The invention discloses a preparation method of DHA and ARA emulsion. The steps are as follows: DHA oil agent and ARA oil agent are added into the agitator, the temperature rises to 65_72 degrees Celsius under the protection of nitrogen, the agitator works for 15 minutes, the agitator speed is 100_230 r/min, the emulsifier and auxiliary emulsifier are added to the agitator, the agitator works for 15 minutes, and the agitator speed is 150_320r/min. The product was added to the high shear emulsion pump, and the alkali solution was added to the high shear emulsion pump. The high shear emulsification pump was stirred at low speed, stirring time was 1 3H. The high shear emulsion pump was cut at high rotational speed, and the emulsion was added with deionized water at the same time. The turning point was found, and the emulsion was cooled to room temperature. The emulsifying agent and oil entrapping agent have overcome the shortcomings of the oil agent, and do not need spray drying to overcome the shortcomings of the powder and high temperature resistance. The emulsifier and the assistant emulsifier prevent the DHA and ARA emulsion from being stratified, and enhance the shelf life of the DHA and ARA emulsion.
【技术实现步骤摘要】
一种DHA和ARA乳化液的制备方法
本专利技术涉及乳化液
,具体为一种DHA和ARA乳化液的制备方法。
技术介绍
DHA学名二十二碳六烯酸,俗称脑黄金,一种含有22个碳原子和6个双键的直链脂肪酸,属于Omega-3不饱和脂肪酸家族中的重要成员。DHA是神经系统细胞生长及维持的一种主要元素,是大脑和视网膜的重要构成成分。对智力和视力发育至关重要。ARA学名二十碳四烯酸,又名花生四烯酸,含有四个碳-碳双键,一个碳-氧双键,属Omega-6族长链多元不饱和脂肪酸,在成人体内可以由必需脂肪酸——亚油酸转化而成,不属于必需脂肪酸,对大脑和神经系统发育有重要作用。目前各个奶粉企业大部分均采用湿法工艺,所使用的DHA和ARA有两种剂型,第一种剂型是粉剂,优点是经过乳化和包埋,稳定性好,便于贮存和运输。缺点是经过喷雾干燥变成粉末,部分未包埋好的粉剂表面油含量高,在高温条件下容易加速HA、ARA氧化,出现“鱼腥味”。第二种剂型是油剂,优点是未经过喷雾干燥工艺中高温处理。缺点是未经过乳化和包埋,直接添加到奶粉中,在货架期内受光照和氧气等因素影响,容易氧化。
