Food Technology II

Presentation

Food Technology has arisen from the need to preserve food longer, while retaining its specific natural characteristics and nutritional value. Today, it is still its goal to diversify the diet, ensuring the supply of nutritious and healthy food. It is a multidisciplinary field that involves knowledge in the areas of chemistry, biochemistry and nutrition and encompasses a set of techniques related to food production.

Food Technology II aims to provide knowledge on the main processes and equipment used in the dairy, fishery, egg and honey food industry, addressing the chemical composition and nutritional value of these foods and their modification mechanisms and processing technologies and the its effect on the chemical composition, structure, nutritional value and sensory value of foods.

2. Eggs

Structure and chemical composition. Technological properties. Physical-chemical changes during shelf-life.

Technology of egg products.

3. Honey and wax

Chemical composition. Changes during storage and analytical control parameters.

Collection and storage of honey and bee products

4. Fisheries

Composition. Post-mortem changes - technological implications in performance and functionality.

Analytical parameters for monitoring changes during storage.

Processing of fisheries products

Objectives

The UC Food Technology II aims to provide students with knowledge in the main processes used in the dairy, fishery products, eggs and honey industry:

1-Acquire knowledge about chemical composition and main mechanisms of change

2-Acquire knowledge about processing technologies and recognize and relate their effect on the level of chemical composition, structure, nutritional value and sensory

3-Acquire knowledge about dairy technology

4-Acquire knowledge about egg composition and structure, alteration during storage and technological processes of egg products

5-Acquire knowledge about the main methods of conservation and processing of fishery products.

6-Acquire knowledge about the process of honey collection and storage and analytical parameters to evaluate.

7-Evaluate and decide on the technology to apply according to available technologies, effects on the product and economic implications.

Teaching methodologies and assessment

Continuous evaluation

Theoretical: Exposure of the program synchronously on e-learning platforms; use of e-learning software (Moodle) to provide content and activities. Theoretical has a weight of 50% in the final grade and will be evaluated through a written test (65%) and activities (35%) launched during the classes. Approval with a minimum of 9.5 / 20 in the test.

Practice: Expository and demonstrative method of laboratory practices and food processing diagrams, using activities launched in Moodle, including viewing films about the processes applied in various food industries. Research work in supervised self-learning will also be carried out, with presentation to the class via Zoom. The practice has a weight of 50% in the final grade and will be evaluated continuously through a final test (40%) and research work (35%) and activities (25%) launched during the classes. Approval with a minimum of 9.5 /20.

Final exam for students who do not pass in the continuous evaluation.
