Problems solved by technology

However, the difficulty of this method is that it is difficult to remove the additive
As a result, in particular, a method for efficiently fractionating and producing solid fats and oils mainly composed of SSS-type triglycerides with an iodine value of about 5 has not yet been established.

[0076]

[0077] Iodine value was determined using the A.O.C.S. test method (Official Method Cd 1-25). Specifically, 10 mL of cyclohexane was added and dissolved in 0.5 to 3 g of sample oil and fat, and then 25 mL of Wijs solution was added and left to stand in a dark place for 1 hour. Then, after adding 20 mL of 10 g / 100 mL potassium iodide solution and 100 mL of water to stop the reaction, titrate with 0.1 N sodium thiosulfate to obtain the amount of iodine added to fats and oils. The iodine value conversion method is based on the following formula.

[0078] Iodine value = (A-B) × F × 1.269 / C

[0079] A: In the above determination test, the amount of 0.1mol / L sodium thiosulfate standard solution used in the blank test without adding sample oil (ml)

[0080] B: the amount of 0.1mol / L sodium thiosulfate standard solution in the above-mentioned determination test (ml)

[0081] F: Correction coefficient of 0.1mol / L sodium thiosulfate (1.005 in this example)

[0082] C: Samp...

Embodiment 1

[0093] 450.0 g of the same palm kernel oil as in Comparative Example 1 was mixed with 50.0 g of myristic acid (manufactured by Wako Pure Chemical Industries, Ltd.), and heated at 60° C. for 1 hour in a constant temperature water bath at 60° C. to make the palm kernel oil and nutmeg The acid melts completely. The melted heating melt was put into a container made of polypropylene, and was left to stand in a constant temperature water bath at 20° C. for 12 hours to cool and solidify, thereby crystallizing the filter cake. Subsequent operations were performed in the same manner as in Comparative Example 1, and fatty acids were removed to obtain purified solid fats and oils and liquid fats and oils. The results are shown in Table 1.

Embodiment 2

[0095] 475.0 g of the same palm kernel oil as in Comparative Example 1 was mixed with 25.0 g of palmitic acid (manufactured by Wako Pure Chemical Industries, Ltd.), and heated at 60° C. for 1.5 hours in a constant temperature water bath at 60° C. to completely dissolve the palm kernel oil and palmitic acid. molten. The melted heating melt was put into a container made of polypropylene, and was left to stand in a constant temperature water bath at 21° C. for 12 hours to cool and solidify, thereby crystallizing the filter cake. Subsequent operations were performed in the same manner as in Comparative Example 1, and fatty acids were removed to obtain purified solid fats and oils and liquid fats and oils. The results are shown in Table 1.

Abstract

The purpose of the present invention is to provide a method for producing the solid oil or fat having a specified iodine value. Specifically provided is a method for producing the solid oil or fat, characterized by comprising the steps of: (1) mixing a lauric oil or fat with a fatty acid having 14 to 22 carbon atoms and then heating/melting the resultant mixture, wherein the amount of the fatty acid is 0.5 to 15 mass% relative to the total mass of the lauric oil or fat and the fatty acid; (2) cooling the heated/melted product produced by the above-mentioned heating/melting procedure to produce a crystallized product; (3) subjecting the crystallized product to a solid/liquid separation procedure to separate the crystallized product into a solid matter and a liquid matter; and (4) removing the fatty acid from the solid matter to produce the solid oil or fat.

Description

technical field [0001] The present invention relates to a method for producing solid oil with low iodine value by fractionation of glyceryl laurate oil, in particular to a method for fractionation of excellent solid oil as Cocoa Butter Substitute (CBS). The invention also relates to a method for fractionating glyceryl laurate oil into solid oil with low iodine value and liquid oil with high iodine value. Background technique [0002] Hard fat represented by cocoa butter is widely used in foods such as chocolate-based confectionery and bread, as well as pharmaceuticals and cosmetics. As these stearins, there are known: blended stearins mainly composed of symmetrical triglycerides (SUS, S is a saturated fatty acid, and U is an unsaturated fatty acid) having one unsaturated bond in the molecule; SSS-type triglycerides composed of saturated fatty acids as the main component of non-blended stearin, glyceryl laurate-based stearin, etc. [0003] Generally, laurin-based stearin ca...
