Nutritive Index Test Service
Food nutritive index is the indication of total nutrition level of foods. Many countries have listed food nutritive index test as an important test item for food as it provides direct and fundamental food composition information for public reference. Creative BioMart provides detailed food nutritive index test service in strict accordance with the Official Analytical Chemists (AOAC) requirements and the National Standard Method (GB).
Nutrition components mainly include sugar, lipids, proteins, vitamins, inorganic salt, fiber and water. They enter human body together with oxygen and are transformed into substances composing the human body and energy that sustains life activity.
Water influences the state, sensory property and spoilage of food. Test of water in food can help to determine food quality and reveal adulteration. Protein content and decomposition product can directly affect the smell, color and taste of food. Protein content measurement is an important indicator of the food nutritive value. Food fat is composed of glycerol and fatty acid. Fatty acid can be subdivided into saturated fatty acid, monounsaturated fatty acid and polyunsaturated fatty acid. Fat can constitute vital physiological substances, sustain body temperature, cushion outside pressure and provide essential fatty acid. Excessive fat absorption can induce various diseases, so food fat content measurement can be guidance for healthy diet. Carbohydrate is the generic terms of monosaccharides, oligosaccharides and polysaccharides, including glucose, sucrose, fructose, lactose and so on. The major function of carbohydrate is to provide energy. Among carbohydrate, fiber is drawing more attention due to its unique function in health maintenance and disease prevention. Our test on food carbohydrate can give you intuitive understanding of food healthy degree. Vitamin is a group of low-molecular-weight natural compounds sustaining normal physiological functions and specific metabolic reactions. Our food vitamin test can help you evaluate food nutritive value and finally adjust nutrient intake structure.
Creative BioMart provides various methods to test different nutrients, including HPLC, GC, LC, GC-MS/MS, LC-MS/MS, amino acid analyzer, moisture analyzer, etc.
