The effects of dietary fiber extracted from pumpkin (pumpkin fiber) on physicochemical properties, textural properties, and sensory characteristics of chicken frankfurters were investigated. Chicken frankfurter was supplemented with pumpkin fiber at levels of 0, 1, 2, 3, and 4%. Adding different levels of pumpkin fiber affected the proximate composition of the chicken frankfurters (p<0.05), except for protein content. In addition of different levels of pumpkin fiber influenced the physicochemical and textural properties of the chicken frankfurters (p<0.05). The yellowness, viscosity, and hardness were higher in chicken frankfurters samples containing pumpkin fiber than those in the control (p<0.05). The results showed that chicken frankfurter samples with higher pumpkin fiber levels had lower lightness values (p<0.05), as well as less cooking loss, emulsion stability, and lower color scores (p<0.05) compared to those control without pumpkin fiber treatment. The chicken frankfurters with 2% and 3% pumpkin fiber had higher overall acceptability than that of the control (p<0.05). The results show that adding pumpkin fiber produced acceptable chicken frankfurters and improved their quality characteristics.

This study was performed to evaluate the quality of fermented sausages manufactured with processed sulfur-fed pigs. The fermented sausages were divided into two groups; one was manufactured with non sulfur-fed pigs (NP), the other one was made with processed sulfur-fed pigs (SP). No differences were found in moisture and fat contents (p>0.05) between NP and SP, but the protein and ash con-tents of SP were significantly higher than those of NP (p<0.05). The pH of SP was significantly lower than that of NP, and the water activity ($a_w$) of SP was significantly higher than that of NP after 14 and 21 d (p<0.05). The TBA (Thiobarbituric acid reactive substance) w value of SP was significantly lower than that of NP (p<0.05). The lightness and yellowness of NP were significantly higher than those of SP, whereas the redness of NP was lower than SP (p<0.05). The total plate count of SP was lower than that of NP (p<0.05). There was no significant difference in TPA (Texture profile analysis) between the two samples. SP showed significantly increased monounsaturated fatty acid (p<0.05) and decreased saturated fatty acid. Umami taste and richness in SP were significantly higher than in NP (p<0.05). Therefore, it is suggested that processed sulfur fed pigs may play a key role in enhancing the quality of meat products.

Emulsifiers are widely accepted ingredients in food & beverage applications owing to their functional properties. The multi-functionality of emulsifiers increases its adoption in end-use applications. Also, the growing demand of natural sources of ingredients and increase in demand for convenience foods and premium products have expanded the application areas of food emulsifiers in the food & beverage industries. Emulsifiers are increasingly used by food processors to make their food products more cost-efficient and robust, enabling them to endure the rigors of harsh processing.

The objective of this study was to examine the effect of adding various humectants (konjac, egg albumin, and isolated soy protein) on the properties of semi-dried chicken jerky. Jerky samples were prepared as follows: control with no humectants and treatments with 0.05, 0.1, and 0.2% of added humectants. Adding the humectants influenced the increase in pH, processing yields, moisture contents, water activity, mechanical tenderness, and sensorial properties (tenderness, juiciness, and overall acceptability) of chicken jerky. Additionally, the konjac treatment most improved the yields, tenderness, and sensorial traits, among the humectant treatments tested. Furthermore, adding 0.1% konjac during jerky manufacture resulted in similar quality properties as adding 0.2% konjac.

This study was conducted to investigate the physical and sensory properties of ice cream containing fermented pepper powder. Three ice cream formulas were manufactured: 1, control; 2, supplemented with 0.1% fermented pepper powder; and 3, supplemented with 0.2% fermented pepper powder. Formulas 2 and 3 had significantly higher viscosity and lower overrun than formula 1 (p<0.05). Additionally, ice creams supplemented with fermented pepper powder were harder and maintained their forms longer than the controls. 0.2% fermented pepper powder added ice cream had no pungency as much as that of control and overall sensory attribute was not significantly different from control. Therefore, ice cream containing fermented pepper powder maintained physical and sensory properties similar to the controls, and maintenance was better. It means fermented pepper powder ice cream can be utilized as the material of functional food (dessert).

