Drying Spirulina with Foam Mat Drying at Medium Temperature

Lyophilizing Foot-and Mouth Disease Virus at Low Drying Temperature

Characteristics of selected functional properties of apple powders obtained by the foam-mat drying method

Foam-mat drying is an alternative method which enables the removal of water from high-sugar content juices and purees that are difficult to dry. The aim of this study was to investigate the effect of different foam-mat drying methods on some physical properties and aroma of apple puree powder. Apple puree was foamed with the addition of foaming agents. Foamed puree was dried as a layer using di...

High Temperature Walnut Drying

On farm walnut drying is often a major bottle neck during the start of walnut harvest. The recommended maximum drying air temperature for English walnuts is 110 of. This limit is based on tests by university personnel during the introduction of heated air drying (Batchelor, 1924) which demonstrated that long term exposure to temperatures higher that 110°F caused walnuts to turn rancid. This pro...

Production of Green Banana Powder Using Foam-Mat Drying Method: Effects of Ovalbumin Concentration on Drying Kinetics and Physicochemical Properties of the Product

Background and Objectives: Drying, one of the traditional food preservation technique, is a complex process defined as a simultaneous heat and mass transfer steps under transient conditions, which leads to significant changes in physicochemical properties of the foodstuffs. The objective of the present study was to assess effects of ovalbumin concentration (as a foaming agent) at three levels o...

Freeze-drying above room temperature.

This study investigates the use of solid, organic compounds to lyophilize drugs without conventional freeze-drying equipment. The aim of the investigation is to find a pharmaceutically acceptable solvent or solvent combination that is appropriate for freeze-drying on the basis of its ability to (1) solubilize hydrophobic drugs, (2) provide a stable environment for water-sensitive compounds, (3)...
