Effect of some factors post-harvest on the sensory quality of the Criollo cocoa porcelana (Theobroma cacao L.)

Abstract

Cocoa (Theobroma cocoa L.) has had a great importance in the agricultural development of the country since the time of the colony, due to the production of high quality cocoa (porcelana and chuao). To guarantee this quality it is important a good handling of the crop that includes a suitable practical postcrop (fermentation and dried). Therefore, the aim of this research is to evaluate the effect of some factors that influence on the fermentation of porcelain cacao such as: Type of fermentator (TF), removal frequency (FR), endurance of the ear (AM) and type of fermentator (TPF). The methodology consisted on a split plot arrangement design, where three factors were studied (TF, FR and AM), at two levels and the time of fermentation (TPF) at five. The evaluation was sensorial considering the following descriptor: acidity, smell, bitterness, astringency, floral, fruit and global evaluation. Fermented cacao on squared boxes had lower acidity than fermented in rectangle boxes. At the same time, a global evaluation was obtained in cacaos that fermented on squared boxes. In relation to the endurance, the best results of aromatic intensity and global evaluation, as well a lower acidity was obtained for endurance cero. The removal frequency done every 24 hours showed a lower bitterness and higher preference. The time of optimum fermentation was of 48 and 72 hours. These results allow recommending that porcelain cacao must be fermented on squared boxes, with a mass removal every 24 hours, with cero endurance and a time of fermentation that would not surpasses 72 hours.
