Abstract

Coriander is one of the natural antioxidant sources that can be used as chelating agent of heavy metals, such as lead (Pb) due to the presence of its phenolic compounds. However, the coriander has only been used as one of the spices on some dishes, and the other potential benefits have not been widely explored. Therefore, the processing of coriander leaves into a ready-to-drink (RTD) powdered beverage would be one of the ways to utilize the coriander. The objective of this study was to analyze the effect of drying temperature and maltodextrin concentration on product quality of powder drink. This study applied a complete randomized design of factorial pattern with two factors. The first factor was the drying temperature of 40oC, 50oC, and 60oC, while the second factor was the addition of maltodextrin as filler with the concentration of 5%, 10%, and 15%. The optimum treatment was observed at drying temperature of 40oC with maltodextrin concentration of 15%, yielding powder drink with water content of 4.19%; solubility of 89.92%; total phenol of 131.93 mg TAE/g; primary antioxidant activity of 47.05%; secondary antioxidant activity of 79.30%; and Pb reduction ability of 95.36%.

Abstract

Geothermal sludge is a waste product from geothermal where it contains SiO2 which can be used as fertilizer. In this study, the making of silica ammonium fertilizer was carried out by taking salicy acid from geothermal sludge by extracting and adding resin which was then modified with NH4OH addition. Extraction was done using 1000 ml of KOH 1 N to dissolve 60 grams of Geothermal Sludge. Resins are added with variations in resin weight, namely, 5, 10, 20, 30, and 40 grams. NH4OH was added with variations in concentrations namely 3, 6, 9, 12 and 15% with a ratio of filtrate and NH4OH solution of 1: 1. The resulting ammonium silica inorganic liquid fertilizer products were analyzed for free silica and ammonia levels. The results of this study indicate that the levels of free silica and ammonia are influenced by the weight of the resin used and the concentration of ammonium hydroxide mixed. From the results of the research, it was found that inorganic silica liquid fertilizer with the highest SiO2 content in ammonium silica liquid fertilizer occurred when adding 20 grams of resin with the addition of NH4OH with a concentration of 15% which was 1,831.87 mg / L while the highest NH3 content in fertilizer liquid ammonium silica occurs when adding 40 grams of resin with the addition of NH4OH with a concentration of 15% which is equal to 252,312.80 mg / L.

Abstract

Mango is a common fruit in tropical countries. Due to its short shelf-life, it is important to study alternative preservation and consumption methods. In this study, concentrated mango juice was used to produce mango powder by using spray drying process. Four process parameters with three levels variation each, including initial total soluble solid content (13, 14, 15◦Brix), maltodextrin content (20, 25, 30% w/w), inlet air temperature (170, 190, 210◦C), and atomization pressure (4, 5, 6 bar) were studied. Taguchi approach of L-9 (34) array was used to design the experiments. Powder yield, moisture content, color difference, and solubility of the mango powder were investigated. It was found that maltodextrin content was the greatest factor affecting powder yield and color difference. The highest powder yield was 31.81%, and the least color difference (∆E) was 3.17. Inlet air temperature and atomization pressure were the most important factor affecting to moisture content and solubility, respectively, in which average moisture content was 2.98% (w.b.) and the highest solubility value was 94.66%. For the overall production process, it was concluded that maltodextrin content was the most important parameter, while total soluble solid content provided the least impact on spray dried mango powder properties.

Abstract

Cooking oil can only be used two or three times, more than that the oil is deemed unsuitable and can harm our health. The reason is, every time the cooking oil is used for frying, an oxidation reaction that is triggered by heat occured and causes the chemical chain bonds in cooking oil become unstable and forms hydroperoxides. The hydroperoxide found in used cooking oil increases the peroxide value. In which, the suitability of cooking oil is based on the peroxide value. In order to reduce the peroxide value in used cooking oil, in this study, Ampo is used as an adsorbent to adsorb the peroxide compound. The procedure used in this study includes a preliminary analysis of the used cooking oil to determine the initial peroxide value. After that, the Ampo adsorbent is activated with 1N Citric Acid to open the pores on the surface of the Ampo. Activated Ampo will then be mixed into 200 ml of used cooking oil with a magnetic stirrer with a stirring speed of 300 rpm and with a temperature of 50oC. The adsorption process was carried out by varying the mass variables of Ampo into 70, 75, 80, 85, and 90 grams, and stirring time of 30, 60, 90, 120, and 150 minutes. After the adsorption process is completed, the cooking oil that has been filtered by the Ampo adsorbent will be analyzed to get the final peroxide value. By knowing the peroxide value before and after the adsorption process, the adsorption isotherm can be calculated. The adsorption process of used cooking oil with Ampo adsorbent proved to reduce the peroxide value, in which stirring times and adsorbent masses were the influential variables in the study. The best result was obtained with 60 minutes stirring time and mass of 75 grams. This condition provided a peroxide value of 0.99 meq/kg, which means that there was a decrease in the peroxide value by 93%. This result is in accordance with the provisions of SNI 3741-2013, with a maximum peroxide value of 10 meq/kg. The maximum adsorption capacity in this study was obtained from the Freundlich equation of 14.6487 mg/gram.
