Key words
Instrumental techniques - food analysis
Objectives
The main objective is to provide a more solid and profound scientifically basis (fysico-chemical) which in practice gives access to the application of a great variety of qualitative and quantitative applied analytical methods usefull in food analysis.
Topics
Theory:
- Instrumental characteristics
- Electrochemical methods: conductometry, potentiometry, electrolysis, voltammetry, amperometry, coulometry
- Optical methods: interaction electromagnetic radiation (matter,molecular and atomic absorption/emission (UV - VIS, IR, FT-IR, NIRA, RAMAN, turbidimetry, nefelometry, refractometry, polarometry, flame photometry, ICP, AES, AAS, XRF, chemiluminescence,... (depending on timeschedule)
The analytical methods are illustrated with applications in food analysis.
Exercises
- GC: determination of fats
- HPLC:determination of vit C ( extern en intern standardisation )
- Spectroscopy: fluorimetric determination quinine in tonic
- TLC: determination of biphenyl en ortho phenyl phenol in citrusfruits
- ISE: use of ion selective electrode (determination nitrate in vegetables)
- extern standard en multiple standardaddition
- Demonstrations: GCMS , SPE en SPME
C-hours : productquality, quality-assurance and legislation
Prerequisites
Basic knowledge of inorganic - organic chemistry (candidatures) and analytical chemistry (chemical analysis)
Final Objectives
- The student has to think and argue in a logical, critical and scientific manner and to implement scientific insights on related problems. At the same time he must be able to communicate verbal and/or written in an efficient manner;
- The student must have insight to the different scientific/technical disciplines;
- The students have to perform quality minded and has to take care of the environmental - , safety- and health aspects;
- The students must obtain a clear insight into chemical general knowledge and basic skills and must be able to link the different aspects and apply them in process- and productcontrol;
- Via the practical exercises, the mentioned objectives are persuited and other qualifications as team spirit are also emphasized.
