Special Issue Information

Dear Colleagues,

Understanding crystallization is increasingly important to design bioinspired nanocomposite materials and control the stability of biopolymer-based materials. In the category of polysaccharides, polymeric cellulose, as an example, has been a promising candidate to enhance mechanical properties in the composite materials. Aligning its crystallinity is believed to fabricate high-performance materials. In addition, several factors play roles in controlling the performance of such composite materials as morphology, degree of crystallinity, molecular weight. Different from cellulose, other polysaccharide, starch, undergoes phase transition from amorphous to crystalline structures upon moisture uptake, which is called as a retrograded starch. This mechanism is a time-dependent phenomenon, and it depends on relative humidity and temperature (storage conditions). The crystallization of starchy-based products is sometimes undesirable. However, a better understanding of the mechanisms of starch crystallization, including its kinetics, is crucial to develop such specific properties of interest as texture, adhesion, solubility through starch modification in the industrial processes. Like starch, another class of carbohydrate, lactose is also sensitive to changes during storage. In contrast to starchy foods, lactose crystallization is highly unwanted for food producers and end users because it significantly affects functional properties of food powders, such as powder wettability, powder flowability, color. Due to changes in the functional properties, crystallization of polysaccharides and carbohydrate should be inhibited when they are stored under the influence of extreme relative humidity and temperature by incorporating functional additives or encapsulating these biopolymer matrices.

The purpose of this special issue is to collect current perspectives and update results on the crystallization of polysaccharides (cellulose, mannan, chitin, starch) and carbohydrates (starch, lactose, maltose, trehalose), the impact of their crystalline structures in a broad spectrum of applications covering composites and foods, their crystallization kinetics as well as the potential strategies to control the crystallization. The topics include, but are not limited to, the following:

  • The self-assembly of polysaccharide nanocrystals and polysaccharide nanocrystals-based composites;
  • The factors affecting the alignment of polysaccharide nanocrystals;
  • Changes in the polysaccharide crystallinity through different modification approaches;
  • The kinetics of polysaccharides and carbohydrate crystallization at broad range of storage conditions;
  • The impact of carbohydrate crystallization on other macronutrients, protein and fat;
  • The impact of crystallization and crystals of polysaccharides and carbohydrate in emulsion;
  • The kinetics of carbohydrate crystallization at broad range of humidity;
  • The methods to quantify the surface area of polysaccharide and carbohydrate crystalline structures existing at the particle surface;
  • Strategy to delay or inhibit carbohydrate crystallization
