Course detail

Food Chemistry II

FCH-MCO_CHP2Acad. year: 2019/2020

The course Food Chemistry II focuses on minor components of human food. This is e.g. astrigent (bitter) substances, vitamins, colorants, flavorings, flavor and fragrance and additive substances. Students will become familiar with the structure and chemical properties of these minor ingredients. And in addition, with food commodities, which are the richest source of these. Maximum emphasis will, however, be placed on the study of reactions and changes, which the minor components are lieable to in technological processes of manufacturing and storage.

Learning outcomes of the course unit


Students will obtain the basic overview on important minority food ingredients, mainly on chemical properties of this ingredients, on structure and on reactivity.

Prerequisites

For successful completion of the course requires detailed knowledge of the basic components of human food, i.e. proteins, fats and saccharides.

Course curriculum

1. Water in food; 2. Harsh (bitter) matter; 3. Enzymatic turning brown; 4.Vitamins; 5. Fragrances and Flavours in food; 6. Flavor substances; 7. Shelf-life prolonging substances; 8. Aroma adjusting substances 9. Color regulating substances ; 10. Colorants - tetrapyrrols, flavonoids, carotenoids.

Aims


The objective of the course is to show students food as a complex of chemical compounds (mostly eatable and palatable) of specific features. The objective is to teach students to deduce appropriate conclusions from chemical features of these compounds. Students will apply this conclusions on all food technological operations.

Specification of controlled education, way of implementation and compensation for absences
