The objective of this study was to assess the sensory-related characteristics of the broth and porridge of ready-to-eat (RTE) ginseng chicken soup (Samgyetang) with sucrose stearate added at various concentrations (0.1%, 0.2%, and 0.3%) during storage at $25^{\circ}C$ for 12 mon. Scores indicating the lightness and size of fat droplets in the broth increased during storage as the sucrose stearate concentration increased, while the clarity scores decreased until 9 mon and the taste scores decreased throughout the storage period (p<0.05). The porridge lightness increased as the concentration of sucrose stearate increased after 6 mon (p<0.05), while scores indicating the softness and vividness were higher for treated samples with sucrose stearate than for the control group after 3 mon, despite a lack of significant differences among treatment groups (p>0.05). The taste scores were lower for treated porridge samples than for the control group (p<0.05), even though no significant differences were observed among the treatment groups (p>0.05). The addition of sucrose stearate to the RTE Samgyetang broth improved the lightness (CIE $L^*$) value of the broth and various sensory palatability parameters, including the color and fat droplet size of the broth and the softness and vividness of the porridge, despite reductions in broth clarity and taste scores for the broth and porridge during storage.

This study investigated the effect of traditional medicinal plants on the quality characteristics of Samgyetang breast meat and broth. The traditional medicinal plants used in this study were roots of Panax ginseng, Codonopsis lanceolata, Platycodon grandiflorum, Salvia miltiorrhiza, Adenophora triphylla, and Allium hookeri. There was no significant difference (P>0.05) in the moisture, protein, ash content, water holding capacity, and cooking loss of Samgyetang meat with the addition of traditional medicinal plants. The color values (lightness, redness, and yellowness) of Samgyetang meat and broth were significantly different (P<0.05); the 2-thiobarbituric acid reactive substances and shear force of Samgyetang meat were significantly different (P<0.05); and the pH, turbidity, and viscosity of Samgyetang broth were also significantly different (P<0.05) with the addition of traditional medicinal plants. In the overall acceptability of Samgyetang meat, the addition of S. miltiorrhiza showed the highest score compared to that of other treatments (P<0.05). Thus, the addition of traditional medicinal plants in the production of Samgyetang were found to affect the lipid rancidity beneficially with plant species when compared to Samgyetang with Panax ginseng. In conclusion, with the development of Samgyetang using S. miltiorrhiza, it will be possible to develop products with superior quality characteristics in antioxidant, shear force, and overall acceptability.

The effects of filling temperatures of broth and degassing method on the residual oxygen content and gas composition in the pouch and physical strength of packaging material for Samgyetang depending on the contamination of broth on the sealing layer and sterilization process were investigated. The residual oxygen content in the broth and the oxygen proportion in the headspace of package were decreased with the increase of broth temperature at filling into the pouch from 50 to 100. When the products were packaged as air-contained (Air), manually squeezed the upper side of package out to minimize the headspace (Degas) and flushed with nitrogen gas ($N_2$-Flushing) while maintaining the broth temperatures of Samgyetang at 50 or 85. The residual oxygen content and oxygen proportion were increased in the order of $N_2$-Flushing

This study was conducted to investigate the awareness and preference regarding Korean Samgyetang by the Chinese. An online survey was conducted to determine the awareness regarding Korean Samgyetang among the local Chinese, and a consumer preference test was performed to design the recipe of Samgyetang for Chinese students in Korea during April 2016. The results of the online survey showed that 88.2 % and 88.4 % of local Chinese men and women, respectively, were aware of Korean Samgyetang. Samgyetang recognition by the local residents of China was the highest in the Hubei region that includes Beijing. Traditional Samgyetang received the highest preference and Samgyetang with mung bean received the lowest preference in the preference test based on the Samgyetang type. In consumer preference tests among Chinese students, Samgyetang with broth of chicken feet (Sample-1) and Samgyetang with medicinal herbs (Sample-3) showed high acceptability than Samgyetang in water (Sample-2) in terms of the overall sensory properties. According to the results of the electronic tongue, Sample-1 showed a high value in terms of the strength of the saltiness and Sample-3 showed a high value in terms of the strength of bitterness and sweetness. Sample-2 showed a high value in terms of the strength of umami and sourness.

