Study Notes
History of Food Microbiology
- Early food preservation: 900 AD - "Food Poisoning" recognized
- 1795 - Appert developed canning
- 1854-1864 - Food Microbiology becomes a science, thanks to Louis Pasteur
Importance of Food Microbiology
- Provide clean, safe, healthful food to consumers
- Control microbial growth to prevent food spoilage and food-borne illnesses
- Preserve and produce food using microorganisms
Microorganisms in Food Production
- Bacteria, viruses, and fungi (yeasts and molds) are microorganisms used in food production
- Some microorganisms are undesirable, causing spoilage or illness, while others are used to make food
- History of microorganism use in foods: cheese, yogurt, bread, wine, and beer production
Microorganisms in Food
- Microorganisms are used to make cheese, yogurt, and bread
- Yeasts are used in bread production to ferment sugars and produce carbon dioxide
- Lactic acid bacteria are used in sourdough bread to provide a sour taste
- Moulds are used in blue cheese production to give it a unique characteristic
- Bacteria are used in yogurt production to thicken milk and provide a sour taste
Fermented Foods
- Soy-based products: soy sauce, miso soup, tempeh, and fermented meat and fish products
- Fermented vegetables: kimchi, sauerkraut, pickled gherkins, and condiments like yeast extract, Worcestershire sauce, and hot sauce
- Drinks: kombucha, kvass, and vinegar
- Mycoprotein: a meat alternative made from fungus
- Chocolate: fermented cocoa beans are used to make chocolate
Food Safety
- Food safety is divided into three categories: biological, chemical, and physical hazards
- Indicators of food microbial quality and safety: predictive microbiology and microbial modeling
