• Osmotic drying: Moisture from the product is drawn out by a concentrated solution, such as sugar or salt.

7. How do you determine the optimal drying conditions for a specific product?

The optimal drying conditions for a specific product depend on factors such as:

• Product type and moisture content.
• Desired final moisture content.
• Drying equipment and capacity.
• Environmental conditions.

8. What quality control measures are implemented to ensure the quality of the dehydrated products?

Quality control measures for dehydrated products include:

• Raw material inspection.
• Process monitoring.
• Product testing.
• Packaging and storage.

9. How do you handle and store dehydrated products to maintain their quality and prevent spoilage?

Dehydrated products should be handled and stored properly to maintain their quality and prevent spoilage:

• Store in airtight containers to prevent moisture absorption.
• Keep in a cool, dry place away from direct sunlight.
• Use oxygen absorbers or vacuum packaging to remove excess oxygen.

10. What are the emerging trends and advancements in dehydration technology?

Emerging trends in dehydration technology include:

• Use of microwave and radio frequency drying.
• Development of more energy-efficient drying processes.
