    Rice flour based batter (RFBB) formulations were developed for deep-fat fried chicken nugget application. Ten combinations of the waxy rice (Rice Division6, RD6), low apparent amylose content (AAC) (Khao Dawk Mali105, KDML105) and high AAC rice (Rice Division31, RD31) were prepared according to the ten-point augmented simplex centroid mixture design. The AAC of RFBB samples ranged from 5.93 to 29.46% and contained less than 1�ppm of gluten content. After mixing rice flour (RF) with water at the ratio of 1:1.3, the decreased of apparent viscosities was found. Result showed that wheat flour based batter (WFBB) had higher wet pick-up (51.97%) than unblended RFBB (29.05�44.82%). However, the wet pick-up value was improved upon mixing three types of RF at various ratios. The RFBB formulas which contained high amount of dry-milled RD31 flour were more lightness and redness than others. These results suggested that the combination of RD6:KDML105:RD31 at the ratio of 16.7:16.7:66.7 provided the desirable RFBB as it contained similar AAC to WFBB. In addition, the coated chicken nugget with this sample tended to retain moisture content in both crust and core regions, and reduce oil content due to better oil resistance of RF than wheat flour. � 2019, Association of Food Scientists & Technologists (India).

    Improvement of parboiled brown rice properties using pre-germination process

    Importance of the work: Germination and parboiling were employed to improve the parboiled pre-germinated brown rice production. Objectives: To improve parboiled brown rice properties using a pre-germination process. Materials & Methods: Pre-germinated brown rice (PGBR) samples were prepared from paddy of Thai rice cultivars: Chai Nat1 (CNT1), Riceberry (RB) and Sun-Pah-Twang1 (SPT1). All samples were soaked in water at 30 ¡C for 12 hr and then incubated at 30 ¡C for 32Ð38 hr. Subsequently, all PGBR samples were parboiled under mild (100 ¡C, 10 min, 0 bar) and severe conditions (120 ¡C, 10 min, 1.05 bar) for comparison, before being dried until the moisture content was less than 12%. Later, all samples were analyzed for their physical, chemical and physicochemical properties. Results: Increased head rice yield and decreased yellowness were significantly affected by severe parboiling, while mild parboiling increased the redness of PPGBR from CNT1and SPT1. Both conditions of parboiling increased the crude protein (9.27Ð10.70%) and lipid (3.69Ð4.64%) contents but decreased the total starch content (80.78Ð81.98%). The alkali spreading score of CNT1 was 5 points (gelatinization temperature (GT) at 70Ð74 ¡C), while both RB and SPT1 had scores of 6 points (GT at 65Ð69 ¡C) under mild and severe parboiling, respectively. All three Thai rice cultivars showed a V-type X-ray diffraction pattern. Scanning electron micrographs confirmed gelatinization of the PPGBR for all three Thai rice cultivars with parboiling. Texture analysis revealed that cooked PPGBR had a lower hardness than cooked PBR for all three Thai rice cultivars. Main finding: Combined severe parboiling with germination improved the PPGBR quality of all rice cultivars. Copyright © 2021.
