This study evaluated the effects of dietary fiber extracted from rice bran on the chemical composition, cooking characteristics and sensory properties of emulsion type sausage. Sausages were produced containing 0%, 1%, 2%, 3%, and 4% dietary fiber extracted from rice bran. The negative control had the highest fat, cooking loss, CIE L- and CIE a-values. The sausages containing rice bran had higher moisture, ash, pH, and CIE b-values than the control. Sausages with 3% rice bran had the lowest cooking loss. Sausages with 4% rice bran had the highest hardness and cohesiveness. There was a significant difference among the emulsion sausage samples with respect to sensory properties, with sausages containing 1% and 2% rice bran having a higher overall acceptability than the other sausages.

A surimi like material was made from fresh pig hearts and used to manufacture emulsion-type sausages for the improvement of quality characteristics. The heart muscles were diced and frozen at -60$^{\circ}C$ until processed. Then, the frozen diced heart muscles were thawed, chopped, filtered, and washed to extract myofibrillar proteins. The residue was centrifuged to take a surimi-like material. Emulsion-type sausages were made different levels of surimi-like material(5∼15%) and compared to the control. Cooking loss(CL, %) and water-holding capacity (WHC, %) were measured on raw meat batter, whereas shear force, hardness, color and panel test were measured after cooking. The addition of the surimi-like material up to 15% level in the sausage formulation reduced CL and increased WHC, as compared to the control. Shear force and hardness values of the control had the highest value, however sausages containing 15% surimi-like material had the lowest value(p<0.05). Increased surimi-like material became darker in color. Although no differences in panel scores of flavor and off-flavor were observed, panellists prefer to select sausages having 15% surimi-like material(p<0.05). These results indicated that a surimi-like material, which was a myofibrillar protein extracted from pig hearts, could be used to manufacture emulsion-type sausage up to 15% to improve cooking yield and textural characteristics without color and flavor defects.

Ground lean pork was irradiated by an electron beam or X-rays to compare the effects of two types of radiation generated by a linear accelerator on the quality of Bologna sausage as a model meat product. Raw ground lean pork was vacuum packaged at a thickness of 1.5 cm and irradiated at doses of 2, 4, 6, 8, or 10 kGy by an electron beam (2.5 MeV) or X-rays (5 MeV). Solubility of myofibrillar proteins, bacterial counts, and thiobarbituric acid reactive substance (TBARS) values were determined for raw meat samples. Bologna sausage was manufactured using the irradiated lean pork, and total bacterial counts, TBARS values, and quality properties (color differences, cooking yield, texture, and palatability) were determined. Irradiation increased the solubility of myofibrillar proteins in a dose-dependent manner (p<0.05). Bacterial contamination of the raw meat was reduced as the absorbed dose increased, and the reduction was the same for both radiation types. Differences were observed only between irradiated and non-irradiated samples (p<0.05). X-ray irradiation may serve as an alternative to gamma irradiation and electron beam irradiation.

The aim of this study was to compare the effect of seawater to that of conventional salt (NaCl) on the technological properties of chicken emulsion sausages in a model system. Chicken sausages were prepared with seawater at three levels (10%, 15%, and 20%) in iced water (10%, 5%, and 0%, respectively) or with iced water (20%) and salt (1.2%). There was no difference in pH values and fat loss from emulsion stability between the two treatments. In general, with an increase in the amount of seawater, the water holding capacity (cooking yield and water loss), protein solubility (total and myofibrillar protein), and viscosity were increased. The addition of 20% seawater induced greater (p<0.05) water holding capacity, protein solubility, and viscosity compared to the control sample treated with salt, which was accompanied by an increase in the level of myosin heavy chain protein of samples with 10% and 20% seawater. Furthermore, addition of at least 15% seawater increased all of the main textural properties except for cohesiveness along with the moisture of sausage, whereas the fat and protein contents were decreased. Based on these results, the addition of ≥15% seawater to chicken breast sausage can induce equivalent or enhanced technological properties to those induced with salt, including water holding capacity, protein solubility, viscosity, and textural properties.

