The objective of this study was to evaluate quality characteristics of low-nitrite emulsified-sausages (ESs, < 75 ppm) containing paprika oleoresin solution (POS) for replacing sodium nitrite (NaNO2). Pork ESs were prepared with four treatments (reference (REF), 150 ppm NaNO2; TRT1, 0 ppm NaNO2 + 0.1% POS; TRT2, 37.5 ppm NaNO2 + 0.1% POS; and TRT3, 75 ppm NaNO2 + 0.1% POS). The physicochemical and texture properties, microbial counts, residual nitrite and thiobarbituric acid reactant substances (TBARS) were measured during refrigerated storage of 35 days. Although TRT2 and TRT3 had lower levels of NaNO2, they had higher redness and yellowness than REF (p < 0.05). Microbial counts of total bacterial counts and Enterobacteriaceae of TRT2 and TRT3 were similar to those of REF (p > 0.05). Expressible moisture percentages (EM, %) of TRT2 and TRT3 were lower than those of REF (p < 0.05). TBARS values of TRT2 and TRT3 were not different from those of REF (p > 0.05). Among treatments, TRT1 had the highest TBARS values (p < 0.05). In conclusion, 0.1% POS in combination with 37.5 ppm NaNO2 would have quality characteristics similar to those of REF. Therefore, approximately 3/4 of the initial nitrite level could be replaced with 0.1% POS, and eventually developed healthier pork products.

Meat industries utilize plant material such as celery in cured meat products. Extraction of valuable bioactive compounds, nitrates and nitrites often involves processes that increase cost or lack sustainability. Thus, this study investigated the effect of ball-milled celery powders (CP) on the physicochemical, antioxidant, and antimicrobial properties along with curing efficiency in comminuted meat product. Pork sausages loaded with CPs with different average particle sizes: 265 ㎛ (T1), 68 ㎛ (T2) and 7 ㎛ (T3) were compared to those added without and with sodium nitrite (150 ppm). The a⁎ values were increased for sausages with larger particle size. The L⁎ values decreased for all CPs. Residual nitrite for all particle sizes increased in the earlier stages and decreased at the end of storage period. The curing efficiency also increased for larger size particles with an increase until day 9 followed by a gradual decrease. Superfine CP had a tendency to improve the antioxidant activities. The antimicrobial activity of CPs was not comparable with nitrite added sausages. The textural parameters remained unaffected by particle size. Thus, instead of extracts or juices, micronized CPs could be used to improve the antioxidant activities and curing efficiency of label friendly reformulated meat products.

The long-term storability of home-made dry sausage and ham in terms of peroxide value and thiobarbituric acid value, the effects of nitrite and NaCl contents on the deterioration of the products and the public acceptance of dry ham were studied. The results of this study are as follows: 1. Because the storability of the dried meat products is mainly affected by the fat rancidity of the fat content, POV of 10 was assumed the critical point of storability. The sample dry sausage used in this experiment has lost its storability within a ripening period of 5 weeks. And dry ham was lost its peculiar relish within 50 days. 2. The variations of the NaCl contents of the dry products were reflected in the ripening process. The correlation coefficient between the variations of the NaCl contents and the decrease in the weight of the dry ham was 0.85. 3. The survey of public taste for dry ham was conducted on 35 college students, who think it a bit tasteful or tasteless account for 66% of the total and those who think it a simple relish account for 60%, thus indicating that the dry ham still remains far away from the dining table.

This study was conducted to investigate the effect of duck and pork meat mixing ratio on quality characteristics of emulsion type sausage at $4^{\circ}C$ during 5 weeks. Treatments on the basis of the meat content were subjected to 100% duck meat (T1), 100% pork meat (T2), 50% duck meat + 50% pork meat (T3), 40% duck meat + 60% pork meat (T4), and 30% duck meat + 70% pork meat (T5). The moisture content was significantly (p<0.05) higher in TI sample but significantly (p<0.05) lower in T2 sample than those in comparison to the other treatments. Crude protein and fat content were significantly (p<0.05) higher in T2 sample compared to the other treatments. CIE $L^*$value was significantly (p<0.05) lower in T1 sample than those of other treatments until 5 weeks of cold storage. CIE $a^*$value was significantly (p<0.05) higher in T1 sample but significantly (p<0.05) lower in T2 sample than those in comparison to the other treatments until 5 weeks of cold storage. Hardness was significantly (p<0.05) higher in T4 sample compared to the other treatments during all cold storage. Cohesiveness was significantly (p<0.05) higher in T5 sample compared to the other treatments until 2 weeks of cold storage. The results of sensory evaluation showed that the meat flavor, taste and texture were significantly (p<0.05) lower in T5 sample compared to the other treatments whereas no difference among treatments except T5 sample. Overall acceptability was significantly (p<0.05) lower in T5 sample compared to the other treatments. Therefore, these results suggested that the ratio of 40% duck meat and 60% pork meat is appropriate levels for hardness and palatability when manufacturing emulsion type sausage with duck meat.

