Varying Concentration of Rennin and Its Effect on the Goagulation Time of Milk Scientific Knowledge Enzymes Enzymes are large molecules, which are protein in nature. They are biological catalysts that speed up chemical reactions in the body. They operate by a "lock and key" method. The Enzyme has a certain "lock" (active site) that only a specified substrates "key" will fit into. Enzyme action Rennin A proteolytic enzyme that speeds up the coagulation of milk. It is usually found in the tissues of a calves fourth stomach. Its purpose is to coagulate the milk in young animals so that the proteins have time to be extracted, rather than flowing straight through the digestive system. This particular enzyme catalyses the conversion of the protein in milk (caseinogen) into paracasein. This forms a thick curd in the stomach meaning the milk can be exposed to Rennin for a greater period of time. 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 The concentration of Milk Ø The volume of Rennin Ø The volume of Milk Ø The temperature of the reaction Ø Agitation The factor I have chosen to explore is the concentration of Rennin because I believe that varying the temperature of the reaction is very hard to control and therefore may be inaccurate and agitation is a very simple investigation. I have a prediction for the investigation concerning the concentration of Rennin, another reason I chose this factor. Prediction I predict that as the concentration of rennin increases the rate of reaction will increase. I believe this to be true because if there are an increased number of enzymes, more milk particles will be broken up at any one time into the substance, which coagulates the milk,

    The Shipping Manager’s activities required a different approach. He used coordination through formal hierarchy. The Shipping Manager assigned the Team Leader tasks that required more supervision and resources. He gave an order to the Team Leader who divided it among his Pullers. The Pullers would enter the tunnel, assemble the order from the various coolers and send it down the track to the awaiting loaders. The Loaders would remove their assigned color-coded stacks and put them in the appropriate trucks for delivery. This process did not require special training but it did require more direction from the Supervisors than the warehouse functions.

    The affects of pH, temperature, and salt concentration on the enzyme lactase were all expected to have an effect on enzymatic activity, compared to an untreated 25oC control. The reactions incubated at 37oC were hypothesized to increase the enzymatic activity, because it is normal human body temperature. This hypothesis was supported by the results. The reaction incubated to 60oC was expected to decrease the enzymatic activity, because it is much higher than normal body temperature, however this hypothesis was not supported. When incubated to 0oC, the reaction rate was hypothesized to decrease, and according to the results the hypothesis was supported. Both in low and high pH, the reaction rate was hypothesized to decrease, which was also supported by the results. Lastly, the reaction rate was hypothesized to decrease in a higher salt concentration, which was also supported by the results.

  • The Country's Best Yogurt (Tcby) Case Study

    1779 Words  | 4 Pages

    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.

    ...at keep organisms alive. “Proteins are the most structurally sophisticated molecules known” (Campbell, 1999) which is reason enough to study them. The techniques we learned in this lab form a basis from which a detailed study of proteins is possible. Following our procedure we were successfully able to set up a quantifying assay to determine the amount of protein within a milk sample, although our yield percentage was rather low. However, errors in this lab (in the form of a low yield percentage) may have an origin from our last lab. In the process of extracting proteins from the milk sample, we may have inadvertently lost some of the protein through erroneous measurements, or perhaps through poor handling of either ammonium sulfate or the dialysis tubing. While not sufficient enough (at this point) to invalidate our results, they do explain the major difference between the expected and the actual amount of protein extracted.

    For the second experiment we predicted that pH 7 would be optimal for lactase function. For the third experiment we predicted that 25°C with milk and lactase would contain the highest glucose concentration, this is because they are close to the natural environment of the lactase in which enzymes function.

  • Legalizing the Selling of Unpasteurized Milk

    1177 Words  | 3 Pages

    When produced from a grass fed, healthy, clean animal, unpasteurized milk is a completely safe alternative to pasteurized milk. Raw milk has not been pasteurized or homogenized, it has more nutritional value considering it has not been heated to kill of pathogens (Imus). Raw milk is only unsafe when it comes from overproduced factory cattle. These cattle are in the wrong conditions for healthy milk production (“The Industrial Milk Factory”). It should be legal to sell unpasteurized milk in the local community. The buying, selling, and distribution of pasteurized milk would help boost the local economy and it would also help the local citizens make ends meet. It is much healthier and safer to know where your milk is coming from, rather than to buy it from a larger chain store.

  • Infant Formula: Good, Bad or Innocuous

    1685 Words  | 4 Pages

    Throughout history there has been a need for alternative feeding methods for infants. Whether because of an issue with the mother’s milk supply or because of death of the mother, there have always been children that required the use of something other than their own mother’s milk. In more recent history, alternative feeding has also been used as a convenience. Prior to the development of infant formula in 1865, animal milk and wet nurses were used to accomplish the feeding of orphaned infants or others whose mothers could not, or chose not to, breast feed. Between 1950 and 1970 the breast feeding rate fell dramatically. Some studies suggest that more that 75 percent of American infants born during that time were formula fed. As the rates of diabetes, obesity and other health issues continue to increase researchers are looking at how individuals are feeding their infants and what effects the large amounts of high calorie “breast-milk substitute” may be having. Infant formula is being considered as one of the contributors to the growing health crisis in America. American mothers may be inadvertently predisposing their children to a lifetime of health issues by choosing not to breast feed.

    The Effects of Temperature on the Rate of Clotting Milk and Rennet Introduction ------------ The following experiment investigates the effects of different temperatures on a mixture of rennet and whole milk. On having the choice between testing the mixtures reactions at various temperatures, or testing the mixture with various amounts of concentration of rennet, my partner and I decided upon the first option. We made this decision as we felt it would be valuable to our scientific knowledge if we had a better understanding of how different temperatures can effect the behaviour of an enzyme, such as Rennin, which is also known as Chymosin. Our scientific knowledge tells us that enzymes work most efficiently at specific temperatures, and this experiment helps us to discover exactly which temperatures they are.
