Industrial Application Field This invention relates to a method for processing potato starch. Conventional technology Potato starch has traditionally had good characteristics compared to other starches, such as larger particle size, lower gelatinization temperature, higher solubility, higher swelling degree, higher viscosity, and higher transparency. Utilizing its good characteristics, potato starch is mainly used as seafood and livestock paste products, eel feed, noodles, cooking materials, etc. However, depending on the use of potato starch, while the conventional good characteristics such as large particles and high viscosity are required, potato starch with a higher temperature at which the maximum viscosity is exhibited than conventional potato starch is required. It is being Examples include canned foods, retort foods that are processed at high temperatures such as casing kamaboko, and harusame, which requires a small amount of potato starch due to large dissolution loss during heating. Problems to be Solved by the Invention In order to solve the disadvantage of the conventional potato starch that the temperature at which the maximum viscosity is exhibited is relatively low, the present invention aims to increase the temperature at which the maximum viscosity of potato starch is exhibited and to improve heat resistance. The purpose of this is to increase the viscosity, reduce the decrease in viscosity, and suppress gelatinization by reducing the solubility. Means for Solving the Problems This invention reduces the concentration of potato starch to about 20-40% by weight.
A starch suspension with a pH of about 5 to 8 is heated at about 30°C in warm water at a temperature of about 40°C to about 55°C, which is lower than the gelatinization temperature of starch.
Stir or hold for minutes to 20 hours, then
This is a method for processing potato starch, which is characterized by dehydration and drying. The potato starch used in the processing method of this invention may be a potato starch suspension produced in the middle of the manufacturing process at a factory that produces potato starch, or dried commercially available potato starch may be resuspended in water. You may. Further, the maximum concentration of potato starch during processing in this invention is about 40% by weight for ease of handling, and the minimum concentration is about 20% by weight because if the concentration is too low, the production cost will increase. If the pH of the potato starch suspension of this invention is too low, hydrolysis of starch molecules will occur, and if the pH is too high, the physical properties of starch will change significantly, which is undesirable. Therefore, the pH of the potato starch suspension is about 5 to It is optimal to process the water between 8 and 8, and the pH of production water normally used is considered to be within this range, but if necessary, food-grade acids, alkalis, such as hydrochloric acid, sulfuric acid, acetic acid, It is recommended to use sodium hydroxide or potassium hydroxide. The processing temperature in the processing method of this invention is a temperature at which the potato starch particles do not gelatinize, specifically about 55°C or below, but if the processing temperature is below 40°C, processing must be carried out for a long time. The processing temperature should be approximately 40°C to 55°C since processing efficiency will be poor. The processing time in the processing method of this invention varies depending on the raw material potato starch and the physical properties of potato starch required by the user, but the processing time is about 30 minutes to 20 hours. The processing method of this invention may be either a continuous method or a batch method, and since it is important to quickly bring the potato starch suspension to a predetermined temperature for efficient processing, any suitable method may be used. It is advisable to use a preheating device. Function The potato starch processed by the potato starch processing method of the present invention can have a maximum viscosity several degrees higher than that of conventional potato starch, and can maintain high viscosity while maintaining high viscosity during the heating process. The decrease in viscosity can be reduced. Example 1 A starch suspension of 1 part potato starch and 4 parts water (weight ratio) was prepared at pH 6, and this starch suspension was placed in a container and stirred in an aqueous solution at 50°C for 5 hours. Dehydrate with a filter and dry with ventilation at 40℃ using a ventilation dryer. Processed using the processing method of Example 1,
Processing method and temperature of processing conditions in Example 1 (40°C,
The results of measuring the viscosity and other properties of unprocessed and processed potato starches with different stirring times (52.5°C, 55°C) and stirring times (1 hour, 20 hours) are as follows.

[Table] Measuring method Viscosity: Same method as the measuring method described in Example 1 above. Solubility: Weigh 125 mg to 250 mg of dry starch sample into a 50 ml graduated centrifuge tube, add water up to the 50 ml mark, close the stopper, and incubate at the specified temperature (70°C,
80℃, 90℃) in aqueous solution with occasional stirring.
Heat for a minute. After that, water was added up to the 50 ml mark, centrifuged at 3000 rpm for 15 minutes, the amount of starch in the supernatant was determined, and the solubility was calculated by dividing this by the weight of the collected sample. From the measurement results in Table 2, 1, it can be seen that by processing potato starch using the processing method of the present invention, the temperature at which the potato starch exhibits the highest viscosity becomes 8 to 10°C higher than that of unprocessed potato starch. Furthermore, as shown in Table 2-2 of the measurement results, by processing potato starch using the processing method of this invention, the solubility at any measurement temperature is 5.0% to 8.3% compared to unprocessed potato starch.
Since it becomes smaller, it can be seen that the solubility has become smaller, and it can also be seen that gelatinization has been suppressed. Example 3 Potato starch concentration was increased to 40% by weight and pH was 7.
The potato starch suspension was heated to 52.0℃ in advance,
This starch suspension is kept in the tank for 2 hours by flowing the starch suspension into the tank at a constant rate from the bottom of the tank where hot water for insulation is circulated outside, and flowing out at a constant rate from the top of the tank. The starch suspension that flows out is filtered, and the starch is dried in a ventilation dryer at 40°C. The results of measuring the viscosity and other properties of potato starch processed using the processing method of Example 3, processed using the processing method of Example 3 with the holding time changed to 1 hour, and unprocessed potato starch are as follows: It is as follows.

[Table] Table 3 of the measurement results shows that when potato starch is processed using the processing method of the present invention, the temperature at which the potato starch exhibits the highest viscosity is 12.5°C compared to unprocessed potato starch.
It can be seen that the heat resistance of the potato starch processed by the processing method of the present invention is improved by 14.5°C. It can also be seen that the longer the retention time, the more remarkable the degree is. Effects of the Invention By processing potato starch using the processing method of the present invention, it is possible to increase the temperature at which potato starch exhibits its maximum viscosity, and it is also possible to improve the heat resistance of the processed potato starch. Furthermore, the potato starch processed by the processing method of this invention can reduce the decrease in viscosity during the heating process, and can also reduce the solubility during heating, so the processed potato starch can be used in larger amounts as a raw material for products such as Harusame. It is possible to use.
