I Dimensions of food safety and quality

1 Food supply in a global and historic view and current food safety and quality demand
1.1 Population, area, yields and food supply on a global scale
1.2 All we come from developing countries: Agriculture and nutrition in the European history
1.3 Simple biological chain - versus agricultural supply chain
1.4 During the last century to more meat, milk and eggs in our food - Change in food habit by higher yields
2 Food safety, i.e. health protection by assessment, evaluation and management of the risks in the chain from primary production to the consumer
2.1. Chemical, microbiological and technological risks in raw material and food and their analysis - baselines of toxicological assessment/evaluation
2.1.1 Natural toxins - endogenous toxins of plant origin, microbial toxins, e. g. from bacteria or mould
2.1.2 Antinutritives (antiproteins, antiminerals, antivitamins)
2.1.3 Contaminants - heavy metals, nitrate, dioxin, residues of pesticides, antibiotics and "hormones", pyrolysis products, e.g. acrylamide, and further processing risks
2.1.4 Food additives
2.1.5 (Allergies and intolerances against certain food components, not treated in this lecture)
2.1.6 (Genetically modified organisms (GMO) as a risk in some markets, not treated in this lecture)
2.2 Food safety network
2.2.1 Standards, rules and regulations by WTO, WHO, FAO, FDA, EU, Germany
2.2.2 Institutions of risk analysis and the included reference groups and laboratories and their main tasks; institutions of risk management
2.2.3 Tasks and responsibilities of primary producers, food processors, food retailers and institutions of food safety control (by government and in the private sector)
3 Assessment and evaluation of food quality (besides the non-negotiable quality in terms of the safety)
3.1 Sensory quality - appearance, structure-consistency, aroma (odour + taste)
3.2 Nutritional quality - macronutrients, digestion, energy of exemplary food, nutrition- related diseases, micronutrients with regard to dietary allowances and to a possible too much, e.g. hypervitaminoses

4 Food quality on the market
4.1 Quality in the chain ? economic position of the operators and responsibilities, product liability, traceability
4.2 Consumer perception of food quality dimensions and consumer advice
4.3 Standard quality which is conformable to (minimum) requirements of legislation; food labelling
4.4 Special quality food (beyond the law level)
4.4.1 Products from quality programmes
4.4.2 Traditional products in the EU which are geographically protected or possess the status "protected origin"
4.5 Functional Food

II Production and safety/quality-chains of food, feed and selected non-food material


5 Grain and grain products
5.1 Grain species and production
5.2 Safety aspects, mainly regarding mycotoxins
5.3 Grading systems
5.4 Bakery products and their quality assessment
5.5 Alcohol from grain, also in the non-food sector ("Bioethanol")
5.6 Legume seeds in human nutrition

6 Oilseeds and oilseed products
6.1 Species and production
6.2 Vegetable oils - quality assessment
6.3 Oil in the non-food sector ("Biodiesel")

7 Roots and tubers - species, production, safety/quality and usage(s)

8 Milk and milk products
8.1 Milk production and nutritional value
8.2 Milk safety/quality on farm level and in the dairy (EU grading system for bulk milk)
8.3 Milk products - cheese and butter
8.4 Milk products with added value by modifying the milk fat and using further milk species (goat and sheep milk)

9 Meat and meat products
9.1 Meat production by farm animals and poultry and nutritional value of meat
9.2 Carcass grading for market-conformable meat and meat products
9.3 Standard and premium quality of fresh meat ? beef, pork, lamb and poultry
9.4 Meat products, mainly sausages of standard quality and of premium quality (specialities of regions, fat-optimized products)
