Fat crystallization of blends of palm oil and anhydrous milk fat: A comparison between static and dynamic-crystallization

Food Research International, 2020
The application of dynamic-crystallization (a combination of shear with rapid cooling) often plays an important role in the production of industrial fat-based products such as shortenings/margarines but has been rarely reported. In this study, three blends of palm oil (PO) with anhydrous milk fat (AMF) (0, 25 and 50% AMF, w/w) were rapidly crystallized

Influence of shear on fat crystallization

Food Research International, 2016
Abstract Processing conditions greatly impact fat crystallization kinetics and growth mechanisms. Recently, there has been increased interest in elucidating the role of shear on fat crystallization. This review provides an overview of fat crystallization under static conditions followed by a summary of the current body of work pertaining to the ...

Nanostructured Fat Crystal Systems

Annual Review of Food Science and Technology, 2015
A new understanding of the nature and organization of fat crystalline supramolecular structure, in particular at the nanoscale, has arisen in the past three years. These new findings have helped establish that the first step in the formation of a triacylglycerol network is the creation of nanocrystalline platelets that aggregate into polycrystalline ...

Colloidal networks of fat crystals

Advances in Colloid and Interface Science, 2019
The following paper traces the development of the study of colloidal networks of fat crystals. The work starts with traditional pre-fractal particle network models of fat crystal networks. Due to its central importance in the study of colloidal networks of fat crystals (and other colloidal aggregates), a short exposition of fractal geometry is provided.

The Fractal Nature of Fat Crystal Networks

Colloids and Surfaces, 1992
Glycerol tristearate aggregates in olive oil are shown to have a fractal structure. The fractal dimension, is deduced from light scattering experiments, is d = 1.7, which is in line with predictions of recently developed aggregation models. The fractal dimension increases with time to d = 2.0, indicating that the aggregate structure becomes more ...

Thermodynamic and kinetic aspects of fat crystallization

Advances in Colloid and Interface Science, 2006
Naturally occurring fats are multi-component mixtures of triacylglycerols (TAGs), which are triesters of fatty acids with glycerol, and of which there are many chemically distinct compounds. Due to the importance of fats to the food and consumer products industries, fat crystallization has been studied for many years and many intricate features of TAG ...
