A method has been developed for marking the pores in egg shells by immersing them in concentrated nitric acid for very short periods of time. This makes the pores easily visible under the microscope, and counting can then be done by a statistical method. Not only is the total number of ...
Fish eggs have a thick and mechanically tough shell, the chorion (vitelline envelope; Iwamatsu 1969). They possess a specialized opening, the micropyle on the chorion above the animal pole; the fertilizing sperm must swim through this hole to gain access to the egg surface (Hart and Donovan ...

(B) RARRES2 relative expression in the different parts of the oviduct of hens (infundibulum, magnum, isthmus, shell gland and vagina) quantified by RT-qPCR (n = 6). (C) Protein abundance of chemerin detected by western blotting within the infundibulum, magnum, isthmus, shell gland and...
To shorten the salting time, pretreatment of egg using acetic acid and protease may increase the porosity of shell, thereby allowing salt to penetrate into egg white and yolk. This developed process can be implemented at the industrial scale, in which the faster salting process can be achieved....
On addition of diluted sulfuric acid, which of the following gives rotten egg smell: a) HgS b) PbS c) NH4Br d) Na2S Properties of Acids: The main property of acids is that they release hydrogen ions when placed in an aqueous solution; this p...
calcining the powdered egg shell at 950 degCel and transforming the egg shell powder to calcium oxide; treating calcium oxide with concentrated nitric acid to form calcium nitrate followed by dilution with distilled water; adding to the calcium nitrate a (0.10M), Na 2 HPO 4 .12H 2 O in am...
Although the egg weight was not affected (P = 0.521) by the dietary supplements, the shell ratio, shell thickness, yolk index and Haugh units increased linearly with the increase in the dietary supplements of the GAA (P = 0.036, 0.001, 0.012 and 0.004, respectively). The liver MDA levels...
Egg-yolk type of catalysts can be prepared by leaching the shell of a homogeneously impregnated, reduced catalyst with nitric acid followed by neutralisation. Egg-white type of catalysts can be prepared by selective leaching of a reduced, egg-shell catalyst....
