Versuchsvorschrift

Rutin (5 kg) was dispersed in 100 l of water (temperature: 55° C.). To this mixture were added 10 g of naringinase (Amano Enzyme, Inc., trade name: naringinase “Amano”, Japan) and each of the edible components (food additives, food ingredients) listed in Tables 1 and 2. The amount of each edible component added was adjusted that to attain the concentration in the mixture prepared as shown in Tables 1 and 2 (0.5 or 0.05 wt. %). The pH of the reaction mixture was 4.7. The reaction solution was left to stand 24 hours at 72° C., and then cooled to 30° C. The components precipitated by cooling were recovered by filtration. Solid filtrates were washed with water and then dried to obtain isoquercitrin.