This study was performed to investigate the effects of taste-related compounds and antioxidatve profiles of retorted samgyetang made from fresh and dried Cordyceps militaris (C. militaris) mushrooms. A total of 48 carcasses were prepared from commercial broilers (CB; Ross, 4 weeks old) and randomly distributed into eight different treatments. Each treatment group consisted of 6 chicken carcasses made with the addition of broth in different condition and concentration of C. militaris mushrooms. The addition concentration was based on the broth volume (v/w) under either fresh or dried conditions ranging from 0% as a control to 1%, 2%, and 3% of C. militaris mushrooms. C. militaris mushrooms contributed to an improvement of meat tenderness and the antioxidative profile that led to a greater suppression of lipid oxidation. The addition of C. militaris mushrooms at 2% could also enrich the flavor and taste-related compounds, particularly the increase in 5'-AMP and umami-related free amino acid compounds, L-aspartic acid and L-glutamic acid. Different addition forms of C. militaris mushrooms, particularly fresh or dried mushrooms, had only small effects on bioactive compounds, where the dried addition could possibly enrich samgyetang broth with higher cordycepin and adenosine contents than the fresh addition. Besides, the addition of C. militaris mushrooms in the dried form could also contribute to a higher antioxidative profile. Eventually, the addition of C. militaris mushrooms with a minimum addition of 2% contributed to an improvement of meat quality, antioxidative profile and flavor improvement of samgyetang.

This study was conducted to determine the $F_0$-values of a retort machine at different locations and to evaluate the effects of these $F_0$-values on various quality characteristics of retorted Samgyetang samples. Samples were divided into three groups based on $F_0$-values-T1, 10~20; T2, 20~30; T3, >30. Mineral content in Samgyetang broth and breast meat mostly increased with increasing $F_0$-values. In general, the free amino acid values, hardness, and springiness, except for bone springiness, of Samgyetang decreased significantly at higher $F_0$-values. Protein content of meat and broth of the treated samples were significantly lower than that of the control. An increase in the digestion rate of meat and porridge, as well as the turbidity of the broth was observed in most of the treated samples with increasing $F_0$-values. With increasing $F_0$-values, the $L^*$ and $b^*$ values of meat and the $b^*$ values of broth tended to increase, while the $a^*$ value of broth increased significantly. Electronic nose analysis revealed different flavor patterns for samples treated at different $F_0$-values. For sensory traits, samples treated with higher $F_0$-values tended to receive lower evaluations. Particularly, the color and texture of T3 samples were lower than those of T1 and T2 samples. In conclusion, to improve the quality of Samgyetang, the efficiency and optimization of retort machines as well as the standardization of sterilization techniques are needed.

The effects of sucrose stearate at various concentrations (0.1%, 0.2%, and 0.3%, w/v) on the physico-chemical characteristics of ready-to-eat (RTE) Samgyetang were investigated during storage at $25^{\circ}C$ for 12 mon. Over the storage duration, the addition of sucrose stearate had no significant effects on the proximate composition of Samgyetang, including meat, broth, and porridge, or the hardness and spreadability of the porridge, although it resulted in significantly higher CIE $L^*$ values for the porridge. The CIE $L^*$ values of Samgyetang porridge with added sucrose stearate increased until 9 mon, while the control decreased until 6 mon, and the values for both changed insignificantly thereafter. The breast meat of Samgyetang treated with sucrose stearate showed higher percentages of polyunsaturated fatty acid after 3 mon and lower percentages of monounsaturated fatty acid after 6 mon compared to the control (p<0.05), while no significant differences were observed with the different sucrose stearate concentrations (p>0.05). The overall sensory acceptability scores were higher at sucrose stearate concentrations of 0.2% or 0.3% after 6 mon and at 0.1% after 9 mon compared to those of the control.

