The role of moisture evaporation in the taste attributes of dry- and wet-aged beef was determined in this study. A total of 30 striploins (longissimus lumborum) were dry or wet aged for 28 days and analyzed for moisture content, taste-active compounds [free amino acids (FAAs), inosine 5'-monophophate (IMP), and reducing sugars], and taste attributes by an electronic tongue. After the completion of aging process, higher amounts of FAAs and reducing sugars were found in dry-aged beef (P < .05) in negative correlations with moisture content (r = -0.9 and - 0.9, respectively), which were not detected in wet-aged beef. However, the different taste attributes of dry- and wet-aged beef were observed by the electronic tongue from day 14, whereas their moisture content was significantly different only at day 28. Consequently, although the moisture evaporation during dry aging process contributed to the increased flavor of dry-aged beef, there are other factors affecting flavor development including microbial activity on the surface crust.

Background: Subcritical water (SW) is regarded as an effective conversion technology for lignocellulosic biomass. The effect of SW on ginseng are limited to evaluate the ginsenoside composition of red ginseng, and there is little information on the effects of SW on fresh ginseng.
Methods: The general characteristics of ginseng extracts (GE) prepared with SW were evaluated in terms of brix, reducing sugar and residual solid content, and compositions of GE was estimated using chromatography.

In recent years, there has been a surge in the production of kombucha-a functional beverage obtained via microbial fermentation of tea. However, fresh, unpasteurized kombucha is sensitive to quality deterioration as a result of, among other factors, oxidation. The addition of hops seems to be promising, due to their antioxidative properties, which may improve the stability of kombucha.

To study the characteristics of bread by incorporating nutrient-rich quinoa flour as a new source for product development. Wheat flour was replaced by fractionated quinoa flour in different variations from 0%QF to 20%QF: 0%, 5%, 10%, 15%, and 20% WQF blends, respectively. Physicochemical studies resulted in higher protein and fiber content for the higher blend.

The aim of the research was to determine the relationship between the perception of organic food characteristics and the demographic and social profile of consumers on the Polish market. The research focused on the general characteristics and features of plant and animal products offered on the organic food market compared to conventional food. The study was conducted on a sample of 1020 respondents from different regions of Poland using structural equation modelling, which allowed for the assessment of regression and covariance relationships between variables.
