The effects of the soaking and steaming steps in rice parboiling on color changes and the levels of reducing sugars in rice were studied. Brown rice was soaked to different moisture contents (MC, 15, 20, 25. and 30%). The L*, a*, b* color parameters of the Commission Internationale de L'Eclairage (CIE 1976) indicated that during soaking, red and yellow bran pigments diffused from the bran into the endosperm. The increase in brightness brought about by soaking rice was attributed to migration of rice compounds (e.g., lipids) from the inner to the outer bran layers (rice surface). The levels of reducing sugars in brown and milled soaked rice samples increased with increasing brown rice MC after soaking. The total color difference (Delta E) between parboiled and nonpar-boiled rice increased with increasing MC after soaking and depended on the intensity,l the steaming conditions as reflected in the degree of starch gelatinization, Parboiling affected yellowness more than redness in mildly steamed brown rice and most in intermediately steamed brown rice. Severe steaming of brown rice affected redness more than yellowness. All three parboilin,, conditions equally affected the yellow color more than the red color in milled rice, Linear regression analyses indicated that parboiling had a larger effect oil Delta E of milled parboiled rice than of brown parboiled rice. Furthermore, the linear relationship between the level of gelatinized starch and Delta E of the milled parboiled rice samples showed that both parameters are indicators for the degree of parboiling. Reducing sugars were formed and lost during steaming. suggesting Maillard reactions during steaming.
