The Effect of Fish Oil Concentration on the Microcoating Process with Coating Materials to Produce Microcapsules and to Investigate their Physicochemical Properties Using Wall Materials and Different Microcoating Methods

Abstract

Microcoating with coating materials is used to increase oil stability and control unpleasant taste and smell. The effect of fish oil concentration on the process of micro-coating with coating materials was investigated in order to emphasize the microcapsules and investigate their physicochemical properties using wall materials and different micro-coating methods. In order to check the physicochemical properties of the parameters and methods of measuring the moisture content, the total oil content, the surface oil content, the microcoating efficiency, the color and the morphology of the microcapsules are investigated using the research results. The results of the investigation of the physicochemical factors of the produced powders show that the coacervation method is also the most suitable microcoating method for fish oil. Microcoating with these materials and this method is able to produce powders with higher microcoating efficiency and lower surface oil content than other treatments. The results show that the microcapsules produced by the coacervation method are more spherical and larger than other treatments. The comparison of spray drying, freeze drying and coacervation and mixed mass methods confirms that wall composition, drying temperature, microcapsule morphology and process time are actually the most important factors that affect the stability of oily fish powder
