Abstract:
Taking the ‘Vidal’ grape and its bud variant fruit as the test materials，and amino acid analyzer and fluorescence quantitative analysis were used，the dynamic content of phenylalanine，phenylethylamine，phenylacetaldehyde，and 2-phenylethanol in the ‘Vidal’ grape and its bud variant fruit were studied，as well as the dynamic relative expression of AADC enzyme，in order to clarify the synthesis changes the characteristic aroma of 2-phenylethanol in the excellent bud variant of the ‘Vidal’ grape，and the source were provided with raw materials for the production of excellent brewing varieties (series).The results showed that the content of phenylalanine，phenylacetamine，phenylacetaldehyde and 2-phenylethanol of the fruit was changed regularly in ‘Vidal’ grape and bud variant，and the content of phenylalanine，phenacetamine，phenylacetaldehyde and 2-phenylethanol in the ‘Vidal’ grape were higher than bud variant.The fluorescence quantification showed that AADC enzyme expression was positively correlated with 2-phenylethanol content in both ‘Vidal’ and bud variant.The bud variant of ‘Vidal’ was expected to provide an important variety (series) for the production of excellent wine in China.
