Italian scientists discover two new ingredients in wine, two isopropyl malicacids

Recently, a team at the University of Carmeno in Italy discovered two new molecules that make up wine: 3-isopropylmalate malic acid and 2-ipropylmaliatmalic acidThe major findings have been published in food chemistry, the world's leading academic journalProfessor Giovanni Caprioli and Massimo Ricciutelli, heads of theresearch team, said 3-isopropyl malic acid and 2-isopropyl malic acid are derivatives of malic acid and organic diazee acid and are decisive factors in wine aroma and flavorUsing high-precision mass spectrometry, the researchers tested the content of the two newly discovered substances in wine and found that they were high in wine, reaching a concentration of 30 mg/L in red wine and 20 mg/L in white winediscover and define new ingredients in both wines will open up a series of scientific studies of the wineNext, the researchers will delve into the structure of the two molecules, analyzing their effects on the age of the wine, its color, and the style characteristics of the grape varietynational standard for winewine GB15307-2006, the methanol content of each liter of wine must be less than 400 mg, if the methanol in the wine is too high, will be harmful to nerves and eyes, leading to blindnessSource:
