In this study, the Opuntia humifusa f. jeollaensis (Wanggasi-Chunnyuncho) fruit (WCF) was used as a source of viscous dietary fiber and color pigmentation in sausage production to improve quality characteristics, including cooking loss and emulsion stability. Control and treatment sausages were formulated with 0%, 1%, 5%, and 10% WCF powder, respectively, and the following quality measures were investigated: general composition, fiber content, cooking loss, emulsion stability, chromaticity, pH, texture, and sensory properties. The moisture, dietary fiber, and ash contents showed increasing trends (all p<0.05) with increasing concentrations of fruit powder. Conversely, crude protein and crude fat contents exhibited decreasing trends with increasing fruit powder concentrations (p<0.05). Moreover, both the moisture and dietary fiber contents affected cooking loss, water retention capacity, and the sausage texture, causing the cooking loss to decrease, while the water and oil retention capacity increased (p<0.05) with increasing concentrations of WCF powder. Furthermore, hardness exhibited a significant decreasing trend as the concentration of WCF powder increased (p<0.05). This finding suggested that both dietary fiber and viscous materials, along with the protein and moisture content, affected the product hardness. In addition, sensory evaluation of the WCF powder groups showed better results than did the control group, and the strongest results obtained for the group containing 5% fruit powder (p<0.05). Therefore, this study suggests that WCF powder improves the quality of emulsified sausages and can potentially be applied as a naturally-derived additive.

This study was carried out to investigate the effects of addition of citron peel powder(0.3%, 0.6%, 0.9%) on the quality characteristics of emulsion-type sausages. The pH, color, TBARS, residual nitrite content and textural properties were evaluated. The pH values of sausage containing citron peel powder were significantly(P<0.05) lower compared to those for control. The CIE $L^*$ and $a^*$ values of sausage containing citron peel powder tended to similar to control, but the CIE $b^*$ values were significantly(p<0.05) higher in the sausage containing citron peel powder. The TBARS values of sausage containing 0.9% citron peel powder were significantly(P<0.05) lower than those of control at 20, 40 and 60 days of storage. The residual nitrite content of sausage containing citron peel powder were significantly(P<0.05) lower compared to control. The hardness values of sausage containing citron peel powder were significantly(P<0.05) higher than those of control, but the cohesiveness, springiness and gumminess were significantly(P<0.05) lower in the sausage containing citron peel powder.

In order to improve or replace the direct addition method of nitrite and ascorbic acid, the effect of nitrite and ascorbic acid-derived gas addition on color development and physical characteristics in emulsified sausage was investigated. Nitrite (150 ppm) and ascorbic acid (450 ppm) were added directly to emulsion in the control group, but in the treatment group nitrite and ascorbic acid-derived gas was used for emulsion. In the control and treatment groups, pH values were higher than raw meat, but these values did not show significant change during the storage in both groups. In the meat color, lightness (CIE $L^*$) and redness ($a^*$) values of control and treatment groups were higher compared to raw meat. The treatment group has lower redness and higher yellowness ($b^*$) values than control group during the storage (p<0.05). However, lightness was not significantly different between control and treatment groups. The cook and storage loss values were significantly different between control and treatment groups (p<0.05), but the water holding capacity and shear force values were not significantly different between groups. These results showed that treatment of nitrite and ascorbic acid-derived gas has a similar effect to direct addition of nitrite and ascorbic acid on color development and physical characteristics in emulsified sausage. Also, these results showed that nitrite and ascorbic acid-derived gas addition may be a good possible alternative of nitrite and ascorbic acid using in emulsified sausage.

