In pulse milling technology:

• Statement (I) is correct: The CFTRI (Central Food Technological Research Institute, Mysuru) method of dal milling is an advanced dry milling process that completely eliminates the traditional use of edible oils (such as linseed or mustard oil) for seed coat loosening. Instead, it utilizes pre-conditioning through hot-air heating followed by controlled moisture tempering to weaken the gum bond between the seed coat and cotyledons.
• Statement (II) is incorrect: Traditionally, wet-milled dhal is acknowledged to have better culinary taste, flavor, and texture upon cooking due to fermentation during soaking, whereas dry-milled dhal has superior storage stability and higher milling recovery but is not considered superior in taste.

Analysis of Parboiling Effects on Rice Rancidity:

• Assertion (A) is False: During parboiling, steaming and soaking cause lipid migration into the endosperm and disrupt cellular oil bodies. Although parboiling inactivates lipolytic enzymes (preventing hydrolytic rancidity), parboiled rice and parboiled bran develop oxidative rancidity and off-odors much faster than raw milled rice during extended storage.
• Reason (R) is True: High processing temperatures during the parboiling hydrothermal treatment decompose and destruct heat-sensitive natural antioxidants (such as tocopherols, tocotrienols, and gamma-oryzanol) present in the bran and germ, removing natural oxidation protection.

Design Characteristics of a Continuous Screw Press (Expeller):

• Statement (A) is Correct: The volumetric compression ratio ($CR$) of a screw press is defined as the volume displaced per worm revolution at the feed opening divided by the volume displaced per revolution at the discharge choke:
  $$CR = \frac{V_{\text{feed}}}{V_{\text{discharge}}}$$
• Statements (B), (C), and (D): To exert progressively increasing mechanical pressure on the oilseed cake and express oil through the cage barrel bars, the flight pitch and channel depth decrease from the feed end to the discharge choke while the root shaft diameter increases. Consequently, the volume displaced per revolution at the feed end is considerably greater than at the discharge end ($V_{\text{feed}} \gt V_{\text{discharge}}$).
