today special attention has been paid to the microbial quality of medicinal plants.one of the operations in order to maintain the quality of plants is drying which may also affect the quantity and quality of the essential oil. in order to evaluate drying process effect in peppermint,the experiment was conducted in randomized complete block design with 4 treatments and 3 replications. the treatm...

In this study, Kageneckia oblonga leaves were dried under different drying conditions and techniques [oven (NC), vacuum (VNC), convective (FC), microwave-assisted (MWFC)]. Thus, the effect of temperature, vacuum, microwave on features K. was determined. Fick's second law used to calculate effective moisture diffusivity that varied from 3.94 8.14 × 10 −11 m 2 /s, 1.12 1.40 7.83 11.36 6.93 16.72 ...

Survival rates of Ascosphaera aggregata and Ascosphaera apis over the course of a year were tested using different storage treatments. For spores, the storage methods tested were freeze-drying and ultra-low temperatures, and for hyphae, freeze-drying, agar slants, and two methods of ultra-low temperatures. Spores of A. aggregata and A. apis stored well at -80 degrees C and after freeze-drying. ...

1 Purpose. To investigate pH and osmolality changes in the solutions stored in 2 contact lens cases, when different case rinsing and drying methods are used on 3 a daily basis. 4 Methods. Four multipurpose solutions (Opti-Free Express, Solo-Care Aqua, 5 Re-Nu Multiplus and Complete) and two hydrogen peroxide systems 6 (AOsept and Oxysept) were studied. Cases were filled with the solutions and 7...

The calculation of heat consumption is based on the First Law and it gives quantitative information about the energy used in drying. However, it does not pay any attention to the quality of the energy used in drying. To take into account the quality of the energy, attention must be paid to the Second Law, too. Especially in those cases where the energy used in drying may be converted to mechani...

Nanostructured silica based xerogels and aerogels are prepared by sol-gel technology, using methyltrimethoxysilane as precursor. The influence of the drying method and conditions on the microstructure of the obtained materials is investigated, since the drying stage has a critical influence on their porosity. Two types of drying methods were used: atmospheric pressure drying (evaporative), to p...

This study investigated the most appropriate drying method (sun drying, oven drying, or air drying) for mistletoe leaves obtained from almond tree. The phenolic constituents were characterized using high-performance liquid chromatography-diode array detector, while the inhibitory effect of the aqueous extracts of the leaves on angiotensin-I converting enzyme (ACE) was determined in vitro as als...
