An investigation was made into the effects of various egg white products and sweeteners on the stability and organoleptic properties of egg white foams. 12 foam products were prepared from egg white a...
The work was targeted on the study of egg white foam forming, including the influence of pH, aluminium ions, xanthan, maltodextrin, and phosphates on the whipping and stability of egg white foams. The...
采用酶法制备蛋清肽,色谱纯化ACE抑制活性组分并鉴定其一级结构。通过考察底物质量分数、加酶量、酶解温度和pH值对水解度的影响,结合多元线性回归设计和二次回归正交组合设计建立蛋清ACE抑制肽酶解工艺模型,并经液相色谱串联质谱鉴定其一级结构。结果表明:最佳酶解工艺为底物质量分数8%、pH值10.73、加酶量12.14%及酶解温度56.80℃,酶解物纯化后半抑制质量浓度为0.18mg/mL。液相色谱串...
Taking into account the enzyme inactivation and substrate inhibition, the bioreaction mechanism and kinetics characteristic of egg white protein (EWP) enzymatic hydrolysis by pepsin were investigated....
采用Box-Behnken模型对卵清蛋白糖基化反应过程进行优化,测定并分析了糖基化卵清蛋白在各种条件下的乳化性质。结果表明其最佳反应条件为:糖添加量9%,反应时间48h,反应温度60℃,在此条件下乳化活性为1.328,乳化稳定性为9.63min,相对卵清蛋白分别提高了3.7倍和8.75倍。糖基化程度与乳化活性及乳化稳定性的关系符合Lerentz函数。糖基化卵清蛋白的乳化性质相对不受低pH值和高离子...
研究了高压脉冲电场(PEF)与温和热协同处理对蛋清中嗜冷菌——单增李斯特菌的杀灭效果。结果表明,当处理温度为15℃时,20、25、30和35kV/cm电场强度作用400μs,每1mL蛋清所含李斯特菌数分别降低了0.8、1.4、2.3和3.8个数量级。当处理温度升至55℃时,每1mL蛋清总菌数分别降低了1.3、2.5、4.9和6.4个数量级。当处理温度为15℃,35kV/cm作用100、200、30...
The mechanism of antitumor activities in hen egg white ovomucin (OVM) was analyzed by examining the interaction between the 120 kDa fragment (a highly glycosylated fragment in β-subunit from the prona...
Ttypsin and α-amylase were immobilized on glycosylated egg white-beads by simple incubation of the beads in a solution of an enzyme for 24 h at 30°C. This process included no artificial chemical modif...
The intraperioneal administration of β-subunit prepared from egg white ovomucin was found to suppress the growth of subcutaneously xenografted sarcoma-180 cells in mice and cure the tumor. In the pres...
When sarcoma-180 (SR-180) cells were incubated with α- or β-subunit prepared from insoluble ovomucin in the gel fraction of egg white, the cell proliferation rate was apparently reduced by the additio...
Characterization of the mechanisms of improvement of Chinese noodles by dry-heated egg white, were estimated by rheological and spectroscopic data of the effects of dry-heated egg white on wheat starc...
Heat stable ovomucoid (OM) is a major allergenic protein of chicken eggs, which are widely used in wheat flour processed food. PBS soluble OM remained in the cookies prepared by the usual method. A pr...
Egg white sols diluted with various liquids are easily converted to soft, smooth gels by heating. In this study, the effects of various salts on the properties of diluted egg white gels were investiga...
We examined the effects of several tea extracts containing certain polyphenols on the physical properties of egg white gel. The results of compression tests showed that it was possible to increase the...
Two magnetic macroporous cellulose cation exchangers (Iontosorb MG CM 100 and Iontosorb MG SHP 100) were used for one-step isolation of lysozyme from native, undiluted hen egg white. Highly purified l...
