Abstract

This study aims to determine the effect of processing methods on antioxidant activity and characteristics of African leaf herbal tea and find out the right processing method to get the highest antioxidant activity and the best characteristics. The Completely Randomized Design was used in this study with treatment methods which consisted of 4 levels, namely Method A (steam blanching and drying), Method B (withering and pan firing) Method C (withering and Drying) and Method D (steam blanching and pan firing). This study was repeated 4 times to obtain 16 experimental units. The data obtained were analyzed by analysis of variance and if the treatment had a significant effect it was followed by Duncan’s Multiple Range Test (DMRT). The parameters tested in this study include water content, ash content, total phenols, total flavonoids, color, antioxidant activity and sensory characteristics. The results showed that the methods of processing herbal tea powder of African leaves has a highly significant effect on water content, total phenol, total flavonoids, antioxidant activity, color, and sensory tests of color, taste, flavor and have a significant effect on overall reception and have no significant effect on ash content. Herbal tea powder of African leaves processed by method steaming and drying was the best treatment with a moisture content of 6.41%, ash content of 5.27%, total phenol of 2.4169 mgGAE/g, total flavonoids 2, 6563 mgQE/g, antioxidant activity 67.28%, color (L, a, b = 4.86; -49.07; 34.71), light green color, very distinctive aroma of African tea leaves, very bitter taste, and overall reception likes.

Abstract

This study aims to determine the effect of storage at room temperature and cold on shelf life and nutritional value of Barjaz Red Rice Tea and to determine the shelf life of Barjaz Red Rice Tea in storage at room temperature and cold. This study uses an experimental method with a quota sampling technique, in which the researcher has first determined the number of samples to be studied. Samples of Barjaz Red Rice Tea were taken from the Barjaz Tea production house located in Denpasar City, Bali Province. Barjaz Red Rice Tea parameters observed included total plate count, total sugar, anthocyanin content, antioxidant activity, and sensory assessment. The parameters studied were then analyzed using descriptive methods and the research data were presented in tabular form. The results showed that the shelf life and storage temperature had increase in the total plate number of Barjaz Red Rice Tea. Along with the long shelf life and high storage temperatures, the total plate number of Barjaz Red Rice Tea is getting higher. Based on total plate numbers, Barjaz Red Rice Tea that meets SNI 01-3143-1992 standards is Barjaz Red Rice Tea which is stored for zero days at room temperature and seven days at cold temperatures. Shelf life and storage temperature decrease the total sugar, anthocyanin levels, and antioxidant activity of Barjaz Red Rice Tea. Along with the long shelf life and high storage temperature, the total sugar, anthocyanin content, and antioxidant activity of Barjaz Red Rice Tea will decrease. The total sugar samples of Barjaz Red Rice Tea, both stored at room temperature and cold temperatures, still meet the standards set by SNI 01-3143-1992. Storage temperature influenced panelists' assessment of the sensory evaluation of color, aroma, taste and overall assessment of Barjaz Red Rice Tea. The criteria for Barjaz Red Rice Tea that are still suitable for consumption and favored by panelists are those that have a dark red color, a distinctive aroma of red rice tea, and a slightly sweet taste.

Abstract

Donuts are flour based foods. The weakness of donuts is that the basic ingredients used are still imported, so there is an increase in the use of alternative flour, namely millet flour. The research aims to find out the ratio effect of wheat and millet flour to the characteristic of donut, and to determine the precise ratio between wheat and millet flour which can produce donuts with the best characteristic. This research used a Completely Randomized Design with a treatmen of ratio between wheat flour and millet flour which consist by 6 levels: 100%:0%, 90%:10%, 80%:20%, 70%:30%, 60%:40%, and 50%:50%. The treatment was repeated 3 times to obtain 18 experimental units. The data obtained were analyzed by variance and if treatment had a significant effect then followed by duncan test. The result of research showed that the ratio of 80% wheat and 20% millet flour resulted in the best characteristic of donut with expand power of 116,69%, colour quantity L 52,77, a* 9,51, b*34,37, water content of 25.88% (wb), protein content of 8.17% (wb), crude fiber content of 5,06% (wb), tannin content of 0,15% (wb), colour golden yellow, flavor rather liked, texture rather liked and soft, appearance of rather large pores, taste rather liked and overall acceptance rather liked.

Abstract

“Jamu Gendong Kunyit Asam (Tamarind Turmeric Sour Herbs)” is a typical Indonesian drink that is quite famous which is one of the legacies of the Indonesian nation’s ancestors who have medicinal properties in maintaining health and for healing a disease. This study aims to determine aspects of chemistry and microbiology as well as food safety of Tamarind Turmeric Sour Herbs in Jimbaran and Kedonganan, Bali by using survey method and research. The observed variabels include total microbial, coliforms, Escherichia coli, pH, total acid, total vitamin C. The results of microbiological aspect test in this study showed that two samples of Jamu Gendong Kunyit Asam (Tamarind Turmeric Sour Herbs) at Jimbaran and Kedonganan,Bali does not meet the requirements according to SNI 7388:2009 namely samples B and E with indigo in sample B that is 30 x 10-1 and sample E which is 1 x 10-1. The result of chemistry aspect are if the increase in total vitamin C will effect the increase in total acid and pH will be more acid. Besaide that, E. coli bacteria can grow at a pH of 5-7 and the compound content of the tamarind fruit is also antibacterial so that most of Jamu Gendong Kunyit Asam (Tamarind Turmeric Sour Herbs) at Jimbaran and Kedonganan are not contaminated with E.coli.

Abstract

This research aimed to determine the effect of drying temperature and time on the chemical and sensory properties of kenikir leaf tea bags and the optimum drying temperature and time for producing the tea bag. This research used a factorial experiment with a Completely Randomized Design (CRD) consisting of two factors. The first factor was the drying temperature (400C, 500C, and 600C), and the second was drying time (3.0, 3.5, and 4 hours). The treatment was repeated twice so that 18 experimental units were obtained. The data obtained were analyzed using the Analysis of Variance (ANOVA), and if it shows significant result, the Duncan Multiple Range Test was carried out. The results showed that the interaction between drying temperature and drying time was significant effect on water content, total phenol, total flavonoid, antioxidant activity, and sensory properties. The temperature of 500C for 3.5 hours was the best treatment, which produced the sensory properties of the brewed tea for the typical kenikir tea aroma were preferred, the rather-bitter and neutral for tastes, the greenish-yellow for color were preferred, and the overall-acceptance were neutral, with antioxidant capacity of 86.36%, water extract of 32.58%, total phenol of 1.45% mg GAE/g, flavonoid content of 0.29 mg QE/g, and water content of 9.18%.
