This disclosure provides a triglyceride oil possessing an extremely low cloud point and low viscosity concomitant with a higher than anticipated saturated fatty acid content, very low polyunsaturated fatty acid content, and low iodine value. While many naturally occurring triglyceride oils possess one or more of these properties, natural triglyceride oils lack one or more of these attributes, thus making them less than ideal in industrial applications, such as lubricants, fuels, or dielectric fluids. The combination of attributes possessed by a triglyceride oil described herein, achieved without the addition of any additives, is unique compared with natural counterparts and as such, can find wide applications in the aforementioned fields.

Provided is a fat or oil composition that enhances sweetness. The fat or oil composition includes the following components (A), (B), and (C): (A) 0.10 mass % or more and 1.50 mass % or less of free α-linolenic acid; (B) 0.3 mass % or more and 1.5 mass % or less of α-linolenic acid monoacylglycerol; and (C) 65 mass % or more of diacylglycerols, wherein a content mass ratio of the component (A) to the component (B), [(A)/(B)], is 0.10 or more and 3.00 or less.

The present invention relates to a method for preparing low-sulfur biodiesel. The method includes the following steps: subjecting raw crude oil to heat exchange, preheating, glycerol esterification reaction, flashing, cooling, transesterification, dealcoholization, sedimentation, and methyl ester rectification to obtain low-sulfur biodiesel up to the standard, where in the heat exchange process, the raw crude oil exchanges heat with flashed oil to recycle some heat, and glycerol and fatty acids in a distilled product subjected to flashing are reused for the glycerol esterification reaction; the dealcoholization process removes methanol in a system after the transesterification, and refined methanol recycled by methanol rectification is reused for the transesterification reaction; crude glycerol generated in the sedimentation process does not need to be treated and is directly used for glycerol rectification to obtain refined glycerol, and the refined glycerol is reused for the glycerol esterification reaction.
