drying, is one of the important postharvest processes of medicinal plants with an important role played in quality and quantity of the drugs. in this research, in order to study the effect of growing conditions and different drying methods on drying time, essential oil content, color characteristics and microbial load of dracocephalum moldavica, a factorial experiment in randomized complete blo...

Roses, both fresh and dried, often appear during festive occasions. However, roses do not last long, dried flowers are marinated with environmentally unfriendly chemicals. This paper proposes the procedure experiment of drying by freeze-drying method. After proposed method, results show that rose color changes very slightly but still retains its natural, eye-catching, friendly appearance.

objective: the main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. methods: drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [hg], infrared radiation at power levels of 100, 150 and 200 w in the three repetition. resu...

A five level four factors central composite rotatable design under response surface methodology was used to optimize process conditions of the foam mat drying process i.e. egg albumen (0%-12%), methyl cellulose (0.1%-0.5%), drying bed thickness (3-7 mm) and drying temperature (55-75°C) to develop grape bar with final moisture content of 14%±1% (dry-base). Contour and response graphs were genera...
