摘　　要：为生产高品质的一级大豆油,以大豆原油为原料,采取深度酶法脱胶、预复脱色、填料塔和板式塔脱臭、双捕集器捕集工艺生产一级大豆油。对于磷含量600~800 mg/kg的大豆原油,采用磷脂酶C(PLC)、磷脂酶A_(1)(PLA_(1))/磷脂酶A_(2)(PLA_(2))脱胶,选用低酸性活性白土脱色,先进填料塔脱酸,再进8层板式塔脱除微量组分,脱臭条件为温度230~240℃(可调)、真空度100~150 Pa、时间100 min(可调),采取双捕集器分别捕集维生素E含量10%~12%、酸值(KOH)40~50 mg/g和维生素E含量低于1%、酸值(KOH)130~140 mg/g的馏出物。在该工艺条件下,一级大豆油3-氯丙醇酯含量678.9μg/kg,2-氯丙醇酯含量310.3μg/kg,缩水甘油酯含量860μg/kg,反式脂肪酸含量0.886%,精炼得率提高2%左右。In order to produce high-quality first-grade soybean oil,with crude soybean oil as raw material,first-grade soybean oil was produced using deep enzymatic degumming,pre-decolorization,packed tower and plate tower deodorization,and double catchers processes.For crude soybean oil with phosphorus content of 600-800 mg/kg,PLC,PLA_(1)/PLA_(2)were used for degumming,low acidic active clay was used for decolorization,packed tower was used for deacidification,and then an 8-layer plate tower was used for deodorizing microcomponent and the deodorization conditions were temperature 230-240℃(adjustable),vacuum degree 100-150 Pa,and time 100 min(adjustable),and double catchers were used to capture distillates with VE content 10%-12%and acid value 40-50 mgKOH/g,and VE content less than 1%and acid value 130-140 mgKOH/g.Using this process,the contents of 3-chloropropanol ester,2-chloropropanol ester,glycidyl ester and trans fatty acid in first-grade soybean oil were 678.9,310.3,860μg/kg and 0.886%,respectively,and the refining yield increased by about 2%.
