PHOTOLUMINESCENT QUALITY CONTROL OF AGRICULTURAL PRODUCTS
(pp. 55-60)

Abstract. The possibilities of optical photoluminescent control of agricultural products (grain, vegetable feed, milk) are investigated. Methods and devices for monitoring the moisture content of seeds and concentrated feeds have been developed. Based on the measurement of the luminescence ratio when excited by radiation of 362 and 485 nm, a method for assessing the degree of ripeness of seeds of grain plants has been created. Using luminescent fluxes at excitation of 232, 362 and 424 nm, a method and a portable device (LUM VIM-1) for determining grain contamination with fusarium have been created. When milk sours, quantitative and qualitative changes in luminescent properties occur. To create a method for monitoring milk quality indicators during souring, the most informative is the use of excitation wavelengths of 385 nm and 442 nm, followed by registration of photoluminescence in the ranges 440…490 nm and 490…600 nm, respectively.

Keywords: optical spectral diagnostics, photoluminescence, seeds of grain plants, vegetable feed, milk.
