  • The objective of this study was to evaluate the effect of different levels of palm kernel meal (PKM), an alternative to corn, on the quality of pork. A total of 72 crossbred pigs ([Yorkshire ${\times}$ Landrace] ${\times}$ Duroc) were assigned into four dietary treatments (PKM level of 0, 4, 8, or 12%). After 12 wk, one pig of median weight in each pen was selected and slaughtered to analyze meat quality. The color, free radical scavenging activity, lipid oxidation, texture, composition of fatty acids, and sensory qualities of pork loin were evaluated post slaughter. When the levels of PKM in the diet increased, the $L^*$-value of pork loin decreased, whereas $a^*$-value and total saturated fatty acids increased. 2-Thiobarbituric acid reactive substance (TBARS) values of pork loin were lower in groups treated with 8 and 12% PKM than in the control group at day 0; this difference, however, was not observed at day 3 and 7. The results of texture analysis showed that increasing the PKM ratio decreased hardness, chewiness, and springiness at day 7. The sensory test, however, indicated no differences between the control and treated groups. These findings show that finisher pigs could tolerate PKM as a replacement for corn; PKM did not negatively affect the quality of pork, indicating that it can be utilized as feed.

  • Several quality parameters affecting Alaska pollack, Theragra chalcogramma, were measured and modeled kinetically under storage at different temperatures: the K-value, trimethylamine (TMA), volatile basic nitrogen (VBN), Torry meter, pH, acid value (AV), total viable cell count (TVC), and colony forming units (CFU) of Pseudomonas spp. The off-flavor development time (ODT) was also measured using the R-index sensory test and modeled kinetically. Among the quality parameters, the CFU of Pseudomonas spp. was an indicator of the ODT according to a similarity in the Arrhenius temperature dependence, which was derived as a criterion mathematically. The temperature dependence was represented by the Arrhenius's activation energy ($E_a$). On comparing the $E_a$ of the quality factors and the ODT, the similarity in the temperature dependence was found to be high in the order Pseudomonas spp., pH, VBN, TVC, K-value, TMA, AV, and Torry meter. Therefore, Pseudomonas spp. was identified as the primary indicator of ODT.

  • The purpose of current study is to develop and estimate a proposed model that explains the potential relationships among food quality, experiential value, price fairness, image, satisfaction, and behavioral intention in context of water park. In addition, the study will verify how these factors link to each other. Results show that food quality is a significant antecedent of experience value, price fairness, water park image. Also, the experiential value and water park image influence on visitors' satisfaction. Last, the satisfaction is critical predictor of behavioral intention. These findings will contribute to understand the consumers' perception about water park, and how derives the customer satisfaction and behavioral intention. In sum, present study will serve insights for industry marketers and managers in water park segment.

  • Identifying quality attributes with the greatest value to the residents is important if the Continuing Care Retirement Community (CCRC) is to increase the frequency of residents' dining. However, it is not known which specific attribute is relatively more important than others to evaluate foodservice. The purpose of this study is to identify the relative importance of food and service quality attributes in the evaluation of foodservice in CCRe. This study surveyed the independent living residents of three CCRCs in the Midwestern states. Respondents placed great importance on taste and flavor of food which has the highest percentage of utility range ($28.28\%$) and the second greatest on appearance of the server ($23.46\%$) . The important attributes were ultimately used to predict the most preferred choice of food-service for residents. Knowledge of the importance of the attributes would enable the foodservice managers in CCRCs to manipulate those attributes to enhance the residents' perceptions of quality and identify strategies for continuous improvement.

  • In order to promote foodservice for the elderly, foodservice managers in Continuing Care Retirement Communities (CCRCs) must identify the main factors to enhance the satisfaction and behavioral intentions with food service. The purpose of this study was to investigate the relationships between relationship quality (consisting of trust, commitment, and satisfaction) and communication in the formation of elderly's behavioral intentions with food services at CCRCs. A survey was administered to residents in two CCRCs and a total of 327 residents participated. A tested structural equation model exhibited good model fit and explanatory power of the study construct. Satisfaction directly influenced word-of-mouth and service quality has an influence on commitment. Commitment was a significant determinant of behavioral intentions to eat more often in the dining room. Also, communication showed positive association with trust. The results provided strong evidence for the importance of satisfaction and communication as a consequence of relationship marketing efforts. Suggestions for future research to better understand the elderly' behavioral intention judgments were given.

  • The major trend in the antioxidant market is the growing consumer demand for natural antioxidants. Tea, one of the most widely consumed beverages in the world, is an easy way to obtain antioxidant components from a natural source. Our objective was to develop burdock root tea (BRT) with potent antioxidant activity and good color quality. In order to obtain maximum antioxidant activity and quality, the effect of roasting was determined. The antioxidant capacities and total phenolic contents of BRT increased as roasting increased. The color of BRT became darker with increased roasting, extraction time, and amount of burdock roots. Color of BRT was also positively correlated with total antioxidant capacity. Roasting significantly enhanced the total antioxidant activities and color quality of BRT. These results suggest that roasting BRT increases beneficial antioxidant components from burdock roots.

  • We manufactured the sausages replaced part (8%) of the pork fat (20.8%) with pepper seed powder (1%) and pepper seed oil (7%). The treatment of pepper seed did not affect pH and microbial quality, but decreased TBARS and VBN of sausages. Although the addition of pepper seed hardly changed textural properties of sausages except for increasing cohesiveness, it enhanced sensory characteristics such as taste, appearance, and overall acceptability. As expected, significant reductions were observed in the content of calorie, total fat, saturated fat, and sodium by replacing pork fat with pepper seed oil and pepper seed powder in sausages. Therefore, pepper seed is good enough to improve the sensory and nutritional quality of sausages.

  • This study was conducted to evaluate the quality characteristics and antioxidant activities of salad dressing prepared with acaiberry powder (0, 1, 3, and 5%). The pH and titratable acidity increased as the acaiberry powder increased. The sugar content showed no significant differences between samples. The viscosity was lowest in the controls and increased with increasing amounts of the acaiberry powder. The lightness and yellowness values decreased, while the redness values increased with increasing amounts of acaiberry powder. The total polyphenol content ranged from 10.26-45.19 mg GAE/100 g, increasing with increased acaiberry powder levels. The antioxidant activities measured via DPPH radical scavenging activity, reducing power and FRAP also increased with increasing acaiberry powder concentrations. Finally, a consumer acceptance test revealed that up to 3% acaiberry powder could be added to salad dressing to provide high antioxidant activity without sacrificing sensory quality.

  • This study aimed to determine microbiological quality on vegetable salad used dressing added with Prunus mume extracts. For this study, Dressing were blended with Prunus mume extracts to different concentrations of 0, 10, and 20%. Microbiological effects of vegetable salad used dressing added with Prunus mume extracts were assessed during production process by measuring process time, temperature, pH and Aw and determining total plate counts and coliforms. Effects of vegetable salad used dressing added with Prunus mume extracts on total plate counts and coliforms were observed during holding at 3, $25{\pm}1^{\circ}C$ for 12 hours. Dressing added with Prunus mume extracts improved the microbiological quality and showed antibacterial properties when they are added to vegetable salad.
