Study Notes
Applied Microbiology Focus
- Centers on the practical application of microbial sciences to address human needs and solve problems in various fields.
- Involves research and utilization of microorganisms in health, agriculture, and industrial processes.
Purpose of Microbes in Applied Microbiology
- Key purpose includes the development and improvement of products such as food, pharmaceuticals, and biofuels through microbial processes.
Milk to Yoghurt Conversion
- The process of fermentation is commonly used to convert milk into yoghurt.
Microbes in Cheese Production
- Lactic acid bacteria, particularly species like Lactococcus lactis and Streptococcus thermophilus, are commonly used in cheese production.
Initial Step in Milk Product Production
- Pasteurization is the first step taken when producing milk products like yoghurt and cheese, aimed at eliminating harmful microorganisms.
Compound for Buttery Flavor in Dairy
- Diacetyl is the compound responsible for the buttery flavor in dairy products like yoghurt.
Bacterial Strains in Yoghurt Production
- Specific bacterial strains, such as Lactobacillus bulgaricus and Streptococcus thermophilus, are added to milk for industrial yoghurt production.
Compound for Dense Yoghurt Consistency
- Pectin contributes to the dense consistency of yoghurt during production.
Taste Development in Yoghurt
- The characteristic tangy taste of yoghurt develops due to the production of lactic acid by fermentation from the added bacterial cultures.
Enzyme for Dense Cheese Texture
- Rennet, containing the enzyme chymosin, is traditionally used to impart a dense texture to cheese during its production.
Improving Yogurt Shelf Life and Probiotic Properties
- Techniques like low-temperature pasteurization and the addition of stabilizers enhance the shelf life and probiotic characteristics of yoghurt during manufacturing.
Cheese Types Based on Storage Duration
- Cheese varieties such as cheddar and gouda are formed after storing freshly prepared cheese for 3 to 12 months, allowing flavor and texture development.
