This study was performed to investigate the effect of Gleditsia sinensis Lam. extract on the physicochemical properties of emulsion-type pork sausages during storage at $10^{\circ}C$ for 4 wk. Treatments were as follows: (C, control; T1, sodium ascorbate 0.05%; T2, Gleditsia sinensis Lam. 0.05%; T3, Gleditsia sinensis Lam. 0.1%; T4, Gleditsia sinensis Lam. 0.2%; T5, Gleditsia sinensis Lam. 0.1% + sodium ascorbate 0.05%). The values of pH, moisture content, lightness, redness, and sensory attributes were all significantly decreased, while the yellowness, chroma, hue angle, and texture properties were increased during storage with increase of the Gleditsia sinensis Lam. extract added. In addition, the antioxidant activity and antimicrobial activity in the sausages displayed significant increases (p<0.05). Therefore, although it was concluded that the addition of Gleditsia sinensis Lam. extract is not effective for improvement of the physical properties compared to chemical additives in sausages, it could be applied to meat products as a natural preservatives.

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 dealt with the use of quinoa flour (QF) or teff flour (TF) as partial beef fat replacers in the formulation of emulsion-type sausages. A control (C) group was manufactured with 20% beef fat, while the other three groups were formulated with 10% beef fat plus 5% QF (Q), 5% TF (T), and 2.5% QF+2.5% TF (QT). Water-holding capacity of the emulsions was higher in Q (81.81%), T (82.20%), and QT (84.10%) samples than in C (64.83%) samples. Total expressible fluid and expressible fat were the lowest in Q and T samples, indicating the highest emulsion stability of those groups. Incorporation of QF and TF into formulations increased moisture and carbohydrate contents while decreased fat and energy values. Besides, the use of QF was effective to increase protein and dietary fiber contents. T sausages had lower luminosity (L^⁎) and higher yellowness (b^⁎) than C sausages, whilst Q sausages did not result in significant color changes. Higher cook yield values were recorded in Q (97.96%), T (98.21%), and QT (98.15%) samples compared with C (96.44%) samples. Inclusion of QF and TF to formulation led to lower hardness and gumminess, while utilization of TF was also effective to decrease chewiness. Consequently, healthier emulsified sausages were obtained by the inclusion of QF or TF that could decrease the fat content more than 50% without sacrificing overall quality, bringing advantages by quinoa over teff for increasing nutritional value and leading minimal modifications on color and texture.

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.

This study was conducted to investigate the effects of raw material ratio on the physicochemical characteristics of emulsion-type pork sausages. Experiment design was divided into 12 treatments, based on protein level (P), fat level (3P, 3.5P, and 4P), and water level (4P+10, 4P+15, 4P+20, and 4P+25). The pH and shear force values were significantly higher in T7 (3.5P fat and 4P+20 water) than those of other treatments. The lightness and redness were greatly reduced by increasing the quantity of water. The treatments containing 3P fat and 4P+20 water had the highest values of cohesiveness, springiness, gumminess, and chewiness. On the whole, when the protein (P) and fat (3P, 3.5P, 4P) levels were fixed, an increase over the appropriate moisture level deteriorated many physicochemical characteristics.

Beef fat was replaced with cold press pumpkin seed oil (PSO; 0%, 5%, 15%, and 20%) in the production of bologna-type sausages. A value of pH, water-holding capacity (WHC), jelly-fat separation, emulsion stability and viscosity values were determined in meat batters. Thiobarbituric acid reactive substances (TBARS), color, and textural characteristics (TPA, shear test, penetration test) were determined in end-product at 1, 7, 14, 21, and 28 days of storage at 4℃. The pH values were varied between 6.06 and 6.08. With the increase in the level of PSO in meat batters, there was a significant increase in WHC, jelly-fat separation and viscosity values (p<0.05) while a significant decrease in emulsion stability (p<0.05). TBARS values of sausages were found to be significantly higher than in the control group (p<0.05), and this trend continued during storage. Increasing of PSO level were caused a significant increase in L* and b* values while a decrease in a* value (p<0.05). Hardness, adhesiveness and chewiness values were significantly reduced whereas cohesiveness and resilience values increased (p<0.05). Maximum shear force and work of shear was significantly decreased as the level of PSO increased (p<0.05). Hardness, work of penetration and the resistance during the withdrawal of the probe values (penetration tests) increased significantly with the increase in the level of PSO (p<0.05). These results indicate that PSO has potential to be use as a replacement of animal-based fats in the production of bologna-type sausages.

