Assignment 1 (Sec A)- Shelf Life Management and Packaging(TFCH 3025) Name: Dylan Murphy Student Number: C12522373 Class: DT420/3 Lecturer: Nissreen Abu-Ghannam Assignment Due Date: 31/10/2014 Word Count: 1,606 Reference Word Count: 164 Introduction I have chosen four different types of methods to manage shelf life that are currently a new to the market. These methods are using editable coating made up of protective materials, films on packaging that allow diffusion of carotenoids from mono and bilayer polyethylene, Carboxymethyl cellulose–polyvinyl alcohol films and modified chitosan to improve antibacterial factors in packages. Each of these novel methods can be used to help increase shelf life but they do it in different ways. the shelf life …show more content…

To uncover organic compounds like carbohydrates, lipids, proteins and nucleic acid, by using tests like Benedict, Lugol, Biuret and Beta Carotene. Each test was used to determine the presents of different organic molecules in substances. The substances that were tested for in each unknown sample were sugars, starches, fats, and oils. Moreover, carbohydrates are divided into two categories, simple and complex sugars. Additionally, for nonreducing sugars, according to Stanley R. Benedict, the bond is broken only by high heat to make make the molecules have a free aldehydes (Benedict). As for Lipids, there are two categories saturated and unsaturated fats. One of the difference is that saturated fats are mostly solids and have no double bond (Campbell Biology 73). The Beta Carotene test works by dissolving in a lipid, thus giving it color to make it visible. Moreover, proteins are made out of amino acids that are linked by a polypeptide bond (Campbell Biology 75). The purpose of this experiment was to determine whether an unknown class sample or food sample had any carbohydrates, lipids, or proteins in it. The expected result of the lab was that some substances would be present while other would be absent.
In this case study, our concern goes for the chitosan nanoparticles; firstly nanoparticles are able to adsorb and/or encapsulate a drug, thus protecting it against chemical and enzymatic degradation. Furthermore the encapsulated drug may be prevented from crystallization, thus forming a solid solution. Depending on drug solubility in the carrier, a drug load varying from only a few percent up to 50%] Secondly, chitosan is ...
Service life The service life of the antioxidants is long but not that long. This is because if the additive starts to weaken due to the harmful polymer oxidation chemicals in the air then this could make the polymer properties to become brittle.
Joshi et al. (2009) argue that compared with non perishable supply chain, the perishable food cold chain costs are higher in transportation, because the perishable food is to be kept in the refrigerator in order to maintain the quality of the food. What is more, no matter in transportation or storage, different products require different temperatures. E.g. milk should be stored at 4 degrees to 10 degrees, while cheese should be kept at 3 to 5 degrees (Manning et al., 2006).
According to §2 para. 6 No. 2 of the German food law, cosmetic packaging materials are viewed as items for everyday and common use. The Regulation 1223/2009 provides assurance to consumers that the product they use is safe for application. The reference 1935/2004 was suggested to portray close formulation/packaging combinations that are already present in the market. Therefore, with this, food/packaging interaction may be contemplated. Since materials manufactured for the packaging of food products have already undergone several tests, suitable information regarding the stability of that material may already be accessible. Hence further experimental procedures may not be necessary. The 1935/2004 regulation is not normally used for cosmetic packaging. However, without the presence of any other established guidelines, this regulation is used to check the congruity of the packaging. For instance the packaging material of cosmetic products are compared with and judged against the packaging of food items. Verification in the shipping document is done by the food control agency or the supplier company to show that the packaging material
According to researches packaging has progressed from containers provided by nature, to the more complexed use of materials and process providing a change to what is displayed on the grocery shelves today. Several factors contributed to the reason for packaging of which included, competition in the marketplace as well as shifting lifestyles, as the market of goods grew, consumers went from purchasing goods they needed to selecting a product based on the unique design and label to decorate their counter tops, making consumer choice a very large factor in packaging.
Interestingly, the effect of microwave- and conventional- blanching (90C) on red beet was studied by Latorre et al. (2012). They showed that integrity of the red beet cell wall was retained, when red beets were exposed to microwave blanching in water, and such treatment prevents red beet tissue damage from the heat transfer. However, direct exposure of microwaves causes significant shrinkage and excessive water loss from the red beet tissues (Latorre et al., 2012). Moreover, Latorre et al. (2013) further demonstrated that microwave blanching at constant 350 W (treatment: 5 minutes and venting: 1 minute) causes inactivation of 90% degradative enzymes, and increases the polyphenol content due to modification of red beet cell wall in such a manner under the conditions. The research group also concluded that raw beet possess thick middle lamellae without separation between the neighbouring cells and at tri-cellular junction corners, however, treatment of red beets by microwave blanching retains the contacts between the neighbouring cells with separations of middle lamellae mainly at corners, promoting hydrophilicity and macromolecular mobility of bioactive compounds, and conventional (90 C) and high power (> 900 MW) microwave blanching leads to
This method is usually carried out on ready to eat food and processed meat and poultry. This method is a proven way to extend shelf life by killing microorganisms and pathogens, which are the reason processed meat such as deli meats last so long. However, there are negative effects of this method. There is a change in nutritional value and sensory value in foods that have been used in this process. It can change the flavour and can cause vitamin and protein destruction. However, non-thermal methods offer an extension in shelf life without changing the sensory values or nutritional values. It is a low cost method of food processing also. Non thermal methods have a big place in the future of food processing as consumers are becoming more aware of the nutritional value of the food, as well as wanting to save money and enjoy the flavour of the
The purpose of this experiment was to determine the amount of all-trans-lycopene present in a can of tomato paste in order to determine the quality of the tomato paste. This was achieved by proper separation of lycopene from the other pigments in the tomato paste through column chromatography. The column was able to achieve proper separation given the high polarity of the packing, alumina. Given alumina’s high polarity, the pigments present in the tomato paste with a greater polarity would travel more slowly through the column than the molecules with a lower polarity. Due to the fact that each pigment presented as a different color, in addition to variations in polarity, the separation of lycopene was made possible. The yellow band, composed of carotenes, traveled the quickest through the column, suggesting it was the least polar pigment present. If it were more polar, it
As the world moves towards new discoveries, inventions, life styles have been drastically altered as well, the homo sapiens that we use to know have evolved themselves, in every field of life. However, when it came down to food, there has always been a risk of hazards and the intake of chemically synthesized material which has become a blessing and a consequence that we have to pay for the modernism. Yet, the demand for safer and fresh produce still remains a question. As the world population increases by the every second, the need for greater food supply keeps on growing. For this bigger demand preservation of food becomes a necessity. And this is where the word food additives begin. Food additives have gotten a major attention in the food scientist of the world, and are the most visited areas of science now.

Antimicrobial Packaging: Edible films are produced which incorporate cinnamon, zinc, calcium, oregano oil or other materials that can kill bacteria.
Consumers have expectations In terms of a good quality product that should be availed at a reasonable price. Consumers don’t only want the business to be socially responsible towards them in this manner of reasonable prices but way beyond this. They should meet the needs of consumers in ways of convenience and appearance. But business should also consider other aspects like environmental impact when packaging is disposed.

Law, Abu Bakar, Mat Hashim, and Abdul Hamid (2011) concluded that fermentation is one of the oldest and widely used food preservation methods in households, small-scale food industries as well as in large enterprise. Fermented foods generally preserved pleasant flavor, aroma, texture, enhanced nutritive values and good keeping quality under ambient conditions. (p.1)
