Substantiation Of Hot Smoking Parameters Based On Sensory Researches In Hot Fish Marinades Technology In The Jelly Pouring

Modern technologies of food products provide creation of healthy, tasty and safe products, characterized by high organoleptic properties, balance by main food factors and structural-mechanical parameters of a product.The main technological process in the technology of fish marinades and a jelly pouring is the hot smoking. Technological parameters of the hot smoking have been scientifically grounded on the base of the statistical processing of data of sensory studies. Organoleptic assessment of semi-products after the thermal processing was carried out by 5-point system corresponding to the elaborated scale. The quantitative assessment of organoleptic parameters of the quality of experimental samples was determined by the totality of all assessment points, taking into account chosen weight coefficients depending on the importance degree of a given parameter at forming consumer qualities of a product. The generalizing quality parameter was calculated as a sum of assessments of organoleptic parameters – taste, consistence and appearance. Individual assessments of separated quality parameters of products (in points) were put in degustation lists and statistically processed by the averaging method.The smoking process realization, according to scientifically grounded parameters allows to produce the new type of tasty, healthy and presentable culinary products of a perspective object of Ukrainian aquaculture – silver carp of a prolonged storage term

A Technology Developed to Produce Hot Fish Marinades for a Jellylike Filling of Prolonged Storage

Aquaculture is a promising way of developing fisheries worldwide and in Ukraine. Aquaculture products should form the basis of a complete nutrition of the population of Ukraine in accordance with the world tendency. About 44 % of freshwater catches in 2015 were those of the silver carp. The range of food products from the silver carp is limited, which is due to the low activity of its enzyme system, which does not facilitate maturation in the production of salty fish products. Therefore, new kinds of silver carp products are suggested in jellylike marinade fillings of prolonged shelf life.The results of the statistical processing of complex organoleptic tests have determined the rational parameters of the hot smoked salty semi-finished product. It is proposed to conduct drying at a temperature of 60...70 °С for 25 minutes; evaporation is advised to be performed for 25 minutes at a temperature of 100...110 °С. The stage of the actual hot smoking should be carried out at a temperature of 90...100 °C for 45 minutes. The samples studied, which were smoked according to the above parameters, received the highest score. In order to provide stable structural and mechanical properties of the jelly during refrigeration, the formulation of the filling was substantiated. A combination of LEP and alginic acid in a ratio of 1:1 with a mass fraction of 1.5 % forms a jelly as strong as 112 g and with no synergetic changes. The developed technology helps obtain safe fish marinades in a jellylike filling with a shelf life of up to 90 day