This study was designed to evaluate the quality comparison of emulsion-type sausages made from different Rhus verniciflua Stokes (RVS) sources. The pigs were fed a supplemented concentrate diet with a RVS supplement of $4\%$ feed for 5 weeks before slaughter. The RVS extract was prepared from 100g of RVS sawdust and 1L of distilled water for 48 hours. Emulsion-type sausages were made using lean meat or dietary RVS han1 lean $(51.07\%)$, ice water or RVS extract $(19.63\%)$, back fat $(26.60\%)$ and other additives $(2.70\%)$. The treated sausages were divided into non-dietary meat with water (T1, Control), dietary RVS meat with water (T2), non-dietary meat with RVS extract (T3), and dietary meat with RVS extract (T4). The crude fat was significantly lower (p<0.05) in dietary RVS meat-added sausages (T2, T4) than in control sausage (T1). The lightness ($L^{\ast}$) and redness ($a^{\ast}$) were significantly lower (p<0.05) in RVS extract-added sausages (T3, T4) during refrigerated storage. The $a^{\ast}$ value was higher (p<0.05) in T2 than in the other treatments. The VBN and TBARS values were significantly lower in RVS extract-added sausages (T3, T4) during refrigerated storage. The hardness, adhesiveness, gumminess, and chewiness were significantly lower (p<0.05) in T2 than in the other treatments. This results showed that feeding of RVS in diet and/or RVS extract had a significant impact on the quality of emulsion-type sausage. The RVS extract-added emulsion-type sausages (T3, T4) showed dark and reddish color although they were more effective in delaying the protein deterioration and lipid oxidation. Consequently, the sausage prepared from pigs fed $4\%$ RVS with water (T2) was more effective in increasing the $a^{\ast}$ value, textural properties, and delaying the protein deterioration, lipid oxidation than that without RVS in diet.

This study was conducted to evaluate the quality properties of emulsion-type pork sausages when pork fat is replaced with vegetable oil mixtures during processing. Pork sausages were processed under six treatment conditions: T1 (20% pork fat), T2 (10% pork fat + 2% grape seed oil + 4% olive oil + 4% canola oil), T3 (4% grape seed oil + 16% canola oil), T4 (4% grape seed oil + 4% olive oil + 12% canola oil), T5 (4% grape seed oil + 8% olive oil + 8% canola oil), and T6 (4% grape seed oil + 12% olive oil + 4% canola oil). Proximate analysis showed significant (p<0.05) differences in the moisture, protein, and fat content among the emulsion-type pork sausages. Furthermore, replacement with vegetable oil mixtures significantly decreased the ash content (p<0.05), increased water-holding capacity in emulsion-type pork sausages. Also, cholesterol content in T6 was significantly lower than T2 (p<0.05). In the texture profile analysis, hardness and chewiness of emulsion-type pork sausages were significantly (p<0.05) decreased by vegetable oil mixtures replacement. On the contrary, cohesiveness and springiness in the T4 group were similar to those of group T1. The unsaturated fatty acid content in emulsion-type pork sausages was increased by vegetable oil mixtures replacement. Replacement of pork fat with mixed vegetable oils had no negative effects on the quality properties of emulsion-type pork sausages, and due to its reduced saturated fatty acid composition, the product had the quality characteristics of the healthy meat products desired by consumers.

This study is conducted to evaluate the effects of the mixing ratio between pork loin and chicken breast for textural and sensory properties of emulsion sausages. Meat homogenates are prepared by using five mixing ratios between pork loin and chicken breast (100:0, 70:30, 50:50, 30:70, and 0:100), and the emulsion sausages are also formulated with five mixing ratios. The additions of chicken breast increase the salt soluble protein solubility due to high pH levels of chicken breast, thereby resulting in the reduction of cooking losses. In addition, the apparent viscosity of meat homogenates increase with increasing amounts of chicken breast. In terms of emulsion sausages formulated with pork loin and chicken breast, the addition of chicken breast above 50% may contribute to a softer and more flexible texture of emulsion sausages. For sensory evaluations, an increase in the added amount of chicken breast contributes to a rich umami taste and deeper flavor within the emulsion sausages, resulting in the high overall acceptance score for the formulation of 0-30% pork loin and 70-100% chicken breast. Therefore, the optimal mixing ratios between pork loin and chicken breast are 0-30% and 70-100% for enhancing the textural and sensory properties of emulsion sausages.

