Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

\nAn analytical method for determination of volatile organic compounds (VOCs) in Kazakhstan red wine was developed in this study. The volatile composition of red wine was determined by headspace SPME in combination with GC-MS. The DVB/CAR/PDMS fiber and the sample volume of 10 mL were chosen. The optimal conditions for HS-SPME were temperature of 30°C and extraction time of 60 s. Addition of 3 g NaCl and no pH adjusting were the most suitable parameters for extraction of VOCs from wine. The developed methodology enables to identify compounds referring to the following classes such as esters, alcohols, aldehydes, acids, ketones and naphthalenes and can be applied for forensic examination of Kazakhstan red wine.\n
