  • Objectives of this study were to investigate the acceptability of liver sausages, one of the most favorite product of meats, and to examine the applicability of pork liver in manufacturing sausages. Sausages containing different proportions of pork liver were manufactured with various processes and were tested and analysed by means of sensory evaluation. Based on th basic recipe for manufacturing sausages, fifteen recipies were proposed with different combinations of ingredients, followed by evaluations on their physicochemical and nutritional properties. Sausages manufactured with different methods (sliceable, spreadable, smoked spreadable) and different proportions of liver were also evaluated. The Findings from these experiments are summarized as follows: 1. As the percentage of the liver was increased, outer color of experimental sausages were significantly decreased. 2. The hardness, gumminess, chewiness were significantly decreased as the amount of liver increased. 3. Sausages containing 30% pork liver had best acceptability after swallowing. 4. The flavor and taste of liver in experimental sausages were significantly increased by adding liver. In summary, sausages containing 30% pork liver had best acceptability for consumption in terms of the indices measured in this study.

  • Liver sausage is flavorful and highly nutritious. However, liver has a relatively short shelf life due to acceleration of oxidation in the presence of endogenous enzymes and metals. Powders derived from natural sources, including plants or fruits, are applied to meat products for inhibiting oxidation without adverse effects on their quality. Hence, this study investigated the effects of natural powders derived from green tea leaf (GTL), lotus leaf (LL), and kimchi (KC) on the quality and change in lipid oxidation and freshness of chicken liver sausages during two weeks of storage. Chicken liver sausages were manufactured with chicken breast (70%) and liver (20%), pork back fat (5%), iced water (5%), various additives, and GTL, LL, and KC [0 (control) or 1%]. They were processed in three batches. For determination of the quality characteristics of chicken liver sausages with various plant powders, pH, color, and texture properties were assessed. In addition, lipid oxidation and freshness using thiobarbituric acid reactive substances (TBARS) and total volatile basic nitrogen (TVBN) were analyzed at day 0 and week 2 of refrigerated storage. Higher values were obtained for pH and cooking yield in sausage samples with LL and KC powders than in samples with the other treatments. For a* values, the sausage samples with KC showed similar (p > 0.05) values, whilst others had significantly lower values than the control. The addition of the three powders to sausage samples induced an increase (p < 0.05) in hardness, gumminess, and chewiness. The addition of plant powders did not influence TBARS and TVBN of sausage samples at the initial stage. However, after two weeks of storage, significantly lower TBARS and TVBN values were observed, and the sausage with KC (p < 0.05) showed the lowest values of both TBARS and TVBN. The results showed the potential ability of the three powders to improve the quality and inhibit lipid oxidation in liver sausages. Particularly, the addition of KC did not adversely affect the $a^*$ values of sausage samples. The effects on sensory properties and inhibition mechanisms of GTL, LL, and KC in meat products should be further studied.

  • Objectives of this study were to investigate the lipid oxidation of liver sausages, one of the most favorite meet products and to examine the applicability of pork liver to sausages. Sausages containing different proportions of pork liver were manufactured with various processes and were tested and analysed by means of lipid oxidation. Based on the basic recipe for manufacturing sausages, fifteen recipies were proposed with different combinations of ingredients, followed by evaluations on their contents of crude fat, AV, POV, and MA. Sausages manufactured with different methods(sliceable, spreadable, smoked spreadable) and different proportions of liver were also evaluated. In addition, the storage experiments were carried out. The findings from these experiments are summarized as follows : The content of crude fat was 17.12%. As the percentage of the liver increased, fat content of sausages siginificantly decreased. In the storage experiment, it was found that the acid value, peroxide value, and malonaldehyde content significantly increased in all samples regardless of the amount of liver or the storage time. The AV of experimental sausages was significantly increased by adding liver. There were significant differences in proportions of components but little differences were observed in contents among the samples.

  • The aim of this study was to evaluate the effect of kimchi powder levels (0, 1, 2, and 3%) and pork skin (5%) on the quality characteristics of liver sausages. The additions of the kimchi powder and pork skin improved the color, cooking yield, and sensory properties of the sausages. The addition of the pork skin and increasing concentrations of the kimchi powder significantly increased cooking yields. The moisture and protein contents of the sausages made with kimchi powder and pork skin were higher than those of the control (p<0.05). Due to the low pH of the kimchi powder, the pH values of the batter and sausages with added kimchi powder were lower than those of the treatment without kimchi powder (p<0.05). The control had the lowest hardness, gumminess, and chewiness values (p<0.05). For the sensory attributes of the samples, color, flavor, juiciness, and overall acceptability were higher in the treatments made with kimchi powder than in the treatments without kimchi powder, in which the treatment with 2% kimchi powder had the highest overall acceptability (p<0.05). In conclusion, the additions of kimchi powder and pork skin improved the quality characteristics of liver sausages.

