Assessment of heavy metals, minerals, alcohol, and fusel oil content of selected fermented plant beverages of Thailand

Abstract

© All Rights Reserved. Fermented plant beverages (FPB) are produced from cereals, fruits, vegetables and other plant sources. This study aimed to assess the heavy metals, minerals, alcohol, and fusel oil content of seventy FPBs sampled from several parts of Thailand. The results indicated that tested FPBs products were harmless for consumption except some of the products that are made from Morinda citrifolia Linn. The iron content of few products was found higher owing to the use of underground water for the production, which can be nullified by controlled consumption of FPBs. About 21 products are not suitable for consumption as per Thai community product standards (TCPS). All the samples were scored based on Australia New Zealand Food Authority standards (ANZFA), TCPS and Thai industrial standards-2089. The outcome of current study has revealed the importance of selection of raw materials for FPBs and also determined the quality of the selected FPB in Thailand.
