Abstract

The purpose of this research was to determine the effect of the concentration of maltodextrin and tween 80 on the characteristics of the gumitir flower instant drink powder and to proper concentration of maltodextrin and tween 80 to get the gumitir flower instant drink powder with the best characteristics by foam mat drying method. The research used two factor Randomized Block Design. First factor was concentration of maltodextrin that consisting of 3 levels (10%, 15% and 20%) and second factor was concentration of Tween 80 that consisting of 3 levels (0.3%, 0.5% and 0.7%) so there were 9 treatment combinations. The repetition of each treatment combination was carried out 2 times, in order there were 18 experimental units. The data were analyzed statistically usingthe variance test and if the treatment had a significant effect to observed variables, it was continued with Duncan's Multiple Range Test. The result showed that interaction of the concentration of maltodextrin and tween 80 had a significant effect (P<0,05) on moisture content, ash content, total dissolved solids, solubility, total phenol, total carotene, antioxidant activity, hedonic of color, scoring of aroma and scoring of taste. The concentration of 10% maltodextrin and 0.7% tween 80 was the best treatment to produce gumitir flower instant drink powder with the moisture content 3.94%, ash content 1.23%, total dissolved solids 15.2oBrix, solubility 92.18%, total phenol 93.29 mg GAE/g powder, total carotene 19.2 mg/g powder, antioxidant activity of powder 78.56% with IC50 valued 1195.72 ppm, sensory assessment of the aroma was preferred with characteristic aroma of gumitir flowers, the taste was preferred with characteristic taste of gumitir flower, the color was preferred and the overall acceptance was preferred.

Abstract

Cassava leaf has bioactive components, such as flavonoids and chlorophyll pigments, but the information on cassava leaf extract is still limited and needs development on the using extraction method of microwave. The type of solvent is an important factor in the success of extracting the material. This research was conducted to determine the effect of the solvent using Microwave Assisted Extraction (MAE) method on the characteristics of cassava leaf extract (Manihot utilissima Pohl.) and to find the right type of the solvent using Microwave Assisted Extraction (MAE) to produce the best cassava leaf extract. The research design used was a Completely Randomized Design with a solvent type treatment consisting of five types of solvents, namely aquades, ethanol 90%, acetone 90%, methanol 90%, and ethyl acetate 90%. The treatment was repeated three times to obtain 15 experimental units. The data obtained were analyzed by the analysis of variance and if the treatment had a significant effect to variable observed, it was continued with Duncan’s Multiple Range Test. The parameters observed in this study were yield, total chlorophyll content, total flavonoids content, antioxidant activity, IC50, and L*, a*, b* values. The result showed that the type of solvent had a very significant effect (P<0,01) on yield, total chlorophyll content, total flavonoids, antioxidant activity, IC50, and L*, a*, b* values. The best treatment was found in ethanol 90% which produced a yield 19.84%, total flavonoids 74.90 mg QE/g, total chlorophyll 9.98 mg/g, antioxidant activity 83.67%, and L*: 44.83, a*: -9.97, b*: 20.27.

“Kolang-kaling” is generally added with food coloring to make it look more attractive, one source of natural color that is safe for consumed comes from sappan wood. This study aimed to determine the effect of temperature and storage time on color stability and characteristics of “kolang-kaling” with the addition of extract sappan wood and to get the exact temperature and storage time to the maintenance color stability and the best characteristics of “kolang-kaling” with the addition of extract sappan wood. The experimental design used was a factorial randomized block design (RBD) with 2 factors. The first factor was temperature which consists of 3 levels (refrigerator temperature, room temperature and 400C). The second factor was the time of storage which consists of 4 levels (1 days, 3 days, 5 days, and 7 days). The treatment was repeated 2 times in order to obtain 24 experimental units. The data obtained were analyzed using analysis of variance and if the treatment had an significant effect on the test parameters, then continued with the Duncan Multiple Range Test (DMRT). The results showed that interaction of the temperature and storage time had a very significant effect on color intensity, total anthocyanin, hedonic of color, hedonic of aroma, hedonic of texture, overall acceptance, scoring of color, scoring of aroma, and scoring of texture. Refrigerator temperature and storage for 1 days was the best treatment to maintain the colorant stability and characteristic of the “kolang-kaling” extract sappan wood with the color intensity of 0.70, value L* 23.8, a* 47.4, b* 57.8, total anthocyanin 10.79 mg/100g, pH 6.0, antioxidant activity 77,0%, also sensory evaluation color was red and liked, aroma was typical of “kolang-kaling” and liked, texture was slightly chewy and liked, and overall acceptance was liked.

Abstract

The cassava leaves (Manihot esculenta Crantz) is a type of green vegetable that contains nutrients and contains chlorophyll and flavonoids which are good for consumption, but the utilization of cassava leaves is still minimal and food diversification is needed. This study aimed to determine the concentration effect of CMC toward characteristics of cassava leaf powder with foam mat drying method and determine the appropriate concentration of CMC to produce cassava leaf powder with the best characteristics by foam mat drying method. The research used a completely randomized design (CRD) with CMC concentration treatment consisting of seven levels (0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, and 3.0%). The treatment was repeated twice, so that 14 experimental units were obtained. The data obtained were analyzed of variance and if the treatment had an effect on the observed parameters, it was continued with Duncan's Multiple Range Test (DMRT). The results showed that the concentration of CMC had a significant effect (P<0.05) on the observed parameters, namely water content, ash content, yield, total chlorophyll, flavonoid content, solubility, soluble time, and L*, a*, b* values. The best treatment was obtained at 3.0% CMC concentration with the following characteristics: water content of 1.53%, ash content of 5.77%, yield of 11.09%, total chlorophyll of 9.29 mg/g, flavonoid content of 11.39 mg QE/g, solubility of 82.82%, dissolving time of 28.85 s, L* value of 13.45, a* value of -36.15, and b* value of 10.55.
