The present invention relates to a method for producing a water-soluble biotin preparation, which comprises spray-drying an aqueous solution containing biotin, lactose, and ammonia. Biotin is generally used as a feed additive for livestock, farmed fish, etc. It is also used medicinally to prevent and treat skin diseases. Since biotin is sparingly soluble in water, it is not possible to adopt a method of adding biotin that achieves high homogeneity in feed by dissolving biotin in water and spraying it onto feed, which is extremely inconvenient in use. Furthermore, when urgently administering biotin to livestock, it is usually dissolved in drinking water or liquid feed, but this method of administration is not possible in the case of biotin because it is sparingly soluble in water. Furthermore, they have the disadvantage of poor absorption rate during administration, slow onset of effects, and insufficient bioavailability. Therefore, in order to overcome the above-mentioned inconveniences and drawbacks in use, we have intensively investigated various methods for increasing the solubility of biotin in water.As a result, we have found that simply mixing biotin and lactose does not increase the solubility of biotin. It was found that the solubility of biotin in water was significantly enhanced by spray drying an aqueous solution containing biotin, lactose, and ammonia. Since the preparation obtained by the method of the present invention is soluble in water, it can be used by dissolving it in drinking water or liquid feed, and biotin is uniformly dispersed and contained in each particle of lactose, and the particle size is small. Because the granules are small and spherical, they have excellent fluidity, making it easy to mix uniformly into feed.
Furthermore, since it has no hygroscopicity, it does not solidify due to moisture absorption, and it has been found that it is extremely effective in practice, and the present invention has been completed. The method of the invention is carried out by dissolving biotin, lactose and ammonia as described above and then spray drying this aqueous solution in a manner known per se. At this time, when only biotin is dissolved in an aqueous solution containing ammonia and then spray-dried, no increase in solubility in water is observed and the addition of lactose is necessary. The blending ratio of biotin and lactose is not particularly limited, but in actual products it is usually in the range of 1:40 to 1:100. On the other hand, it is desirable that biotin be completely dissolved in the solution to be spray-dried, and for this purpose it is necessary to add ammonia. The amount of ammonia added should be sufficient to dissolve biotin, usually 0.1 as a 28% ammonia aqueous solution.
The liquid property of the solution that is spray dried after adding %W/V or more is
It is convenient to adjust the pH to 5-9. The method of adding biotin, lactose, and ammonia is not particularly limited, but usually a method of adding lactose to an aqueous ammonia solution and then adding biotin, a method of adding a mixture of lactose and biotin to an aqueous ammonia solution, or a method of adding a mixture of lactose and biotin. A method is used in which ammonia is added after dispersing in water. As detailed above, according to the method of the present invention, poorly water-soluble biotin can be provided as a practically extremely effective water-soluble biotin preparation. The method of the present invention will be explained in detail below with reference to Examples. Example 1 Add 10 g of biotin and 490 g of lactose to 2000 ml of water containing 28% ammonia aqueous solution and 0.25% W/V and boil for 60~
Heat to 70℃ to dissolve. Spray this liquid using a mini spray dryer (Yamato Scientific Co., Ltd.)
Co., Ltd. under the following operating conditions, spherical particles with a particle size of 5 μm to 40 μm were obtained. Operating conditions Γ Chamber temperature: 130-140℃ Γ Chamber vacuum: 30mmH 2 O Γ Atomization pressure: 2.5Kg/cm 2The fluidity of this formulation is good and the critical specific humidity is 92
% and extremely low hygroscopicity. Next, Table 1 shows the results of comparison with reference examples regarding the enhancement of the water solubility of the biotin preparation obtained by the method of the present invention. Note that solubility was measured at room temperature, and biotin was quantified by high performance liquid chromatography. Reference Example 1 10 g of biotin and 490 g of lactose are weighed and mixed in a V-type mixer for 30 minutes to prepare a biotin preparation containing 2% W/W biotin. Reference example 2 Biotin 10g 28% ammonia aqueous solution 0.25%
It was added to 2000 ml of water containing W/V and heated to 60-70°C to dissolve, and then spray-dried under the same operating conditions as in Example 1. Reference example 3 Add 10g of biotin and 490% lactose to 2000ml of water and make 60~
Heat to 70°C and stir to obtain a uniformly dispersed suspension. This suspension was spray dried under the same operating conditions as in Example 1.
