Studies on Changes in Stored Shell Eggs. Part II

Identification of yeasts isolated from commercial shell eggs stored at refrigerated temperatures.

Yeasts and molds can grow on or in eggs, causing spoilage. Washed and unwashed eggs (treatments) were collected aseptically on three separate days (replications) from a commercial processing facility and stored for 10 weeks at 4 degrees C. Ten eggs from each treatment were sampled weekly (110 eggs per treatment per replication). Yeasts and molds were enumerated from external shell rinses by pla...

Studies on Shell Formation

Details of crystal growth in the calcitostracum of Crassostrea virginica have been studied with the purpose of analyzing the formation of the overlapping rows of oriented tabular crystals characteristic of this part of the shell. Crystal elongation, orientation, and dendritic growth suggest the presence of strong concentration gradients in a thin layer of solution in which crystallization occur...

Studies on the Standardisation of Curnas Part – Ii Talizadya Curna

Talisadya churna was prepared by pounding the individual ingredients in mortar and pestle and mixie. The Curna prepared by pounding the ingredients in mortar and pestle showed higher exhaustive extraction in hexane and solubility in alcohol. The Curna prepared by grinding the ingredients in mixie showed less acid insoluble content, high volatile matter, water soluble matter, and exhaustive extr...

Microbial contamination in inoculated shell eggs: II. Effects of layer strain and egg storage.

Three Ottawa control strains and a current commercial laying stock were reared and housed in the same environment. Eggs were collected at 5 different hen ages throughout the 2 production cycles of the flock. The eggs were inoculated with Salmonella Enteritidis (SE), Pseudomonas fluorescens (PF), a combination of the 2, or sterile buffered peptone water and stored up to 5 wk. After storage at ro...
