Sensory and shelf-life characteristics were measured for beef top rounds enhanced to 110% with 0.5% sodium chloride and 0.4% sodium tripolyphosphate (CNT);CNT with a 1% solution of 80% sodium citrate plus 20% sodium diacetate (SC + D);or CNT with 2% buffered vinegar (VIN) in the final product. SC + D and VIN had less (P 0.05). However, SC + D had lower (P 0.05) for all enhancement solutions within each day. After 7 days of retail display, SC + D retarded (P < 0.05) lipid oxidation to a greater extent than VIN or CNT samples. Sodium citrate plus sodium diacetate or buffered vinegar may be included in enhancement solutions without having a large influence on subjective color, and may aid in improving sensory tenderness.展开更多

The very basic PSO model and some variants of PSO do not consider the enhancement of the explorative capability of each particle. Thus these methods have a slow convergence speed and may trap into a local optimal solution. To enhance the explorative capability of particles, a scheme called explorative capability enhancement in PSO（ECE-PSO） is proposed by introducing some virtual particles in random directions with random amplitude. The linearly decreasing method related to the maximum iteration and the nonlinearly decreasing method related to the fitness value of the globally best particle are employed to produce virtual particles. The above two methods are thoroughly compared with four representative advanced PSO variants on eight unimodal and multimodal benchmark problems. Experimental results indicate that the convergence speed and solution quality of ECE-PSO outperform the state-of-the-art PSO variants.展开更多
