Microwave vacuum drying has been investigated as promising potential for high-quality dried fruits. In this study, a batch microwave vacuum dryer was used to understand the effect of levels of microwave power on the drying characteristics and moisture content of grapes. Thompson seedless grapes were treated 1st for 30, 60, and 90 min at fixed levels of 500, 750, 1000, 1250, and 1500 W at a redu...

This article presents an investigation of the potential of spray and spouted bed technology for the production of dried extracts of Rosmarinus officinalis Linné, popularly known as rosemary. The extractive solution was characterized by loss on drying, extractable matter and total phenolic and flavonoid compounds (chemical markers). The product was characterized by determination of loss on dryin...

Despite of turmeric oleoresin having many advantages over ground turmeric roots, its sensitivity to light, heat and oxygen is a disadvantage. One approach to overcome this problem is microencapsulation. The objective of this work was to investigate the influence of different ratios of maltodextrin/gelatin used as wall materials, as well as the use of ultrasound during the emulsification step on...

In the pharmaceutical industry, the three most common granulation processes for solid dosage form production are wet granulation, dry granulation (roller compaction) and direct blending. Yet, despite being well-established techniques, each has its drawbacks. Moisture-activated dry granulation (MADG) was developed in response to the difficulties experienced with wet granulation, in terms of endp...

In 2008, the European Union Commission put forward a proposal for a new directive on renewable forms of energy. Each of the member states should increase its share of renewable energies in an effort to boost the total share of the EU from the current 8.5% to 20% by 2020. The level of renewable energy in Finland was 28.5% in 2005, and the national target share of renewable energy by 2020 is 38%....
