FIELD: food products. ^ SUBSTANCE: coffee composition contains hydroxyhydroquinone from 0 to 0.00005 wt %. High-performance liquid chromatography analysis showed that composition doesn't contain any essential peak at the limit if relative retention time from 0.54 to 0.61 relative to gallic acid, used as reference material. Coffee composition contains hydroxyhydroquinone from 0 to 0.001 wt %. Beverage package contains coffee composition with hydroxyhydroquinone from 0 to 0.00005 wt %. Beverage package contains coffee composition, high-performance liquid chromatography analysis showed that composition doesn't contain any essential peak at the limit if relative retention time from 0.54 to 0.61 relative to gallic acid, used as reference material. Coffee composition preparation method includes fried coffee beans processing with activated charcoal. Activated charcoal is produced by activation using zink chloride or by activation using water steam. Production method of instant coffee composition consists of fried coffee beans processing with absorbent carbon and spray dehydration or dehydrofrosting of the coffee composition. ^ EFFECT: coffee composition doesn't produce hydrogen peroxide in the body even when it is used for a long time. ^ 7 cl, 8 dwg, 12 ex |
