ORGANOLEPTIC EVALUATION - TOUCH

Touch (Evaluation by touching)

• Insert hand deep into a bag of grains, if you didn’t find any temperature difference between inside and outside the bag it means that grains are properly dried.
• Take a pinch of rice polishing, rice bran or deoiled rice bran and rub between fingers. If it is too coarse & rough, it indicates adulteration with paddy husk.
• Fish meal with more moisture level will be dark in colour, hot and will not break easily.
