Cinnamaldehyde is obtained from the cinnamon tree and is generally considered safe (GRAS).1
This active ingredient is a natural compound isolated from the stem bark of Cinnamomum Cassia. It
has been shown to have various effects such as antitumor, antifungal, cytotoxic and mutagenic.2
Cinnamaldehyde was developed as a food-grade antimicrobial agent because it has been shown to be
active against both gram-positive and gram-negative bacteria, including organisms of safety concern.3
Due to these advantages, cinnamaldehyde has great potential to be used as a natural antifungal agent
in the food industry. However, properties such as unpleasant odor, high volatility, easy water solubility,
and extreme instability under ambient conditions (temperature, light, oxygen) limit their direct
application in the food industry. Microencapsulation is an emerging technology that protects various
food ingredients or functional ingredients against various processing conditions by encapsulating them
in polymeric or non-polymeric materials and controlling their release under certain conditions.
The aim of this study is to use cinnamaldehyde as a food preservative by taking advantage of
its antifungal properties without changing the parameters of the food such as taste and smell. Two
different techniques were used as microencapsulation methods. Chitosan/gum arabic by complex
coacervation method; chitosan/soy protein polymers were used. Alginate microbeads were obtained
using the ionotropic gelation method. Antifungal studies of the microencapsulated cinnamaldehyde
obtained against Aspergillus flavus isolated from Tomato Paste were carried out and their activities
were compared. Isolated soy protein/chitosan complex coacervation was measured at 97.08 %
encapsulation efficiency (EE) and 45.30 % loading capacity (LC), MIC (minimal inhibitory concentration)
and MFC (minimal fungicidal concentration) were 187.5 ppm and 62.5 ppm, respectively.
