The following are the general methods of food preservation:  application of heat, such as canning and preserving, pasteurization, evaporation, sun-drying, dehydration and smoking,  application of cold, as ill cold storage, refrigeration and freezing,  the use of chemical substances such...

Recently, carbon nanofibers have gained immense attention in research due to its tremendous application. Here, this work highlights a simple, cost effective and reliable method to develop carbon nanofibers (CNF) from biomass. The biomass used is bacterial cellulose (BC) synthesiSed using Acetobacter xylinus. CNF was developed by freeze drying of BC followed by pyrolysis at different temperature...

Spray drying is presently one of the most interesting technologies in the pharmaceutical industry. The process shows a remarkable capability in manipulating powder/particle attributes such as size, morphology, density and level of residual solvents. This flexibility led to its application in a variety of powder formulations and advanced solid forms: from very fine powders for inhalation to larg...

Zanthoxylum limonella (Dennst.) Alston. (Rutaceae) or Ma-khwaen is one of the medicinal plants in Thai traditional medicine. To investigate the pharmacognostic specifications and chemical constituents of Z. limonella fruits and seeds. Fruits and seeds of Z. limonella were collected from 15 sources throughout Thailand; then examined the pharmacognostic specification following WHO guideline of qu...

Pistachio as a strategic product has a particular position among Iranian productions and is one of the most important non-oil exports after carpet. In this study, after primary processing such as dehulling, washing, drying and roasting, pistachio nuts were packed in four different atmospheres including N2, CO2, vacuum and ambient air. Storage temperatures were 20 C and 40 C for a 12 month perio...

We have tried to microencapsulate β-carotene with curdlan of a thermogelation type polysaccharide. Microcapsules were prepared by utilizing reverse dispersion, in which salada oil was the continuous phase (O') and the curdlan water slurry (W) was the dispersed phase. β-carotene (O) as a core material was broken into fine oil droplets in the dispersed phase to form the (O/W) dispersion. The (O/W...

The application of biocatalysts in the transesterification process of triglycerides (TG) allows integrating the glycerol in the form of monoglyceride (MG), sharply increasing the yield and the environmental sustainability of the conventional biodiesel production process. This is known as Ecodiesel. To overcome the inconvenient of the high cost of the currently employed highly purified commercia...
