  PRODUCTION OF STRUCTURED LIPIDS FROM HAZELNUT OIL WITH CONJUGATED LINOLEIC ACID BY LIPASE-CATALYZED ESTERIFICATION: OPTIMIZATION BY RESPONSE SURFACE METHODOLOGY

  Bakir, N.; Ilyasoglu, H.; Yucetepe, A.; Kasapoglu, K. N.; Demircan, E.; Ozcelik, B.

  The aim of this study was to synthesize structured lipid from hazelnut oil with conjugated linoleic acid (CLA) by lipase-catalyzed esterification reaction. The incorporation of CLA into hazelnut oil was optimized by response surface methodology (RSM). Substrate molar ratio, time, and temperature were independent variables chosen for optimization of the reaction. Substrate molar ratio was the most significant variable on the incorporation of conjugated linoleic acid. Good quadratic model was achieved by multiple regression analysis and backward elimination. Optimal incorporation conditions were determined as follows: reaction temperature, 59 degrees C; time, 6 hours; substrate molar ratio, 4. Under these optimum conditions, a maximum incorporation ratio of CLA into hazelnut oil of 49.42% was achieved.

  Production of human milk fat substitute with medium-chain fatty acids by lipase-catalyzed acidolysis: Optimization by response surface methodology

  Ilyasoglu, Huri; Gultekin-Ozguven, Mine; Ozcelik, Beraat

  The aim of this study was to synthesize human milk fat substitute (HMFS) enriched with medium-chain fatty acids (MCFAs) by Lipozyme® RM IM-catalyzed acidolysis. The reaction substrates (tripalmitin, hazelnut oil fatty acids and Neobee® fatty acids) were specially chosen to mimic human milk fats and to enrich HMFS with MCFAs. Substrate molar ratio, reaction temperature and enzyme content were used to model and to optimize the reaction conditions via response surface methodology. The experiment was carried out at the optimal condition generated from the model yielded structured lipids with caprylic acid (12.8 g/100 g), capric acid (10.6 g/100 g) and palmitic acid (30 g/100 g). These values were found similar to the values predicted by the model (15.9 g/100 g, 14.1 g/100 g and 33.3 g/100 g). It can be concluded that the potential use of the structured lipids (SLs) produced in infant formulas provide energy source delivering a reduced calorie value for newborn, term and preterm infants.
