Cocoa bean is a rich source of polyphenols, which are the largest group secondary metabolite with natural antioxidant property. Polyphenols from cocoabeans was reported to possess health benefits. Fermentation, one step in cocoa processing is needed to improve the quality of cocoa in which the concentration of cocoa bean polyphenols might decrease significantly through oxidation and exudation. Cocoa polyphenols content among different cocoa clones mightalso vary. The aims of this study were to determine total polyphenols, total flavanoid, epicatechin, and catechin content in several cocoa clones, those wereSulawesi 1, Sulawesi 2, ICCRI 03, and KW 617. Until now, characterization of polyphenols from those clones has not been reported. The effect of five daysfermentation to those parameters was also studied. The results of the study showed that fermentation and type of clones significantly affected total of polyphenols, total of flavanoids, epicatechin, and catechin content of the cocoa, there is also an interaction between fermentation and type of clones. Unfermented of Sulawesi 1 had the highest total polyphenols of 96.94±5.83 mg/g, total flavanoids of 90.92±1.89 mg/g, epicatechin of 52.50±0.46 mg/g, and catechin of 1.99±0.02 mg/g content compared to other clones. Among five days fermented cocoa beans, Sulawesi 2 showed the highest total polyphenols and total flavanoids content, while ICCRI 03 had the highest epicatechin and catechin content than other clones. Thus, in can be concluded that although fermentation is required to improve the flavor quality of cocoa, it significantly reduced the content of bioactive compounds. This effect varied amongdifferent cocoa clones.

A study was carried out to characterize the cocoa lipase from cocoa beans (Theobroma cacao, L.) of clone PBC 159. The optimum temperature of cocoa lipase was 30-40 °C and the pH optimum was 7.0-8.0. The moleculer weight of the lipase enzyme was in between 45-66 kDa. The results indicate that Km value for cocoa bean lipase was 2.63 mM, when trimyristin was used as a substrate. The incubation of cocoa bean lipase with triolein and tributyrin (as substrate) yielded Km of 11.24 and 35.71 mM, respectively. The Vmax value obtained from the incubation of the lipase with a wide range of substrates, including tributyrin, trimyristin and triolein, are expressed as µmole acid/min/mg protein for cocoa lipase. Vmax values decreased with the increase in the triacylglycerol chain-length, with Vmax values of 27.78, 13.16 and 11.63 µmole acid/min/mg protein when incubated with tributyrin, trimyristin and triolein, respectively. Inhibition of lipase occurred in the presence of diisopropyl flourophosphate, N-bromosuccinimide and 5,5-dithiobis-(-2-nitrobenzoic acid).   Keywords: characterization, lipase, cocoa beans

Study of Assorted Fermentation Methods Conducted by Local Farmers on the Quality of VCocoa Beans (Theobroma Cacao L.). Various fermentation methods have been done by local farmers, however there has been no report on the quality of cocoa beans from those methods. This study aims were to identify various ways of cocoa beans fermentation conducted by local farmers; to compare between quality of fermented beans produced by local farmers and suggested quality of fermented beans; and o obtain a simple fermentation method which resulted in good quality beans and suitable practice for local farmers. The research wasconducted in Tabanan Regency, Province of Bali through field survey with observation and interview method, and supported with literature study. According to field observation and analysis of fermented cocoa beans taken from the local farmers, it can be concluded that most of local farmers did not fermented their kakao seeds. Thus, the fermentation done by utilizing a plastic sack, a bamboo basket or a wooden box lined and covered with banana leaves. The research also found that implementing similar fermentation methods to the seed did not always resulting similar quality of cocoa beans. Finally, the simplest method for local farmers to ferment the cocoa seed was the fermentation by utilizing basket lined and covered with banana leaves with at least 90kg wet beans.

Cocoa plant generally is classified as cross pollinated plant and self-incompatible plant, then there is indication the presence of pollen influence on cocoa bean quality. This study was aimed to determine the effect of pollen sources (xenia) on the colour and size characters of fresh cocoa beans (Theobroma cacao L.). This study was done on two stages. The first stage, a treatment of hand pollination of cocoa clones of DR 1, DR 2, DRC 16, KW 264 and ICCRI 03 was applied in this study. There were five treatments of hand pollination: DR 2 x DR 1, DRC 16 x DR 1, DRC 16 X KW 264, DR 1 x DR 2 and ICCRI 03 x DRC 16. Each treatment was repeated four times. Colour parameters of fresh cocoa beans were observed. The second stage consisted of nine hand pollination combinations: TSH 858 x Sulawesi 1, TSH 858 x ICCRI 03, TSH 858 x KW 264, TSH 858 x KW 570, TSH 858 x Sca 6, Sulawesi 1 x TSH 858, Sulawesi 1 x Sca 6, Sulawesi 1 x KW 570 and KW 516 x Sca 6. Each treatment was repeated three times. Size parameters of fresh cocoa pod and beans were observed. The result showed that hybridization using pollen source from bulk cocoa and DR 1 contributed dark colour to fineflavored cocoa. This colour contribution was showed by the increase in the dark fresh percentage of cocoa beans. On the other hand, hybridization using pollen source from fine-flavored cocoa contributed white and pale colour to bulk cocoa. This light colour contribution was showed by the decrease in the percentage of the dark fresh beans. Xenia effect occured on pod weight, pod length, pod girth, bean weight with pulp per pod and bean weight without pulp per pod which was shown by the hybridization with TSH 858 as female parent and weight bean without pulp per pod shown by the hybridization with THS 858 and Sulawesi 1 as female parent. Key word: Xenia, fresh beans colour, fresh beans size, Theobroma cacao L.

One of the productions of the agricultural industry that has a fairly high foreign exchange value for our country is cocoa, but our cocoa production is still of low quality. To get good quality cocoa, good processing must be done. Fermentation of cocoa beans is one way to improve the quality of cocoa so that it can be sold in national and international markets. The purpose of this activity is to help cocoa farmers, especially in Southeast Aceh district, in improving the quality of cocoa production, so that the cocoa products of Southeast Aceh farmers can compete in trade both locally and abroad. The implementation of this activity is carried out through training to improve the quality of cocoa. There are several activities, namely: Sorting Cocoa, peeling cocoa pods, fermenting cocoa pods for 5 days and the last step is drying until the moisture content of cocoa pods reaches 7%. The result of this activity is to increase the knowledge of cocoa farmers in Southeast Aceh Regency in order to improve the quality of cocoa beans, so that cocoa sales can be accepted and compete in the market.
