Appearance of raw materials is determined visually, treating it with the naked eye or with a magnifying glass, the color of dry raw material – visual in daylight. Odor set organoleptically without first changing the state of raw materials, then rubbing it between your fingers or a mortar. To enhance the smell of raw material is moistened with water. Taste organoleptically evaluated in the dry raw materials or in its 10% aqueous broth (without swallowing). The taste of raw poisonous plants do not identify as as an opportunity to clean the pillows on the equipment for cleaning pads. Infection of raw granary pests determine with the naked eye or with a magnifying glass with an increase in the external examination in determining the fineness and content of impurities. If you find a raw granary pests determine the degree of infestation. For this sample material is placed on a sieve with an aperture of 0.5 mm and sieved.

In raw materials, through the past sieve, count the number of ticks. In the raw material, remaining on the sieve, count the number of moles, of larvae, pupae, and other living and dead pests. The number of insects and their larvae counted per 1 kg of raw material. Fineness – and one of the key indicators of quality raw materials. Need cleaning pads. Dry raw materials for packaging and shipping some frays, breaks down and loses its marketability.

The number of ground units in raw materials is established by sieving through a sieve with holes, indicated by the standard. Valid contaminants include parts of the plants that do not fit in the standard name of raw materials, such as leaves and stems of flowers, twigs and buds in the kidney, the presence of pieces of roots and rhizomes in the purified raw materials, etc. The composition of allowable impurities are also organic (parts of other plants) and minerals (sand, earth) impurities in the restoration. The number of allowable impurities is established for each type of raw material separately and depends on the botanical characteristics of raw materials, growing conditions, harvesting and processing, timing, etc. The composition of the collection organic impurities is checked for the absence of poisonous plants. If impurities are found in poisonous plants, the entire batch is rejected or re-sort.
