Comparison of Physicochemical and Functional Properties of Chicken and Duck Egg Albumens Rev. Bras. Ciênc. Avic.
Chaiyasit,W; Brannan,RG; Chareonsuk,D; Chanasattru,W.
ABSTRACT The aim of this research was to investigate the physicochemical and functional properties of fresh and pasteurized chicken and duck egg albumens. The results showed that pasteurization of both chicken and duck albumens significantly decreased (p≤0.05) viscosity, but had no impact (p>0.05) on pH or free sulfhydryl groups. Chicken albumen was shown to have higher (p≤0.05) foam expansion, but lower (p≤0.05) foam stability than duck albumen. Pasteurization decreased (p≤0.05) the foam expansion of both albumens while decreasing (p≤0.05) the foam stability only of duck albumen. Investigation of the gel properties showed that duck albumen has greater hardness and lower expressible water (p≤0.05) than chicken albumen. Pasteurization increased the...

Influence of Prolonged Salting on the Physicochemical Properties of Duck Egg White BABT
Venkatachalam,Karthikeyan.
ABSTRACT Salted duck eggs are unique among the important authentic foods of Thailand. They are mainly produced in Chaiya district, Surat Thani province, in the southern part of Thailand. The egg whites of salted duck eggs are normally unusable due to heavily salty taste upon prolonged storage. The present study was aimed to examine the foaming characteristics of egg white after being cured for a prolonged period (30 days). At 5-day intervals the egg whites were measured for salt, moisture, water activity, hydrophobicity, pH, zeta potential, particle size, SH groups, surface tension and foaming properties (index of whipping, foam durability, specific density, overrun, air phase and yield stress). The results showed that prolonged curing significantly...

Internal quality of laying hen eggs fed on protease at different storage and stocking conditions Animal Sciences
Suckeveris, Diana; Muñoz, Julian Andres; Demuner, Leandro Félix; Caetano, Vinícius Camargo; Faria Filho, Daniel Emydgio de; Faria, Douglas Emygdio de.
Effects on diets with reduction of crude protein and methionine + cystine (RCP) and protease supplementation (PRO) for laying hens at different ages and their influence on the internal quality of eggs at different conditions (STO) and storage times (TM) are evaluated. Four hundred and twenty eggs from commercial Hy-Line W36 laying hens collected at 32, 44 and 58 weeks of age were used. Experimental design was completely randomized in a factorial scheme 3 x 2 x 2 x 2: RCP (control, enhancement of one and two times the enzyme protease), PRO (with and without protease), STO (room temperature and refrigerated) and TM (14 and 28 days), with seven replications of one egg per experimental unit. The factorial scheme 3 x 2 x 2 was used at 58 weeks of age, because...
