While the particular proposition name of the stabilizer is not presented in the food label. The stabilizer could be derived from carrageenan that functions as an emulsifier in the take out reaping. Below describe the general functions o f the plant originated stabilizer utilize in the take of UHT take out. exit 2(a) Nutritional wellness ClaimIn the content of nutritional and health claim for the Dutch Lady UHT Full cream take out, no nutritional and health claim in identifiable from the pile of the UHT Milk.Topic 2(b) Enrichment FortificationAccording to the Dutch Lady Malaysia website, nutrient such as protein, Vitamin B2 and calcium ar macrocosm enriched into the UHT Full cream draw during the take out production. The purpose for enrichment of the milk is to increase the nutritional value that patron in reproduction of body tissue that is essential to the growth and development. Besides, enrichment of calcium and vitamin B2 in milk would help to improve the bones development as hale as to increase the facilitation of energy release. By definition, enrichment is mathematical operation w present food manufacturer replenish the nutrient that were lost during the performanceing. For the Dutch lady UHT milk, the factor that contri thoes to the enrichment of nutrient is extremely influence by two unit of operation in the milk production (1) Ultra richly temperature rescue technique that crush heat sensitive nutrient such as vitamin B2 and protein and (2) Recombination/ Reconstitution process that habituate milk solid and milk powder as main ingredient. Recombined milk is a type of milk emulsion produce by means of the combination of milk powder, milk solids, milk fat water (Walstra, Wouters and Geurts, 2006). Because the milk solid and milk powder is extracted from the raw milk by the milk product manufacturer, nutrient that atomic number 18 water soluble such as vitamin B and mineral be beingness separate from the milk solid leading to the needs of enrichment during the production of recombined milk. Besides, the enrichment of nutrient in milk is also needed to win the requirement set by the Food regulatory body such as Ministry of health and FDA.Topic 3(a) Factors i nfluencing the cut outslope of foodDutch Lady UHT full cream milk is a product which chthonicgoes Ultra-High Temperature (UHT) preservation technique that be being package into an infertile packaging that be made out of paperboard, polythene and aluminum foil that have the properties against pH, oxygen, joyous and microbial deterioration. With such, the factor that influences the deterioration of UHT Milk is mainly contributed by the corporal stress toward the packaging that would cause a breakage in the packaging. In addition, the breakages caused by physical stress would increases the opportunity toward additional biological and physical deterioration factor such as changes in color and flavor causes by the exposure to light, oxidative rancidity through exposure to oxygen and contamination by food-poisoning microorganisms. Moreover, the utilization and the source of UHT milk packaging by end-user also encourage the deterioration of the milk. Lastly, contaminated packagi ng and machinery in the product line could contribute to the food deterioration. Below describe the factor influencing the deterioration of Dutch lady UHT milk in the packaging as well post-usage deterioration.Physical factorPhysical breed Unprofessional handling and improper storage condition are the major contribution to the deterioration of the aseptic packaging of the milk cartonful. With source of the milk carton that is causes by the mechanical stress, it publish the milk toward deterioration such as oxidation and light inducted color changes that are cause the food undesirable to consume. Besides, the fountain of the milk carton causes the infestation and attraction of rodent that is natur totall(a)yy vector that carries harmful microorganism.Oxygen With the opening of the aseptic packaging causes by physical stress and the usage of UHT milk by end-user. Both expose the UHT milk toward oxygen which encourages the oxidative rancidity of milk lipids that leads to the wre akation of undesirable aroma. In addition, the expose of oxygen also provide a suitable condition for the microbial growthLight The exposure of UHT milk toward cheer bottom of the inning cause the milk to lose its nutritional properties through the disruption of vitamin B2. Moreover, milk that are exposes to sunlight also cause the milk to develop undesirable burned flavor that are collect to the light inductive oxidation of fats and causes the changes in the structure of whey protein.Biological factor Growth and Activities of Microorganism With opening of the packaging cause by physical stress and by consumer, this increase the opportunity of contamination by microorganism that is capable to cause degradation of protein, carbohydrates and fats that deteriorate the quality of the milk. Besides, foul aromas that are being positive by these spoilage microorganisms are deteriorate the quality of the milk. Moreover, other than deterioration that are causes during storage and by c onsumer, deterioration of UHT milk product also laughingstock be contributed by machinery used in the production line of the UHT milk such as the seal in the homogenizer as well as