Vinegar, an integral component of Filipino cuisine for ages, has become susceptible to falsification with the incorporation of non-biogenic acetic acid, owing to its popularity. A fresh technique employing radiocarbon analysis has been devised to identify the presence of non-biogenic acetic acid ...
Possible adulteration of canned products containing spirit vinegar pickle by adding synthetic acetic acid is a significant problem of the food industry. Isotope analyses, which determine botanical origin of acetic acid and also can detect synthetic acid, were applied to detect undeclared addition of ...
are limited on ISS. This is a consequence of the mass and volume limitations that are associated with any human spaceflight mission and prioritization of needs based on perceived risk. The decision on what to include in the CHP systems of future missions becomes more challenging as those mass a...
A sensitive, new color reaction for the detection of citric and tartaric acids in vinegar has been developed. Acetic anhydride in the presence of trimethylamine has been used as the reagent. Traces of citric (2 μg) and tartaric acid (5 μg) can be detected in concentrated acetic and ...
One interesting screening method is the application of 3% to 5% acetic acid, which has been used for cervical cancer screening. The primary objective of this study was to assess the sensitivity, specificity, and accuracy of using vinegar (5% acetic acid) for the examination of oral cancer. ...
Besides, the concentration of acetic acid was calibrated and a mixture of the investigated acids was also studied. Finally, the new method's capability to detect acetic acid in five different brands of edible white vinegar was evaluated. The experimental results show that negative photoionization ...
The detection method is simple and convenient for actual detection of alcohol of solid fermentation substrate of vinegar, detection results are accurate, lower limit of detection reaches 0.02%, and conversion of alcohol and acetic acid in fermentation process of solid acetic acid can be reflected ...

The method comprises the following steps of discriminating vinegar rhizome cyperi and dried orange peel by a thin layer chromatography; and determining three part contents of paeoniflorin by a high-efficiency liquid phase method, wherein a sample solution is prepared by the following steps of: ...
the sensor showed good selectivity towards Hg2+ion with respect to common metal cations. The sensor was successfully applied for determination of Hg2+ion in some real samples, including hair, urine and well water samples. The results were in good correlation with the data obtained using cold vapo...
