The aim of the present study was to compare two NaCl extraction methods of hen egg yolk phosvitin isolation, which differ in the use of organic solvents. The study was conducted on eggs from hens of Lohmann line and Green-leg breed, which were divided into 4 groups : I – eggs from Lohmann line fed without supplementation, II – eggs from Lohmann line fed with the addition of humokarbowit and humobentofet, III – eggs from Greenleg breed fed without supplementation, IV – eggs from Green-leg breed fed with the addition of humokarbowit and humobentofet. In the study, the yield of the phosvitin was examined and the following chemical components of yolk were analysed: dry matter, free fat and protein content. The results of the experiment showed that the breed of hens is responsible for yield of phosvitin isolation from hen egg yolk. Green-leg breed had the highest yield of phosvitin isolation in comparison to Lohmann line. The highest yield of phosvitin isolation was recorded in groups fed with addition of humokarbowit and humobentofet (II, IV). The type of used method of phosvitin isolation from hen egg yolk had no significant effect on the yield of the process.
