Summary: Pangasius farming in Bangladesh has rapidly grown, but the industry faces low quality issues. This study examines whether domestic consumers are willing to pay more for higher quality pangasius. Results show that odor is the most influential attribute, with consumers willing to pay 7% less for bad-smelling pangasius. Other quality attributes, such as fish size, form, color, appearance, and abdomen, also impact purchase decisions. Consumer preferences for quality attributes vary based on individual demographics.

Summary: This study examines the impact of sustainable labeling on the price premium of agricultural products using rice on e-commerce platforms as an example. The results show a significant price premium for rice with sustainable labeling, with higher premiums for rice labeled as organic compared to green food. Factors such as e-commerce platforms, rice varieties, packaging, and importation also affect the price premium of rice.

Summary: This study investigates the relationship between product quality and price setting for CPUs. It finds that market fundamentals play a crucial role in explaining price stickiness and dispersion, and that calculations of price inflation need to consider both CPU quality and market fundamentals to ensure accurate pricing. Failure to do so may lead to an understatement of CPU price deflation.

Summary: This study examines the impact of metro and bus accessibility on housing prices in Beijing under a polycentric scenario, revealing that residential properties with more metro and bus accessibility tend to have higher prices. Additionally, metro stations have a more significant effect on housing prices, with higher metro premiums in the eastern part of polycentric Beijing.

Summary: An untargeted GC-MS method combined with sensory analysis was used to study the effects of different extraction methods on specialty graded Kenyan Arabica coffee. The results showed that different filter materials and shapes used for extraction led to differences in the composition of volatile compounds in the coffee. Samples extracted with paper filters had higher percentages of caramel- and flowery-related compounds, while samples extracted with metal filters had more fruity and roasted coffee flavors. Sensory evaluation revealed that French Press coffee received the lowest scores in all parameters except acidity.

Summary: The determination of sensory attributes of coffee samples through trained cupping tasters is important for coffee quality control, but may be distorted due to different interpretations of quality from tasters' perspectives. Hydrogen nuclear magnetic resonance (1H NMR) can predict sensory attributes using chemometric methods. Variable selection by Ordered predictors selection (OPS) improves the prediction of regression models. In this study, OPS-PLS model was the best strategy to predict aftertaste, balance, and fragrance, while OPS-SVR predominated in predicting acidity, body, and flavor.

Summary: Pulses are widely recognized for their high nutritional value, but in some European countries, consumption remains below recommended levels and production is unprofitable, leading to a reliance on imports. Pulses are suited for local food characteristics, and origin declarations on labels can have a positive impact on market prices.

Summary: This study examines the Scotch whisky geographical appellations and finds evidence of a collective reputation effect, even after controlling for individual reputation and bottle characteristics. The findings suggest that appellations can benefit from a reputation premium, without providing helpful quality signals for consumers.

Summary: Coffee processing contributes significantly to food and product waste. Utilizing coffee co-products can address environmental issues, nutritionally unbalanced foods, population growth, and food-related diseases. This research examined the quality and sensory parameters of cascara (coffee husks) and silverskin from different botanical origins, revealing their potential as valuable sources of TAC, fiber, and other beneficial compounds. The sensory evaluation, however, indicated that none of the samples met the acceptable index value of 70%.

Summary: This study investigates the potential and limits of a data-driven approach to describe the sensory quality of coffee using complementary analytical techniques. The analysis of coffee flavor chemical data from 155 samples highlights the variable influence that the nonvolatile fraction has on predicting flavor attributes. The data fusion emphasized the aroma contribution to driving sensory perceptions, while further investigation is needed to verify the potential of odor-taste integration.
