Granulometric Parameters Determination of the Caviar-Hawk Complex as a Dispersed System for the Fractionated Lecithin Technology Implementation

Abstract

For the functional food product manufacture a man can use secondary raw materials, the caviar–hawk complex, particularly. The main technological operations in the lecithin–containing substances production include its extraction processes from the initial caviar raw materials and raffinate obtained after the first stage of selective extraction. The operation mechanism requires a comprehensive study of the granulometric composition of raw materials. It was the research aim. A man assessed the granulometric composition of the caviar–hawk complex by visual analysis of its micrographs. The dispersion analysis demonstrated that the studied raw materials of all the analyzed species ranked as a small caviar, which is typical for ordinary fish objects. The thesis contains schematic elementary particle illustrations of fresh and dry caviar of carp, catfish, pike perch; presents dispersed equivalent sizes and shrinkage values of the research objects. Preliminary caviar grinding during conservation is impractical. Although this procedure leads to the mass transfer process intensification, since a man provides the analyzed caviar for using not only to obtain fractionated lecithin and protein texturate, but also as raw materials for enterprises. Staged experiments confirmed that an increase in the mass transfer rate, including the process of extracting target components from crushed caviar raw materials, was insignificant compared with the cost of additional grinding and loss of native caviar properties. The caviar under study is a finely dispersed product. Its additional grinding gives an insignificant effect.
