Model Answer
0 min readIntroduction
Ghee, clarified butter, holds immense cultural and nutritional significance in the Indian subcontinent. It’s a staple in traditional Indian cuisine and is deeply embedded in religious practices. The process of transforming butter into ghee involves removing milk solids, resulting in a rich, aromatic, and shelf-stable product. Increasing consumer awareness regarding health and quality has prompted a closer look at ghee manufacturing processes and adherence to stringent quality standards. The Food Safety and Standards Authority of India (FSSAI) and Agmark play vital roles in ensuring the quality and safety of ghee available to consumers. This answer will discuss various ghee manufacturing techniques, their merits and demerits, and the relevant Indian standards.
Ghee Manufacturing Methods
1. Traditional/Handmade Method (Ghio)
This method is the oldest and most authentic way of ghee production, typically done in rural households. It involves simmering butter in earthen pots or iron vessels until the milk solids separate and settle at the bottom.
- Process: Butter is slowly heated in an earthen pot or iron vessel. The simmering process continues until the milk solids (sediments) settle down and the clear, golden-yellow liquid (ghee) is skimmed off.
- Merits: Considered to be the purest form of ghee, imparts a unique flavor due to the interaction with earthen/iron vessels, retains maximum nutrients.
- Demerits: Time-consuming, labor-intensive, difficult to scale up for commercial production, inconsistent quality depending on the skill of the maker, potential for contamination if hygiene is not maintained.
2. Batch Processing Method (Industrial Scale – Traditional Approach)
This method is a scaled-up version of the traditional method, often used by small to medium-sized dairies.
- Process: Butter is heated in stainless steel or aluminum vessels in batches. The process is monitored for temperature and time. Sediments are removed, and the ghee is cooled and packaged.
- Merits: Relatively simple and cost-effective, retains some of the traditional flavor profile.
- Demerits: Quality control can be challenging due to batch variations, potential for overheating and affecting ghee's nutritional value, still relatively time-consuming compared to continuous methods.
3. Continuous Ghee Manufacturing Method
This is the most modern and widely adopted method for large-scale ghee production.
- Process: Butter is fed continuously into a series of heat exchangers and evaporators. The milk solids are separated, and the ghee is collected. Sophisticated control systems maintain consistent temperature and pressure.
- Merits: High production capacity, consistent quality, automated process reduces labor costs, allows for better control of parameters like temperature and time.
- Demerits: Higher initial investment cost for machinery, can sometimes compromise the unique flavor profile associated with traditional methods, requires skilled technicians for operation and maintenance.
4. Butter Oil Ghee (BO-Ghee)
This method involves converting butter oil (a refined form of butter) into ghee. It's often used to produce ghee with a consistent color and flavor.
- Process: Butter oil is heated, and any remaining milk solids are removed. This process can be modified to impart a desired flavor profile.
- Merits: Provides greater control over color and flavor, can be produced consistently.
- Demerits: May not be considered "authentic" ghee by some consumers, relies on the quality of the butter oil used.
| Method | Production Scale | Quality Control | Flavor Profile | Cost |
|---|---|---|---|---|
| Traditional (Ghio) | Household/Small | Low | Unique, authentic | Low (labor intensive) |
| Batch Processing | Small to Medium | Moderate | Somewhat traditional | Moderate |
| Continuous | Large | High | Consistent, less traditional | High (initial investment) |
| BO-Ghee | Medium to Large | High | Controlled, consistent | Moderate to High |
FSSAI and Agmark Standards for Ghee
1. FSSAI Standards (Food Safety and Standards Authority of India)
The FSSAI regulates ghee production and sale in India under the Food Safety and Standards Act, 2006. Key parameters include:
- Fat Content: Minimum 99% fat on a dry matter basis.
- Acid Value: Not more than 0.5.
- Peroxide Value: Not more than 5.
- Iodine Value: Minimum 45.
- Color and Odor: Should be characteristic of ghee.
- Additives: No artificial colors or preservatives are permitted.
- Labeling Requirements: Mandatory declaration of nutritional information, expiry date, and FSSAI license number.
2. Agmark Standards
Agmark is a quality certification mark issued by the Directorate of Marketing and Inspection (DMI) under the Ministry of Agriculture and Farmers Welfare. Ghee conforming to Agmark specifications receives this certification, indicating adherence to higher quality standards.
- Fat Content: Minimum 98.5% fat on a dry matter basis (higher than FSSAI minimum).
- Acid Value: Not more than 0.4 (stricter than FSSAI).
- Peroxide Value: Not more than 3.
- Iodine Value: Minimum 50.
- Other parameters: Similar to FSSAI standards for color, odor, and absence of adulterants.
Agmark certification is voluntary but provides a competitive advantage to ghee manufacturers.
Conclusion
Ghee manufacturing encompasses a spectrum of processes, from traditional handmade methods to modern continuous production. While traditional methods are valued for their authentic flavor and perceived purity, modern techniques prioritize efficiency and consistency. The FSSAI and Agmark standards serve as crucial safeguards, ensuring the quality and safety of ghee for consumers. Adherence to these standards, coupled with continuous technological advancements, will be vital for the sustainable growth of the Indian ghee industry and maintaining its cultural significance.
