Description
技术领域
本发明提供了一种用于饲料的乳化油及其生产方法。
背景技术
由于生产性能的不断提高，畜禽对日粮养分浓度尤其是日粮能量浓度的要求愈来愈高。用常规的饲料原料难以配制出高能量饲料，而且常规饲料常常缺乏必需脂肪酸，其中的脂肪酸的组成也不平衡，易对动物生长造成影响。鉴于这些原因，近几年来，油脂作为能量饲料在畜禽日粮中的应用愈来愈受到重视。目前，饲料行业使用的油脂多为单一油脂，例如毛豆油、棕榈油或者猪油等。但单一油脂中的脂肪酸比例不平衡，存在木桶理论的短板效应。而且单一油脂中没有相应的乳化剂，动物采食日粮中的脂肪后，必须首先经消化道的机械运动和胆盐、磷脂的乳化作用，胰脂肪水解酶才能发挥作用，其主要原因是动物体内胰脂肪水解酶只在油与水界面起作用。这些原因都会造成油脂的消化吸收利用率偏低，影响到动物的正常生长及饲喂效果，降低养殖的综合经济效益。
发明内容
本发明所要解决的技术问题是，提供一种饲料用混合乳化油及其生产方法，这种混合乳化油具有良好的水溶性，以提高油脂吸收利用率，提高生产性能和饲料报酬。
本发明是这样实现的，一种饲料用混合乳化油，所述的混合乳化油的原料配比为，
玉米油 10-25重量份
豆油 10-25重量份
椰子油 10-20重量份
棕榈油 5-10重量份
花生油 5-10重量份
米糠油 10-20重量份
棉籽油 10-20重量份
羟基化改性大豆磷脂 10-35重量份。
一种饲料用混合乳化油的生产方法，在组成混合乳化油的原料中，将除羟基化改性大豆磷脂外的其它7种原料泵入反应釜，在搅拌下用蒸汽盘管间接加热，温度升至50-60℃时，加入羟基化改性大豆磷脂，搅拌均匀后，在原料温度升至55-65℃时，用泵将原料打入60目管道过滤器过滤，再用高乳化剪切机进行高速剪切一遍，然后用高压均质机在20-25Mpa压力下均质处理一遍，然后冷却至室温，制成混合乳化油。
这种饲料用混合乳化油，与目前饲料行业使用的单一油脂相比具有多种饲喂优点，用羟基化改性大豆磷脂作为生物乳化剂，具有良好的水溶性，更适合动物特别是幼畜肠道生理特点，产品中富含大量中短链脂肪酸，在小肠中直接吸收入血液，脂肪乳化后有效能值更高，乳糜微粒经高速剪切和高压均质直径更小(乳化油的微粒直径仅为2微米，而一般油脂微粒直径为20微米)，更利于动物吸收；产品中所含饱和脂肪酸与不饱和脂肪酸比例平衡，长、中、短链脂肪酸比例适宜，可明显提高生产性能和饲料报酬，降低养殖成本，提高综合经济效益，是目前饲料行业用油的良好替代品。
具体实施方式
下面进一步说明本发明。
在本发明之混合乳化油的生产方法中，将原料放入反应釜中、在搅拌下用蒸汽盘管间接加热时，采用60rpm转速搅拌，反应釜及管线采用不锈钢材质；在所述的高速剪切过程中，选用上海索维机电设备有限公司的SB415/1/6管线式高剪切分散乳化机，在2900rpm转速下剪切；均质处理采用廊坊通用机械公司JJ-1/40A均质机，均质处理时温度控制在55-65℃。
由于高乳化剪切机、高压均质机均为管式结构，因此，所述的用高乳化剪切机进行高速剪切一遍，然后用高压均质机在20-25Mpa压力下均质处理一遍，是指将物料分别从高乳化剪切机、高压均质机的进端送入设备内、处理后从出端排出的一个过程，即物料分别从各设备内走一遍的过程。
所采用的羟基化改性大豆磷脂由市售大豆浓缩磷脂经改性而制成。改性时，将大豆浓缩磷脂与羟基化试剂在一定条件下反应，从而在磷脂中的不饱和脂肪酸的碳链上加上羟基，明显改善磷脂的亲水性能。这种改性方法为现有技术，不再详述。
实施例1
称取玉米油20kg、豆油25kg、椰子油15kg、棕榈油8kg、花生油9kg、米糠油10kg、棉籽油20kg、羟基化改性大豆磷脂30kg。将除羟基化改性大豆磷脂外的7种原料泵入反应釜，在搅拌下用蒸汽盘管间接加热，温度升至55℃时，加入羟基化改性大豆磷脂，搅拌均匀后，在原料温度升至60℃时，用泵将原料打入60目管道过滤器过滤，再用高乳化剪切机进行高速剪切，然后用高压均质机在25Mpa压力、60℃温度下均质处理，然后冷却至室温，制成混合乳化油.
实施例2
称取玉米油25kg、豆油20kg、椰子油10kg、棕榈油6kg、花生油10kg、米糠油15kg、棉籽油15kg、羟基化改性大豆磷脂25kg。生产方法同实施例1。
实施例3
称取玉米油25kg、豆油25kg、椰子油20kg、棕榈油10kg、花生油10kg、米糠油20kg、棉籽油20kg、羟基化改性大豆磷脂35kg。生产方法同实施例1。
以下是以SN/T0801-1999、GB/T 17376-17377为参考检验依据，对本发明之混合乳化油进行检验的结果。
粗脂肪 98.3％
磷脂 31.2％
水分 0.10％
游离脂肪酸 7.54％
酸价 18.12
维生素E 2.06mg/100g
消化能 8645Kcal/Kg
代谢能 8232Kcal/Kg
在混合乳化油中，脂肪酸的含量组成如下。
1:0(豆蔻酸) 0.29％
1:0(棕榈酸) 23.21％
1:1(棕榈油酸) 0.11％
1:0(硬脂酸) 4.18％
