摘  要：
采用离心喷雾干燥、热风干燥、远红外干燥、真空冷冻干燥对安徽临泉产新鲜生姜进行干燥制粉,研究干燥制粉后的生姜粉的物理性质。结果表明:喷雾干燥的生姜粉容重较高,而得率、水合能力、吸油能力以及感官性能都是最差的;远红外干燥的生姜粉得率和容重最高,水合能力、吸油能力及感官性能较好;热风干燥的生姜粉水合能力最好,而得率、容重、吸油能力和感官性能都仅次于远红外干燥的姜粉;真空冷冻干燥的生姜粉得率和水合能力居中,容重最低,吸油能力和感官性能最好。

摘  要：
Using ginger in Anhui linquan as raw material,ginger powder was made by four drying methods: spray-drying,heated-air drying,far-infrared(FIR) drying and vacuum freeze drying.The physical properties of ginger powder was studied.The results show that ginger powder by spray-drying has high density,but the yield,hydratability,oil-absorbing ability and organoleptic quality are the lowest;the yield and density of ginger powder by FIR drying are the highest,hydratability,oil-absorbing ability and organoleptic quality are better;the hydratability of ginger powder by heated-air drying is the best, but the yield,density,oil-absorbing ability and organoleptic quality are inferior to FIR drying;the yield and hydratability of ginger powder by vacuum freeze drying are in the middle of the four drying methods,density is the lowest,oil-absorbing ability and organoleptic quality are the best.
