This study aimed to synthesize structured lipids containing high mono- and diacylglycerol by glycerolysis-interesterification of palm olein and coconut oil blend in two high-shear continuous stirred tank reactors in series. The result showed that various flow rates of 11 mL/min to 23 mL/min did not significantly increase mono- and diacylglycerol concentration, while at a flow rate of 26 mL/min only a low concentration of mono- and diacylglycerol was formed. However, a flow rate 20 mL/min and an agitating speed of 2000 rpm produced mono- and diacylglycerol concentration of 61.7% with the highest productivity of 2.1%/min and a triacylglycerol conversion of 64.6%. The slip melting point, melting point, hardness, emulsion capacity, and stability were 23.77 °C, 30 °C, 14.6 N, 65.15%, and 59.15%, respectively. The product’s solid fat content at 25 °C was lower than cocoa butter. The product contained β’ and β crystals, thus it can be applied as a cocoa butter substitute.

Providing more and more energy is an essential task of today's energetic industry. In the last few years, addition to traditional methods of energy production, alternative energy sources have been fast developing. One of the devices that can use these sources is fuel cell. The fuel cells can be a power source of future mainly due to their high efficiency, low influence on environment and possibility of powering with different fuels. Most often fuel cells are powered by hydrogen. However, problems with the problems with its cheap production and storage are the reason for the search of new fuels for fuel cells. But it must be a fuel that will provide zero or low emission level. One of these fuels can be vegetable oil. The paper presents measurements of electrooxidation of coconut oil emulsion on a smooth platinum electrode in an aqueous solution of KOH. Electrochemical measurements were performed in a glass cell with AMEL System 5000 potentiostat. The obtained maximum current density is equal 25 mA/cm2. So, a fundamental possibility of using the coconut oil as fuel for fuel cell. But is necessary to keep the temperature of process above 303K.

In this chapter, an isocratic reverse phase HPLC determination of mimosine was developed and validated in an anti-psoriatic topically applied formulation “Lajjalu”. The chromatography was performed on a C18 column with water-orthophosphoric acid (98.8:0.2, υ/υ) as a mobile phase with a pH of 3.0 at a flow rate of 1.0 mL min-1. Detection was performed at 284 nm, and a sharp peak was obtained for mimosine at a retention time of 2.62 ± 0.01 min. Linear regression analysis data for the calibration plot showed a good linear relationship between response curve and concentration in the range of 0.050–5000 ng mL-1 and the regression coefficient was 0.9998 with the linear regression equation y = 4766.8x−17726. The detection (LOD) and quantification (LOQ) limits were 10.3 and 35.6 ng mL-1, respectively. The wide linearity range, sensitivity, accuracy, short retention time, and simple mobile phase imply the method is suitable for routine quantification of mimosine with high precision and accuracy.
