In the dal milling industry, conditioning of the pulses is done to soften the outer layer, making it easier to dehull. The conditioning process involves using a combination of oil, water, and red earth to achieve the desired effect.
- Oil: While oil is sometimes used in the processing of pulses, it is not the only conditioning agent.
- Water: Water is essential for conditioning, but it works best when combined with other agents like oil and red earth.
- Red earth: Red earth, when used in combination with water and oil, helps in conditioning the pulses by softening their outer skin, which facilitates easier dehulling.
- Oil, water and red earth: Correct! This combination is the traditional and most effective method for conditioning pulses in the dal milling industry.
Thus, the correct answer is (4) Oil, water and red earth.
