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 components.
The main learning objective is to lead students to master the basic knowledge necessary for them to be able to fit into a global production chain in the food industry, and to occupy different positions (R&D , production, quality control, etc.), and this, in the many types of companies in the oils & fats sector (refineries, oil mills, margarine factories, chocolate factories, equipment manufacturers, etc.).
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).
A visit of a company of the oils and fat sector will be organized.
Mode of delivery (face to face, distance learning, hybrid learning)
Blended learning
