Effects of deheading and rinsing pretreatment on the quality of white leg shrimp (Litopenaeus vannamei) surimi based on endogenous proteases.

In this study, the effects of different pretreatments on the quality of white leg shrimp surimi were investigated based on shrimp endogenous proteases. The results showed that removing the head and rinsing significantly (P < 0.05) improved the gel strength, texture, whiteness, water distribution, and microstructure of the shrimp surimi gels.

Simulation of the Effect of Artificial Water Transfer on Carbon Stock of in the Baiyangdian Wetland, China.

How to explain the effect of seasonal water transfer on the carbon stocks of Baiyangdian wetland is studied. The ecological model of the relationship between the carbon stocks and water depth fluctuation of the reed was established by using STELLA software. For the first time the Michaelis-Menten equation (1) introduced the relation function between the water depth and reed environmental carrying capacity, (2) introduced the concept of suitable growth water depth, and (3) simulated the variation rules of water and reed carbon stocks of artificial adjustment.
