A chocolate having good solidification properties, a high mold releasability and a high crystal stabilization rate, said chocolate being obtained by using an oil or fat composition wherein StOSt and POP triglycerides are contained each in a definite amount or more and StLSt, PLP, StStO and PPO triglycerides are contained each in a definite amount or less. As a result, the productivity of the chocolate can be increased.

Provided is a powdered chocolate containing a fat and/or oil composition in a powder form wherein the fat and/or oil composition contains: 65 to 99% by mass of a XXX triglyceride having fatty acid residues X, each with x carbon atoms, at positions 1 to 3; and 35 to 1% by mass of one or more types of X2Y triglycerides each having a fatty acid residue Y with y carbon atoms in place of one of the fatty acid residues X of the XXX triglyceride, provided that a total triglyceride content is 100% by mass, where x number of carbon atoms is an integer selected from 8 to 20, and y number of carbon atoms is each independently an integer selected from x+2 to x+12 and satisfying y22.

The present invention provides a commercially-viable-level, highly efficient production method for oil and fat that are rich in USU.

Provided herein are processes for preparing estolides and estolide base oils from fatty acid reactants utilizing catalysts. Further provided herein are processes for preparing carboxylic esters from at least one carboxylic acid reactant and at least one olefin.

Embodiments of the present invention relate to drilling oil, and to a method of preparing the drilling oil, including converting C16 and/or C18 fatty acids derived from fat of biological origin into C15 and/or C17 olefins through decarbonylation.

An object of the present invention is to provide oils and fats which include constituent fatty acids containing a large amount of n-decanoic acid, scarcely cause discomfort when ingested, and have excellent cold resistance. The present invention provides oils and fats, in which the content of tridecanoin is 30% by mass or less, the content of medium chain fatty acids contained in the constituent fatty acids is 65 to 95% by mass, and the content of n-decanoic acid contained in the medium chain fatty acids is 50% by mass or more. Furthermore, the present invention provides oils and fats in which the content of unsaturated fatty acids contained in the constituent fatty acids of the oils and fats is 3 to 35% by mass.
