The final product quality depends
strongly on the properties ofthe raw materials as well as theprocessing parameters. You canmeasure the cohesion strengthwith an MCR Evolution rheometerfor powder rheology to find out
the flowability of the powder.
Employing this methodology, youwill know whether excess metal
powder from past production
is still viable or requires
the adaption of processing
parameters. In this way you cancalculate how much new powder
you have to add to make thepowder usable for high-quality
end products.

Many powders used in foodproducts can appear withmultiple polymorphs (crystalstructures) which can affectproperties such as the texture,flavor, mouthfeel, and stability of
the final food products. If a foodpowder contains impurities or thedesired polymorph is unstable,
this can lead to problems during
processing or to low-quality
products. Characterizing thecrystalline phases present
in a sample via XRD allows
optimization of these properties
to ensure the highest quality canbe obtained in terms of texture,
taste, and stability.

XRDynamic 500 powder X-ray diffractometer

What doesthat mean foryour process?

Knowing and controlling the powder properties that count is essential for smoothprocessing at maximum efficiency along with high-quality output. The powder cells
from Anton Paar give you the necessary tools to understand your powder during all
application stages.

In-depth understanding of the crystalline phases and crystallite size in food powders is crucial to be able to control the quality,flavor, and texture of final food products. With XRD measurements using XRDynamic 500, you can optimize each step of theprocess, from raw ingredients all the way to the finished products, to ensure the highest quality.

Laser diffraction is used tocharacterize the particle size
(typically micron size or above) oflarger food powders such as flour,coffee, or milk powders. It is aneasy, quick, and highly reproducible
method for checking the quality andprocessing behavior. Dynamic lightscattering enables the optimizationof formulation instructions andnutrient content for smaller
particles (typically nanometer size)in emulsions. For example, the fat
droplets’ size strongly influences
the texture, mouthfeel, and flow
behavior of milk. Additionally, asuspension’s stability is triggered by
the zeta potential (determined withelectrophoretic light scattering.

Food formulation, manufacturing,and packaging processes involving
both powder and fragmentary forms
require batch-to-batch consistency
to ensure excellent expected texture
and taste in the final product.

Autotap and Ultrapyc 5000

What doesthat mean foryour process?

Knowing and controlling the particle size of powders and dispersions is key to understanding theimportant characteristics – such as stability – of raw materials as well as final food products. The
wide size range covered by Anton Paar instruments enables you to investigate these properties
for many common food products and to improve, produce, and deliver your food products withconsistently high quality.

The Autotap solid density analyzer provides a definitive measure of compressibility to help inform intelligent packaging decisions
such as container size and shape, as well as the amount of food product shipped.