the convey supplied to the aseptic packing unit (Tamime, 2009). In addition, the faulty seams and pinholes in the aseptic packaging box carton are major source of spoilage bacteria in the UHT milk that contribute the deterioration of the food product (Varnam Sutherland, 2001).Topic 3 (b) Principle of food preservation method usedBased on the information given in the Dutch lady Malaysia website and the packaging, the principle of food preservation method being applied into the UHT full cream milk is aseptic bear on with the purpose to contact commercial antisepsis. sterile touch is physical preservation methods that involve the utilization of heat to achieve sterility. The purpose of utilizing heat preservation method in the production of UHT Milk is to increase the keeping quality and the shelf l ife of the milk product. In addition, the utilization of heat word helps to center both the spoilage and pathogenic microbial community and their spore such as mycobacterium tuberculosis, salmonella species, staphylococcus aureus, etc. Besides, heat preservation treatment help to debar enzymatic activity that is derived natively from milk as well as to limit the autoxidation that causes the chemical deterioration of milk lipids (Walstra, Wouters and Geurts, 2006).Commercial sterility in the context of food manufacturing is define as the degree of sterilization that destroy all pathogenic and toxin forming microorganism that are capable to causes spoilage in food under customary handling and storage condition(Vaclavik and Christian, 2008). In the production of Dutch lady UHT Full cream milk, commercial sterility is achieve through aseptic processing which involve the usage of thermal processing in the form of Ultra senior high temperature(UHT) preservation technique determinee d by aseptic packaging technique.The combination of UHT treatment joined with aseptic packaging made a fundamental improvement in term of the bacteriological safety. Moreover, antiseptic processing improve the shelf life of the dairy product from typical 1-2 weeks of the refrigerated pasteurized product to longer shelf life ranging from 6-9 months without the need of refrigeration as well as the addition of food additive to increase its shelf life. Besides, the shelf life stability of the UHT Milk product that are contributed by the aseptic packaging benefits countries where environmental temperature is high as well as the limitation of refrigeration. (Tewari and Juneja, 2007)Topic 4 Unit of Operation in food productionThe units of operation involved in the production of Dutch Lady UHT Full cream milk are(1) Recombination process, (2) Ultra High Temperature process, (3) Homogenization process and (4) unfertile packagingRecombination process A recombined milk product is produce t hrough a combination of milk fat and milk solids-nonfat with or without water to re-establish the restency of natural milk. The recombination process of the milk start with the dispersion of skim milk powder in the water with a temperature ranging between 40 to 50 C. The milk powder is being fed into the water through the usage of hopper with care taken to subjugate any in-cooperation of air. There are various method used to in cooperated the powder into the water, where pre emptying the milk powder in a dry room with dust removal system is commonly applied in the recombination process. After the in-cooperation of milk powder with water, the reconstituted milk is unexpended for minimum 15 to 20 proceedings of hydration with the purpose of minimizing the powdery and chalky mouth feel. In some milk product manufacturer, the reconstituted milk is held long at 4 C prior to further processing to ensure complete hydration. Upon the completion of hydration process, the reconstituted milk is exaltation for filtration to separate out any undissolved milk powder particle. The reconstituted milk is then left for vacuum de-aeration for 20 minutes to remove occluded air that are commonly lay out in the milk powder with the purpose to prevent the fouling of heat exchanger and excessive oxidation. Lastly, the reconstituted milk is heated to 60 to 65 C with the in-cooperation of liquid milk fat or anhydrous milk fat do a course emulsion through virtuous stirring in a static social (USDEC, 2005).Ultra High Temperature The combination of UHT processing together with aseptic packaging in milk was introduced to achieve a shelf stable product, at the same time minimizing chemical change as compared to the in-container disinfect milk. There are two type of oestrus method involved in the UHT process luff indirect heating. In direct heating, UHT process is achieve by mixing superheated steam with milk. While in-direct heating achieve UHT through transferring heat from pl ate heat exchanger(PHE) across a partition between the milk and the heating medium either through steam or hot water (Mehta, 1980 Burton,1988). The Ultra high temperature processing involve heating the milk in a continuous process system to a relatively high temperature ranging around 135 degree Celsius with a minimum two second of safekeeping time followed by a rapid cooling. Since the sterilization and cooling process of the flowing liquid-milk in the UHT process is relatively adjacent, the longtime heat penetration problem derived from the in-container sterilization is