  • The purposes of this study were to investigate the applicability of pork liver in manufacturing sausages and to examine the nutritional components of liver sausages prepared. Sausages containing different proportions of pork liver were manufactured with various processes and were analysed for their nutritional value. Based on the basic recipe for manufacturing sausages, fifteen recipes were proposed with different combinations of ingredients. Sausages manufactured with different methods (sliceable, spreadable, smoked spreadable) and different proportions of liver also were evaluated. The results were obtained as follows : 1. The average contents of moisture, protein, fat, carbohydrate, fiber, ash, and energy were 62.31 %, 15.71 %, 17.12%, 3.88%, 0.24%, 1.48%, and 234.04 kcal/100 g respectively. As the percentage of liver increased, the fat content and total energy were decreased significantly. 2. As the percentage of liver in sausage increased, the content of amino acids including valine, leucine, isoleucine, threonine, lysine, phenylalanine, arginine, aspartic acid, glycine, proline, tyrosine, and cysteine was increased. However, the contents of histidine, methionine, glutamic acid, and alanine were decreased. 3. The vitamin A content of liver sausage was increased by 11 times compared with the control, however, the content of vitamin B was slightly decreased. 4. As the percentage of the liver was increased in sausage, the content of minerals such as calcium, magnesium, phosphorus, sodium, potassium, and iron were increased.

  • This study was performed to investigate the serum lipid and cholesterol lowering effects of kimchi powder or Lactobacillus plantarum when added to fermented sausage in rats. Male SD (Sprague-Dawley) rats were divided in three groups and administered with the following diets for 6 wk: non-fermented sausage added diets (CON), kimchi fermented sausage added diets (KIM), and Lactobacillus plantarum fermented sausage added diets (PLA). The CON has significantly (p<0.05) higher food intake, body weight gains, and final body weight than the other two groups. The body weight of KIM was significantly (p<0.05) lower than that of the other groups. The weights of organs (heart, lung, liver, kidney, spleen, perirenal adipose tissue, and epididymal adipose tissue) were not affected by any treatments. The mean value of serum triglycerides (TG) concentration in KIM and PLA groups was not significantly different compared with CON. Total cholesterol, low density lipoprotein and high density lipoprotein levels in serum of KIM were significantly (p<0.05) lower than those of CON. The serum free cholesterol level and atherogenic index (AI) in KIM and PLA were significantly (p<0.05) lower than those of CON. In conclusion, dietary supplementations with kimchi powder fermented sausages or L. plantarum fermented sausages were effective for lowering serum lipid, cholesterol levels and atherogenic index in rats.

  • The current study was designed to assess the effects of emulsified sausage supplemented with ginseng saponin on lipid metabolism by applying a rat model. Four groups of 8 rats (5 wk old) were each allocated one of 4 treatments: basal feed (C), and basal feed with 20% sausage powder containing 0% (S0), 2% (S2) and 4% (S4) ginseng saponin. The experiment was conducted for 4 wk. The results did not differ among the treatments with different amounts of sausage (ST), but daily feed intake (p<0.01) and feed conversion (p<0.001) were significantly increased in STs compared to C. Both total serum cholesterol and triglyceride concentrations were significantly (p<0.001) reduced, by 45 and 46%, and 48 and 46%, in S2 and S4, respectively, compared to S0. In the liver, the total cholesterol level was dramatically (p<0.05) decreased according to increasing sausage powder levels. In particular, S4 showed approximately 14% reduction compared to S0 (p<0.05). Liver triglyceride content also showed a similar tendency, where S2 and S4 resulted in 7% and 31% reduction. With regard to fatty acid composition in the liver tissues, palmitic acid (16:0), oleic acid (18:1), eicosanoic acid (20:1), and eicosatrienoic acid (20:3) did not differ among the STs, whereas both linoleic acid (18:2) (p<0.01) and linolenic acid (18:3) (p<0.001) showed significant increases in S2 compared to S0. The current data demonstrated that emulsified sausages supplemented with ginseng saponin effectively reduce total cholesterol and triglyceride concentrations in the serum and liver, and increase unsaturated and essential fatty acid in the liver. These data collectively imply that the sausage improved the overall lipid profile in a rat model, and can be further generalized to the result that emulsified sausage can improve lipid metabolism depending on the products' formula.

  • This experiment aims to observe the nutritive value of blood sausages by manufacturing three kinds of them in order to utilize various by-products of swine when it is processed. In attempt to do so, five different diets were made: one control diet and four diets in which three kinds of blood sausages(blood sausage-1 was made with sausage meat 10%, fat 40%, blood 20%, skin 20% and liver 2%. blood sausage-2 was made with ham meat 30%, fat 20%, blood 20%, liver 2% and skin 20%. blood sausage-3 was made with smoked ham patch 30%, fat 20%, blood 20%, liver 2% and skin 20%) and mixed sausage(sausage meat 20%, fat 10% and fish meat 35%) were mixed with control diet at the rates of 10% respectively. These diets were fed to growing male and female albino rats for 6 weeks. The results obtained through this study are summarized as follows. In body weight gain of male rats, blood sausage-1 and 2 groups were significantly higher than mixed sausage group during the experimental period, and in that of female rats, control group and blood sausage-1 group were similar, but the other groups were lower than control group. Food intake was different in each group every week, but the amount of that was similar to each one throughout all experimental period. Food efficiency ratio and protein efficiency ratio in male were similar in each group, but slightly different in female during the feeding period. Liver weights of male in mixed sausage group and blood sausage-3 group were lower than those in control group and blood sausage-2 group, but liver weight of female in blood sausage-2 group was lower than that in control group. And all groups were similar in liver weight per 100 g of body weight. Mixed sausage group and blood sausage-1 group were lower than control group in kidney weight of male, and blood sausage-1 group was lower than control group in kidney weight of female. Kidney weight per 100 g of body weight of male showed that blood sausage-1 group was lower than the other groups. Spleen weight was similar in all groups. Hematocrit and hemoglobin contents in blood, total protein, albumin, albumin/globulin ratio, total lipid and total cholesterol contents in serum were showed almost similar in all groups.
