Abstract

Natural dyes can be used as an alternative to minimize the negative effects of using synthetic dyes. One type of natural dye that can be used is cassava leaves, because cassava leaves have a fairly high chlorophyll, namely 27.446 mg/g. The purpose of this study was to determine the effect temperature and time of drying to produce instant dye powder from cassava leaves. The research design used was factorial completely randomized design with drying temperature treatment consisting of 3 levels: (50 ?C, 60 ?C and 70 ?C) and drying time treatment with 3 levels: (4 hours, 5 hours and 6 hours). This study was repeated 2 times to produce 18 experimental units. The data were analyzed by analysis of variance, if the treatment had a significant effect, it was continued with Duncan's Multiple Range Test. The results showed that the interaction of temperature and drying time significantly affected the yield, moisture content, ash content, total chlorophyll, solubility, solubility time and brightness level (L*) of cassava leaf instant dye powder. The characteristics of the best cassava leaf instant dye powder were obtained at a drying temperature of 50 ?C and a drying time of 4 hours with a yield of 9.73%, water content 7.29%, ash content 0.75%, total chlorophyll 9.86 mg/g, solubility 42.96%, and color with criteria of brightness (L) 27.10, greenish (a*) - 33.80 and yellowish (b*) 9.00.

Abstract

Herbal tea is an efficacious herbal drink that is generally made from one or several ingredients made from dried leaves, seeds, wood, fruit, flowers, apart from the tea plant (Camellia sinensis). One of the plants that can be used as herbal tea is matoa leaves (Pometia pinnata). There are important stages in herbal tea processing that can affect the quality of herbal teas, namely drying which includes temperature and drying time. This study aimed to determine the effect of temperature and drying time on the characteristics of matoa leaf herbal tea and to obtain the right temperature and drying time that can produce matoa leaf herbal tea with the best characteristics. The experimental design used in this study was a factorial Complete Randomized Design (CRD) with 2 factors consisting of 3 levels each. The first factor is the drying time (W1 = 1 hour, W2 = 2 hours, W3 = 3 hours). The second factor of drying temperature (T1= 50oC, T2= 60oC, T3=70oC). The above treatments were repeated 2 times so that 18 experimental units were obtained. Analysis of variance was used to assess the data that were acquired and if the treatment had a noticeable effect, it was continued with the Duncan Multiple Range Test (DMRT). The results showed that the interaction of temperature and drying time had a significant effect on water content, extract content in water, total phenols, tannin content and antioxidant levels of herbal tea matoa leaves. Temperature and drying time had a significant effect on ash content, total flavonoids, taste (based on scoring and hedonic tests) and overall acceptance of herbal tea matoa leaves. The best treatment was obtained at drying with a temperature of 70oC and drying time of 3 hours with a characteristic moisture content of 5.10%, ash content of 6.29%, water extract content of 76.04%, total phenols content of 108.36 mgGAE/g, total flavonoids content of 9.52 mgQE/g, tannin content of 0.67 mgTAE/g, antioxidant content of 78.03%, neutral color, neutral aroma, dislike taste with bitter taste score, and neutral overall approval.

Abstract

Lemongrass essential oil microemulsions can be used as natural preservatives by enhancing their solubility stability and effectiveness. This study aims to determine the effect of the surfactant combination ratio (Tween 80, Span 80, and Tween 20) and lemongrass essential oil on the characteristics of lemongrass essential oil microemulsion, as well as to determine the optimal surfactant combination ratio (Tween 80, Span 80, and Tween 20) and lemongrass oil ratio that yields the most stable microemulsion characteristics for lemongrass oil. The study was conducted in two stages using a Completely Randomized Design, followed by an Honest Significant Differences follow-up test. The first stage involved two factors. The first factor was the ratio of the surfactant mixture (Tween 80: Span 80: Tween 20), denoted as S1 (2,5:97:0,5), S2 (2,5:96,8:0,7), S3 (2,5:96,5:1), S4 (2,5:96,3:1,2), and S5 (2,5:96:1,5). The second factor was the ratio of surfactant to citronella oil, represented by F1 (90:10), F2 (85:15), F3 (80:20), F4 (75:25), and F5 (70:30). The results indicated that the turbidity index value was influenced by the ratio of the surfactant mixture and lemongrass essential oil, along with their interactions, both before and after centrifugation, and heating. The conclusion drawn from this study is that the F2S3 treatment represents the optimal formula for producing lemongrass essential oil microemulsions. This formula exhibits characteristic turbidity index values before centrifugation (0,153%), after centrifugation (0,173%), and after heating (0,229%) with a droplet size of 29,2 nm and a zeta potential value of 0,1 mV. Additionally, the microemulsion remains stable during an 8-week storage period.

Abstract

Moringa leaves and tempeh contains high levels of glutamic acid, which has the potential to be developed as a flavor enhancer substitute for monosodium glutamate (MSG). This study aims to determine the sensory characteristics and the effect of the percentage of additions (1%, 2%, 3%, 4%, and 5%) of moringa and tempeh-based flavor enhancers on processed foods in the form of spinach clear soup. The design used in this study was a completely randomized design. The variables observed included the testing of sensory properties in the form of a threshold stimulation test, duo trio test, scoring test on taste parameters, and hedonic test on color, aroma, taste, and overall acceptance parameters. Data were analyzed by Analysis of Variance (ANOVA) and followed by Duncan's test. The results showed that flavor enhancers based on moringa leaves and tempeh had an absolute threshold of 0.17% and a difference threshold of 0.25%, and had a different level of umami flavor compared to MSG. The percentage of the addition of flavor enhancers has a very significant effect on the scoring of taste and the hedonics of color, taste, and overall acceptance, and has no significant effect on the aroma hedonics. The addition of flavor enhancer based on moringa leaves and tempeh with a percentage addition of 5% produces spinach clear soup with good sensory characteristics having a taste scoring value of 4.47 (very tasty), and color hedonics of 3.57 ( mildly like), aroma of 4.33 (mildly like), taste of 4.63 (like), and overall acceptance of 4.60 (like).

Abstract

Putu mayang cake is a traditional Indonesian snack originating from the Betawi. In general, putu mayang cakes are made from rice flour, but in terms of its benefits it is still lacking, so it is necessary to add other raw materials such as purple sweet potato. Purple sweet potato contains high fiber, and contains anthocyanin which acts as an antioxidant. The aim of this study was to determine the effect of the ratio of purple sweet potato flour to rice flour on the characteristics of putu mayang cakes, and to determine the best characteristics of putu mayang cakes. This study used a randomized block design (RBD) with 6 levels of treatment between of purple sweet potato flour and rice flour, namely P0 (0%:100%), P1 (4%:96%), P2 (8%:92%), P3 (12%:88%), P4 (16%:84%), P5 (20%:80%). Each treatment was repeated 3 times to obtain 18 experimental units. The data obtained will then be analyzed using ANOVA, and if it has a significant effect then it will be continued with Duncan's multiple range test. Based on the results of the comparison of purple sweet potato flour and rice flour on the characteristics of putu mayang cake. The best physicochemical characteristics in the treatment with a ratio of purple sweet potato flour (TUU) and rice flour (TB) were (12% TUU: 88% TB). The resulting characteristics are moisture content 51.79%, ash content 0.72%, crude fiber content 2.87%, total anthocyanin 1,89 mg/100g, antioxidant activity 27.20%, total phenol 0,73 mg/100mg, elasticity 19.39% , color test (L* 59.70; a* 11.37; b*-12.40), rather like color, rather like taste, rather like texture, slightly chewy texture intensity, and rather like overall acceptance.
