Assessment Task 2
Food Manufacture

Part A – Analysis and preparation
1. a) Select a preserve (jam, chutney, pickle) and submit a computer generated copy of the recipe.
Strawberry jam recipe submitted.
b) Identify ALL raw materials that would be used in the production of your selected preserve.
A raw material can be defined as any product that is used in the manufacture of another food.
Strawberry jam
Ingredients – fresh strawberries, lemon, sugar
Materials – heat
Food additives – nil
Packaging – glass jars with lids.
c) Complete an accurate food order. If necessary, adjust quantities for a maximum of 2 jars of preserve.
(Makes approximately600grams of jam.)
500gms fresh strawberries
500grams sugar
½ tablespoon of freshly squeezed lemon juice
2. a) Identify FOUR reasons for preserving foods. Relate to your selected preserve.
Strawberry jam
The main reasons for preserving strawberries as jam are:
To keep the fruit safe for human consumption in a state acceptable for the consumer and so reduce waste.
To retain the nutritive value of the fruit.
To make strawberry jam available all year round which provides for a wider variety of choices in the consumers diet.
To achieve economic viability for producers of strawberries by reducing seasonal fluctuations in availability.

b) Outline ALL principles of preservation used in the production of your preserve.
Temperature control – micro-organisms grow or produce toxins in specific temperature ranges. The application of high temperature is used in the production of strawberry jam. Preservation method – sterilisation.
Restriction of moisture – The amount of available water in the preserve will determine whether an organism can grow. The use of sugar in the production of strawberry jam reduces the available water.
Exclusion of air – Most organisms require the presence of oxygen to grow. The heating of the preserve, strawberry jam and then the placement of the jam

    Proper postharvest processing and handling is an important part of modern agricultural production. Postharvest processes include the integrated functions of harvesting, cleaning, grading, cooling, storing, packaging, transporting and marketing. The technology of postharvest handling bridges the gap between the producer and the consumer - a gap often of time and distance. Postharvest handling involves the practical application of engineering principles and knowledge of fruit and vegetable physiology to solve problems.…

    • NCC received both fresh fruit and process fruit in its business. Fresh fruit is a labor-intensive process that uses more workers during a peak season. Process fruit is a highly mechanized process that uses different processes. There is no problem with fresh fruit processing, while it faced some problems in process fruit processing such as waiting time on unload process, increasing cost of trucks etc. (National Cranberry Cooperative, 1983).…

    Hurdle Technology

    HURDLE TECHNOLOGY The spoilage and poisoning of foods by micrnorgenisms is a problem that is not yet under adequate control, despite the range of preservation techniques available (e.g. freezing, blanching, pasteurizing and canning). In fact, the current Consumer demand for more natural and fresh-like foods, which urges food manufacturers to use only mild preservation techniques (e.g. refrigeration, modifed-atmosphere packaging and bio-conservation), should make this problem even greater. Thus, for the benefit of food manufacturers there is a strong need for new or improved mild preservation methods that allow for the production and fresh-like, but stable and safe foods. The concept of hurdle technology is not new but addresses this need in full. Hurdle technology (also called combined methods, combined processes, combination preservation, combination techniques or barrier technology) advocates the deliberate combination of existing and novel preservation techniques in order to establish a series of preservative factors (hurdles) that any microorganisms present should not be able to overcome. These hurdles may be temperature, water activity (a,), pH, redox potential, preservatives, and so on. It requites a certain amount of effort from a microfganism to overcome each hurdle. The 'higher" the hurdle, the greater the effort (i.e. the larger the number of orgenisms needed to overeome it). Some hurdles, like pasteurization, can be high for a large number of different types of microorganisms whereas others, like salt content, have a less strong effect or the effect is limited in the range of types of microorganisms it effects. The fact that a combination of preservative factors influences the microbial stability and safety of foods has been known for many centuries. Tbe concept is more or less unconsciously used in many traditional foods, especially in the developing…

    There were measurements of Plant height (cm), number of leaves; numbers of branches, total fresh and dry weights per plant were recorded in the end of the growing season. Weight and number of fruits in total and marketable yields were recorded from each replicate. Average individual fruit weight was also calculated from these data. There were also some chemical measurements to determine the Soluble Solids Contents (SSC) in fruit sap. The total content of some nutrients such as N, P, K and Ca were also determined in the leaves.…

    Once the strawberry pulp was obtained, the heated salt water detergent was added. As mentioned before, this solution contains water, detergent and salt, and it’s kept warm at 60 degrees Celsius. This mixture plays a major role is dissolving the lipids and proteins that are main constituents of the cell membrane. The latter is known to be made of a bilayer containing phospholipids with hydrophilic heads and hydrophobic tails, in addition to several proteins that are located throughout mosaic fluid. The detergent solution is believed to have the same characteristic and thus, complexes comprised of detergent and the lipids and proteins are formed, which results in the membranes being broken down. The detergent…

    TETRANCHUS URTICAE AND THE GREENHOUSE STRAWBERRY PLANT Mites belong to the Chelicerata, a branch of arthropods and the second largest group of terrestrial animals. Within the order Acari, spider mites belong to the Acariformes with fossils dating from the Lower Devonian period 410 million years ago (Edgecombe, G. D., 2010). The two-spotted spider mite, Tetranychus urticae, is a web-spinning mite. The name refers to their ability to produce silk-like webbing used to create a colonial micro-habitat, protect against predators, communicate via pheromones, and provide a vehicle for dispersal.…
