Abstract

Monoglyceride (MG) is a compound containing one ester group (-COOR) with a long chain of fatty acids and two hydroxyl groups (-OH). MG is the most widely used compound as an emulsifier in the food industry. Emulsifier is a compound that has surface activity so that it can reduce surface tension and stabilize the emulsion. MG has the ability to reduce surface tension and can stabilize oil and water emulsions. MG can be synthesized through esterification of fatty acids with glycerol using an acid catalyst. Esterification reaction is an endothermal reaction that is reversible and the reaction conditions effect the conversion of the reaction obtained. The operating conditions in the esterification of fatty acids with glycerol effect the reaction conversion as well as the quality of the monoglycerides produced. MG production through esterification of fatty acids with reaction conversion and high purity has been found in the use of DES (deep eutectic solvent) as a catalyst. DES is stable and not volatile so that it can be used repeatedly (reused) without reducing its catalytic activity in the esterification of fatty acids for monoglyceride production. Keywords: DES, emulsifier, esterification, fatty acids, monoglyceride

Abstract

Monoglycerides and diglycerides are a form of emulsifier. Mono- and di-glycerides can be synthesized in various ways, one of which is esterification. In the esterification process, the use of a catalyst is very important in advance of the fatty acid conversion results. Homogeneous catalysts are mostly used in this process. Homogeneous catalysts are compounds that have the same phase as the reactants when a chemical reaction takes place. One of the newest forms of the catalyst with "green chemistry" status is DES (Deep Eutectic Solvents). NADES (Natural Deep Eutectic Solvents) is a DES solvent that uses abundant natural compounds and is ideal for DES because of its diversity of chemical properties, biodegradability, and non-toxicity. Keywords: Catalyst, DES, Emulsifier, NADES

Abstract

Mono-diacylglycerol (MDAG) is a type of emulsifier that is widely used in the food and nonfood industries. Monoglycerides are also biodegradable and can be used as additives in food because they provide good effects. Its use can be found in bakery products, foods with low fat content. MDAG can be produced from the esterification process. The advantages of this technique are that the esterification process takes place at a lower temperature than glycerolysis and a shorter time than enzymatic hydrolysis. In the research on the synthesis of mono-diacylglycerol from Palm Fatty Acid Distillate (PFAD) with glycerol, the best results were obtained at a temperature of 150 0C, yielding 74% yield, seeded at 160 0C, the emulsion stability value reached 72% with an ALB level of 39%. At a molar ratio of 1: 2, the MDAG brightness level was 85.57%. Keywords: Gliserol, Mono-diasilgliserol , PFAD

Abstract

Mono and diglycerides (MDAG) are a group of synthetic emulsifiers usually used for food emulsion. MDAG can be obtained by the esterification process of fatty acids and glycerol with Deep Eutectic Solvents (DES) as a catalyst. The re-used catalyst method is one of many methods to determine the effectiveness of DES as a catalyst in the esterification process. DES is a mixture of at least two components, there are Hydrogen Bond Acceptors (HBA) and Hydrogen Bond Donors (HBD) which form eutectic phases with a melting point is lower than the constituent component. Re-used catalyst DES was tested in optimum condition with temperature 150°C, 30 minutes reaction time, 5 wt% catalyst, with 6:1 ratio mol between glycerol and oleic acid, and the conversion is 95%. The result of 5 times re-used catalyst is the conversion has got a not too significant reduction, which indicates that the phosphonium-based DES catalyst has a strong resistance to maintaining high catalyst activity in the esterification process. Keywords: esterification, catalyst, DES, Emulsifier, re-used catalyst.

Abstract

Addition of corrosion inhibitor volume into mixing produce oil and water is the methode to protect the inner pipe that can support reliability of the system. The used inhibitor is a kind of organic inhibitor which is generally contain of amin and used to resist corrosion rate for carbon steel which is a pipe material to distribute mixing produce oil and water. The relationship of fluide flow rate and addition of inhibitor volume is very important to understand. One of its parameter is corrosion rate measurement using corrosion coupon. The purpose of this study is to understand the effect of fluide flow rate and addition of inhibitor volume and to find the best condition of corrosion rate in the system. From the experimental results can be concluded that the highest fluide flow rate can increase the corrosion rate. The addition of corrosion inhibitor volume can resist the corrosion rate. The 2,5 gal/day inhibitor was the best inhibitor volume to resist the corrosion rate at variant fluide floe rate, which is 0,3 MPY for 40.000 bbl/day, 0,44 MPY for 60.000 bbl/day, 0,7 MPY for 80.000 bbl/day.

Abstract

Monoglycerides (MG) and diglycerides (DG) are a group of synthetic emulsifiers that can be obtained from the process of esterification of fatty acids with glycerol using several types of acid-based catalysts, such as ZnO, zinc carboxylate, ZnCl2 and MgO. Recently, deep eutectic solvents (DESs) is used in the process of esterification replacing acid-based catalysts. DES is a system that consists of a mixture of at least two components: hydrogen bond acceptors (HBA) and hydrogen bond donors (HBD) which form eutectic phases that melting points are lower than the constituent components. DES application in the esterification process for the purpose of food grade takes into account the level of toxicity so that DES is made from the composition of green chemistry compounds known as NADES (Natural Deep Eutectic Solvents). NADES is a non-toxic DES group so that it can be applied in processing emulsifier raw materials as additives for food products. In addition, DES can be used repeatedly (reused catalyst) and the results show that the catalyst activity is well. The use of DES which acts as a catalyst and reused catalyst can save costs without reduced the conversion. Key words: DES, emulsifier, esterification, reused catalyst

Abstract

Liquid waste from processing cassava into tapioca starch is carbohydrate-rich waste and can be used as a growth medium for the Acetobacter xylinum, which is useful in producing one of the fermentation products, i.e. nata. Several factors influence the production of nata, one of them is the addition of nutrients in the form of nitrogen in the fermentation medium. The nitrogen source used is usually from inorganic fertilizers, such as urea and ammonium sulfate. In this study, fermentation of tapioca starch wastewater was developed, using a natural sources of nitrogen derived from soybean and green bean sprouts extract. Nata was made by treating various concentrations of soybean and green bean sprouts extract (3%, 4%, 5%) and fermentation time (6 days, 7 days, 8 days, 9 days and 10 days). The characteristics of the nata product were seen from the thickness and yield of the nata. The nata de cassava product's optimum results were tested for thickness, yield, and moisture content. The results showed that the best type of natural nitrogen source was soybean sprouts extract 5%, fermentation time of 10 days with a thickness of 0.55 cm, the water content of 97.58%, and yield of 63.09%

Abstract

Optimization is a way to find variable values that are considered optimal, effective, and efficient to achieve the desired results. The approach that is more often used for optimization problems with multi-variables is the desirability function. The components carried out by the optimization are microcrystalline cellulose (MCC) (x1), citric acid (x2), sorbitol (x3) with the response are Tensile Strength (Y1), Elongation (Y2), Modulus young (Y3), Biodegradability (Y4), and Water Uptake (Y5). Optimization is done by using Design Expert 10.0.1 Software. Through Desirability Function analysis, the optimum treatment composition was obtained at the MCC filler variation of 18% w / w starch, citric acid 3% w / w starch, and sorbitol 33% w / w starch with the optimum response value predicted for tensile strength (Y1) = 11.38 MPa; Elongation (Y2) = 13.54%; Young's modulus (Y3) = 118.05 MPa; Biodegradability (Y4) = 46.89%; and Water Uptake (Y5) = 52.13%. The combined desirability value is 0.551
