Makgeolli lees is a by-product of the makgeolli brew processing. Makgeolli lees contains high levels of fibers, which can be separated and used to develop foods rich in dietary fibers. The purpose of this study was to determine the effect of makgeolli fibers (0-4%) on proximate composition, caloric content, pH, color, cooking yield, textural profile, and sensory characteristics of chicken-emulsion sausages. The moisture content of 1, 2, and 3% makgeolli lees fiber-amended product was higher than the control, while that of the 4% product was not. Total calorie estimates of makgeolli lees fiber-amended sausages were lower than the control, except for in the case of the 4% treatment. Moreover, chicken sausages supplemented with makgeolli lees fiber had higher cooking yields and improved textural properties. Chicken emulsion sausages prepared with makgeolli lees fiber had improved overall acceptability, and the best results of sensory characteristics were obtained for the emulsion sausages containing 2% makgeolli lees fiber.

This study was carried out to estimate the bind values of raw meats which are used as an input constaint in the least-cost formulation of an emulsion-type sausage. The least-cost formulation will be useful for Korean meat processore to produce more effectively as meat-grade system is put in force. The analysis results in compositions, functionalities, and pigment contents of raw meats were various according to the difference of species and their parts. The cohesiveness was correlated positively with moisture or protein content and negatively with fat content. Consequently two multiple regression equations for bind value could be derived from the compositions of raw meats. The equations then may be useful for predicting the bind value of a raw meat which presently has not been analysed.

Objective: The purpose of this study was to investigate whether addition of konjac gel with three different vegetable powders can increase quality of low-fat frankfurter-type sausage. Methods: Low-fat frankfurter-type sausages were manufactured with formulations containing konjac gel and three vegetable powders (aloe vera, cactus pear, or wheat sprout) as pork fat replacers. The formulations of frankfurters were as follows: NF (normal-fat; 20% pork fat), LF (low-fat; 10% pork fat), KG (low-fat; 10% pork fat+10% konjac gel), and konjac gel with three vegetable powders (KV), such as KV-AV (10% pork fat+10% konjac gel with aloe vera), KV-CP (10% pork fat+10% konjac gel with cactus pear), and KV-WS (10% pork fat+10% konjac gel with wheat sprout). Proximate analysis, pH value, color evaluation, cooking loss, water-holding capacity, emulsion stability, apparent viscosity, texture profile analysis, and sensory evaluation were determined. Results: The konjac gel containing groups showed lower fat content (p<0.05) and higher moisture content than NF group (p<0.05). The pH value of frankfurters was decreased in three KV groups (p<0.05). The three KV groups had increased dark color (p<0.05) compared with KG, and KV-CP had the highest redness (p<0.05). The water-holding capacity and emulsion stability were higher in the three KV groups than KG and LF (p<0.05). Cooking loss was generally decreased in the three KV groups, compared with KG (p<0.05). The apparent viscosity of KV groups was similar with NF group and overall texture properties were improved in KV-CP. In the sensory evaluation, the highest overall acceptability was found in KV-CP groups (p<0.05). Conclusion: The four fat replacers improved physicochemical properties of low-fat frankfurters. Particularly, konjac gel with cactus pear powder seems more acceptable as a pork fat replacer.

This study was conducted to evaluate the effects of salt soluble protein extracts from anchovy (ASSPE) on sausage during storage at $10^{\circ}C$. Sausages were produced containing 5 and 10% ASSPE. Sausages containing ASSPE showed no significant differences in emulsion stability, color, pH, moisture, viable cell count, and VBN compared to the control. The hardness significantly increased with the addition of ASSPE, and sausages containing 5% ASSPE were the highest in gumminess. In the sensory evaluation, sausages containing 5% ASSPE had the highest score in appearance and springiness. In conclusion, the addition of ASSPE in sausage had no effects on storage characteristics, but had a good effect on improvement of quality and sensory characteristics. Especially, 5% ASSPE sausage had good texture and high sensory characteristics due to increased binding capacity. These results suggest that 5% ASSPE may improve the quality and sensory characteristics of sausage.

Combined effect of modified atmosphere packaging and gamma irradiation on color characteristics of emulsion-type cooked pork sausage were investigated. Nitrosomyoglobin (NO-Mb) contents and CIE color values of sausage with aerobic, $CO_2, \;N_2$, and $CO_2/N_2$ packagings were observed during storage for 4 weeks. Irradiation reduced NO-Mb content in sausage, inducing denitrosylation of nitrite-cured meats. $CO_2$ and $CO_2/N_2$ packagings were effective for maintaining NO-Mb content. In CIE color values, $a^*$ was significantly reduced by irradiation at 5 kGy and above. The $a^*$ values of sausages with $CO_2$ and $CO_2/N_2$ packagings were higher than those of aerobic or $N_2$ packaging. Results indicated that modified atmosphere packaging, such as $CO_2$ or $CO_2/N_2$ packaging, was effective for minimizing the loss of red color in sausage caused by irradiation.

