Teaching in the second semester

Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The course is made of 5 main sections:


  • 1 : overview of the lipids field : the main families of lipids are described along with main methods of classification and characterisation/quality control of fats.
  • 2 : Oils and fats technology : All operations ranging from preparation of raw materials (seeds, fruits) to the refining of the extracted oil (degumming, bleaching, deacidification, deodorization, ...) are discussed.
  • 3 : Physico-chemical Properties : thermal properties of lipids and fat crystallization. (polymorphism and intersolubility).
  • 4 : Oils and fats modifications : hydrogenation, interesterification, fractionation are presented
  • 5 : Formulation of fat containing products (edible or not): technological aspects
 

Learning outcomes of the learning unit

The industry of extraction, refining and transformation of oils and fats constitutes a specific sector of food industries because of the hydrophobic nature of the concerned components. At the end of the formation, the students will be able to determine the constraints linked to this specificity in order to optimize oils and fats functionality.
 

Prerequisite knowledge and skills

Thermodynamics (bachelier), organic chemistry, mass transfert, heat transfert, food processings, food formulation engineering, formulation physicochemistry

Planned learning activities and teaching methods

Lectures 
Practical works are intended to illustrate the theory.
Attendance at practicals is mandatory.
In these sessions, students perform themselves various experiments grouped into themes.
Several practical works imply pilot material (CARE FoodIsLife).
If possible, a company visit will be organized. (due to covid crisis, not possible in 2021)
 

Mode of delivery (face to face, distance learning, hybrid learning)

Lectures  (remotely or hybrid due to covid crisis)
 
Practical Works (lab and pilot scale)  literaturte project  
 

Organisational adjustments related to the current health context

Lectures will be done remotely using collaborate and/or podcasts
If possible, practicals will be organized face-to face (TERRA).
A literature review will be asked 
Lab report and literature review will be evaluated
Final oral examination 
 

Recommended or required readings

A copy of the slides is available for students ("myuliege")
 
Usefull books :
"The lipid handbook" - ED F. Gunstone, J. Harwood, A. Dijkstra (CRC Press)
"Fat crystal network" - ED A. Marangoni (Marcel Dekker)
"Crystallization and solidification properties of lipids" - N.Widlak, R.Hartel, S.Narine (AOCS Press)

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

oral exam

- Remote

oral exam AND written work

- If evaluation in "hybrid"

preferred remote
