The effect of ice-storage duration (0, 3, 6, 9, 12, and 15 days) of silver carp (Hypophthalmichthys molitrix) on qualitative properties of its surimi powder was assessed by analyzing proximate composition, color changes, density, oil adsorption capacity, protein solubility, emulsifying capacity, emulsion stability, gel forming ability, and thiobarbituric acid. Increase in ice-storage duration increased the density and thiobarbituric acid of surimi powder(p<0.05); proximate composition, color indices, protein solubility, oil adsorption and gel forming decreased significantly (p<0.05); emulsifying capacity and emulsion stability decreased with storage duration, although no regular trends were detected (p<0.05).  The present study indicated that long-term ice-storage of silver carp led to reduction of qualitative properties of the surimi powder.

To improve the texture and acceptance capabilities of silver carp burger and increase per capita consumption this product, the pectin was used as texture enhancers. Pectin is a polysaccharide that can be used in food to improve gel texture properties. In this research uses three different treatments, silver carp fried fish burger as control, fried fish burger with 0/3 % pectin as treatment 1, fried fish burger with 0/6 % pectin as treatment 2. Sensory evaluation and texture analysis tests was performed in zero phases and then monthly for six months and the results were compared with texture analysis. According to the results of the texture analysis of fish burger treatments, significant differences in the juiciness,overall acceptance was observed.The sensory evaluation index are also significant differences between fish burger formulated contains 0/3% pectin than the other two treatments was observed after six months storage at-18°C, therefor according to sensory evaluation and texture analysis, formulating fish burger contains 0/3% pectin most stable and acceptable formulation in terms of scoring during storage.

Due to the increasing consumption of ready-made foods such as burgers and their popularity among the general population, the aim of the present study is to produce mixed burgers with different percentages of surimi and chicken minced and also, increasing the maintenance time of burgers by adding cumin and thyme essential oils (500 ppm) to burgers. First, surimi gel was produced and burgers formulated with the surimi and chicken minced based on applying the Response Surface Methodology. By analyzing the results of sensory evaluation using RSM that the best formula for burgers was chicken 37% + surimi 63%, then the pH, total volatile basic nitrogen, thiobarbituric acid and peroxide values and some microbiological characteristics were studied on selected burger for the duration of storage 27 days at 2 ⁰C. The results showed that essential oils had a significant effect on the chemical and microbiological parameters in comparison with the control group (without essential oil) throughout the entire period. The use of thyme/cumin essential oils showed the good effect to extend the shelf life of fresh new formulated burgers. So that, in the presence of essential oils, the burgers can be stored for up to 9 days in terms of microbiological and chemical factors, although some of the chemical factors (TBA in all groups and TVN in the presence of essential oils) did not exclude the end of the maintenance period. The results show that optimum burger production with Surimi and chicken minced meat in the presence of essential oils is an appropriate option for the industries that sell their products as fresh meat products.
