Aprofood provides laboratory analysis services to accurately measure the content, composition, and characteristics of carbohydrates in food, delivering critical data for nutrition labeling, quality control, and functional research.
Carbohydrates in Food Products
Carbohydrates occur naturally in various types of foods such as grains, fruits, vegetables, dairy products, etc. They are also important nutrients in processed foods and beverages. Carbohydrates vary significantly in different types of products, taking common foods as an example:
- Grains: Starch-based, with a small amount of dietary fiber (the outer skin part).
- Fruits: Rich in fructose, glucose, sucrose, and pectin.
- Vegetables: Contain a small amount of starch and a large amount of dietary fiber.
- Legumes: Rich in oligosaccharides and dietary fiber.
- Starchy Tubers: e.g., potatoes, sweet potatoes, both starch and resistant starch.
- Processed Foods: e.g., candies, beverages often add refined sugar (sucrose, fructose syrup, etc.).
Our Service
With advanced technologies including high-performance liquid chromatography (HPLC), enzymatic hydrolysis, and Near-Infrared Spectroscopy, Aprofood offers the following key testing services for various food and beverage samples to meet diverse client needs:
Routine Carbohydrate Testing
Our testing services cover all basic carbohydrates in food, including monosaccharides, disaccharides, oligosaccharides, and polysaccharides. We provide both qualitative and quantitative analysis of specific sugars such as fructose, glucose, sucrose, lactose, sugar alcohols, and starch to meet nutritional labeling requirements.
Dietary Fibre Testing
Using the latest AOAC methods, we analyze food products for total dietary fiber, soluble dietary fiber (e.g., pectin), insoluble dietary fiber (e.g., lignin), dietary fiber subfractions (e.g., dextrins), and resistant starch.
Beta-Glucan Testing
We utilize HPLC, high-performance gel permeation chromatography (HPGPC), and scanning electron microscopy (SEM) to determine β-glucan content, analyze molecular weight distribution, evaluate solubility, and characterize structural-functional properties.
Glucose Metabolism Testing
Using HPLC coupled with ELSD detection, we efficiently and accurately quantify dynamic changes in carbohydrate metabolites. Complementing this, Aprofood offers biochemical assays for comprehensive sugar metabolism analysis to meet diverse analytical needs.
Special Carbohydrate Testing
Characterization of hydrocolloids in food products (e.g., xanthan gum, guar gum). Quantitative testing and structural analysis of oligosaccharides, inulin, and related compounds, including the identification of fructooligosaccharides (FOS), kestose, and nystose, as well as determination of average chain length or degree of polymerization (DP) for galactooligosaccharides (GOS).
Frequently Asked Questions (FAQs)
Q1: How much sample is required for testing?
A1: Typically, 50-100 g of solid samples or 50-100 mL of liquid samples are required, with the exact amount depending on the food matrix and specific test parameters.
Q2: What are the methods and detection limits for the assays requested?
A2: We strive to ensure that all analytical methods and detection limits comply with the latest testing standards and certifications. Should you have any questions regarding detection limits or quantification limits, please feel free to contact us.
Q3: What does the test report include?
A3: The report provides detailed content of specific carbohydrate concentrations, testing methodologies, referenced standards, along with professional interpretation.
