Highland Barley Replaces Sorghum as Raw Material to Make Shanxi Aged Vinegar

Highland barley (HB, Hordeum vulgare L. var. nudum Hook. f.), also known as naked or hulless barley, is a kind of cereal crop growing at high altitudes (4200–4500 m) around the world. In this study, HB vinegar (HBV) was prepared, using Tibetan main raw material, according to process Shanxi aged (SAV), famous in China, which sorghum usually used material. The related compounds, such alcohol and acetic acid, acid fermentation processes were monitored analyzed, respectively. flavor components vinegars analyzed by headspace solid-phase microextraction, combined with gas chromatography-mass spectrometry, compared (SV), made, based on SAV process. results revealed that stage, content mash higher than (p < 0.05), stages HBV SV, total contents 6.23 5.81 (g·100 mL−1 p After aging one half years, non-volatile volatile ester compounds those SV. Therefore, can replace material for making SAV. Based literature search, comparison analysis SV not studied before.
