Oversees the entire process, ensures that adjustments are made correctly, and coordinates between production, QC, and QA teams.

4. Accountability

The Capsule Manufacturing Supervisor is accountable for ensuring that adjustments to the gelatin composition are made in compliance with this SOP. The QA Manager is responsible for verifying the adjustments and reviewing the final product for compliance with quality standards.

5. Procedure

5.1 Identifying Seasonal Variations

To determine the need for adjusting gelatin composition, monitor the environmental conditions and identify any seasonal variations that may affect the manufacturing process:

1. Monitor Temperature and Humidity
   1. Track temperature and humidity levels in the production area to identify seasonal fluctuations. Ensure that the production environment is within the ideal range for gelatin processing.
   2. Document these environmental conditions regularly in the Environmental Monitoring Log (Annexure-1).
2. Evaluate Gelatin Properties
   1. Regularly assess the properties of the gelatin, including its viscosity, moisture content, and solubility, to determine if seasonal variations are affecting the material.
   2. Record observations in the Gelatin Properties Log (Annexure-2) to track trends over time.

5.2 Adjusting Gelatin Composition

Once seasonal variations have been identified, adjust the gelatin composition accordingly to maintain product quality:

1. Adjust Gelatin Concentration
   1. Increase or decrease the gelatin concentration as needed based on temperature and humidity. Higher humidity may require reducing the gelatin concentration to maintain consistency, while lower humidity may require an increase.
   2. Consult with the R&D or formulation team to determine the ideal concentration for the current environmental conditions.
2. Modify Additives
   1. Adjust the quantity of plasticizers, stabilizers, or other additives to compensate for changes in gelatin properties caused by seasonal changes.
   2. Ensure that the adjusted additives do not affect the final capsule’s quality or stability.
3. Monitor Gelatin Melting Point
   1. Check the melting point of the gelatin regularly during seasonal transitions, as changes in temperature may affect the gelatin’s behavior during encapsulation.
   2. Adjust the encapsulation temperature if necessary to ensure proper sealing of the capsules.

5.3 Conducting Quality Control Tests

After adjusting the gelatin composition, conduct the necessary quality control tests to verify that the adjustments have not negatively impacted the quality of the capsules:

1. Gelatin Testing
   1. Perform tests on the gelatin to ensure that it meets the required viscosity, solubility, and gel strength. This ensures that the gelatin will perform properly during capsule filling and sealing.
   2. Document test results in the Gelatin Quality Control Log (Annexure-3).
2. Capsule Testing
   1. Conduct tests on filled capsules to ensure that they meet the necessary specifications for weight, size, fill volume, and sealing integrity.
   2. If the capsules do not meet specifications, revisit the adjustments to the gelatin composition and make further refinements.

5.4 Monitoring Production

Monitor the production process to ensure that the adjusted gelatin composition is functioning as intended:

1. Observe Gelatin Flow
   1. Monitor the flow of the gelatin during capsule filling to ensure smooth processing without clogging or irregular filling.
   2. Document any irregularities in the Gelatin Flow Log (Annexure-4) and adjust the composition as needed to maintain optimal flow.
2. Monitor Capsule Sealing
   1. Check the capsule sealing process to ensure that the adjusted gelatin composition provides a strong and consistent seal. This is especially important during colder weather when gelatin may become more brittle.

5.5 Final Approval and Release

Once the gelatin composition adjustments have been made and the production process is running smoothly, proceed with the following steps:

1. QA Review
   1. The QA team should review all records, including quality control tests, batch records, and adjustments made to the gelatin composition, to ensure compliance with the required standards.
2. Approval for Production
   1. If the adjusted gelatin composition is verified to meet the required specifications, approve the batch for continued production and packaging.
