Fermentation of Arabica Coffee Beans Using Ohmic Heating Technology in Producing Specialty Coffee
Get PDFCoffee is one of the most important agricultural commodities in global market. Therefore, the quality of coffee beans is certainly an important factor whichnotables in considering taste of coffee, especially on flavor profile. Coffee beans produced by farmers in Indonesia are generally “inferior quality of coffeeâ€, asmentioned unsorted or ungraded coffee/kopi asalan with defect score more than 225. It is caused by improper processing that is affecting coffee flavor becomestink and fermented. Improvement of post-harvest aspects are needed to upgrade coffee quality. This research examine a processing system using Ohmic-basedfermentation technology to produce specialty coffee. This research was conducted by setting the temperature (30, 35 and 40oC) and fermentation time (2, 6, 12, and 18 hours). The results showed that this treatments could gain cupping score anging from 81.81 to 85.25 with an average cupping score of 84.03. In this study,the application of 12 hours fermentation time and 35oC temperature generated the highest cupping score of 85.25. The best coffee flavor by applying 30oCtemperature was mouthfeel or body with cupping score of 7.81, whereas flavor, aroma and balance were the best characteristic coffee profile by applying 35oCtemperature on the fermentation process. On the other hand, fermentation temperature of 40oC generated high preference score of balance, that was 7.84. In term of fermentation time, the best characteristics of 2 hours and 12 hours fermentation were flavor and aroma, respectively. Enrekang Arabica coffee has 21 flavor profiles.

Good Agricultural Practices (GAP 1) Programme and Its Implications on Cocoa Yield of Participants in Ondo State, Nigeria
No full textThe continuous fall in the output of cocoa in Nigeria in the past years has been a great concern to the Nigerian Government. Cocoa which is the majorexport crop in Nigeria is experiencing drop in the foreign exchange earnings accruing to the Nigerian Government from its exportation. It is therefore necessary to restore the relevance of cocoa export to the forefront. This necessitated the Federal Government to embark on phase 1 of a programme called Good Agricultural Practices (GAP 1) in which selected cocoa farmers were trained on best sanitation practices that will improve cocoa production. This research determined the effects of farm sanitation training on cocoa output and also determined the relevance of farm sanitation training in cocoa production. Using random sampling procedure; one hundred and ten (110) respondents were selected from the 140 farmers trained on cocoa farm sanitation under the GAP 1 programme of Federal Ministry of Agriculture in partnership with Ondo State Agricultural Development Programme (ODSADP). A well-structured questionnaire was used to gather information from the farmers. Data were analysed using descriptive and inferential statistics such as Chi-square, Pearson Product Moment Correlation and paired T-test. The results revealed that majority (64.5%) of the farmers were male and married (67.3%). The average age of the respondents was 56 years, 18.2% had completed primary school education. The study revealed that cocoa farmers were trained on removal of black pods, cankers, mistletoes, chupons, termites and weeds. The findings also revealed that there was a significant relationship (x2 = 13.220, P = 0.040<0.05) between respondent’s marital status and level of use of farm sanitation training. There was also a significant difference between the cocoa farm output before and after farm sanitation training. There was an increase of cocoa output of the respondents by average of 41.28kg/ha. The use of farm sanitation training was responsible for 7% proportion of the increase in the output of the respondent’s farm. The results of the study further show that there was high level of contact betweenthe cocoa farmers in the study area and the extension agents. Major source of information to the respondents was extension agents of Ondo State ADP. Thefarmers practised the various farm sanitation techniques on which they were trained such as removal of canckers, removal of mistletoes, removal of chupons, hand weeding and picking of unwanted materials. The training variable with the highest impact on the output was removal of pods infected with black pod which brought about 0.290 units change in the output of the cocoa based on the coefficient
Chlorogenic Acid Isolation from Coffee as Affected by the Homogeneity of Cherry Maturity
Get PDFChlorogenic acid is a polyphenol compound which has an antioxidant properties. The objectives of this research are to understand and compare the characteristics of caffeine, chlorogenic acid, and polyphenolic content in Robusta coffee treated differently. These are necessary to find out effective postharvest methodfor chlorogenic acid extraction. There were two group of samples with the different treatment in process and post harvests. The coffee was treated differently during the sortation and classified into selected coffee of red cherry (fully mature cherry) and unselected coffee (partly mature cherry). The sortation was to maximize the chlorogenic acid content in green coffee bean sample from red cherry bean as the raw material. This research found that the contents of chlorogenic acid extract of green coffee bean from the selected red cherry was higher than the unselected. The HPLC analysis for chlorogenic acid contents of green coffeebean from the selected red cherry was 4.41%, it was higher than other samples tested

Growth Response of Seedlings of Four Robusta Coffee (Coffea canephora Pierre. Ex. A. Froehner) Clones to Drought Stress
Get PDFDrought is one of the limiting factors for the growth and yield of coffee plants. Drought due to long dry season has caused many losses for coffee plantations. This study aimed to evaluate the response of four Robusta coffee clones to drought stress at seedling stage and determine the best clone with high tolerance to drought. The study was conducted in Indonesian Coffee and Cocoa Reseach Institute (ICCRI) Jember, East Java in November 2018–Mei 2019. The experimental design used a Randomized Block Design (RCBD) with two factors. The first factor has consisted of five levels drought through providing volume watering based coefficient and evaporation value of free water surface (Eo), namely: 0.5 Eo; 1.0 Eo; 1.5 Eo; 2.0 Eo; 2.5 Eo (control). The second factor has consisted of four Robusta coffee clones, namely: BP 409 (drought tolerant clone); BP 308; BP 939 and BP 358 (vulnerable to drought stres). The result showed that reduction in the volume of watering from 2.5 Eo until 0.5 Eo causes drought, reduce coffee growth linearly. Clone BP 409 and BP 939 had better tolerance of drought stress compared with BP 308 and BP 358. The anatomical adaptation of leaves of BP 409 to drought stress was by thickening of wax layer and palisade tissue. BP 939 thickened its leaves due to drought stress as a mechanism of adaptation to such condition
