Sensegood spectrophotometer for color measurement and analysis in natural and color coated seeds

Published international research proves the dependency of seed quality and initial seedling growth on seed color. Color parameters b*, C*, L*, and H°, showed significant correlation with seed’s quality parameters. [1] Seed color affects light requirement during germination. [2] Study also mentions that the seed coat color variation relates to the seed yield parameters. [3] Color of a seed indicates its physiochemical properties and nutrition value.



It means that the seed producing firms have to develop a trust by ensuring quality seeds so farmers and producers get their returns when each seed grow into seedling. And as research cite; seed color is one of the most important parameter in determination of quality of the seed and healthy germination ahead. It becomes essential need for seed producers to regulate required seed color.

Significant effects of color on seed quality parameters is promoting crop researchers and seed producers for developing FIFRA (The Federal Insecticide, Fungicide, and Rodenticide Act) and similar other compliant seed coating colorants. Seed coating polymer is aqueous base, environment friendly, film forming stabilized carboxylated polymer. It is used extensively to coat seeds with additives such as pesticides, growth stimulants and other agro chemicals. The thin coating of polymer helps the additives to stay on seeds and to avoid dusting and pollution and also enhance appearance of the seed in good faith.

Sensegood spectrophotometer is an analytical color measurement instrument that is widely accepted in the industry and research fraternity. From raw material to final product, it comprehensively evaluates the color attributes of various samples, including solids, liquids, powders and pastes. Sample can be non homogeneous with different shape and size. Sensegood spectrophotometer has rotating sample platform with large viewing area (sensor’s field of view). It takes multiple measurements over number of rotations and generates average result representing the sample’s color. As a result, consistency can be maintained and quality standards can be met with less waste, time, and effort.
