Chhana, a key ingredient in many Indian dairy-based sweets, plays a crucial role in the dairy and food processing industry. This article explores the yield factors, packaging techniques, preservation methods, shelf life, and defects associated with chhana—essential knowledge for any food consultant, dairy processing consultant, or food manufacturing consultant aiming to optimize quality and compliance in chhana production.
Chhana Yield in Dairy Processing
The yield of chhana typically ranges between 10% to 15% of the total milk volume, depending on various factors such as:
- Milk quality and fat content
- Acidity levels
- Processing techniques used during coagulation
For example, high-fat milk generally leads to higher chhana yield, making it more cost-effective for food processing consultants and dairy technologists to optimize milk sourcing and handling procedures.
Packaging and Preservation of Chhana
Proper packaging and preservation are critical for maintaining product safety, shelf life, and consumer satisfaction in the dairy industry.
Common Packaging Methods
- Food-grade plastic wrap or pouches (moisture-resistant)
- Vacuum-sealed containers
- Brine solution packaging (for extended shelf life)
Preservation Practices
- Store chhana in a refrigerated environment below 4°C (39°F)
- Use antimicrobial packaging materials when possible
- Avoid cross-contamination through hygienic handling practices
Food consultancy services often recommend integrating smart packaging solutions and cold chain logistics to extend the shelf life and reduce product losses in commercial food manufacturing.
Shelf Life of Chhana
Under ideal refrigerated conditions, chhana can remain fresh for 5 to 7 days. However, shelf life is influenced by:
- Initial microbial load
- Packaging material and method
- Temperature consistency during storage
Food industry consultants and QA experts in dairy plants must conduct periodic testing to verify shelf life and microbial safety, ensuring compliance with FSSAI and international food safety standards.
Common Defects in Chhana and Their Causes
Several quality defects can occur due to improper processing or storage:
1. Sourness
- Caused by bacterial contamination
- Occurs when stored beyond its safe shelf life
- Results in off-flavor and undesirable odor
2. Texture Changes
- Can become too soft, crumbly, or grainy
- Usually due to improper acidification or curdling
3. Mold Growth
- Caused by exposure to air or moisture
- Sign of inadequate packaging or hygiene failure
- Moldy chhana is unsafe for consumption
To mitigate these issues, engineering consulting firms specializing in food plant design often recommend automation and cleanroom integration in dairy processing units.
Best Practices for Quality Chhana Production
For high-quality and safe chhana manufacturing, food technology consulting experts recommend:
- Ensuring strict hygiene protocols
- Investing in advanced dairy processing equipment
- Conducting regular quality control and shelf-life testing
- Providing staff training on GMP and HACCP principles
These measures are essential for food business consultancy clients aiming to enter or scale within the dairy sector.
