TLDR
Composition of free fatty acids and smoke point of RBO and RBOSL were not significantly different, while melting end point temperatures and melting enthalpies were significantly different.Abstract:
Rice bran oil (RBO) was enzymatically modified in a continuous packed bed bioreactor to incorporate caprylic acid with Lipozyme RM IM as biocatalyst. The reaction product was purified by short-path distillation. Rice bran oil structured lipid (RBOSL) contained 32.1 mol % caprylic acid. Positional analysis revealed 0.7 mol % caprylic acid at the sn-2 position and 47.8 mol % caprylic acid at the sn-1,3 positions. Composition of free fatty acids and smoke point of RBO and RBOSL were not significantly different. Saponification value, iodine value, and viscosity of RBO were significantly different from those of RBOSL. The color of RBOSL was darker, more yellow and less green than RBO. Volatile compounds in RBO and RBOSL were determined by GC-MS. Melting onset temperatures of RBO and RBOSL were not significantly different, while melting end point temperatures and melting enthalpies were significantly different. This characterization study results will help determine potential food applications of RBOSL.read more

Physiological Effects of Medium-Chain Triglycerides: Potential Agents in the Prevention of Obesity
TL;DR: From the literature reviewed, it is concluded that MCT increase energy expenditure, may result in faster satiety and facilitate weight control when included in the diet as a replacement for fats containing LCT.

Medium-chain triglycerides increase energy expenditure and decrease adiposity in overweight men.
TL;DR: Consumption of a diet rich in MCTs results in greater loss of AT compared with LCTs, perhaps due to increased energy expenditure and fat oxidation observed with MCT intake, which may help in the prevention of obesity or potentially stimulate weight loss.

Influence of chemical refining on the major and minor components of rice brain oil
TL;DR: In this paper, the effects of each individual step of the chemical refining process on major and minor components of rice bran oil were examined, and the results showed that rice brain oil contains a significantly higher level of several bioactive minor components such as γ-oryzanol, tocotrienols, and phytosterols.

The rapid hydrolysis and efficient absorption of triglycerides with octanoic acid in the 1 and 3 positions and long-chain fatty acid in the 2 position.
TL;DR: Empirical data support the ease of hydrolysis and absorption of 1,3-dioctanoyl triglycerides with long-chain fatty acids in the 2 position, which is more rapidly hydrolyzed than triglycerides comprising all long- chain fatty acids.
