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.
Extratos hidrossolúveis são bebidas de origem vegetal, que possuem apelo comercial nutricional, quanto aos aspectos de saúde, como ausência de gorduras animais e altos teores de minerais. O objetivo deste trabalho foi comparar as características físico-químicas de extratos hidrossolúveis de arroz integral, quirera de arroz e soja. As análises (em triplicata) foram: pH, teor de sólidos solúveis, umidade, cinzas, proteínas, lipídeos, carboidratos totais, cálcio, magnésio, cobre, manganês, ferro, zinco e valor energético. O extrato de quirera de arroz apresentou o maior teor de carboidratos (3,17 g 100 g-1) e o menor teor de cinzas (0,58 g 100 g-1), proteínas (0,73 g 100 g-1), lipídeos (0,41 g 100 g-1) e valor energético (17,28 kcal 100 g-1), enquanto o extrato de arroz integral apresentou o maior valor de pH (6,77) e valores intermediários de cálcio (1,2 mg 100 g-1) e magnésio (1,69 mg 100 g-1). O extrato de soja se destacou com maiores valores de todos os minerais, cinzas (0,84 g 100 g-1), proteínas (2,51 g 100 g-1), lipídeos (1,05 g 100 g
