Abstract

The waste of tea extraction has high content of polyphenol.  This waste can be processed to be natural brown food colorant that contains antioxidant.  Foam mat drying is a suitable method for producing natural brown food colorant.  Application of this food dye can be used as colorant agent in hipoglycemic biscuit that does not cause the increase of glucose blood level after consumption.  Wheat flour in the making of the biscuit was subtituted by suweg flour.  The suweg flour had lower glycaemic index than wheat flour.  The combination of natural brown food colorant contained antioxidant and suweg flour subtitution is expected to give functional effect for hypoglycaemic biscuit to prevent the increase of glucose blood level and has antioxidant property.The research comprised of two steps.  First step was dry colorant preparation and the second was application of dry colorant for hypoglycaemic biscuit.  The randomized block design was employed for each step with two variabels for each.  Experiment one: the variables were maltodextrin concentration (6%, 18% b/v) and egg white concentration (1%, 4%, 7% b/v). Experiment two: the variables were dry colorant concentration (2.5%, 5% b/b) and suweg flour-to-wheat flour subtitution level (8%, 24%, 40% b/b).   In the second experiment, hypoglycaemic biscuit was tested to wistar rats for determining its effectiveness in reducing blood glucose level compared to control.The result showed that the addition of maltodextrin in dry colorant preparatiom significantly affected antioxidant activity, total phenolic content, color, solubility, and water vapor absorption.  The best treatment of dry colorant based on physical and chemical parameters was 18% of maltodextrin concentration and 1% of egg white addition.  The characteristics of this dry colorant were as followed: 37.78% of antioxidant activity, 24.12 ppm of total phenolic content, 51.4 of brightness level, 0.074 g/sec of solubility, 8.03% of  water vapor absorption.  Meanwhile, the addition of egg white significantly affected antioxidant activity, total phenolic content, and color.  Subtitution of wheat flour by suweg flour significantly influenced biscuit color and reduced blood glucose level of rats.  The best treatment of hypoglycaemic biscuit based on physical, chemical, and bioassay parameters was obtained in 5% dry colorant addition and 10% suweg flour-to-wheat flour substitution level, with characteristics as followed: 35.95% of antioxidant activity, 3.8 ppm of  total penolic content, 44.4 of brightness level, 28 mg/dl of blood glucose level reduction.Keywords: the waste of tea extraction, dry colorant containing antioxidant, suweg flour, hipoglycaemic biscuit

Abstract

The analysis of soil characteristics are time consuming, cost highly, and the results are qualitative. Analysis of soil characteristics might be conducted through the fractal theory. Fractal description of soil based on the pore space and the distribution of particles is a useful way to make quantitative analysis of soil structure.D value is determined by a mathematical equation of the curve of water retention. The water retention curve is obtained from some values of D and then compared to the data from entisol soil analysis. The results are calculated based on the size and the mass class cumulative value obtained from fractal dimension (Dm) estimation of 1.87 ± 0.225.  The water retention curve models are obtained with a quite good value at D = 2.052.  There is a converse relationship between water content and water suction.  The greater water content, the less water suction, and vice versa.   This is shown in the regression linier model equation of y = 12744x2 - 8666x + 1239.6 with a determination coefficient R2 = 0.8252.  The value of water retention from the model is approximate the analytical data as shown in the linear regression from analysis of soil y = 12910x2 - 8751.9x + 1222 with determination coefficient R2 = 0.805.  The linear regression equation of the model is y = 12744x2 - 8666x + 1239.6 with a determination coefficient R2 = 0.8252.Key word: fractal theory, water retention, entisol soil

Abstract

Dioscorea hispida Dennst. or gadung-yam is one of the tuber crops in Indonesia. Nevertheless, people are still unaware to consume gadung-yam and its derivative product, because of toxic compounds such as alkaloid and cyanide. Therefore, it is necessary to have a detoxification process to decrease the concentration of cyanide to have safe product of gadung-yam such as gadung flour. A detoxification can be carried out by a fermentation method, which accelerates the breakdown of cyanides. The fermentation will produce more volatile HCN in gadung flour which evaporate in drying process. The fermentation in this research used Mucor sp. The objective of this research was to obtain the optimum concentration of Mucor sp. and the the fermentation time to produce less cyanide gadung flour. The experimental design of the research was Factorial Randomized Block Design with two factors. The first factor was the concentration of mold with four levels, i.e. 0%, 5%, 10%, and 15%. The second factor was the fermentation time with 3 levels i.e. 24, 48 and 72 jam. The data was analyzed using anova followed by LSD or DMRT test with  = 0.05.The results showed that there was significant interaction between the mold concentration and the fermentation time on starch, reducing sugar, total sugar, and fiber content.  However, there was no significant interaction between treatments on moisture and cyanide content. The best treatment was the combination of 5% mold and 72 hours fermentation.  The characteristic of this gadung-flour were 4.01% of moisture content, 21.74 ppm of cyanide content; 46.66% of starch content; 3.6% of fiber content; 17.00% of total sugar content; 9.52% reducing sugar content; L* colour of 60.97; a* of 13.27; b* of 18.45;  3.27% of higroscopicity, and starch gelatinization temperature of 83ºC.Keywords: gadung, detoxification, yams flour, fermentation, Mucor sp.

Abstract

Many researchers reported that seaweeds are important sources of alginate. This article reports on alginate content of seaweeds grown in coastal zone of Lombok extracted by two methods.  The seaweeds were collected at several sampling points in coastal zone of Lombok, identified and analyzed their alginate content. The result shows that there were no significant different in alginate content of samples extracted using both procedures. However, only the brown species produced alginate.  The alginate content more than 10% was obtained from the species of Padina sp., Dictyota sp. 1, Dictyota sp. 2, Sargassum polycistum 1, Turbinaria ornate, and Turbinaria murayana. Whereas, the alginate content less than 10% obtained from the species of Sargassum aquifolium, Sargassum sp., Turbinaria conoides, S. crassifolium, S. polycistum 2, S. Cristaefolium, and Hormophysa sp.. Therefore, it can be concluded that only the brown seaweeds had potency as alginate sources.  It needed to analyze physical and chemical characteristics of this alginate related to its quality and functional application.Keywords: alginate, seaweed, extraction methods
