Abstract

In the presented research the effect of salt intake on chemical compositions, sensory properties, and oxidative stability of Clupeonella cultriventris caspia fish, through hot smoke process, storage in refrigerator conditions, was studied.To achieve this, after initial preparation activities, the samples were exposed in Brinning process within two salt concentrations of NaCl/KCl under 15% brine solution with 5 ºC refrigerant process for 3 hrs. The smoking process included turning the samples into drying and hot smokes by slow and high rates of smoke set. All of the samples were tested by sensory analysis and salt intake concentration to select the nominated treatments in future. The results of the chemical tests showed that, there were not significant differences between treatment1 (control, and salt NaCl/KCl with ratio 0/100%) and treatment 2 (salt, NaCl/KCl with ratio of 25/75%) regarding the amount of fat, moisture content, ash and a TBA indexes. Protein levels and salt intake were significantly increased while the TVB-N and PV indexes decreased in treatment 2. Microbiological tests were also confirmed that the rate of mold was significantly greater in treatment 2 than treatment 1 in early days, however being reduced later in both. Totally, the number of 28 fatty compositions was identified. Palmitic acid (C16: 0) was significantly increased in treatment 2, however Oleic acid (C18: 1 cis) was reduced in treatment1. The sensory analysis showed that there were not significant differences between two studied treatments. According to the results, sodium chloride could be replaced with potassium chloride without negative effects on chemical, microbiological and sensory properties, replace up to 25% in hot smoked tofu.
