cocoa butter replacers from blends of mango seed fat extracted by supercritical carbon dioxide and palm stearin
Food Research International, 2014Co-Authors: M H A Jahurul, I S M Zaidul, N Nik A Norulaini, F Sahena, B Y Kamaruzzaman, Kashif Ghafoor, A K M OmarAbstract:Abstract Mango seeds are waste agro-industrial by-products produced in large quantities in the tropical countries. Supercritical fluid extraction was used for the extraction of high quality mango seed fat from mango seed wastes. The supercritical fluid extracted mango seed fat (MSF) was blended with palm stearin (PS) at different ratios to obtain cocoa butter replacers (CBRs). A total of 10 blends were formulated and the fatty acid constituents and physico-chemical properties of these blends were analyzed. Four blends of MSF/PS (90/10, 85/15, 80/20 and 75/25) possessed fatty acid constituents, iodine Value (41.8 to 42.4 g I2/100 g fat), Saponification Value (195.7 to 195.9 mg KOH/g fat), acid Value (2.4 to 2.9%) and slip melting point (37.7 to 39.9 °C) similar to those of commercial cocoa butter. Thus, these blends were considered recommendable as CBRs, due to their fatty acid constituents, iodine Value, slip melting point, Saponification Value, and acid Value consistent with cocoa butter.

Determination of Saponification Value in Carnuba Wax by USP/NF Residual Titration Method
American Journal of Analytical Chemistry, 2019Co-Authors: Stephanie Turnbull, Lauren Bradshaw, Yusuf YildizAbstract:Saponification Value is defined as mg KOH needed to neutralize free acids and saponify esters in 1 g of the test substance. A search of the literature showed that the standard Saponification methods of the U.S. Pharmacopeia, alcoholic potassium hydroxide were the only Saponification reagent. The sample to investigate is saponified with an excess of ethanolic potassium hydroxide solution. After finished Saponification the remaining excess of potassium hydroxide is determined by residual titration under Titrimetry , with aqueous volumetric hydrochloric acid. In this study, a test for Saponification Value has been successfully determined in carnuba wax. The average result has been found 90.9 mg KOH/g substance and, % RPD was 1.65%. This is in contradistinction to the U.S. Pharmacopeia/National Formulary (USP/ NF) Method.

theoretical modeling of iodine Value and Saponification Value of biodiesel fuels from their fatty acid composition
Renewable Energy, 2009Co-Authors: Ashwin Gopinath, Sukumar Puhan, G. NagarajanAbstract:Biodiesel is an alternative fuel consisting of alkyl esters of fatty acids from vegetable oils or animal fats. The properties of biodiesel depend on the type of vegetable oil used for the transesterification process. The objective of the present work is to theoretically predict the iodine Value and the Saponification Value of different biodiesels from their fatty acid methyl ester composition. The fatty acid ester compositions and the above Values of different biodiesels were taken from the available published data. A multiple linear regression model was developed to predict the iodine Value and Saponification Value of different biodiesels. The predicted results showed that the prediction errors were less than 3.4% compared to the available published data. The predicted Values were also verified by substituting in the available published model which was developed to predict the higher heating Values of biodiesel fuels from their iodine Value and the Saponification Value. The resulting heating Values of biodiesels were then compared with the published heating Values and reported.

Research on the Distribution Ratio and Separation Factor of Rare Earth and Aluminium in Chloronaphthenic Acid Extraction System
Rare Metals and Cemented Carbides, 2010Co-Authors: Wu Wen-yuanAbstract:The influences of extractant Saponification Value,solution acidity and Al concentration on the distribution ratio and separation factor of RE and Al in the chloronaphthenic acid system were studied.The results show that in the feed solution with high Al concentration,RE is separated effectively from Al by the above extraction system even under high solution acidity,where no emulsification occurs in the extraction process.And the optimal technological parameters of the extraction separation process are as follows:extractant Saponification Value 0.35 mol/L,Al concentration 12.5 mmol/L and pH=0.10.Under the above conditions,the distribution ratios of Al and RE are 0.53 and 0.05,respectively,and the separation factor of RE and Al is up to 10.6.

RESEARCH ON THE DISTRIBUTION RATIO AND SEPARATION COEFFICIENT OF RARE EARTH AND ALUMINIUM IN NAPHTHENIC ACID SYSTEM
Mining and Metallurgy, 2010Co-Authors: Wu Wen-yuanAbstract:The distribution ratio and separation coefficient of aluminium and rare earth in the naphthenic acid system are researched in the conditions of different extractant Saponification Value,different acidity and aluminium concentration in this article.The results show that in the condition of mid or high concentration of aluminium,the separation coefficient of aluminium and rare earth βAl/RE decrease dramatically with the increasing pH because of the increasing loss by solution of carboxylic acid and the emulsion problem caused by the hydrolyzed aluminum ion.By analysis and comparison,DAl=0.18,DRE=0.059 and βAl/RE=3.06 can be gained in the condition of 0.35M extractant Saponification Value,MAl=150mmol/L and pH=0.10,which is the optimizing process parameter in extracting aluminium and rare earth by the naphthenic acid system.
