an excellent method for preserving pharmaceuticals. The drying process of freeze drying consists of two steps‚ Primary Drying and Secondary Drying. The bulk of water removed from the product during freeze drying is via sublimation of all of the free ice crystals and organic solvents during the primary drying step which is a slow process conducted at cooler temperatures‚ safely below the product’s critical temperature. In secondary drying‚ the water molecules that are bound to the SLN were removed

alternative to prevent instability in these cases[23‚24‚30]. Given that freeze-dried kits for radiodiagnosis are reported as an easy‚ fast‚ safe and reproducible way to obtain radiopharmaceuticals‚ it has been seen as a safe and effective alternative to prepare the PM-DTPA/PTX formulation[22‚31‚32]. However‚ considering that a lyophilization process involves conditions of stress‚ such as freezing and removal of water[33‚34]‚ and freeze-dried kits should be stable for long period of storage‚ a detailed

The aim of this research study was to develop process technology for a probiotic cereal bar by microencapsulating probiotics using the method of freeze drying and evaluating the viability of encapsulated probiotics in a cereal bar. A cereal mixture comprising of corn flakes‚ oat flakes‚ wheat bran were used to prepare cereal bar. The probiotic strains Lactobacillus casei (MTCC 1423)‚

food technology Introduction Drying is one of the most ancient methods of preserving foods; this method is still very popular and is used for drying fruits‚ beef (jerky)‚ fish‚ evaporated milk and much more. This method removes the moisture content of food to restrict microbial activity. The main methods of drying include sun drying‚ spray drying‚ dehydration and freeze drying. In this report it will discuss the process of sun drying for dried apricots and the techniques used

During the data collection procedure‚ there were potential limitations that could possibly affect the validity of the data collected and the conclusions that could be drawn from my investigation. The method optimisation study was based on trehalose‚ however‚ in an ideal world where no time restraints are present; the reconstitution study could be performed for each of the cryoprotectants to identify the most suitable method for each. This would then take into account the various differences that

Carbohydrates are macromolecules whose basic units are called monosaccharides (or simple sugars). These simple sugars are polyhydroxy aldehydes (aldoses) or ketones (ketoses)‚ depending on the chemical nature of their carbonyl group‚ containing at least three carbon atoms. The smallest monosaccharides with only three carbon atoms are collectively known as trioses; while those with four‚ five‚ six‚ and so on carbon atoms are called tetroses‚ pentoses‚ hexoses and so on‚ respectively. Carbohydrates

Crude drug A crude drug is any naturally occurring‚ unrefined substance derived from organic or inorganic sources such as plant‚ animal‚ bacteria‚ organs or whole organisms intended for use in the diagnosis‚ cure‚ mitigation‚ treatment‚ or prevention of disease in man or other animals. Crude drugs are unrefined medications in their raw or natural forms. Prior to the 1950s‚ every pharmacy student learned about crude drugs in pharmacognosy class. Pharmacognosy is the study of the proper horticulture

Weathering Process Physical Weathering Processes Freeze Thaw (Frost Shattering) Temperatures need to fluctuate above and below freezing. When the temperature drops below 0 degrees‚ water collected in rock cracks freezes and expands. When temperatures rise again the ice melts. Pressure created by expansion results in progressive weakening of the rock. At high altitudes frost-shattered material forms scree slopes. Heating & Cooling Thermal expansion & contraction of rock in response

dehydration. Usually‚ foods‚ which are concentrated‚ remain in the liquid state; while drying produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum concentration for freeze concentration is more than 50 Brix. Membrane concentration can be used for separating components
