Abstract
The effects of ultrasonication and drying method on particle size and other product
characteristics of bio-calcium
powder from Asian sea bass (Lates calcarifer) backbone
were investigated. Ultrasonication was performed at different amplitudes (60%, 70%,
and 80%) for varying periods (15 and 30 min). Ultrasonication at higher amplitudes
for a longer time reduced the powder particle size more effectively (p < .05), but had
no impact on zeta potential (p > .05). The bio-calcium
powder ultrasonicated at 70%
amplitude for 15 min had the smallest particle size (3.38 μm) when compared to the
control (28.85 μm). When the ultrasonicated bio-calcium
was subjected to drying,
freeze-drying
produced powders with higher calcium solubility but lower whiteness
than hot air (tray) drying. The results suggest that the ultrasonication is a potential
suitable method to reduce the size of bio-calcium
powders, while the drying method
slightly affected the product characteristics. The bio-calcium
powder could serve as
a suitable functional ingredient for food fortification aimed at improving the calcium
bioavailability.
Particle size of bio-calcium
powder from fishbone could affect the mouth feel and
calcium solubility when used for food product fortification. This work showed that
ultrasonication could be used to obtain up to 10-fold
reduction in the particle size of
fishbone bio-calcium
powders, which promotes increased calcium solubility when
subjected to simulated gastrointestinal tract digestion. Few differences in characteristics
of the bio-calcium
powder were observed for freeze-dried
and hot air-dried
samples. Thus, an economical, safe, and fast process can be implemented for the
production of small particle size bio-calcium
powder from fishbone.
