Short description:

The course includes the following classes:

- lecture 20 hrs.

- laboratory 40 hrs.

The subject is to provide basic knowledge in the field of testing the quality of food products. In addition, as part of the laboratory, students independently carry out exercises in chemical and microbiological analysis of food.

Full description:

The lecture is designed to familiarize students with the basic information on natural food ingredients (proteins, carbohydrates, fats, minerals, water, vitamins) and additives, their characteristics and methods of quantitative and qualitative analysis. In addition, it covers the discussion of microbiological hazards of food, including: microbiological degradation of food ingredients and their impact on the sensory quality of food, food poisoning and infections (characteristics, pathogenic bacteria and their toxins, toxic fungi and mycotoxins, viruses); indicator microorganisms; microflora of selected raw materials and food preparations. The influence of food preservatives on the survival of microorganisms is discussed.

The laboratory is devoted to familiarizing the student with the methods of collecting and preparing food samples for analysis and the analytical procedures used in food research.

Laboratory classes include the following exercises:

1. Spectrophotometric determination of vitamin E in oils

2. Determination of the content of thiocyanates in cruciferous plants

3. Determination of selected nutrients in milk

4. Analysis of the freshness of processed fruit and vegetables

5. Electrochemical methods in food analysis

6. Determination of the antioxidant activity of spices

7. Determination of synthetic and artificial dyes in preserves

8. Determination of pectin content in raw materials and food products 9. Preparation of nutrients and samples of selected raw materials and food products for microbiological analysis,

10. Assessment of the microbiological quality of food and its suitability for consumption (microbiological tests for the assessment of the freshness of food products)

11. Methods for determining the microflora of food packaging (washings method, direct method (Richter))

12. Determination of the content of selected test microorganisms in food products.
