## Abstract The functional and nutritional characterization of two isolates elaborated through cleaningβextraction processes, as well as that of a third isolate obtained by means of a chemical modification (alkaline heat treatment) from one of the former, was carried out. The first two isolates exh

β¦ Synopsis
Antarctic krill is considered to be a very promising source of food proteins and other biologically essential components, including microelements. In the present article the microelement composition of krill proteins obtained by alkaline extraction is studied. The studies showed that the ash content of the isolated krill proteins is rather constant and does not depend on the different lots of krill. It could be demonstrated that isolated krill proteins are a source of biologically essential microelements. The fluorine and heavy metal contents are within allowable limits and do not restrict the use in food production.

The optimum conditions were determined for the preparation of protein isolates from ground, defatted guava seed flour. The isolates were obtained by micellisation and isoelectric precipitation techniques. The isoelectric point of guava seed protein was found to be pH 4.5 with a protein solubility of
