Effect of Turntable Rotation Rate on Drying Kinetics and Functional Properties of Lemon Peel during Microwave Drying
نویسندگان
چکیده
The aim of this study is to investigate the effect rotational rate turntable on drying kinetics lemon peels and some functional flow properties peel powders. Lemon were dried by microwave using different rates rotation (0, 6.5, 9.5, 12.5 rpm) at power levels (180W, 300W, 450W 600W), oven freeze-drying methods. Drying time was shortened 72- 95% compared drying. Microwave with provided 5.6-23.8% reduction in without rotation. Effect depended level. Page model lower SSE, RMSE, higher R2 values within 5 thin layer models. effective moisture diffusivity value, ranging between 1.7x10-8 m2 s -1 -7.6x10-8 -1, during activation energy ranged 21.3-22.7 W/g. bulk density, similar or water holding capacity oil retention freeze Freeze powder had lowest density due its porous structure. highest level caused density. At levels, influence more notable. technique can be used as alternative techniques obtain high quality if appropriate processing conditions are selected.

Evaluation of Drying Methods With Respect to Drying Kinetics and Mineral Contents of Dill and Parsley
Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (50oC) drying methods. Oven drying decreased the drying time approximately 50% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the su...