The aim of this study was to evaluate the effects of tumbling condition (time and temperature) on the quality characteristics of restructured chicken breast ham. Tumbling conditions were 10, 30, and 60 min at 3 or $-3^{\circ}C$, respectively. After tumbling, quality characteristic regarding the treatments processed by each condition were measured. There were no significant differences in pH levels among tumbling time or temperature. Treatments involving 60 min of tumbling had significantly higher water holding capacity (WHC) than that tumbled for 10 min, but WHC was not affected by the tumbling temperature. The tumbling condition at $-3^{\circ}C$ for 60 min demonstrated the most effective cooking yields for restructured chicken breast ham. Myofibrillar protein solubility of treatments tumbled for 60 min had the highest value of all, regardless of tumbling temperature. The hardness of treatments tumbled at $-3^{\circ}C$ were lower than those at $3^{\circ}C$; however, the springiness of treatments tumbled for 60 min were significantly higher than those regarding the treatments tumbled for 10 and 30 min. Therefore, tumbling technology for 30 min or more at $-3^{\circ}C$ can produce restructured chicken breast ham of excellent quality.

The effects of adding goldenrod leaf powder (GLP) and goldenrod stem powder (GSP) (0.1% and 0.5%) to raw ground pork on antioxidant activity were examined. The following six treatment groups were used: Control (without antioxidant), GLP1 (with 0.1% GLP), GLP2 (with 0.5% GLP), GSP1 (with 0.1% GSP), GSP2 (with 0.5% GSP) and AS (with 0.05% ascorbic acid). The chemical compositions, pH values, instrumental color, conjugated diene (CD), free fatty acids (FFA) and thiobarbituric acid-reactive substance (TBARS) value were measured during 15 d of storage at chilled temperatures. The addition of GLP and GSP showed no effect on moisture, protein and fat contents of the samples. However, adding 0.5% GSP increased the ash contents of ground pork (p<0.05). The pH values of treated samples decreased until day 7, and then increased thereafter. The addition of GLP and GSP decreased the $L^*$ and $a^*$ values and increased the $b^*$ value (p<0.05). The CD, FFA and TBARS value of the control were higher (p<0.05) than samples containing GLP and GSP. The addition of GLP and GSP resulted in a significant decrease in CD, FFA and TBARS values. Overall, this study demonstrated that GL and GS could be used as an antioxidant of raw ground pork.

Abstract This study evaluated the effects of adding glasswort hydrate containing non-meat ingredient (GM, carboxy methyl cellulose; GC, carrageenan; GI, isolated soy protein; GS, sodium caseinate) on the quality characteristics of reduced-salt, reduced-fat frankfurters. The pH and color evaluation showed significant differences, depending on the type of glasswort hydrate added (p<0.05). In the raw batters and cooked frankfurters, the addition of glasswort hydrate decreased the redness and increased the yellowness in comparison with frankfurters without glasswort hydrate. The reduction in salt and fat content significantly increased cooking loss and decreased hardness, tenderness and juiciness (p<0.05). Glasswort hydrate containing non-meat ingredient improved cooking loss, water holding capacity, emulsion stability, hardness, and viscosity of reduced-salt, reduced-fat frankfurters. The GM treatment had the highest myofibiliar protein solubility among all treatments, which was associated with emulsion stability and viscosity. The GC treatment had higher values for all texture parameters than the control. In the sensory evaluation, the addition of glasswort hydrate with non-meat ingredient improved tenderness and juiciness of reduced-salt, reduced-fat frankfurters. GM, GC, and GI treatments improved not only the physicochemical properties but also the sensory characteristics of reduced-salt, reduced-fat frankfurters. The results indicated that the use of glasswort hydrate containing non-meat ingredient was improved the quality characteristics of reduced-salt, reduced-fat frankfurters.
