炼制条件对牛油中塑化剂及风味物质的影响Effects of refining conditions on plasticizers and flavor substances in tallow
为保障牛油的食用安全和风味品质,以被邻苯二甲酸二正丁酯(DBP)和邻苯二甲酸二(2-乙基)己酯(DEHP)污染的生牛脂为原料,对其进行炼制,考察炼制条件对牛油中DBP和DEHP含量的影响,采用电子鼻分析炼制条件对牛油风味的影响。结果表明:牛油中DBP、DEHP含量随炼制温度、炼制时间、炼制压力和加水量的变化表现出不同的变化规律,适宜炼制条件为炼制温度120~140 ℃、炼制时间10~15 min、炼制压力-0.02 MPa、加水量2 mL/100 g,在此条件下炼制的牛油DBP和DEHP含量较低且稳定;氮氧化合物、硫化物、萜类化合物、短链烷类、醇醚醛酮类化合物是牛油的主要风味成分。通过线性判别...
