The processability of a margarine or other edible spread fat blends and the properties of the resulting products are to a large extent determined by the crystallisation behaviour of the fat blend. Problems of delayed crystallisation are known in the art of margarine or other spread manufacture, in particular, it is common knowledge in margarine blend formulation that interesterification of fats quite often results in slower crystallising fat blends and often fat blends which are impractically or inconveniently slow to crystallise. We have now determined that the crystallisation of margarine fats from a supercooled melt can be accelerated by the use of a triglyceride having a trans fatty acid at the 2-position, preferably a 1,3-saturated-2-trans-unsaturated (FTF) tempering accelerator. These include, in particular the HTH TAGs where H is stearic or palmitic, and especially PEP.
人造奶油或其他可食用涂抹油脂混合物的可加工性以及所得产品的特性在很大程度上取决于混合物的结晶特性。在人造奶油或其他涂抹酱的制造工艺中,延迟结晶的问题是众所周知的,特别是在人造奶油混合配方中,脂肪的酯化通常会导致脂肪混合物的结晶速度减慢,而且通常脂肪混合物的结晶速度慢得不切实际或不方便。我们现在已经确定,通过使用在 2 位有反式脂肪酸的甘油三酯,最好是 1,3-饱和-2-反式不饱和(FTF)调质促进剂,可以加速人造奶油脂肪从过冷熔体中的结晶。这些甘油三酯尤其包括 HTH TAG(其中 H 为硬脂酸或棕榈酸),特别是 PEP。
