# Laboratory Report on Dairy Processing Equipment and Yogurt Making
## Introduction
Dairy processing is a crucial aspect of the food industry, employing various specialized equipment to conduct operations such as pasteurization, fermentation, and product creation. This report focuses on the observation of dairy processing equipment, including milko scan, icinac, cheese bath, water bath, butter churner, sterilizer, and pasteurizer, followed by an exploration of yogurt making utilizing a commercial starter culture.
## Objective
- To observe and understand the functionality of various dairy processing equipment.
- To make yogurt using a commercial starter culture and evaluate its properties, including pH level.
## Materials Used
### Equipment
1. **Milko Scan**: For measuring the composition of milk (fat, protein, lactose).
2. **Icinac**: For monitoring the acidity of the milk.
3. **Cheese Bath**: For curdling milk and aiding in cheese production.
4. **Water Bath**: For maintaining optimal temperatures during yogurt fermentation.
5. **Butter Churner**: For processing cream into butter.
6. **Sterilizer**: To sterilize equipment and milk prior to processing.
7. **Pasteurizer**: To heat milk to eliminate bacteria.
### Ingredients
- 50 ml of milk
- **Commercial Starter Culture**: Contains live bacterial cultures needed for yogurt fermentation.
## Procedures
### Observing Dairy Processing Equipment
1. **Milko Scan**: Observed its operation in determining the fat, protein, and lactose content in milk, aiding in quality control.
2. **Icinac**: Used to monitor the acidity of the milk, ensuring it falls within acceptable limits prior to processing.
3. **Cheese Bath**: Analyzed the curdling process of milk when warmed and combined with specific conditions.
4. **Water Bath**: Evaluated its use in maintaining consistent temperatures during yogurt fermentation.
5. **Butter Churner**: Observed the physical process of emulsification and churning of cream into butter.
6. **Sterilizer**: Inspected for its role in eliminating microbial contaminants before processing.
7. **Pasteurizer**: Understood the method for rapid heating of milk to kill harmful bacteria while preserving taste and nutritional value.
### Yogurt Making
1. **Preparation**: Sterilize all equipment and utensils.
2. **Milk Heating**: Heat 50 ml of milk to 85°C using the pasteurizer, then cool it down to about 43°C.
3. **Adding Starter Culture**: Introduce the commercial starter culture to the cooled milk.
4. **Fermentation**: Place the mixture in a water bath maintained at 43°C for 4-6 hours to allow fermentation to occur.
5. **pH Measurement**: After fermentation, measure the pH of the resultant yogurt, which should be around 6.26.
## Discussion
The observation of the dairy processing equipment provided insights into the critical roles these devices play in the production of dairy products. Each piece of equipment serves a specific purpose that collectively contributes to maintaining hygiene, efficiency, and quality in dairy processing.
In the yogurt-making process, the measured pH of 6.26 indicates that the yogurt is in a relatively neutral range. Various factors like temperature, fermentation time, and the quality of the starter culture significantly influence the pH and the final product characteristics. Ideally, the pH of yogurt should fall within the range of 4.0 to 4.6 for optimal flavor and preservation.
## Results
- Observations on the functionality of dairy processing equipment were successful, noting the unique contributions of each appliance.
- The yogurt-making process yielded a final product with a pH of 6.26.
## Conclusion
The laboratory exercise successfully demonstrated the importance of various dairy processing equipment and the methodology required for yogurt production. Impacts on pH and product quality were noted, emphasizing the need for precise temperature control and starter culture selection.
## Recommendations
- Future experiments should explore varying fermentation times and different starter cultures to assess their impact on yogurt flavor and texture.
- Regular maintenance and calibration of equipment like the milko scan and icinac are recommended for ensuring accurate readings and product quality.
