[0039] 2. Preparation of test solution
[0040] Make a uniform suspension (starch sample 1.25g / 100mL deionized water), take 4.0mL each of the suspension in two 50mL Erlenmeyer flasks, and add 3.35mL phosphoric acid-citric acid buffer solution to one flask Then as I liquid. Add 0.15 mL of 10M sodium hydroxide aqueous solution to another flask, heat at 37°C for 30 minutes to completely swell and disintegrate the starch particles, then add 1.5 mL of 1M phosphoric acid and 1.7 mL of 0.1M citric acid to make the liquid II. The two liquids were placed in a constant temperature bath at 37°C, and after the temperature was stabilized, 2.0 mL of the glucoamylase solution was added to each liquid, and while shaking it, the starch in each liquid was allowed to react with the glucoamylase for 120 minutes. After that, the enzyme was inactivated in a boiling bath, and 5.0 mL of Deproteinization A solution, 5.0 mL of B solution, and 1.0 mL of glycerin standard solution were added to each soluti...
Embodiment
[0066] Next, the present invention will be explained in more detail through examples.
[0067] First, a mixing example of coating materials is shown. The degree of alpha starch is obtained by the analysis method described in this specification in accordance with No. 51 of the Tariff Central Analysis Report.
[0068] Matching example 1
[0069] 10g iron oxide (α-Fe 2 O 3 Content 78%, particle size distribution; 18.0% above 150μm), 0.1g alpha starch (swelling degree 15.5mL / g, trade name; Amylox No.lA, alpha degree 98%, manufactured by Japan Corn Starch Co., Ltd.) to obtain this Invented coating material 1 for rice seeds.
[0070] Cooperation example 2
[0071] Add 20g iron oxide (α-Fe 2 O 3 Content 78%, particle size distribution; 18.0% above 150μm), 0.2g alpha starch (swelling degree 15.5mL / g, trade name; Amylox No.lA, alpha degree 98%, manufactured by Japan Corn Starch Co., Ltd.) to obtain the present invention The coating material for rice seeds2.
[0072] Cooperation example 3
[007...
manufacture example 1
[0099] First, a simple seed coating machine for coating a small amount of rice seeds is produced. Such as figure 1 As shown, a polyethylene cup 2 with a capacity of 200 mL is installed on the front end of the shaft 1 and inserted into the drive shaft of the blender 3 (THREE-ONE MOTOR, manufactured by Shinto Scientific Co., Ltd.), and the blender 3 is installed on the bracket 4 obliquely The elevation angle is 45 degrees, thus making a simple seed coating machine.
[0100] Water was added to a separately prepared polyethylene cup with a capacity of 200 mL, 20 g of dried rice seeds (Hinohikari) were added thereto, and the seeds were soaked at room temperature (10°C) for 10 minutes. The rice seeds were taken out of the polyethylene cup, and after using Kimwipes (registered trademark) to absorb the excess water on the surface, the rice seeds were put into the polyethylene cup installed in the simple seed coater made. Rotate the simple seed coating machine in the range of 130-140 rpm...
