Quality analysis of ultrasonically dried strawberry and comparison to conventional drying methods
Conventional, hot air drying is one of the most commonly used drying methods in the food industry for its simplicity, high productivity, and low capital cost. However, hot air drying has many limitations surrounding energy requirements, processing efficiency, and costs coupled with significant food …

Practical drying techniques for yellow-poplar S-D-R flitches
… the stress relaxation caused by high-temperature drying. Implementation of this S-D-R process in the Appalachian region has been limited as few mills in this area have this drying capability. The purpose of this study was to investigate the effectiveness of high-temperature and steaming treatments …

A novel approach to control stored sorghum beetle Tribolium castaneum (Coleoptera: Tenebrionidae) in small-scale farmers’ storerooms in Kebbi- Nigeria
… in plant species they collected and their plant-drying methods. Chemical analysis showed plant species and drying methods affected repellency; cultivated O. basilicum had higher repellent compound content and repelled more beetles (0.88±0.015) than O. africanum (0.62±0.020, p<0.001), and …

Development of All-Natural, Protein-Rich Snacks from imperfect Fruits and Vegetables
… often wasted due to spoilage and imperfections. Drying can extend the shelf life of produce and hide imperfections.Conventional drying methods like spray drying have high energy requirements and waste a portion of each fruit. Foam Mat Drying (FMD) has garnered renewed interest for the development …

Combined microwave - convection drying and textural characteristics of beef jerky
… and nutritional value. The current processing methods such as smoke house and home dehydrators take 6-10 h. Increasing market for this shelf-stable meat product increases the need for alternate efficient processing method. Also, this meat snack market depends on its textural characteristics …

Full-Season and Double-Crop Soybean Response to Potassium Fertilizer
… soil K concentrations when alternative soil drying methods were compared to air-dry methods. However, differences were not consistent and no single method was superior for these soils. More data is needed for double-crop soybean systems due to lack of response and lack of low soil test K …

Effects of pre and post-harvest treatments on the phenolic compounds and antioxidant activity of different onion varieties
… and post-harvest (processing and storage) methods. In order to achieve this, several experiments have been designed and carried out among different onion varieties, particularly between organic and conventional ones. The first experimental chapter aimed to compare the total phenolic …

Biodegradable polyanhydrides as drug delivery systems
… double emulsion solvent evaporation and spray drying methods. The characterisation of the microspheres, morphology, particle size, and drug loading, was studied. The in vitro hydrolytic degradation of polymers and blank microspheres was monitored using IR, GPC, and DSC. In vitro drug release …

Morphology-Property Relationships in Semicrystalline Aerogels of Poly(ether ether ketone)
… PEEK/4CP gels. Solvent removal utilized freeze-drying (sublimation) methods or supercritical CO2 drying methods. Varying the weight fraction of PEEK dissolved in solution determined PEEK aerogel density. Mechanical properties (in compression) were shown to improve with increasing density, …

CHICKPEA AQUAFABA AS AN EMULSIFIER IN FOOD-OIL SYSTEMS
… of optimum conditions for preparing AQ, five drying methods (freeze drying, spray drying, oven drying, rotary evaporation drying, and vacuum drying) were compared. Dried AQ was rehydrated with distilled water, and its emulsion capacity and stability were measured. AQ from CDC Leader had the …

Factors affecting drug distribution in granules.
… be further enhanced by solute migration during drying. Thus the peak drug concentration was obtained in the intermediate sized granules. For an appreciably high R value as in sodium salicylate/lactose formulation, a snow-balllng action was envisaged to counteract the massing action to a certain …

The Effect of Hydration on Enzyme Activity and Dynamics
… of water molecules bound to the protein after drying, using a modification of the method of Dolman et al. (1997). Testing different drying methods, we have been able to determine a level of hydration as low as 2 moles of water per mole of protein (equivalent to 0.0006 h in the case of pig liver …

Synthese und Charakterisierung von ferroelektrischen Xerogelen
… liquid in the pores can be removed by special drying methods yielding so called xerogels or aerogels. In this research a focus was set on the synthesis of LiTaO3, LiNbO3 and KNbO3 using lithium-, tantalum,- niobium,- and potassiumethoxide as starting materials. The wet gels are dried at …
