The drying of pears allows their conservation due principally to the inhibition of microbial growth, making the dried pear a safe food for consumers. The knowledge of microbial flora, as well as some biochemical factors, is very important for ensuring the consumers health. In this study samples of pears of the variety S. Bartolomeu were dried under different systems: traditional open air sun dr...

a thin layer solar drying method was compared with a traditional method (sun drying) of paddy drying, with their effects on quality characteristics of two varieties of iranian rice (kamphiroozi and sazandegi) studied. solar drying process was conducted in a passive, mixed mode type solar dryer at about 50ºc for 90 minutes. in sun drying method this process took 8-10 hours at a mean temperature ...

We investigate the dynamics of fracture in drying films of colloidal silica. Water loss quenches the nanoparticle dispersions to form a liquid-saturated elastic network of particles that relieves drying-induced strain by cracking. These cracks display intriguing intermittent motion originating from the deformation of arrested crack tips and aging of the elastic network. The dynamics of a single...

Background: The post-harvesting process of medicinal plants such as drying operation and storage conditions has great influence on their quality and quantity of the active ingredients. Objective: The aim of this experiment was to investigate the effect of pre-drying operation and also storage conditions and duration on the essential oil content and composition of Thymus daenensis. Methods: A ...

Multistage heat pump drying of macadamia nut under modified atmosphere was studied to improve the drying process and quality of the nuts. Conditions of study included drying temperature of 40-60°C, using nitrogen and normal air as drying medium. Drying kinetics and quality of nuts (moisture content, aw, rancidity and colour) as well as energy consumption of all drying processes were examined. T...

In this paper, differences in porosity, compressive strength and tablet- forming ability of carbamazepine crystals agglomerated under similar condition, but subjected to different drying temperatures are reported. The agglomerates were prepared by spherical crystallization method and thereafter dried without agitation at different temperature. An increased drying temperature did not affect the ...
