A method for caring for or treating the breasts during premenstrual or menstrual phases and for the care or treatment of the symptomatology of mastodynia, comprising a step of selecting or identifying women needing care or treatment of the breasts, or suffering from symptomatology of mastodynia, and a step of applying to the skin areas in need thereof an effective amount of a product, active agent or composition, comprising peroxidized lipids or a peroxidised oil, or consisting essentially of peroxidized lipids or of a peroxidised oil.

The present invention relates to extracted plant lipid, comprising fatty acids in an esterified form.

A method of preparing an edible randomly interesterified fat product comprises the steps of: a) providing a fat composition comprising from 0.5% to 25% by weight of free fatty acids; and b) reacting enzymatically the fat composition provided in step a) with from 0.5% to 10% by weight of a polyol compound based on the fat composition, wherein the weight ratio of free fatty acid in the fat composition to the polyol composition is from 0.1 to 20.0; and wherein the obtained randomly interesterified fat product has less than 1.0% by weight of free fatty acids.

An enzymatic glycerolysis method to convert an oil having a first monoacylgycerol (MAG), diacylglycerol (DAG), triacylglycerol (TAG) and fatty acid composition into a structured fat is provided. The method comprising the steps of exposing the oil to glycerol in the presence of an enzyme catalyst under conditions sufficient to convert the triacylglycerols to mono- and/or di-acylglycerols; and cooling the oil to yield the structured fat having a second monoacylgycerol, diacylglycerol, triacylglycerol and fatty acid composition, wherein the fatty acid composition of the oil is essentially retained in the structured fat. The structured fat provides a healthy substitute for saturated fats in foods.

Disclosed is a method for preparing bio-oil, which can be used as bio heavy fuel oil and bio marine oil, from a fatty acid with high acid value. The method for preparing bio-oil comprises the steps of: inputting materials comprising glycerine and a fatty acid into respective material input ports positioned in the center of a column-type reactor and esterification reacting the material comprising glycerine and fatty acid in each tray of a reaction area, thereby producing glyceride and water, wherein the column-type reactor has the plurality of trays installed inside the reactor so as to form a plurality of compartments in the vertical direction inside the reactor, openings are formed in the plurality of trays to connect the compartments which are vertically adjacent, and the openings of the adjacent compartments are alternately formed in a crisscrossing manner; obtaining the produced glyceride through a lower part of the reactor; and vaporizing the water produced by the esterification reaction, moving the water in a vapor state to a distillation area in an upper part of the reactor to separate the water from active components (reaction material and bio-oil) comprised in the vapor, allowing the separated active components to flow into the reaction area, and removing the separated water through the upper part of the reactor in a vapor state. The acid value of the glyceride is 30 mgKOH/g or lower, and the esterification reaction is performed at a reaction temperature of 200 to 250° C. and at ordinary pressure without using a catalyst.

Implementations of a process for forming esters of polyols may include mixing a polyol with a triglyceride in a reactor at a 2.5-6:1 molar ratio of polyol to triglyceride to form an input; mixing the input with isopropanol to form a diluted input; mixing a catalyst with the diluted input; and heating and agitating the diluted input to form a product including monoesters of the triglyceride and the polyol.
