# Laboratory Report on Dairy Processing and Yogurt Making
## Introduction
Dairy processing equipment plays a crucial role in the production of various dairy products, including milk, cheese, yogurt, and butter. This report focuses on observing various dairy processing equipment and the practical application of making yogurt using a commercial starter culture. The importance of each equipment in maintaining product quality and safety will be discussed.
## Objective
1. To observe and understand the functionality of various dairy processing equipment.
2. To make yogurt using a commercial starter culture and quantify its pH level post-production.
## Materials Used
### Equipment Observed
- Milko Scan
- Icinac (Ice Cream Maker)
- Cheese Bath
- Water Bath
- Butter Churner
- Sterilizer
- Pasteurizer
### Yogurt Making
- 50 ml of milk (whole or skimmed as applicable)
- 2 grams of commercial yogurt starter culture powder
- pH meter for measuring acidity
## Procedures
### Observation of Dairy Processing Equipment
1. **Milko Scan**: This device was observed for its ability to analyze milk composition, including fat and protein content through infrared technology.
2. **Icinac**: Observed the machine’s procedure for making ice cream consistent with industry standards.
3. **Cheese Bath**: This equipment was utilized for controlling the temperature of the curds during cheese making, ensuring optimal texture.
4. **Water Bath**: Used to maintain constant temperatures for various dairy processes, it was analyzed for its effectiveness in controlling heat during the yogurt incubation phase.
5. **Butter Churner**: Observed the mechanics of cream separation into butter and the necessary churning time for optimal butter extraction.
6. **Sterilizer**: We examined the efficacy of this equipment in eliminating pathogenic microorganisms from dairy products.
7. **Pasteurizer**: Observed the principles of pasteurization, including time and temperature principles used to ensure dairy safety.
### Yogurt Making Procedure
1. Heat the 50 ml of milk to 85°C for 3 minutes to kill any unwanted bacteria.
2. Allow the milk to cool to 42°C.
3. Add 2 grams of the commercial yogurt starter culture to the cooled milk, ensuring it is evenly distributed.
4. Incubate the mixture at a constant temperature of approximately 42°C for 4-6 hours in a water bath.
5. After incubation, cool the yogurt to stop bacterial activity using the ice water method.
6. Measure the final pH of the yogurt using a calibrated pH meter, which was measured to be 6.26.
## Discussion
The various dairy processing equipment serves specific functions critical to processing high-quality dairy products. Each piece of equipment ensures that dairy processing adheres to standards that prevent contamination and maintain nutritional quality. The yogurt making process demonstrated the importance of temperature control, sanitation, and the role of starter cultures in fermentation. The pH of the finished yogurt being 6.26 indicates a mildly acidic product, which can be favorable for taste and preservation.
## Results
- Final pH level of the yogurt: **6.26**
- Observations from equipment: Each equipment performed as expected, with the pasteurizer exhibiting excellent pasteurization efficiency and the milko scan providing reliable composition analysis.
## Conclusion
This laboratory report successfully outlined the functionality of dairy processing equipment essential for the transformation of raw milk into safe and high-quality dairy products. The process of making yogurt demonstrated the scientific principles behind fermentation and the critical role of pH in determining product quality.
## Recommendations
1. Regularly maintain and calibrate dairy processing equipment to ensure accuracy and effectiveness.
2. Utilize real-time monitoring systems for temperature and pH during fermentation to enhance yogurt production quality.
3. Explore the impact of different strains of starter cultures on yogurt flavor and texture for product development.