In this study, the effect of sodium chloride (salt) concentration and phosphate on the quality properties of samgyetang was investigated. Increasing the salt concentration by 0.5% increased the moisture and ash content, salinity, water holding capacity (WHC), and thiobarbituric acid reactive substances (TBARS), whereas the protein content, pH, cooking losses, and shear forces were decreased. Addition of phosphate to the brine increased the pH and WHC, but decreased the TBARS, cooking losses, and shear forces. In a sensory evaluation, the scores for flavor and overall acceptability were the highest when the salt concentration of the brine was 2.0%. Overall, this study shows that the salt concentration and addition of phosphate to the brine of samgyetang substantially influences the overall quality of the chicken breast. Based on quality measurements and sensory scores, a 2.0% salt concentration with the addition of phosphate appear to be the most suitable conditions for the manufacturing of marinated samgyetang.

This study was conducted to develop and compare Samgyetang broth from extract of pre-treated chicken feet. Chicken feet were subjected to non-heating (control), heating at $70^{\circ}C$ for 12 h in a hot air dryer, and heating at $180^{\circ}C$ for 1 h in an oven. The heat-treated chicken feet were extracted at $121^{\circ}C$ for 1 h and 2 h, respectively. The extract was placed in a pouch with whole chicken carcass ($470{\pm}10g$). The sealed Samgyetang retort was made according to the industrial method. The pH of the extract from preheated chicken feet was lower than that extracted from fresh chicken feet. The Thiobarbituric Acid Reactive Substances (TBARS) value of the preheated chicken feet extract was significantly lower (P<0.05) than that of fresh chicken feet extract, but there were no significant differences among the broths. As the extraction time increased, the pH and TBARS value decreased in the extract (P<0.05) but increased in the broth (P<0.05). According to the sensory evaluation test, the extract from 1 h hot air heating and drying was significantly better in appearance, aroma, and overall preference than the other treatments (P<0.05). The GC-MS results showed that benzaldehyde and benzothiazole, which are widely known to give meat and nuts flavor, were detected in those treatments (P<0.05). The Samgyetang broths prepared from 1 h hot air heating and drying extract were significantly higher in the overall acceptability according to the sensory test (P<0.05). In summary, the quality of retort Samgyetang broth can be improved by adding chicken feet extract which is subjected to heating and drying for 1 h.

This study investigated the possible improvement in the antioxidative status and quality characteristics of ready-to-eat (RTE) Samgyetang after adding various black garlic (BG) extracts. The antioxidant activity, total phenolic content (TPC), total flavonoid content (TFC), meat quality indexes, and lipid oxidation rates were measured after receiving one of five different treatments consisting of conventional Samgyetang broth as a negative control, raw garlic (RG) extract as a positive control, BG, oven-dried BG, and maltodextrin-encapsulated BG extract as treatments. Employing retort cooking, fat trimmed carcasses were added to the initially prepared broth together with a phenolic extract that was set at 5% (w/w). A significant intensification of red and yellow color was observed in breast and thigh meat treated with BG extracts, regardless of pretreatment, compared to the negative control and RG. The moisture percentage was affected by the addition of BG extracts, where the encapsulation group retained the highest water content after retorting. In terms of antioxidative status, maltodextrin-encapsulated BG extract was as effective as an oven-dried extract to scavenge free radicals and showed the highest score among samples (p<0.01). The concentration of TFC was found to be the highest and did not differ between encapsulation and oven-dried groups, followed by BG, RG, and the negative control. However, the addition of encapsulated BG extract was the most effective in delaying the formation of malondialdehyde among the samples. Therefore, pre-treatment of BG extract through encapsulation is recommended to develop a higher antioxidative status and quality characteristics of Samgyetang.
