Abstract

Aims: To describe selected regulatory standards and final product testing methods applied to assess the chemical composition of natural alkaline mineral water. Methods: This study summaried key chemical parameters of alkaline mineral water according to national and international standards for the quality management of natural mineral waters, and reviewed systematic analyses and primary studies in peer-reviewed international journals. The chemical indicators of the Vikoda natural alkaline mineral water, that had been mechanically filtered and sterilized by UV rays and bottled, were evaluated according to national and international standards.

Results: According to QCVN 6-1:2010/BYT issued by the Ministry of Health on June 2, 2010, regarding the “National technical regulation for natural mineral water and bottled drinking water,” and compared with periodic post-inspection test results from 2022 to 2025: All chemical test results were within the allowable safety range, no heavy metals such as lead were detected. Its naturally high pH of 8.5–9.5 was above the WHO average recommendation but still within Codex limits - a characteristic biological marker of natural alkaline water. The metasilicic acid content (80–155 mg/L) far exceeded the minimum recommendation (>10 mg/L). Bicarbonate and total dissolved solids (TDS) were within the ideal range.

Conclusion: National and international technical standards for natural mineral water have been presented and compared with the post-inspection results of the finished Vikoda natural mineral water. The post-inspection results are very important evidence for ensuring the quality of the finished natural mineral water after extraction and for developing alkaline mineral water products that meet national standards and satisfy Codex requirements.
