Sea rice bran powder is a new type of instant food additive. Currently, its solubility is low, and its flavor is not pleasant. Superheated steam cooking is a promising treatment in cellulose-rich substances, which essentially improves quality. To gain better sea rice bran powder, physicochemical properties of sea rice bran were investigated using 100 °C, 110 °C, 120 °C, and 130 °C superheated steam treatments for 10, 20, 30, and 40 min. After the treatment, these samples were cooled down, dried, and milled to assess sea rice bran powder's product qualities. Profiles of odor, taste, aroma, and aliphatic acids were determined using e-nose, e-tongue, and gas chromatography-mass spectroscopy. Results revealed that superheated steam brought new profiles of odors and tastes for consumers. Superheated steam treatment was found to decrease swelling capacity. Methane (2,2,4,6,6-pentamethyl, heptane) was seen as a significant odor component, whereas umami and bitterness were considered considerable taste components. Superheated steam treatment retained higher content of aliphatic acids: saturated fatty acids 218-204 mg/100 g and unsaturated fatty acids 830-781 mg/100 g. This study discovered that superheated steam is suitable for processing rice bran as food ingredients; 100 °C-120 °C and 10-30 min could be suggested for suitable cooking sea rice bran.
海米糠粉是一种新型的即食食品添加剂。目前，其溶解度较低，且风味不佳。过热蒸汽烹饪是纤维素丰富物质的一种很有前途的处理方法，它从本质上改善了质量。为了获得更好的海米糠粉，使用 100°C、110°C、120°C 和 130°C 的过热蒸汽分别处理 10、20、30 和 40min，对海米糠的理化性质进行了研究。处理后，将这些样品冷却、干燥并研磨，以评估海米糠粉的产品质量。使用电子鼻、电子舌和气相色谱-质谱联用仪测定了气味、味道、香气和脂肪酸的轮廓。结果表明，过热蒸汽为消费者带来了新的气味和味道特征。过热蒸汽处理降低了膨胀能力。甲烷（2,2,4,6,6-五甲基庚烷）被视为重要的气味成分，而鲜味和苦味被认为是重要的味道成分。过热蒸汽处理保留了更高含量的脂肪酸：饱和脂肪酸 218-204mg/100g 和不饱和脂肪酸 830-781mg/100g。本研究发现，过热蒸汽适合作为食品原料加工米糠；100°C-120°C 和 10-30min 可能适合蒸煮海米糠。
