Methods and systems for production of low water activity fillings

A method and system for making a low-water activity filling, such as creme type fillings, is provided. The fillings advantageously can be used with rotary sandwiching machines without the need for a cooling tunnel downstream of the scraped-surface heat exchanger in the production line. The fillings produced herein comprise a fat component and sugar source, and the fat in the filling has the desired crystallinity. The process and system described herein unexpectedly achieve both a desired nucleation and crystallization rate and crystal structure, as well as the resulting increased filling firmness, in the fillings produced therewith. 本发明提供了种用于生产低水活度填充物(例如，奶油类填充物)的方法和系统。所述填充物可有利地与旋转式夹心机起使用，而不需要在生产线中的刮板表面式热交换器的下游设置冷却通道。本发明产生的填充物包含脂肪组分和糖源，并且填充物中的脂肪具有所需的结晶度。本发明所述的方法和系统出乎意料地获得了所需的成核速率、结晶速率和晶体结构，而且利用所述方法和系统产生的填充物的坚实度增加。
