Vocabulary Review:
Next, review the vocabulary table provided below to familiarize yourself with key terms related to the yogurt industry.
Term | Definition | Example Usage |
---|---|---|
Organoleptic | Relating to the senses, especially taste and smell, used to evaluate the quality of milk. | The organoleptic examination of milk involves checking its appearance, smell, and taste to determine its quality. |
Homogenization | The process of reducing the size of fat globules in milk to prevent separation and improve consistency. | Homogenization is a crucial step in milk processing to ensure a uniform texture and prevent cream separation. |
Thermization | A heat treatment process that involves heating milk to 63-65°C for 15-20 seconds to inhibit bacterial growth and enzyme activity. | Thermization is used to extend the shelf life of milk and improve its safety by reducing the risk of bacterial contamination. |
Pasteurization | A heat treatment process that involves heating milk to 90°C for 15 minutes to kill pathogenic microorganisms and extend shelf life. | Pasteurization is a critical step in milk processing to ensure the safety and quality of the final product. |
Ultra-filtration | A process that uses a semipermeable membrane to separate particles and remove impurities from milk, resulting in a concentrated and purified product. | Ultra-filtration is used to produce high-quality Greek yogurt with increased protein and fat content. |
Starter Culture | A mixture of microorganisms, such as bacteria and yeast, added to milk to initiate fermentation and produce yogurt. | The starter culture is essential for converting milk into yogurt, and its composition can affect the final product’s texture, flavor, and nutritional content. |
Incubation | The process of maintaining a controlled temperature and environment to allow the starter culture to ferment the milk and produce yogurt. | Incubation is a critical step in yogurt production, as it allows the starter culture to grow and convert the milk into a fermented product. |
Refrigeration | The process of cooling and storing yogurt at a low temperature to slow down bacterial growth and extend shelf life. | Refrigeration is essential for maintaining the quality and safety of yogurt, and it involves storing the product at a consistent temperature below 8°C. |
Clarification | The process of removing impurities and sediment from milk to improve its appearance and quality. | Clarification is an important step in milk processing, as it helps to remove unwanted particles and improve the final product’s texture and appearance. |
Deodorization | The process of removing unwanted odors and flavors from milk to improve its quality and taste. | Deodorization is used to remove volatile compounds and other impurities from milk, resulting in a cleaner and more neutral flavor. |
