Mangosteen vinegar from Garcinia mangostana: quality improvement and antioxidant properties

Mangosteen (Garcinia mangostana Linn.) fruit is rich in phenolic compounds which function as antioxidants and play a role in anti-inflammation, anti-hyperlipidemia, and anti-diabetic nephropathy. To investigate mangosteen vinegar (MV) by steaming under high pressure, explore the effects of fermentation, antioxidant activity, and sensory evaluation acceptable using the 9 -point Hedonic scale. Steamed mangosteen was processed to produce 3 types of mangosteen vinegar: mangosteen rind vinegar (MRV), mangosteen flesh vinegar (MFV), and mangosteen rind plus flesh vinegar (MRFV). All 3 kinds of mangosteen vinegar were obtaining >4% acetic acid and significantly higher total phenolic content (TPC), total flavonoid content (TFC), and free radical scavenging ABTS thorn and DPPH- antioxidant activity than apple cider vinegar (ACV) (p < 0. 05). The phenolic compounds analysis of mangosteen vinegar using HPLC were found Gallic acid, Catechin, Epicatechin, Vanillic acid, Trans-ferulic acid, Rutin, Gamma-mongostin, and Alpha-mangostin which showed almost higher than that found in ACV. Therefore, MVs produced from streamed mangosteen have higher antioxidants and were more acceptable using the 9-point Hedonic scale, a significantly higher statistical analysis of sensory evaluation than ACV, especially MFV. Taken together, steamed MVs should be further studied to prove the health benefits as a dietary supplement.

Automated summary

Mangosteen vinegar produced through steam distillation has higher antioxidant activity and contains abundant phenolic compounds. Compared to apple cider vinegar, mangosteen vinegar exhibited higher total phenolic content, total flavonoid content, and free radical scavenging activity. HPLC analysis revealed the presence of various phenolic compounds in mangosteen vinegar, which were found to be higher than those in apple cider vinegar. Mangosteen vinegar received higher acceptance in sensory evaluation.
