Abstract
Numerous technologies are available for particle analysis,
such as laser diffraction, laser in-line particle size analysis,
acoustic attenuation spectroscopy etc. However, in many
situations, particle size analysis needs only to be conducted in
single-type research, negating the purchase of high cost
equipment. Microscopy assisted photography can be used
followed by the analysis of the photo in ImageJ program in this
case. It has been known seaweeds possess a high nutritional
profile and can partially replace some ingredients such as salt.
In represented method we describe an analytical tool for food
particle size diameter analysis and probability distribution
validated using four different seaweed separates (2360 to 355
µm mesh sizes). This method is cheap and consists of an
ordinary digital camera (or cell phone camera), any microscope
(or cell phone lens) or digital micrometer (forlarge particles)
and open-sourced software – ImageJ. For seaweed sample
separates obtained from 212 to 180 µm sieve mesh sizes, only
microscopy equipped with a digital camera was employed. This
method can be applied for any other industry such as biological
samples, pharmaceutical etc., witha particular any range of
particles distribution depending on accuracy required and
camera lens resolution.
