Evolution of fatty alcohols in olive oils produced in Calabria (Southern Italy) during fruit ripening
1Università degli Studi Mediterranea di Reggio Calabria.
Abstract:
A study was conducted on olive oils extracted from olives collected in South West Calabria (Southern Italy) over three harvest years 2010-2011-2012. Three autochthonous cultivars were considered: Cassanese, Ottobratica and Sinopolese and seven allochtonous cultivars: Coratina, Itrana, Leccino, Nocellara Messinese, Nociara, Pendolino and Picholine. Thin Layer Chromatography - Gas Chromatograph (TLC-GC) technique permitted the separation and analysis of the fatty alcohol compounds. A general decline in fatty alcohol content was found during the three months of sampling, most evident in hexacosanol. Pendolino showed the greatest decline. A less evident decrease was measured in the odd chained fatty alcohols, mainly in heptacosanol. Both harvest date and cultivar significantly influenced the fatty alcohol content. This is the first report about the fatty alcohol variation during ripening in olive oil produced in South West Calabria (Southern Italy).

The process of oxidation in a chemical reaction is observed in any of the three forms:
01:57Preparation of Diols and Pinacol Rearrangement
The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.
02:23Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat...
02:15Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
