摘要
选用0.025 MPa,0.04 MPa,0.05 MPa,0.06 MPa四种真空度,在45℃,60℃,75℃三种温度下对洋葱进行脱水处理,测定不同干制工艺条件下不同时期洋葱的重量,并进行复水比较试验.结果表明: 0. 05 MPa、60℃为洋葱真空干燥的最佳工艺条件.
Onion was treated by using vacuum drying under 0.025 MPa, 0.04 MPa, 0.05 MPa, 0.06MPa vacuum degree and 45 ℃,60℃,75℃ temperature, levels of fresh and dried onion were determined about weight. And rehydration tests were respectively done. The results show that the best vacuum drying technological condition is 0.05 MPa,60℃.