Discoloration by heating and gamma-radiation of aqueous solutions of two coal-tar food dyes used in meat products was observed. Tartrazin with sodium tri-polyphosphate or cinnamon oil was slightly discolorized by heating at $75^{\circ}C$, but Amaranth was comparatively resistant. Effect of gamma rays of coal-tar food dyes was generally increased with irradiation doses, and especially by the addition of sodium tri-polyphosphate and cinnamon oil. This tendency was higher in Tartrazin than Amaranth. The addition of sodium nitrate and ascorbic acid, and storage at low temperature, however, seems to be effective in decreasing the discoloration of irradiated solutions.

Emulsion-type sausages were manufactured to investigate the effects of CLA-vegetable oils and CLA-lard on quality characteristics of emulsion-type sausage. Each treatments replaced pork back fat with CLA-corn oil (CLA-CO), CLA-safflower seed oil (CLA-SSO) and CLA-lard (CLA-LD) were stored during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. The changes in physico-chemical properties, texture, thiobarbituric acid reactive substances (TBARS), fatty acid composition and CLA content of each treatments were measured during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. During storage, pH of control showed higher pH value than that of CLA-vegetable and CLA-lard treatments. The pH values of all treatments was significantly low at storage 14 days (p<0.05). The color L* and a*-value of all the treatments was not significantly changed with the storage periods. Color b*-value of CLA-treatments was higher than that of control during the storage period. Fatty acids composition was changed by addition of CLA-vegetable oils and CLA-lard. All kinds of fatty acids composition were decreased with CLA replacements than that of the control. Whereas linolenic acid content extremely increased by replacement of CLA-vegetable. CLA content of CLA-treatments was extremely increased than that of the control. The cohesiveness, springness, gumminess and brittleness of CLA-LD treatment was significantly higher (P<0.05) than that of the other treatments. The TBARS value of all treatments were significantly increased (P<0.05) as the storage period was passed. TBARS of sausage products containing CLA-CO was the lowest. Summing up the a forementioned results, emulsion-type sausage manufacturing with CLA-vegetable oil and CLA-lard was not affected in physico-chemical properties and texture characteristics. Also, it may be assumed that the high quality sausage can be manufactured with the extent of storage period and CLA accumulation.

The objective of this study was to determine the effect of the meat from spent laying hen on the shelf-life and physicochemical properties of emulsified sausage. Four types of sausage were made: 0% (Control), 10% (T1), 20% (T2) and 30% (T3) of spent hen meat added. Each sausage type was tested in triplicate. The addition of spent hen meat resulted in decreased crude fat and cooking loss, and increased WHC (water holding capacity), CIE $a^*$ and hardness. Values for crude fat and cooking loss were significantly decreased by the addition of spent laying hen meat relative to the control (P<0.05). Especially, T3 was significantly (P<0.05) decreased compare to other treatment groups. Spent laying hen meat addition had no significantly effects on moisture, crude protein, crude ash, pH, WHC, TBARS (thiobarbituric acid reactive substance) values, shear force, total plate counts (TPC), CIE $L^*$ and $b^*$ values. In conclusion, this study demonstrates that the addition of spent laying hen meat to emulsified sausages tended to improve sausage quality.

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.

Effects of replacing pork backfat with a combination (ICM) of isolated soy protein (ISP), carrageenan, and maltodextrin, or with ICM +olive oil, on the quality characteristics of sausages were investigated. Both treatments had lower fat content (p<0.05), but higher protein and moisture contents than the control (p<0.05). The fat content of low-fat sausage containing the ICM was increased on day 30 compared to day 1 and 15 (p<0.05), and that of ICM+olive oil was increased after day 15. The water holding capacity of ICM was lower than the control through day 30 (p<0.05). The ICM+olive oil had a lower cooking loss than ICM on day 1 and 15 (p<0.05). On day 1, the ICM had lower lightness and higher redness values than the control (p<0.05), and the ICM+olive oil had a higher yellowness value than the control and ICM (p<0.05). Both treatments presented higher hardness, cohesiveness, gumminess, and chewiness values than the control (p<0.05). The lipid oxidation values of both treatments were lower than the control on day 15 and 30 (p<0.05), and those were affected by the addition of olive oil. The ICM was rated higher for sensory color and overall acceptability than the ICM+olive oil (p<0.05).
