Изобретение относитс  к способам оценки качества пищевого сырь  и, может быть использовано при селекции в м сном скотоводстве.The invention relates to methods for assessing the quality of food raw materials and can be used for breeding in livestock breeding.

Целью изобретени   вл етс  ускорение способа и снижение его трудоемкости .The aim of the invention is to accelerate the method and reduce its complexity.

Сущность способа заключаетс  в том, что измер ют коэффициенты отражени  м са на длинах волн 480-520 и 640-720 нм и вычисл ют интенсивность его окраски по следующей формулеThe essence of the method is that the reflection coefficients of the mea are measured at the wavelengths of 480-520 and 640-720 nm and the intensity of its color is calculated using the following formula

R, - 10 ftR, - 10 ft

A cylinder with a diameter of 50 mm and a height of 6 mm was cut out of a sample of beef fish. This cylinder was placed in the measuring unit of the SF-10 spectrophotometer and the reflection curve was removed in the O range of 400-700 nm (see drawing). Processing the curve showed that R |
