Description: TECHNICAL FIELD The present invention relates to a method for producing a carotene oil suspension under conditions where carotene is not decomposed. 2. Prior Art Since carotene is water-insoluble, it is known that, when used as a coloring material or the like, it is used in various applications in a state of being finely dispersed in oil. Although various dispersion methods are known, carotene has a low solubility in oil at room temperature and has a relatively high melting point, so that carotene is dissolved at a high temperature. For example, Japanese Patent Publication No. 35-8095 discloses a method in which carotenoids are dissolved in vegetable oil at 100 to 160 ° C., and Japanese Patent Publication No. 54-28858 discloses a method in which carotenoids are dissolved at 120 to 160 ° C. However, when carotene is dissolved in oil under high temperature conditions, there has been a problem that carotene decomposition proceeds with time. OBJECT OF THE INVENTION The present invention relates to a method for producing a carotene oil suspension by preventing carotene degradation. Constitution of the Invention The present invention dissolves oil and carotene in at least one solvent selected from hexane and acetone when finely dispersing carotene in oil, and then removes the solvent to remove carotene in oil. It is characterized by fine dispersion. Hereinafter, the present invention will be described in more detail. In the present invention, hexane or acetone or a mixed solvent of both is used as the solvent. Suitable oils include, for example, vegetable oils such as peanut oil, soybean oil, and cottonseed oil; synthetic oils such as medium-chain triseriglyceride; and animal oils such as squid oil and whale oil. The order of dissolution in the solvent may be to dissolve oil or carotene first,
Moreover, you may melt | dissolve both simultaneously. The amount of the solvent to be used is about 100 to 200 times the weight (weight) of carotene. The oil is preferably used in an amount (weight) of 1 to 20 times the amount of carotene. When carotene is dissolved in a solvent, it is preferably carried out at 60 ° C or lower, more preferably at 40 to 50 ° C, in order to sufficiently prevent decomposition. In the resulting carotene oil solvent solution, an antioxidant such as BHT, BHA, ascorbic acid fatty acid ester, and tocopherol; or an emulsifier such as sorbitan fatty acid ester, glycerin fatty acid ester, lecithin, sugar ester and derivatives thereof, benzoate, hydroxy Preservatives such as benzoate may be added. Next, the solvent is removed from the obtained carotene and oil solvent solution. Suitable methods for removing the solvent include, for example, a thin film evaporation method and a vacuum drying method. In addition, the solvent removal operation is performed at a low temperature, for example, to prevent the decomposition of carotene.
It is desirable to carry out at 60 ° C or less. Removal of the solvent results in an oil suspension of carotene. The particle size of carotene in oil is
10 μm or less, preferably 5 μm or less is appropriate. This fine dispersion can be obtained without performing any other operation other than the above operation. The obtained carotene oil suspension can be dried by adding gelatin, lactose, dextrin, gum arabic and the like. According to the present invention, the operation can be performed at a low temperature by dissolving the oil and carotene in a solvent selected from hexane or acetone and then removing the solvent. Therefore, carotene oil suspension can be produced by preventing carotene decomposition, which is a drawback of the conventional method of dissolving carotene in oil at high temperature. EXAMPLES Hereinafter, a carotene oil suspension was produced using three production methods, Method A (Example of the present invention), Method B, and Method C (both comparative examples), and the evaluation results are shown in Table 1 below. Indicated. Here, as the oil, those described in Table 1 were used in such an amount that the carotene concentration described in the table was obtained. The mixing was performed with a propeller type stirrer. Production method A method: Carotene and oil are added 40 to 50 times in a 200-fold (weight) solvent.
After dissolution at 0 ° C., the solvent is removed at 40 ° C. by thin film evaporation. Method B: Add carotene to oil and mix at 140-150 ° C. Method C: Carotene is added to the oil and mixed at 70 ° C.
