Abstract

Amla (Phyllanthus emblica) seeds have only been disposed of as waste and have not been utilized optimally. Utilizing the seeds to produce oil has been regarded as a promising approach for reducing solid wastes and producing value-added products. This study evaluated the effect of solid to solvent ratio and extraction time on yield, phytochemical content and physicochemical of oil extracted from amla seed using hexane as a solvent. The amla seed oil was extracted through the solid-liquid process at different solid to solvent ratios (1:20, 1:25 and 1:30 g/mL) and extraction times (30, 60, 90 and 120 minutes). The highest yield found was 10.97% at a solid to solvent ratio of 1:30 (g/mL) and an extraction time of 120 minutes. The highest concentrations of phenolic compounds and flavonoids were 66.12 mg GAE/g and 95.70 mg QE/g respectively, obtained at a solid to solvent ratio of 1:25 (g/mL) and extraction time of 120 minutes. Physicochemical analysis (pH, density, acid number, free fatty acid, and peroxide number) showed that the quality of extracted oil was better than what the previous study reported. In the amla seed oil, the content of unsaturated fatty acids was higher than saturated fatty acids with linoleate as the main component. These results clarified that solid-liquid extraction method can be used for extracting amla seed oil and also indicated that amla seed oil can be used as an ingredient in health-related industry products.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh rasio biji alpukat terhadap pelarut dan waktu ekstraksi pada proses ekstraksi minyak biji alpukat menggunakan pelarut n-heksan. Penelitian menggunakan rancangan acak kelompok dengan pola faktorial terdiri atas 2 faktor yang masing-masing terdiri dari 3 taraf dengan 3 kali ulangan. Faktor pertama adalah rasio biji alpukat terhadap pelarut yaitu 1:5, 1:10 dan 1:15 (g/mL), sedangkan faktor kedua adalah waktu ekstraksi yaitu 120, 150, dan 180 menit. Hasil sidik ragam menunjukkan bahwa perlakuan rasio bahan terhadap pelarut tidak berpengaruh nyata (P0,05) terhadap yield dan bilangan asam. Sementara itu, perlakuan waktu ekstraksi berpengaruh nyata (P0,05) terhadap yield minyak biji alpukat, dan berpengaruh tidak nyata (P0,05) terhadap bilangan asam. Yield tertinggi (2,23%) diperoleh dari sampel minyak pada perlakuan rasio bubuk biji alpukat terhadap pelarut 1:5 dan waktu ekstraksi 120 menit dengan aktivitas antioksidan 62,87%, serta nilai viskositas dan densitas masing-masing yaitu 13,5 cP dan 0,96 g/mL. Asam lemak oleat merupakan komponen terbesar dalam minyak biji alpukat.

Abstract

Biodiesel has been shown to be the best substitute for fossil-based fuels to its environmental advantages and renewable resource availability. There is a great demand for the commercialization of biodiesel production, which in turn calls for a technically and economically reactor technology. The production of biodiesel in existing batch and continuous-flow processes requires excess alcohol, typically 100%, over the stoichiometric molar requirement in order to drive the chemical reaction to completion. In this study, a novel reactor system using a reactive distillation (RD) technique was discussed for biodiesel production. RD is a chemical unit operation in which chemical reactions and separations occur simultaneously in one unit. It is an effective alternative to the classical combination of reactor and separation units especially when involving reversible or consecutive chemical reactions such as transesterication process in biodiesel production.

Abstract

Vacuum frying may be a good alternative for the production of dehydrated fruit and vegetable slices. In this study, a relationship between water losses with frying time during vacuum frying process of potato chips has been developed. A first order kinetic model was used, in which drying rate constant is a function of the main process variables, i.e. oil temperature, sample thickness and vacuum pressure. The experimental data of Garayo and Moreira (2000) have been used to validate the model. Generally there was a good agreement between the calculated results and the experimental data. Then, the effect of initial water content and vacuum pressure has been studied.Keywords: kinetic model, potato, vacuum frying, water loss

Abstract

The esterification of free fatty acids (FFA) found in crude palm oil (CPO) off grade with methanol is a promising technique to convert FFA into valuable fatty acid methyl ester (FAME, biodiesel) and obtain a FFA-free oil that can be further transesterified using alkali bases. In this work, the effects of the main variables involved in the esterification process i.e. alcohol to oil molar ratio, reaction temperature, agitation speed and the initial amount of FFA of oil, were studied in the presence of sulphuric acid as catalyst at concentration of 1%-w. The experimental results show that the esterification process could lead to a practical and cost effective FFA removal unit in front of typical oil transesterification for biodiesel production.Keywords: CPO off grade, esterification, free fatty acid

Abstract

Many commercial yogurt brands do not have a minimum total lactic acid bacteria count (107 CFU/g) due to long distribution with inappropriate storage condition. This leads local producers to produce yogurt. However, commercial yogurt maker machines commonly have a low capacity of 0.5 to 2 L. This study aims to design a yogurt maker machine with a capacity of 15 L with a temperature setting of 37 – 45 ℃. The design and flow system were conducted by arranging the electronic components consisting of 5V 4 channel relay, ESP32 module, DS18B20 temperature sensor, RTC, 12V fan (along with 12 VDC connecting components), 220V heater, 20×4 LCD and plugs (adapter) 220 VAC cable. The yogurt maker machine was evaluated for accuracy of temperature readings (DS18B20 sensor and thermometer), response to incubation time and plain yogurt making. The T-Test was used to compare the differences between the two types of sensors measuring instruments. The results showed that the accuracy of temperature readings using the DS18B20 sensor was better than a thermometer, with a distance scale of 0.35-0.75 ℃ (P-value ≤ 0.05). Temperature testing using milk can be carried out with a temperature range of 37-45 ℃ for 12 h. Keywords:  DS18B20, Temperature, Yogurt maker machine, Sensors
