水溶性提取物是具有商业营养吸引力的植物饮料，涉及健康方面，如不含动物脂肪和高矿物质含量。本研究旨在比较整米、碎米及大豆水溶性萃取物之理化特性。分析（一式三份）为pH、可溶性固形物含量、水分、灰分、蛋白质、脂质、总碳水化合物、钙、镁、铜、锰、铁、锌和热值。碎米提取物中碳水化合物含量最高（3.17 g 100 g（-1））和灰分的最低值（0.58 g 100 g（-1）），蛋白质（0.73 g 100 g（-1）），脂质（0.41 g 100 g（-1）），和热值（17.28千卡100克（-1）），而全米提取物显示出最高的pH值（6.77）和中间值的钙（1.2 mg 100 g（-1））和镁（1.69 mg 100 g（-1））。大豆提取物中的矿物质、灰分、蛋白质、脂类和热值含量最高，分别为0.84 g/100 g（-1）、2.51 g/100 g（-1）、1.05 g/100 g（-1）和68.34 kcal/100 g（-1），碳水化合物含量最低，为2.62 g/100 g（-1）。尽管其营养价值较低，但与大豆提取物相比，全米和碎米提取物可以替代牛奶或大豆提取物，对于任何乳糖不耐受或大豆蛋白过敏的人来说。
Hydrosoluble extracts are vegetable drinks with a commercial nutritional appeal, concerning health aspects, like absence of animal fats and high minerals contents. This study aimed to compare the physical and chemical characteristics of whole rice, broken rice, and soybean hydrosoluble extracts. The analyses (in triplicate) were pH, soluble solids content, moisture, ashes, proteins, lipids, total carbohydrates, calcium, magnesium, cupper, manganese, iron, zinc, and caloric value. The broken rice extract presented the highest carbohydrates content (3.17 g 100 g(-1)) and the lowest value for ashes (0.58 g 100 g(-1)), proteins (0.73 g 100 g(-1)), lipids (0.41 g 100 g(-1)), and caloric value (17.28 kcal 100 g(-1)), while the whole rice extract showed the highest pH (6.77) and intermediate values for calcium (1.2 mg 100 g(-1)) and magnesium (1.69 mg 100 g(-1)). The soybean extract presented the highest contents of all minerals, ashes (0.84 g 100 g(-1)), proteins (2.51 g 100 g(-1)), lipids (1.05 g 100 g(-1)), and caloric value (68.34 kcal 100 g(-1)), but the lowest value for carbohydrates (2.62 g 100 g(-1)). Despite its lower nutritional value, when compared to the soybean extract, the whole and broken rice extracts can be viable alternatives for replacing milk or soybean extract, by people with any kind of lactose intolerance or soybean protein allergy.