avoided. Through the rapid heat transfer technique utilize in the UHT process, undesirable changes in taste and nutritional quality of the milk is minimized. (Tewari and Juneja, 2007) antiseptic Packaging Aseptic packaging is a form of preservation technique involved the f bading of sterile milk product into the sterile container (aseptic tank) in a sterile environment. It is then subsequently sealed through a co ntinuous process that provides a high operational flexibility as well as high stability against microbial contamination (Tewari and Juneja, 2007). Moreover, the application of aseptic packaging allowed the milk to be package into a relatively versatile container that does not require any form of refrigeration condition that can be easily distributed in part of the world where refrigeration is uncommon. The most common aseptic packages used in the UHT milk are the tetrahedral-shaped paperboard cartons exemplified by Tetra Pak that is made out from the laminated roll stock consist a combination of polyethylene, paper, polyethylene, aluminum foil, polyethylene, and a coating of ionomer resin (Potter and Hotchkiss, 1998).Homogenization Homogenization process is a universal set of industrial practice, purpose to stabilize the fat and water emulsions against separation that are causes by the gravitational pull (Bylund, 1995). In composition of the milk and cream, milk lipids are made out of fat globule that varies from 0.1 to 20 m in diameter that have the tendency to gather into clumps which rises due to their relatively brightness density as compared to skim milk. This separation between the milk lipids and milk causes highly visible separated layers that are undesirable and unappealing to consumer. To eliminate the separation of milk, homogenization process is applied in the production of milk to cause the disruption of fat globules in order reduce its size to a smaller one, where the new interface is covered with milk protein predominantly micellar casein. Consequently, help to minimize the creaming properties of the milk as well as the tendency for fat globules to coalesce. Moreover, the purpose of integrating homogenization process in the production of UHT milk is further supported work from Walstra, Wouters and Geurts , where the process help to counteracting the creaming of milk lipids, to improve the stability towards partial alinement as well as to creat e a desirable rheologic properties of the milk (Walstra, Wouters and Geurts, 2006).ReferencesBylund, G.

Ebola was first identified in the Democratic body politic of Congo or which was previously known as congou tea, since it appeared in the town of Yambuku-central Africa in the year 1976 (Draper, 2002).The largest and the most complex Ebola blast since the first outbreak was in 1976, which was experienced by the people of west Africa in march 2014 (World Health Organization, 2014). This particular outbreak has gone through many another(prenominal) cases which have lead to death more than all the previous outbreaks combined (WHO, 2014). Ebola can be classified according to its genetic antigenic characterization (Porrut, 2005).1.2 History of Ebola.Ebola virus was first discovered and experienced in the form of two simultaneous outbreaks, first due to the E.Sudan and the other due to E.Zaire, both these outbreaks happened in congeals close by, in Sudan near the border with the Democratic republic of Congo (Smith, 2005).This virus further bear upon the towns of Nzara and Maridi between June and November 1976 which gave mortality rate as 53% cl of 284 victims which is the characteristic of the Sudan subtype (Smith, 2005).The second outbreak was due to the E.Zaire which occurred in the border of the democratic republic of Congo which is close to Sudan and the Central African Republic between August and November in the same year 1976 (Johnson, 2005). The virus is named later the Ebola River where the virus was first discovered in 1976 (CNN, 2014). The third outbreak occurred between July and October 1979 in the same place attacked by the Sudan virus, but didnt cause great extensive outbreaks like the first two, this virus affected 34 people and killing 22- mortality 65% (Porrut, 2005).1.3 Characteristics of Ebola virus.Among the Filoviridae virus, the two commonly found deadly viruses are the Ebola and the Marburg viruses- This viral family contains viruses with non segmented negative-sense RNA genomes (Geisbert and Jahrling, 2005,). Ebola virus is not harmful unless it fuses its glycoprotein viral with the host cell membrane (Wood-Lewis et al., 2005). There are mainly five types of Ebola viruses identified, which are Ebola Zaire, Ebola Ivory Coast, Ebola Sudan, Ebola Bundibugyo, Ebola Reston and the one which is producing the outbreaks in 2014 was due to the Zaire species (WHO, 2014) Filovirus cell entry is supported by its class I fusion protein or the spike protein GP1, 2 (Volchkov, et al., 2011). There are seven genes in the order 3 leader, nucleoprotein, virion-protein 35, VP40, glycoprotein, VP30, VP24, RNA-dependent RNA polymerase (L)-5 trailer found in the genome (Sanchez et al., 2011).Ebola virus is transmitted to a human via having direct contact with another Ebola victim-here the direct contact includes blood, secretions, organs or other body fluids of the victim and also the surfaces and materials which are contaminated with these fluids (WHO, 2011). Usually the victims of Ebola are septic as long as their blood and body fluid-which includes semen and breast milk is contaminated with the virus (WHO, 2011). Ebola releases number of countless chemicals like cytokines, chemokines and histamines when it infects various types of cells (Smith, 2009).this causes the number of symptoms we can observe to conclude whether the person is a victim of Ebola or not( Smith, 2009).this viruss genome is particularly small and appears as a long lous e l where it resembles a length of thread but it can also be in a U-shaped or in a shape of 6 or even at times circular.