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.
