The present invention relates to a quality improver for thiokolate.
In detail, fatty acids with 12 to 22 carbon atoms and a degree of polymerization of 2
This invention relates to the use of polyglycerin fatty acid esters having a hydroxyl value of 200 or less among polyglycerin fatty acid esters consisting of polyglycerin and polyglycerin of 15 to 15 as blooming inhibitors for thiokolate. Chiyokolate is generally produced by mixing bitter chiyoko, powdered sugar, cocoa butter, powdered milk, etc., pulverizing the mixture, followed by tempering and cooling. The quality of thiyocolate is greatly affected by the raw materials and various conditions in the manufacturing process.In particular, the phenomenon of blooming, which causes the surface to become grayish white during storage, can cause the product to lose its commercial value. This requires caution. Therefore, conventionally lecithin was added to prevent blooming, but
When lecithin is added, if there is an inappropriate temperature drop or overtempering during the manufacturing process of thiokolate, it will increase the viscosity, making it difficult to perform the work properly and making it difficult to properly crystallize the fat. It can also cause blooming. Additionally, attempts have been made to prevent blooming by adding monoglycerides, sorbitan esters, sugar esters, etc., but these methods are not sufficiently effective. Therefore, the inventors of the present invention came up with the idea that in order to prevent the blooming of thiyocolate, it would be sufficient to finely precipitate the fat crystals in thiyocolate and increase its affinity with other raw materials. As a result of extensive research into oil-soluble surfactants that are thought to have the following properties, we have found the optimal surfactant and completed the present invention. That is, the present invention provides fatty acids having 12 to 22 carbon atoms,
This invention relates to a quality improver for thiokolate, which uses a polyglycerin fatty acid ester having a hydroxyl value of 200 or less among polyglycerin fatty acid esters comprising polyglycerin having a degree of polymerization of 2 to 15. When used, one or more of the above polyglycerol fatty acid esters may be mixed by heating and dissolving or the like. Moreover, the quality improver of the present invention may be used in combination with other additives for thiokolate, mixed with various raw materials for thiokolate, or used alone, and is not particularly limited. The present invention will be explained in detail below. The method for producing polyglycerin fatty acid ester according to the present invention involves condensing a fatty acid having 12 to 22 carbon atoms with glycerin under high temperature conditions in an inert gas atmosphere to obtain a degree of polymerization of 2 to 15. It is obtained by adding a catalyst to polyglycerin and esterifying it by a conventional method. Fatty acid is 1
Either a species or a mixture of two or more species may be used. Further, the polyglycerin may be either a reaction product or a product purified by treatment such as distillation, activated carbon treatment, or ion exchange resin treatment after the reaction. In the case of a polyglycerin fatty acid ester having a fatty acid carbon number of 11 or less, it is not preferable because the melting point of the fat becomes too low when added to thiocholate.
Furthermore, polyglycerin fatty acid esters having a fatty acid carbon number of 23 or more are not preferable because their melting point is too high, which deteriorates the texture of thiocholate. Moreover, polyglycerin having a degree of polymerization of 16 or more is not practical because the viscosity of the raw material itself is too high, making the ester reaction extremely difficult. Moreover, if the hydroxyl value of the ester is 200 or more, the viscosity increases when added to thiokolate, making production difficult, which is not preferable. Hereinafter, the present invention will be specifically explained with reference to Examples. Example 1 Thiyocolate was prepared using the formulation and manufacturing method shown below. Prescription Bitter Chiyoco 40 parts Powdered sugar 48 parts Cocoa butter 12 parts To the above recipe, 0.5 part of hexaglycerin pentastearate (hydroxyl value = 90) was added as a quality improver, and Chiyocolate was prepared by the method shown below. All raw materials were heated and mixed and further atomized.
After gradually cooling the product temperature from 40°C to 25°C, it was left at 27°C for 1 hour and poured into a mold. It was further left at 20°C for one week. Chiyocolate was obtained which was smooth and had a good texture. Example 2 Thiyocolate was prepared in the same manner as in Example 1 using triglycerol tetrapalmitate (hydroxyl value = 30) as a quality improver. Chiyocolate was obtained which was smooth and had a good texture. Example 3 Using the same method as Example 1, hexaglycerin tetrabehenate (hydroxyl value = 180) was used as a quality improver.
Chiyokolate was created using Chiyocolate was obtained which was smooth and had a good texture. Comparative Example 1 Tiyokolate was prepared in the same manner as in Example 1 using 0.5 part of soybean lecithin. Thickening was observed upon cooling, but the thiokolate had a good texture. Comparative Example 2 Thyokolate was prepared in the same manner as in Example 1 using 0.5 part of hexaglycerol tristearate (hydroxyl value = 220). Thickening was observed upon cooling, and the thiokolate also had a hard texture. Comparative Example 3 Tiyokolate was prepared in the same manner as in Example 1 using 0.3 parts of soybean lecithin and 0.3 parts of Shugar ester (HLB=3). Chiyocolate with a rough appearance was obtained. The occurrence of blooming was measured for the thiyocolate obtained in Examples 1 to 3 and Comparative Examples 1 to 3. The test was carried out after placing the sample in a thermostat at 20℃ for 12 hours.
The experiment was carried out by placing the seeds in a thermostat at 30°C for 12 hours, and then moving the thermostat alternately to 20°C and 30°C, to see how many times blooming occurred. The results are shown in Table-1.
