Abstract

The technology that is widely used in making snacks is extrusion. Most commercially available extruded products use corn grit as the main ingredient. Corn grits can be combined with high-starch ingredients such as sago. Sago has great potential to be developed considering that sago production in Indonesia is very high, but its use is still limited. Sago is usually only processed as traditional food, so further innovation is needed. Therefore, this research aims to examine the effect of sago composition (0%, 10%, 20%, 30%) and barrel temperature (120⁰C, 130⁰C, 140⁰C) on the characteristics of extrudates made from corn grit and sago starch. The extrusion process was carried out with a SYSLG-IV twin screw extruder. it was found that increasing the proportion of sago starch and barrel temperature causes an increase in the expansion ratio (3.21-3.81), WSI (2.78-11.49) and a decrease in water content (7.15-10.16), particle density (0.13-0.22), bulk density (0.07-0.11), WAI (5.94-6.6), and hardness (3.59-5.96). The best treatment based on TOPSIS analysis was the sample with a sago composition ratio of 30% and a temperature of 140⁰C

Abstract

Coffee is a kind of drink that comes from the processing and extraction of coffee beans. In the production of coffee powder, the flavor is the essential quality because flavor affects consumer preferences. To produce a coffee drink that has a distinctive flavour, that is by combining robusta coffee beans and black glutinous rice. The purpose of this study was to determine the best treatment combination of temperature and roasting time of robusta coffee beans and black glutinous rice on the quality of the coffee powder. The research design used RAK which was arranged in a factorial manner of two factors, namely roasting temperatures of 190°C, 200°C, 210°C, and roasting times of 10, 15, and 20 minutes, to obtain 9 treatment combinations, 3 replicates. The research data were analyzed statistically by the ANOVA test, followed by the BNJ test. While the hedonic quality test is analyzed using the Friedman method. The Effectiveness Index test does determination of the best treatment. The best quality of coffee powder is produced at a temperature and roasting time of 200°C 20 minutes, namely the yield of 8.40%, the water content of 1.39%, ash content of 3.80%, the caffeine content of 1.33%, total antioxidants 71.87%, organoleptic characteristics, namely flavor 3.73 (strong), acidity 3.40 (quite sour), body/mouthfeel 3.67 (thick) and color 3.53 (black).

Abstract

Rose petals is potential ingredient for making a herbal tea. This study was aimed to determine the effect of various drying methods on the physical and chemical properties of the dried rose. The methods tested were freeze drying (FD), cabinet drying (CD), and sunlight drying (SM). Several properties included final moisture content, bulk density, shrinkage ratio, rehydration ratio, color difference, flavonoid content, and surface microstructure of dried petals were examined. The results showed that the best-fit model for the prediction of CD was the firstorder kinetic model, with a drying rate constant of 0.0494% d.b./h. Meanwhile, both FD and SM required zero and first-order kinetics to effectively explain the drying characteristics. The drying constant rates for zero-order and first-order kinetics were 39.544 and 0.12% d.b./h for FD as well as 70.6 and 0.413%d.b./h for SM, respectively. The final moisture content of dried rose produced by FD, CD, and SM was 5, 12, and 10% wet basis (w.b), respectively. Based on the Indonesian National Standard, the maximum moisture content of packaged dried tea is 8% w.b. FD successfully reduced the shrinkage ratio to a range of 0.35 – 0.45. Freeze-dried rose petals at 40 °C temperature resulted in the highest flavonoid content of 5.65 g QE/100 g sample. In conclusion FD was the best drying method for producing herbal tea from rose petals. This method could be adopted as a new alternative for producing high-quality healthy herbal tea.
