Profile of the diterpenes, lipid and protein content of different coffee cultivars of three consecutive harvests

  • Received: 13 April 2016 Accepted: 09 June 2016 Published: 25 January 2016
  • Some compounds found in coffee, such as cafestol and kahweol, have been linked to human health, whereas others, such as lipids and proteins, are associated with beverage quality. Several factors affect the concentration of these compounds in coffee. This study aimed to evaluate the profile of cafestol, kahweol, lipids and proteins in coffee cultivars of different genetic background grown in the same edapho-climatic conditions in three consecutive harvests. Cultivars derived from introgression of C. canephora genes via Timor Hybrid and Villa Sarchi presented high kahweol and low cafestol content that remained stable for three years. In the principal component analysis, cafestol, protein and lipid values contributed highly to the separation of the three harvests, whereas kahweol values separated cultivars among harvest years. There is no year effect on the diterpene profile among the cultivars. Thus, due to the profile and the stability of diterpenes at this location, and taking into consideration healthy issues related to coffee consumption, we can begin to recommend coffee cultivars with different diterpenes concentrations.