Guar gum and $\kappa$-carrageenan were investigated as a substitutes for phosphate in pork meat processing. Emulsion-type pork sausages were prepared in which 0.5% phosphate was used for the control, and either $\kappa$-carrageenan or guar gum were added at levels of 0.1 or 0.5% for comparison. The hydrocolloid compounds significantly enhanced water holding capacity and cooking loss. However, hardness, cohesiveness, and chewiness were not well-maintained when compared to the control; this was attributable to the altered water distribution as well as enhanced water holding capacity of the sausages by the addition of $\kappa$-carrageenan and guar gum. Furthermore, the phosphate-free sausages had similar storage stability as the phosphate-added sausage. Overall, the results suggest that $\kappa$-carrageenan or guar gum can be used in place of phosphate in conventional processing to successfully prepare phosphate-tree pork sausages.

Cold plasma has been developed to reduce microbial contamination and to improve safety of food and medical products. In addition, the technology can be used in the manufacture of sausages without addition of nitrite. To be applied in food industry commercially, the new technology should be safe and efficient. However, toxicological test of plasma-treated food is limited. Therefore, the purpose of this study was to determine the mutagenicity and immune toxicity of the meat products cured with plasma-treated water (PTW) as a nitrite source. Emulsion sausages were prepared with no nitrite (control), sodium nitrite (SCS), and PTW (SCP). For a mutagenicity test, the Ames test was performed with the sausage samples. For immune toxicity test, 8-wk-old female Balb/c mice were given free access to the sausages in order to evaluate the tumor necrosis factor (TNF)-α level. As a result, no mutagenicity was detected in the sausages by the Ames test. The serum TNF-α values were less than 10 pg/mL in mice after feeding control and treated samples for 32 d, indicating that no inflammatory response was occurred by feeding the sausages made by PTW. Therefore, the present study opens the possibility of using plasma-treated water as a nitrite source without any toxicity.

The effects of the addition of Kimchi powder at levels of 1%, 2%, and 3% (w/w) to sausage formulation on the quality characteristics of low-fat sausage were determined. The CIE L-values of low-fat sausages were lower than the control (p<0.05), and were inversely proportional to the level of Kimchi powder (p<0.05). The CIE a- and CIE b-values of sausages increased with increasing levels of Kimchi powder (p<0.05), and the pH of sausages decreased in proportion to Kimchi powder acidity. Kimchi powder was effective at retaining added water in low-fat sausages since cooking yield, emulsion stability, and viscosity with the addition of 3% Kimchi powder was similar to that of the control. The protein and ash contents of sausages were not affected by Kimchi powder addition (p>0.05), while sausages containing 3% Kimchi powder had the highest water content (p<0.05). With increasing Kimchi powder concentration, hardness, gumminess, chewiness, and sensory scores increased in low-fat sausages (p<0.05).

Breakfast sausages containing 1, 2, 3, and 4% sea tangle powder (Lamina japonica) were prepared. No differences were found in moisture, protein, and fat contents among the control and treatments. However, the ash content increased with increasing amounts of sea tangle powder (p<0.05). The pH levels in the treated samples were lower than the control in both the meat batters and the breakfast sausages (p<0.05). The $L^*$ and $a^*$ values of the meat batters and breakfast sausages were decreased by the addition of the sea tangle powder, and the control had the highest $b^*$ value (p<0.05). The added sea tangle powder improved cooking loss and improved emulsion stability. The T4 sample (containing 4% sea tangle powder) was shown to have the lowest cooking loss and water loss (p<0.05). The hardness, gumminess, and chewiness of the treatments increased compared to the control due to the presence of dietary fibers in the sea tangle. In the sensory evaluations, the 1% sea tangle powder treatment received a lower color score, but received significantly higher scores for flavor, tenderness, and juiciness (p<0.05). Collectively, the breakfast sausage containing 1% sea tangle powder was determined to have the highest overall acceptability. Altogether, the best results, in terms of physicochemical and sensory properties, were obtained for the breakfast sausage containing 1% sea tangle powder.

Objective: The objective of this study was to evaluate the effects of ageing time of lamb loins prior to freezing on technological characteristics and oxidation stability of coarse ground lamb loin sausage using in a model system. Methods: Lamb loins (M. longissimus lumborum, n = 25) were aged at $-1.5^{\circ}C$ for 0, 1, 2, 3, and 8 wk and then frozen for the remaining days (a total of 30 wk). The aged/frozen/thawed lamb loins were ground, and model sausages were formulated with 75% aged/frozen/thawed lamb loin, 25% water, 1.5% sodium chloride (NaCl) and 0.3% sodium tripolyphosphate. The pH and thaw/purge loss of aged/frozen/thawed lamb loins were evaluated, and protein functionality (protein solubility and emulsifying capacity), water-holding capacity and textural properties of model sausages were determined. Cooked model sausages were vacuum-packaged in a plastic bag and displayed under continuous fluorescent natural white light ($3^{\circ}C{\pm}1^{\circ}C$). Colour and lipid oxidation of the cooked model sausages were evaluated on 0 and 21 d of display storage. Results: Ageing prior to freezing had no impact on pH and purge/thaw loss of lamb loins and the colour of cooked sausages (p>0.05) made from the loins. Lamb loins aged for at least 3 wk prior to freezing numerically improved total and myofibrillar protein solubilities (p>0.05) and emulsion activity index (p = 0.009) of meat batter, but decreased cooking loss (p = 0.003) and lipid oxidation (p<0.05) of model sausages. Conclusion: This study suggests that post-mortem ageing of raw meat prior to freezing could improve water-holding capacity and lipid oxidative stability of sausage made from the meat.
