Abstract

Cocoa powder is one of the main products of the cocoa grinding process which is frequently used in confectionery industries. Today, the utilization of cocoa powder has been derivatized not only it can be used as food ingredient, but also expanding in its utilization in pharmaceutical. The utilization of cocoa powder mainly due to its advantageous and healthy polyphenol content which should be extracted from cocoa powder. Generally, this process will result in significant amounts of underutilized cocoa powder grounds. This research was carried out to evaluate the utilization of ultrasound-assisted extraction method to extract antioxidative compound from cocoa powder and to study the possibility of utilizing its grounds for its antioxidative compound by the use of papain solution system. The extraction study was carried out using different concentration of ethanol ranged from 53.79, 60, 75, 90 and 96.21% for 23.39, 30, 45, 60 and 66.21 min extraction time. The evaluation was carried out using the analysis of total phenolic content and DPPH radical scavenging activity. Further, freshly prepared papain was used in different concentration ranged from 2, 4 and 6% to incubate the cocoa grounds for 2, 3, and 4 hours. The obtained cocoa hydrolysate solution was then analyzed for its protein content and its antioxidant activity. The optimization study of the process was carried out using response surface methodology. This study shows that the use of 60% ethanol for 30 min extraction was optimum to extract the phenolic compound from cocoa powder. On the other hand, the use of papain revealed that the underutilized cocoa grounds could be potentially used as the source of protein and antioxidant.

Abstract

Consumer perspective of consuming coffee product has begun to shift not only for solely “pleasure” purpose, but also to consider its beneficial aspects. Red kidney bean (Phaseolus vulgaris L.) is a good source of fiber, protein and micronutrients to enhance the quality of beverages. This research was aimed to evaluate the effort to substitute milk with red bean powder in cinnamon herbal coffee and to study the enhancement of its nutrition content as well as the consumer perception and sensory properties. Red kidney bean powder was used to substitute milk powder and was blended with pre-mixed cinnamon coffee approximately 4%, 8%, 12%, 16% and 20% to obtain ready to drink mixtures. The coffee and control were then subjected to consumer perception to 25 panelists and sensory analysis by three trained-panelists and were also analyzed for its relation with nutrition content. The result showed that the substitution of milk with red kidney bean powder up to 8% could still be accepted by untrained panelist and its addition up to 20% still acceptable by trained-panelists. Addition of red bean powder could improve protein content up to 89.3% and 133.0% of soluble fiber content compared to the coffee that used full milk powder. This result showed that red kidney bean powder could be used to substitute milk powder in coffee beverages since it significantly improved the nutrition value and resulted in good sensory properties.

Abstract

Coffee spent ground is a primary by-product obtained during soluble coffee processing and potential to be utilized as a high value product due to its protein content. The quite popular effort to utilize protein-contained material is to process it to hydrolysate which also possess antioxidant activity. This research was aimed to study the possibility of protein and antioxidative compound from coffee spent ground by means of enzymatic hydrolysis using crude papain enzymes. Crude papain was used in different concentration ranged from 2, 4 and 6% to incubate the coffee spent grounds for 2, 3, and 4 hours and then analyzed for its protein content and its antioxidant activity, whereas response surface methodology was employed to study the tendency of the effect of incubation time and enzymes concentration towards hydrolysis results. The result showed that the use of crude papain was effective to liberate the protein and antioxidant compound the coffee spent ground with its optimum condition utilized 6% of enzyme and 2 hours incubation time. At mentioned condition, it could extract up to 67.38% of the protein of the coffee spent ground and its hydrolysate possessed relatively high antioxidant activity.
