Water binding ability (WBA), held water (HW) and gel-forming properties of silver carp (Hypophthalmichthys molitrix Val) and carp (Cyprinus carpio Lin) meat were examined in this paper. Two variants of fish meat gels: A with 50% of meat and B with 60% of meat were examined at temperatures: 70 75, 80, 85 and 90 oC. The variant A of silver carp meat gels has shown the maximum of WBA and HW at 80 oC, and the variant B at 75 oC. In both variants of carp meat gels slow increase of WBA and HW with rise of temperature to 80oC was established. Silver carp meat gels have had better WBA than control gels (beef and poultry meat), and carp meat gels have better HW, but somewhat worse WBA than control gels. In gels of variant A of silver carp meat the highest module of elasticity (6.862 N/cm2) was found at thermal treatment at 85 oC, but statistically significant differences in relation to other temperatures were not established. In variant B, with the rise of temperature, the module of elasticity increases; statistically significant differences were established among gels treated at 70 oC and others. Differences between variants A and B were statistically significant at all examined temperatures. Meat gels of silver carp have significantly lower module of elasticity compared to control gels. Under conditions of our experiment the module of elasticity of carp meat was below measuring limit
The present study was undertaken to investigate the effects of the presence of different concentrations of GRINSTEDTM Carrageenan CC 250 (0.25%, 0.4% and 0.55% related to the mass of raw material) on selected technological and sensory properties of smoked pork loin. Changes in mass during production process and water content were observed. Sensory evaluation included estimation of cut appearance, consistency, odor, taste, color, tenderness firmness and plasticity. It was found that water retention and muscle structure binding were strongly influenced by carrageenan addition. Depending on applied concentration of preparation, achieved yields varied from 1.08% to 2.06%
Authors examined the effects of SUPRO 595 and GRINSTED™ Carrageenan CC 250 addition on selected sensory properties of smoked pork loin. Sensory evaluation of products included an estimate of cut appearance, texture odor, taste and color. Using photoelectric tristimulus colorimeter (the MOM Color - D) determination of color characteristics in pork loin samples was carried out. The values for psychometric lightness (L*), psychometric hue redness (a*) and psychometric chrome - yellowness (b*) were expressed based on the CIELAB system. Tenderness and firmness of samples were instrumentally measured on an "INSTRON" - 4301, under the given working conditions. The variants of smoked pork loins with soy isolate were better evaluated compared to the variants with carrageenan. The results of instrumental determination of color characteristics of the products showed that between the variants with soy isolate and the variants with carrageen there existed insignificant deviation in the values of psychometric lightness (L*), in the presence of redness (a*) and in the presence of yellowness (a*). Instrumentally measured tenderness and firmness showed that the samples with carrageen were characterized by somewhat greater tenderness and firmness compared to the samples with soy isolate
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
