Abstract
Rice high in resistant starch (RS) showed great benefits in preventing diabetes. Red mold rice (RMR) is a traditionally functional food in China, preparing RMR with high-RS rice might produce a novel RMR with better nutrients and promote the utilization of high-RS rice in the food industry. R4 with the highest RS content was the most prone to be fermented by Monascus. After fermentation, the total starch and protein contents were significantly decreased, while the RS, lipid, free glucan, total free amino acids (FAAs), and γ-aminobutyric acid (GABA) contents were remarkably increased. Concurrently, the phenolic content and antioxidation activity were enhanced greatly. The individual phenolic acids such as ferulic acid showed significantly positive correlations with the antioxidant activity. Besides the abundant lipids, FAAs, GABA, and strong antioxidant capacity, fermented R4 had the highest ferulic acid content. This study provided alternatives for producing novel RMR and widened applications of high-RS rice in innovative functional foods.
期刊介绍：
The Journal of Cereal Science was established in 1983 to provide an International forum for the publication of original research papers of high standing covering all aspects of cereal science related to the functional and nutritional quality of cereal grains (true cereals - members of the Poaceae family and starchy pseudocereals - members of the Amaranthaceae, Chenopodiaceae and Polygonaceae families) and their products, in relation to the cereals used. The journal also publishes concise and critical review articles appraising the status and future directions of specific areas of cereal science and short communications that present news of important advances in research. The journal aims at topicality and at providing comprehensive coverage of progress in the field.