( Smith, 2009).1.4 Symptoms of Ebola.Ebola viruses are pathogenic for humans, as they cause specific febrile hemorrhagic disease and these symptoms will be in a flash shown after nearly a week (Baron, 2005) normally the symptom of Ebola includes pyrexia, headache, and abdominal pain. Nausea, fatigue and mostly an ill feeling, but this is what makes diagnosing Ebola difficult, as these symptoms are common for many diseases (Smith, 2009). But to elaborate more, first symptoms of Ebola are sudden fever, muscle pain followed by headache and sore throat along with this the rest of the symptoms are shown which are vomiting, diarrhea, rash and even at times internal and external bleeding is shown (WHO, 2014).1.5 Diagnosing Ebola.It is usually difficult to categorize the Ebola virus and Marburg virus as they both have got similar clinical symptoms here the most common sy mptoms are severe, febrile and acute fever (Feldman et al, 2005). Recently there have been many outbreaks on Ebola in several countries of central Africa and due to these outbreaks there have been different types of field nosology as checkup sophisticated support was required. (Feldman et al., 2003,). For an instance, the two outbreaks of Ebola hemorrhagic fever which took place in Gabon, 1996 resulted in mortality of 66% and 75% respectively in laboratory confirmed patients. (Courbet et al., 1999). Several diagnostic stops for Ebola contagious disease are currently used and have been recently evaluated in patients in the field. (Ksiazek et al., 1999).The different species of Ebola virus see to cause somewhat different clinical syndromes, but its slightly difficult to observe them under perfect conditions, and its very rare that observations like this are done. (Feldman, Geisbert and kawaoka, 2007, p.129)Using the symptoms Ebola can be identified, but before doing so it is inv estigated using so many procedures like Antigen-capture detection tests, Serum neutralization tests, abandon transcriptase polymerase chain reaction (RT-PCR) assay, Electron microscopy, Virus isolation by cell culture and Antibody-capture enzyme-linked immunosorbent assay (ELISA). Handling these can be highly dangerous and can be risky as these can be transmitted through direct contact (WHO, 2014).1.6 Treatment methods for Ebola.Due to its specific morphology, still the drugs and the therapies are not fully evaluated, however it is currently evaluating (WHO, 2014).At the same time Ebola can be prevented to its maximum if we follow infallible preventive techniques like raising the awareness of Ebola transmission, safe burials and social mobilization (WHO, 2014).Different species of Ebola virus causes different symptoms but the opportunities for a good observation of the virus under good condition is very rare (Feldman et al., 2011).The virulence of Ebola virus differs according to the species or strain which attacked the humans as well as non-human order Primates (Sanchez et al., 2011).among the Ebolas genus infection rate of the Zaire Ebola virus and the Sudan Ebola virus rate differs, among these the Zaire Ebola virus has the highest case-fatality rates which is 60-90% (Guenno et al., 2011).lately due to some investigations done which included the observation of some attenuated vesicular stomatitis virus expressing the Ebola virus surface glycoprotein which previously has demonstrated efficiency as a vaccine against Ebola infections in rodents and monkeys (Feldman et al., 2007). It should be highly realized that workers such as doctors, nurses, scientists who work with direct contact with the victim too should be under consecutive care as Ebola is a directly spreading virus (Casillas, 2003).1.7 Conclusion.Moreover to summarize all what is express above we can say that Ebola is not a virus to be put down as it is highly dangerous and very harmful as it can easily spread which causes it to be deadly and also as it can keep rising leading to tragedy deaths. And to recall the past, it is said that Ebola was found in Africa and the name itself implies on the first outbreak which happened near the Ebola River and also there are five main types of Ebola viruses but among them the E.Zaire and the E.Sudan are the commonly found ones. Ebola is a class 4 pathogen belong to the family Filoviridae as it causes severe hemorrhagic fever and various symptoms and this is currently incurable as there are no specific treatments or drugs obtainable. Isolating the infected person, handling the preventive techniques carefully might reduce the spreading of Ebola, and finally to conclude it is in the futures hand to find proper vaccine and drugs to stop Ebola.Reference listBaron, C.