A computeized least-cost formulation program was applied to process emulsion-type sausages. The input data in formulation were utilized with the database which had been established in the previous study. The formulation results may provide Korean meat processors with actual examples. Meat-grade system made these examples more useful. The results of manufacturing test were as follows. The actual cohesiveness from manufactured sausages didn't correspond to the predicted values, but increased as the predicted values increased. These gabs caused by the different processing conditions between the model system and the actual processing. Hardness as well as cohesiveness could be used as the desirable index of a sausage texture. Comparing the cohesiveness and hardness of commercial frankfurters with those of test sausages, bind value constraint of $0.16{\sim}0.17$ in this test formula can be utilized for an actual formulation.

The objective of this study was to evaluate the quality of emulsion-type sausage where part of the pork was substituted with horse meat during manufacturing. Three treatments of sausages were manufactured by replacing pork with 0, 50 and 100% horse meat. After manufacturing, sausages were vacuum-packaged and stored 4℃ for 1 day. An increase in horse meat resulted in higher moisture, protein content, and pH values, and lower fat content of sausage(P<0.05). However, no significant effects were observed on texture characteristics and sensory attributes of sausage. The horse meat sausage had higher K, Fe, Zn, Cu, saturated fatty acid contents than 0% horse meat level. Based on the results, it can be concluded that horse meat can be used as a meat replacer in the manufacture of emulsion-type sausages up to a level of 100%.

In this study, the effects of Corchorus olitorius powder on the quality characteristics of emulsion type sausages during storage at $4^{\circ}C$ for 28 days was evaluated. Sausages were produced containing 0.5%, 1.0% and 1.5% C. olitorius powder. The pH values of sausage containing C. olitorius powder were higher than the control during 28 days of storage. The L and a values of sausage containing C. olitorius powder significantly decreased with increasing C. olitorius powder content; however, the b values significantly increased. The volatile basic nitrogen (VBN) and nitrite content of sausage containing C. olitorius powder were lower than that of the control. Especially, the VBN and nitrite content of sausages containing 1.5% C. olitorius powder were significantly lower compared to the control. In addition, sausages with $0.5{\sim}1.0%$ C. olitorius powder had higher hardness, cohesiveness, gumminess and brittleness than the control. In regards to the sensory evaluation, sausages containing 0.5% C. olitorius powder had the highest overall acceptability. Therefore, these results suggest that it may be possible to manufacture sausages containing 0.5% C. olitorius powder to help improve the overall quality of sausage.

The objective of this study was to investigate the effects of canola and flaxseed oils on the physicochemical properties and sensory quality of emulsion-type sausage made from spent layer meat. Three types of sausage were manufactured with different fat sources: 20% pork back fat (CON), 20% canola oil (CA) and 20% flaxseed oil (FL). The pH value of the CA was significantly higher than the others (p<0.05). The highest water holding capacity was also presented for CA; in other words, CA demonstrated a significantly lower water loss value among the treatments (p<0.05). CA had the highest lightness value (p<0.05). However, FL showed the highest yellowness value (p<0.05) because of its own high-density yellow color. The texture profile of the treatments manufactured with vegetable oils showed higher values than for the CON (p<0.05); furthermore, CA had the highest texture profile values (p<0.05) among the treatments. The replacement of pork back fat with canola and flaxseed oils in sausages significantly increased the omega-3 fatty acid content (p<0.05) over 15 to 86 times, respectively. All emulsion sausages containing vegetable oil exhibited significantly lower values for saturated fatty acid content and the omega-6 to omega-3 ratios compared to CON (p<0.05). The results show that using canola or flaxseed oils as a pork fat replacer has a high potential to produce healthier products, and notably, the use of canola oil produced characteristics of great emulsion stability and sensory quality.
