Effect Of Cacl2 On Water Holding Capacity And Microstructure Of Tilapia Myosin Gel Under The Low Salt Condition, Feng Rui, Hong Peng-Zhi, Yang Ping, Zhou Chun-Xia
Food and Machinery
Myosin was extracted from tilapia (Oreochromis niloti-cus) and the heat-induced gel was prepared, and the effect of CaCl2 addition on the water holding capacity, microstructure and chemical interactions of myosin gel was investigated under different salt conditions (1,50,150,600 mmol/L NaCl). The effects and mechanisms of Ca2+on thermal gel properties of myosin were determined under the low salt conditions. Experimental results showed that under the conditions of low salt concentration (1~150 mmol/L NaCl), there were weak opaque gels due to a rapid aggregation of myosin filaments during heating. These myosin gels exhibited a cross-linked network with coarse cross-linked …

In order to explore the causes of fish tenderness changes during microwave cooking of boiled fish, the physical property analysis method can be used to characterize the maximum shear force of fish meat, and it can also be analyzed from the perspectives of water state, protein denaturation and microstructure by method of measurement like Low field nuclear magnetic resonance(LF -NMR). The results showed that at the first stage of microwave heating (150 s), the connective tissue in fish meat was rapidly broken, and the sarcoplasmic protein was almost denatured completely. Part of the bound water was converted into immobilized water, …

In this paper, the effects of exopolysaccharide (EPS) produced by lactic acid bacteria (LAB) on the foaming, surface hydrophobicity and liquid protein content of complex proteins during whipping were studied. LAB fermentation technology was applied in the production of eggless cakes and its effect on batter rheological, baking characteristic and crumb microstructure of eggless cake were evaluated. The results showed that the EPS produced by LAB significantly improved the foaming properties, increased surface hydrophobicity of complex protein and maintained the interface protein content by reducing competitive adsorption of emulsifiers during whipping. The number of bubbles increased and their distribution was …
