Polyphenols in cocoa ( Theobroma cacao L . )
Polyphenols have gained much interest recently due to its antioxidant capacity and possible benefits to human health such as anti-carcinogenic, anti-atherogenic, anti-ulcer, antithrombotic, anti-inflammatory, immune modulating, anti-microbial, vasodilatory and analgesic effects. Cocoa (Theobroma cacao L.) is a rich source of polyphenols and reported having high antioxidant activity than teas an...
متن کاملKaryotype variation in cultivars and spontaneous cocoa mutants (Theobroma cacao L.).
Four mutant cocoa accessions with morphological changes and a cultivar sample were karyomorphologically characterized. Slides were prepared by enzymatic digestion of the root meristem and squashed in 45% acetic acid, followed by 2% Giemsa staining. The chromosome number of 2n = 20 was seen in all accessions. The karyotype formula for Cacau Comum and Cacau Rui was 2n = 20m. Submetacentric chromo...

متن کاملUse of a Proteolytic Enzyme in Cocoa (Theobroma cacao L.) Processing
Protein hydrolysis using an exogenous protease on cocoa nibs was performed to verify the formation of precursors and the effect on cocoa flavour. An experimental design was used to check the influence of temperature (30 to 70 C) and enzyme : substrate ratio [E/S] (97.5 to 1267.5 U g of protein). The % Degree of Hydrolysis (% DH) was affected mainly by [E/S] leading to a 4-fold increase (from 5 ...
متن کاملAssessment of the value of doubled haploids as progenitors in cocoa (Theobroma cacao L.) breeding.
In order to evaluate twelve doubled haploids (DHs) of Theobroma cacao L. used as parents, a trial was set up in Côte d'Ivoire. Several traits were observed, such as yield, vigour, yield/vigour ratios, resistance to the black pod disease caused by Phytophthora, percentage of flat beans and mean weight of 100 cocoa beans. Out of the three progenies derived from crosses between two DHs, two showed...
