Description |
Organic acids are one of the major phytochemicals in vegetables and responsible for food taste and odor. Different organic acids are analyzed in fruits and cereals, but least in vegetables and spices. Organic acids has been analyzed because of their high importance in the formation of other phytochemical and increased antioxidant activity. The aim of the current research was to determine the oxalic, tartaric, quinic, malic, malonic, ascorbic, citric, fumaric, succinic, salicylic and benzoic acid content in fresh and pre-treated (with steam) vegetables and spices using high performance liquid chromatography (HPLC) method. Major organic acids in highest concentrations in spices and vegetables are quinic, malic, malonic and citric acids. Spices contain higher total organic acid content than vegetables. Using steaming as pre-treatment, some of the organic acids content significantly decreased. Obtained changes could be explained by the organic acid formation into more complex chemicals in food or metabolic process. For the future, these changes will be combined with individual phenolic compound changes in analyzed samples.
