi solid form. After some time for precipitation, tofu pudding is formed.
Dietary Fiber fermentability also varies due to a high diversity in both physical structure and the chemicals bound between monomers found in the digestive tract (Bindelle et al., 2007). Dietary Fiber that escapes digestion in the upper part of the gastro-intestinal tract, is potentially available for bacterial fermentation in the large intestine. The anaerobic bacteria concentration in the pig gastro-intestinal tract passes thus into the stomach and the small intestine to the large intestine. The intestinal bacteria hydrolyse the polysaccharides composing the Dietary Fiber and metabolise their constituent sugars through a series of anaerobic energy-yielding reactions leading to the production of ATP which is essential for bacteria basal and growth metabolism (Bindelle and Buldgen,

After researching more about prevalent yogurt categories, Greek yogurt dominates the yogurt market. Studying and understanding the general use of yogurt, its significant category brands, brand advertising strategies, and the industry trends help to understand the reason Greek yogurt is the top selling yogurt. Many individuals consume yogurt for many different reasons. Michael Neuwrith, senior director of public relations at Dannon, said that the average American consumes about 1 yogurt per week. Knowing this, one must also know that there are many different types of yogurt today depending on what one is looking for.
Most brands run in the one hundred to one hundred and fifty calorie range. And then there's the sugar content. A typical six or eight ounce cup of yogurt contains anywhere from 15 to 22 grams of sugar. This is the same sugar content found in a bowl of ice cream and even some candy bars.
