Problems solved by technology

However, although super oil can greatly reduce the high melting point triglyceride components, its cloud point is only a few degrees Celsius, and it will precipitate and crystallize in the refrigerator or cold area, or when stored in winter, making it a household oil with important transparency. It is difficult to commercialize liquid oils such as

Embodiment 1( Synthetic example 1

[0063] Add 200 g of polyglycerol (GREAT OIL (Great Oil) KT-1) made by Sun Chemical Co., Ltd. and 600 mL of pyridine. To this was added 370 g of chlorotrityl (manufactured by Wako Pure Chemical Industries, Ltd.), a reagent that selectively reacts with primary hydroxyl groups, stirred at 100° C. for 1 hour, and further stirred for 24 hours after cooling to room temperature (25° C.). Then, the reaction liquid was distilled off under reduced pressure to remove most of pyridine. 800 mL of water was added to the prepared reactant, transferred to a separatory funnel, and extracted with 400 mL of ethyl acetate (extraction times: 3 times). The ethyl acetate layers were combined and concentrated, and 156 g of the resulting residue and 300 g of acetic acid were added to a three-necked flask equipped with a thermometer, Dimroth and a stirring device, heated to reflux at 120° C. for 8 hours, and purified after the triphenylmethyl group was eliminated. Polyglycerol A was prepared. The hy...

Embodiment 2( Synthetic example 2

[0066] Hydroxyl value Purified polyglycerol B of 803 mgKOH / g, primary hydroxyl group ratio of 62.1%, and secondary hydroxyl group ratio of 37.9%. Then, 60 g of the prepared polyglycerol B, 180 g of the mixed fatty acids shown in Table 1, and 0.1 g of sodium hydroxide were added to a 300 mL four-necked flask, and the resulting water was removed at 250° C. under a nitrogen stream. The reaction of the obtained polyglycerol fatty acid ester B with a hydroxyl value of 18 mgKOH / g.

Embodiment 3( Synthetic example 3

[0068]Hydroxyl value Purified polyglycerol C with 790 mgKOH / g, a primary hydroxyl group ratio of 63.0%, and a secondary hydroxyl group ratio of 37.0%. Then, 64.8g of the prepared polyglycerol C, 175.2g of the mixed fatty acids shown in Table 1, 0.1g of sodium hydroxide were added to a 300mL four-necked flask, and the resulting water was removed at 250 ℃ to react to obtain polyglycerol fatty acid ester C with a hydroxyl value of 35 mgKOH / g.

Abstract

Disclosed is a crystal growth inhibitor for fats and oils, which contains a polyglycerin fatty acid ester having a hydroxyl number of not more than 100 mgKOH / g which is an esterification product of a fatty acid and a polyglycerin having a hydroxyl number of not more than 850 mgKOH / g and a primary hydroxyl group content of not less than 50% in the total hydroxy groups in the polyglycerin. When the crystal growth inhibitor for fats and oils is added into a fat or oil, crystal growth of the fat or oil can be suppressed, thereby improving storage stability of the fat or oil in refrigerators, cold regions and the like. Consequently, the crystal growth inhibitor for fats and oils is suitably used for liquid fats or oils such as cooking oils, for which transparency is an important factor.

Description

technical field [0001] The present invention relates to lipid crystal growth inhibitors. More specifically, it relates to a crystal growth inhibitor of liquid fats and oils at low temperatures, and an oil and fat composition containing the same. Background technique [0002] Generally, fats and oils such as rapeseed oil, rice bran oil, soybean oil, and cottonseed oil are liquid at room temperature. Since these liquid oils are stored at low temperatures such as in refrigerators or cold regions, wax components or high-melting triglycerides contained in the oil crystallize. As a result, there is a problem that the fluidity of the oil is lost, cloudiness or separation occurs, and the commercial value decreases. [0003] In addition, palm oil is now attracting attention in the oil industry, and its production volume is second only to soybean oil, occupying the world's second vegetable oil throne, and becoming an indispensable raw material for the oil industry. As liquid fats a...