The quality of emulsion-type sausage manufactured using various amounts of red yeast rice powder (0, 1, 2, 3%) was investigated. Moisture and ash content increased, whereas the protein content decreased, upon increasing the red yeast rice powder content. The pH, lightness, and yellowness values of the uncooked and cooked samples decreased upon increasing the red yeast rice powder content. The redness of the cooked and uncooked samples containing 3% red yeast rice powder was higher than those of others. Cooking loss and emulsion stability of samples decreased upon increasing red yeast rice powder contents. Samples containing 2 and 3% red yeast rice powder showed lower viscosity than others. Sensory evaluation of samples increased with increas in red yeast rice powder content. Thus, red yeast rice powder improved the physicochemical and sensory properties of emulsion-type sausage.

The effects of red yeast rice powder on physicochemical properties of chicken thigh meat sausage were investigated. Control sausages were prepared with 1.2% NPS (nitrite pickling salt). Others samples were prepared with 1%, 2%, and 3% red yeast rice powder and 1.2% NaCl. With increasing red yeast rice powder content, the pH of uncooked and cooked samples generally decreased. In addition, lightness, and yellowness decreased with increasing content of red yeast powder (P<0.05), whilst redness increased with increasing content of red yeast powder in sausage samples (P<0.05). In addition, the samples with red rice powder showed more than 3 times higher redness compared to samples with 1.2% NPS, regardless of addition level. No significant difference in cooking yield among the treatments. The hardness of samples increased with increasing red yeast rice powder content, while the cohesiveness of samples containing red yeast rice powder was less than those observed for the control. Consequently, red yeast rice powder can be used to improve redness in sausages without adverse effect on cooking yield.

In order to study on the riboflavin content of common foods for Korean and the rates of destruction of riboflavin during cooking 26 kinds of the foods were selected and 3 kinds of menu were cooked by standardized method. For each food item and menu riboflavin content was measured by AOAC method. The experimental values of 13 kinds of food such as rice oak mushroom carrot squarsh tangle dried large anchovy apple(Fuji) dried laver ramyun pork soybean curd fried soybean curd and danmugi were almost consistent with food compo-sition values. Whereas those of 12 kinds of foods such as cabbage onion potato kimchi beef sausage dried medium anchovy hair tail soybean paste and egg were considerably different from food composition table values, up to now Alaskan pollack maize loaf bread hamburger bread etc have not been analyzed in food composition table, The rates of retention of riboflavin in menu 1, 2, and 3 cooked by standardized method were 24% 69% 46% respectively. The overally retention rate was in inverse proportion to the time of sunlight exposure during cooking.

The objective of this study was to evaluate effects of Gaeddongssuk powder (GP) on quality characteristics and shelf stability of emulsion sausages during storage. Proximate composition properties showed no significant differences in all treatment (p>0.05). Control showed the highest cooking loss while the treatment with GP showed decreased cooking loss depending on increasing GP content (p<0.05). Apparent viscosity of batter was increased as the amount of GP increased, whereas hardness of emulsion sausages was decreased with increasing GP level. In sensory evaluation, emulsion sausage with 0.1% GP resulted in the highest score in overall acceptability. The pH values of all treatments decreased at the early storage stage, followed by gradual increase. The lightness and redness of treatments were decreased when the level of GP was increased. However, the yellowness of sausages with GP were higher than that of control (p<0.05). The addition of GP inhibited lipid oxidation of emulsion sausages during storage depending on its level. The aerobic bacteria population and VBN was unaffected by addition of GP during the storage (p>0.05). Therefore, Gaeddongssuk powder up to 0.1% has a potential as a natural antioxidant for meat products because it can inhibit lipid oxidation of sausages without decreasing their sensory properties.

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.

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.
