Understanding the volatile flavor compounds present in commercial beverages is crucial for the food and beverage industries as these compounds significantly influence product perception and consumer acceptability. This paper aims to comprehensively analyze the composition of volatile organic compounds in various commercial beverages using targeted gas chromatographic–mass spectrometry (GC/MS) approaches. The study employs a screening method based on the Headspace-GC/MS technique to efficiently extract and identify volatile organic compounds found in commercial beverages. This methodology provides a rapid and reliable system for assessing the volatile profile of these beverages. The analysis reveals the presence of a total of 40 volatile organic compounds, including esters, terpenes/terpenoids, alkenes, aldehydes, aromatic hydrocarbons, and alcohols. Medium-chain esters were found to dominate the volatile profile of the beverages, suggesting a significant contribution to their fragrance and taste. This study offers valuable insights into the volatile profile of commercial beverages, creating awareness among consumers about the flavor components present in these products. By understanding the volatile composition, consumers can make informed choices regarding their beverage consumption. The comprehensive analysis provided by this research serves as a foundation for further studies related to flavor characterization and optimization in commercial beverages. [ABSTRACT FROM AUTHOR]

The current social dynamism is a complex factor that contributes to the manifestation of some psychoemotional states that cause the appearance of both functional and neuropsychic disorders. In this context, in the present paper, we review the implications of psychosomatic diseases in regulating the psychoemotional status of patients based on the specialized literature in the field. [ABSTRACT FROM AUTHOR]

The number of patients with psychosomatic diseases is constantly rising, as stressors have an increasing impact in the evolution of their health. Psychosomatic disorders reflect the causal relationship between stressors and physical illness, simultaneously affecting the appropriate functioning of the body and the patient’s cognitive abilities. In this context, this paper analyses the psycho-emotional status of patients with psychosomatic diseases based on a review of recent literature. [ABSTRACT FROM AUTHOR]

In this paper a special laboratory method which may lead to establish the existence time of ore lumps like ore pieces grinding in industrial autogenous mills as a function of their constructive and working characteristics is reviewed. The ores grind ability and this parameter, established in this way will constitute the main elements in the selection of diameter and working regime of the primary autogenous mill in order to obtain the maximum efficiency of respective ore comminution. To reverse, when a certain mill type is imposed, it is possible to establish the feed particle size and the product particle size in order to obtain efficiency in primary autogenous grinding.

This paper presents the research regarding the influence of ash on the filterability of sterile slurry from coal processing. For this there were made some fileterability tests using 1%, 3%, respectively 5% of ash content. After calculating the compression coefficient the best filtering installation was concluded to be press filters. [ABSTRACT FROM AUTHOR]

The success of separation of combustible matter from mineral matter using flotation is primarily dependent upon differences in the surface activity of species. The efficiency of the process is determined by the levels of certain operating variables of separation technique, reagent system being the most important lever in process management. In the case of coal with poor natural floatability, reagent system diversity represents an important proceeding for efficiency increasing. [ABSTRACT FROM AUTHOR]
