A comprehensive analysis of the aroma components of Italia grapes, a muscat-flavor grapes grown in Tianjin, was conducted using headspace solid phase micro-extraction（HS-SPME）, gas chromatography-mass spectrometry（GC-MS）, along with methods such as internal standard-standard curve quantification, odor activity value analysis and aroma profile analysis. The results showed that a total of 43 aroma components with alcohols, aldehydes, terpenes, and esters being the major components. The main compounds identified included 1-hexanol, trans-2-hexen-1-al, trans-2-hexen-1-ol, linalool, ethyl acetate, and hexanal. Odor activity value results showed that aroma of grape Italia was mainly contributed by 12 kinds of active aroma components, including linalool, hexanal,trans-2-hexen-1-al, 1-octen-3-ol, phenylacetaldehyde, ethyl hexanoate, trans-2-hexen-1-ol, heptanal, citronellol, ethyl butyrate, 1-hexanol and geraniol（OAV from high to low）.
