Purification and separation of glucomannan from porang tuber flour () using microwave assisted extraction as an innovative gelatine substituent.

Gelatine is frequently used as a food ingredient. However, Indonesia imports almost all of its gelatine, totaling 3990152 tons annually. Gelatine could be replaced with glucomannan compound which was found in porang tubers.

Synthesis of Cellulose Nanocrystals/HKUST-1 Composites and Their Applications: Crystal Violet Removal and Doxorubicin Loading.

This study developed a novel composite material containing cellulose nanocrystals (CNCs) and HKUST-1. Here, the addition of CNCs was used to enhance the characteristics of HKUST-1 in terms of surface area, adsorption ability, and functional groups. Here, the fabrication of CNCs@HKUST-1 composites was carried out by adding CNCs into the fabrication process of HKUST-1.

Optimization and kinetic study of biodiesel production from nyamplung oil with microwave-assisted extraction (MAE) technique.

Nyamplung oil (), which has a high oil content and non-edible, has a lot of potential as a raw material in the production of biodiesel. Therefore, it has no impact on food security. In this research, response surface methodology was used to find the optimum conditions of biodiesel production from nyamplung, and the kinetics model of esterification reaction of free fatty acid (FFA) in the MAE method was determined.

Statistically Optimum HKUST-1 Synthesized by Room Temperature Coordination Modulation Method for the Adsorption of Crystal Violet Dye.

Due to its excellency and versatility, many synthesis methods and conditions were developed to produce HKUST-1 ([Cu(BTC)(HO)]). However, the diversity of HKUST-1 was actually generated both in terms of characteristics and morphologies. Hence, the consistency of HKUST-1 characteristics and morphologies needs to be maintained.

Facile and Green Synthesis of Starfruit-Like ZIF-L, and Its Optimization Study.

Due to its excellent characteristics, zeolitic imidazole framework-L (ZIF-L) is widely used in various applications, such as drug delivery, wastewater treatments and energy storage. In the synthesis of ZIF-L, the molar ratio of ligand to metal, the reaction time and the temperature are essential parameters to produce excellent ZIF-L. In this work, ZIF-L was synthesized using a facile and green synthesis method.

A Review of Lignocellulosic-Derived Nanoparticles for Drug Delivery Applications: Lignin Nanoparticles, Xylan Nanoparticles, and Cellulose Nanocrystals.

Due to their biocompatibility, biodegradability, and non-toxicity, lignocellulosic-derived nanoparticles are very potential materials for drug carriers in drug delivery applications. There are three main lignocellulosic-derived nanoparticles discussed in this review. First, lignin nanoparticles (LNPs) are an amphiphilic nanoparticle which has versatile interactions toward hydrophilic or hydrophobic drugs.

Hydrophobic Modification of Cellulose Nanocrystals from Bamboo Shoots Using Rarasaponins.

Because of their hydrophilic tendencies, the modification of cellulose nanocrystals (CNCs) is needed for applying them as a hydrophobic drug carrier. Previous studies have investigated several modification agents, such as cetyltrimethylammonium bromide. Natural surfactants, such as rarasaponins (RSs), are suitable to avoid human health and environmental issues.

The highest population of is in Indonesia. One of the bioactive compound contained in leave is cholestane. The extraction method was employed to obtain crude extract from these leaves.

Optimization of cellulose nanocrystals from bamboo shoots using Response Surface Methodology.

Cellulose-based advanced materials, such as cellulose nanocrystals (CNC), have high potential application for drug delivery system. In this study, the CNC were produced from bamboo shoots using acid hydrolysis process. The delignification of bamboo shoots was conducted using alkali and hydrogen peroxide pretreatment processes.

Optimization of process conditions for tannin content reduction in cassava leaves during solid state fermentation using .

Cassava leaves are a crucial source of alternative protein resources for both humans and livestock in developing societies in African and Asian countries that do not have easy access to available protein sources. Hence, cassava has the capacity to promote the economic development of these countries and provide food security. However, it has some disadvantages due to the anti-nutrient compounds present in its tissues, which limits the nutritional value of cassava leaves.

Kinetic data of extraction of cyanide during the soaking process of cassava leaves.

With the toxicity problems arising from the consumption of hydrogen cyanide (HCN), an acceptable method of processing edible leaves with low HCN level while maintaining maximum nutritional content remain a challenge. This data focuses on the extraction kinetics of cyanide in cassava leaves during the soaking process. Various process parameters conducted at 26 ± 2 °C were evaluated, such as contact times (1-20 h) between the leaves and solvent, as well as the water-to-leaves ratios (spanning a range of 10-50 mL/g).

Irresolvable complex mixture of hydrocarbons in soybean oil deodorizer distillate.

Aliphatic hydrocarbons (HCs) can be used as a fingerprint of a given seed oil. Only by characterization of aliphatic HCs could contamination by mineral oil in that seed oil be confirmed. During the isolation of squalene from soybean oil deodorizer distillate, a significant amount of unknown HCs, ca.

Biodiesel production from rice bran by a two-step in-situ process.

The production of fatty acid methyl esters (FAMEs) by a two-step in-situ transesterification from two kinds of rice bran was investigated in this study. The method included an in-situ acid-catalyzed esterification followed by an in-situ base-catalyzed transesterification. Free fatty acids (FFAs) level was reduced to less than 1% for both rice bran A (initial FFAs content=3%) and rice bran B (initial FFAs content=30%) in the first step under the following conditions: 10 g rice bran, methanol to rice bran ratio 15 mL/g, H(2)SO(4) to rice bran mass ratio 0.

Biodiesel production from rice bran oil and supercritical methanol.

In this study, production of biodiesel from low cost raw materials, such as rice bran and dewaxed-degummed rice bran oil (DDRBO), under supercritical condition was carried out. Carbon dioxide (CO2) was employed as co-solvent to decrease the supercritical temperature and pressure of methanol. The effects of different raw materials on the yield of biodiesel production were investigated.
