Food & Beverage

The size and shape of particles in our food not only affect the taste and texture, but also the nutritional characteristics and digestive properties. Additionally, the quality, processing and packaging of food during production is dependent on the size and shape of particles, bulk and tap density, and flow properties of ingredients.

Bioprocessing in the development or manufacturing of foods affects the micro-structure as well as the chemical and nutritional values of food. Particle size and characterization is essential in this process to obtain desired purity, quality and nutritional properties. 

One example of particle characterization in the food industry is its use in chocolate manufacturing. Manufacturers characterize their products by what they term as “Mouth Feel.” If the particle size of cocoa used to make the chocolate is too coarse, the product may feel gritty. If it is too fine, the product may feel sticky. Particle size also affects the level of bitterness when tasted.

Milk is a combination of oil and water. Oil and water are not miscible and thus form an emulsion. Particle size analysis can determine the droplet size of the oil emulsion. Zeta potential of the emulsion system can be used to predict stability of the milk on the store shelf. This can indicate the effectiveness of the homogenization process, improve the milk’s consistency and increase shelf-life stability.

After coffee is roasted, it is ground into different size ranges depending on its origin, flavor profile and brewing method. Particle size analysis of the ground coffee is performed for quality control to ensure each cup is consistent.
