Establishing an optimal size for fat droplets in dairy emulsions such as milk, ice-cream and cream liqueurs is essential for commercial success. Emulsification to a smaller droplet size tends to improve product quality but increases manufacturing costs. In this article, Dr Sarennah Longworth-Cook, Product Technical Specialist at Malvern Instruments, looks at particle sizing techniques that can be helpful, focusing on the application of laser diffraction.
Key Points:
- The particle size of fat droplets in dairy emulsions such as milk, ice cream and cream liqueurs directly impacts their performance, perceived quality and commercial viability.
- Targeting a relative fine particle size distribution often helps to improve product characteristics but increases energy consumption during the emulsification process. Identifying an optimal particle size supports the cost-effective manufacture of high quality products.
- Laser diffraction and dynamic light scattering are both fast and efficient techniques for sizing dairy emulsions with laser diffraction offering the more optimal measurement range for many products.
