Merlot under Mediterranean climate》. The research results were published in《European Food Research and Technology》 in 2022.Recommanded Product: 124-06-1 The article conveys some information:
Merlot is one of the most cultivated cultivars in the world since it easily adapts to different climatic conditions. Leaf removal (LR) is commonly used for red berry varieties but in cold wine-growing areas and nothing has been reported on the effects of LR on Merlot cultivated under Mediterranean climate. The aim of the research is to evaluate the influence of this technique on grape and wine quality as well as wine aroma potential of Merlot cultivated in Sicily. Vines were subjected to LR for two consecutive years, and productivity and chem. parameters were monitored in grapes, whereas chem. composition and volatile aroma compounds, analyzed by gas chromatog. mass spectrometry, were monitored in wines. LR pos. influenced the plant yield, increased the sugar content and decreased the acidity in grapes at harvest. The wines of the defoliated treatment showed a higher content of total polyphenols and anthocyanins, higher color intensity, and lower color hue. Merlot wines obtained under Mediterranean climate were characterized by a high amount of esters and varietal aromas and the content of most of volatiles were even increased by the LR with pos. effects on the aroma potential of Merlot wines. The vintage affected almost all the studied parameters with the warmer and dryer vintage enhancing the LR effects on grapes and wines. This is of great interest in the light of the climate changes towards the global warming and the increasing aridity of the Mediterranean area.Ethyl tetradecanoate (cas: 124-06-1) were involved in the experimental procedure.
Ethyl tetradecanoate(cas: 124-06-1) is a natural product found in Psidium guajava, Litchi chinensis, and other organisms.Recommanded Product: 124-06-1Ethyl myristate is a long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of myristic acid with the hydroxy group of ethanol.
