San Francisco

The Dairy Ingredients Symposium is a great opportunity to access comprehensive new technical and marketing information on dairy ingredients.

Presentations will cover topics such as:

• Global marketing for dairy ingredients
• Trends in latest dairy ingredient processing
• Safety of dairy ingredients
• Understanding and improving dairy ingredients functionality
• Perspectives on food industry needs for dairy ingredients
• and more . . .

Jakob Svendsen, GEA Process Specialist, will discuss "Freeze drying of heat sensitive materials to maintain bioactivity and potential applications for high value dairy ingredients"

Network with attendees from the dairy ingredient community, including professionals from food and beverage manufactures and suppliers, academics and government.

Abstract for Freeze Dying Presentation

When drying a heat sensitive product, freeze drying is the preferred method. Freeze drying is the only method where both gentle drying and low water activity can be obtained at the same time.

There will be a short introduction to the freezing and freeze drying processes in general and the GEA Niro freeze drying technology in particular. Here the focus here will be on condenser, product trays and radiation versus conduction and continuous versus batch dryers.

The freeze drying process will be compared with alternative drying technologies both in theory and in practice with analyses of dried products verifying that freeze drying is better than other drying methods in regards to product temperature, obtainable water activity and biological activity.

These results are from tests with freeze drying of probiotics where freeze drying preserves the biological activity and freeze drying of material containing aroma where it preserves the aroma.
