Joy JM, Lowery RP, Wilson JM, Purpura M, De Souza EO, Wilson SM, Kalman DS, Dudeck JE, Jäger R. The effects of 8 weeks of whey or rice protein supplementation on body composition and exercise performance. Nutr J. 2013 Jun 20;12:86. doi: 10.1186/1475-2891-12-86.

Abstract.  Therefore, the purpose of the study was to determine if the post-exercise consumption of rice protein isolate could increase recovery and elicit adequate changes in body composition compared to equally dosed whey protein isolate if given in large, isocaloric doses.

Kumagai T, Kawamura H, Fuse T, Watanabe T, Saito Y, Masumura T, Watanabe R, Kadowaki M. Production of rice protein by alkaline extraction improves its digestibility. J Nutr Sci Vitaminol (Tokyo). 2006 Dec;52(6):467-72. doi: 10.3177/jnsv.52.467.

Abstract.  A simple method to process rice protein and improve its digestibility was tested from the viewpoint of its application to food manufacturing.

Shih FF. An update on the processing of high-protein rice products. Nahrung. 2003 Dec;47(6):420-4. doi: 10.1002/food.200390093.

Abstract. This report provides an update on the processing of these sources for rice proteins. Methods of protein processing are highlighted including the traditional alkaline extraction, enzyme-assisted extraction, and the novel uses of physical treatment prior to water extraction. Also discussed are effects of processing on the functional and nutritional properties of rice protein.

Liu K, Zheng J, Chen F. Effect of domestic cooking on rice protein digestibility. Food Sci Nutr. 2019 Jan 24;7(2):608-616. doi: 10.1002/fsn3.884.

Abstract. The effects of washing, soaking, and common domestic cooking methods (normal cooking, high-pressure cooking, and microwave cooking) on protein content, in vitro protein digestibility, and amino acid composition of japonica and indica rice were investigated.

Koo WW, Lasekan JB. Rice protein-based infant formula: current status and future development. Minerva Pediatr. 2007 Feb;59(1):35-41.

Abstract. Rice is the world's leading staple cereal food and is the major source of protein for many parts of the world. Rice is among the first solid foods fed to infants in many cultures, in part because of its hypoallergenicity from lack of gluten. Nutritional quality of rice protein compares favorably with other cereal proteins including wheat, oat and barley.

Lu X, Ma R, Qiu H, Sun C, Tian Y. Mechanism of effect of endogenous/exogenous rice protein and its hydrolysates on rice starch digestibility. Int J Biol Macromol. 2021 Dec 15;193(Pt A):311-318. doi: 10.1016/j.ijbiomac.2021.10.140.

Abstract. The role of endogenous/exogenous rice protein and its hydrolysates in the enzymatic hydrolysis resistance of rice starch was investigated.

Dupont C, Bocquet A, Tomé D, Bernard M, Campeotto F, Dumond P, Essex A, Frelut ML, Guénard-Bilbault L, Lack G, Linglart A, Payot F, Taieb A, Kalach N. Hydrolyzed Rice Protein-Based Formulas, a Vegetal Alternative in Cow's Milk Allergy. Nutrients. 2020 Aug 31;12(9):2654. doi: 10.3390/nu12092654.

Abstract. This paper aims towards a better understanding of hydrolyzed rice protein formulas (HRPF), of the characteristics of rice proteins, their appropriateness to feeding cow’s milk protein allergy children, their suitability to restore normal growth, and their potential interaction with the acquisition of cow’s milk protein tolerance.

Likittrakulwong W, Poolprasert P, Srikaeo K. Effects of extraction methods on protein properties obtained from paddy rice and germinated paddy rice. PeerJ. 2021 May 4;9:e11365. doi: 10.7717/peerj.11365.

Abstract. Rice protein has attracted considerable attention recently due to its physiological effects. This study extracted the proteins from paddy rice (PR) and germinated paddy rice (GPR) using three methods i.e., alkaline, sodium dodecyl sulfate (SDS) reagent and enzymatic extractions.