This effect of Monascus and Laccaic acid on the chemical composition, physical, texture and sensory properties of sausage were investigated during storage. Eight treatments (T) of sausage such as T1 (12 ppm sodium nitrite), while T2, T3, T4, T5, T6 and T7 were formulated with different ratios of Monascus/Laccaic acid: 63/7.0, 108/12, 135/15, 59.5/10.5, 102/18 and 127.5/22.5 ppm, respectively. The batch formulated without nitrite or Monascus and laccaic acid was served as control (C). The control sausages had higher pH values compared to the treated ones at 3, 10 and 28 d storage (p<0.05). After 10 d storage, the pH values decreased in treated sausage samples (p<0.05). The T1 and T4 presented the lowest yellowness and lightness values, respectively over the storage period. The redness values were increased as increasing Monascus and Laccaic acid amounts (T2-T4, T5-T7). The addition of Monascus and Laccaic acid had significantly higher hardness and springiness values (p<0.05) compared with the control in 3, 19 or 28 d storage. The results indicated that the addition of Monascus and Laccaic acid could improve the redness of the products.

This study was carried out for the development of assay method to quantify the soy protein content in meat homogenate, emulsion-type sausage and commercial meat products by Enzyme-linked Immunosorbent Assay(ELISA). The standard antigen was extracted before and after heat treatment. It was observed that the degree of reaction was not varied significantly according to the heating temperature. The recovery rate in meat homogenate and emulsion-type sausage was not varied significantly according to the heating temperature. The reaction was not interfered with fat and spices of the samples. Samples with 10% soy protein showed lower correlation than those with 2% and 5% soy protein. The recovery rate in commercial meat products showed difference individually. The correlation of some products with raw vegetable and wheat starch was relatively low.

This study estimated the effect of drone pupa meal (DPM) added as replacement of sodium nitrite (SN) and vitamin C (VC) on physico-chemical quality characteristics of emulsion-type sausages. Samples were prepared either with 150 ppm SN+200 ppm VC (control); 75 ppm SN+100 ppm VC+6.015% DPM (T1); or 12.03% DPM (T2) and then stored at $4^{\circ}C$ for 30 days. The pH value decreased (p<0.05) with increase in the levels of DPM. Moisture and protein content decreased (p<0.05) but fat and ash content increased (p<0.05) with higher levels of DPM. T1 and T2 had higher (p<0.05) saturated fatty acids content and lower (p<0.05) unsaturated and polyunsaturated fatty acids content compared to the control. Lower (p<0.05) $L^*$ and $a^*$ values and higher (p<0.05) $b^*$ and $h^{\circ}$ values were exhibited in the T1 and T2 than in the control; and $C^*$ value was the lowest (p<0.05) in T2. The TBARS content was the highest (p<0.05) in T2, especially, 2 times higher (p<0.05) than in the control. T1 and T2 had harder (p<0.05) texture compared to the control. These findings suggest that the DPM has no replacement effects against SN and VC in emulsion-type sausage, but it has negative effects on color, lipid oxidation stability, and texture.

The aim of this study was to investigate the effects of pork skin gelatin on the physicochemical properties (pH, CIE color value, water holding capacity, cooking yield, viscosity, proximate composition, and texture profile analysis) of emulsion-type sausage. Emulsion-type sausages were manufactured with 0% (control), 1%, 3%, and 5% pork skin gelatin. Moisture contents of samples containing 3% and 5% pork skin gelatin were significantly higher than those of the control and samples containing 1% pork skin gelatin (P<0.05). Protein contents were the highest in samples containing 5% pork skin gelatin (P<0.05). The pH values of uncooked and cooked samples increased with increasing pork skin gelatin level (P<0.05). The lightness and yellowness values of cooked samples containing pork skin gelatin were higher than those of the control (P<0.05). In addition, redness values of cooked samples containing 3% and 5% pork skin gelatin were significantly lower than those of the control and samples containing 1% pork skin gelatin (P<0.05). Water holding capacity (WHC) was the lowest in control, and samples containing 3% and 5% pork skin gelatin had significantly higher WHC compared to the other samples (P<0.05). Cooking yield of samples increased with increasing concentration of pork skin gelatin (P<0.05). Samples containing 3% and 5% pork skin gelatin showed higher viscosity than the control and sample containing 1% pork skin gelatin (P<0.05). Springiness, cohesiveness, and chewiness of samples were not significantly different among the samples. Hardness values of the control and sample containing 1% pork skin gelatin were lower than those of other samples (P<0.05), and samples containing 5% pork skin gelatin had the highest hardness (P<0.05). Gumminess of sample containing 5% pork skin gelatin was significantly higher than that of the control (P<0.05). The results show that pork skin gelatin could improve the potential of emulsion-type sausage physicochemical properties.
