USDA Laboratory Protocol Starch Profiling in Processed Foods
The USDA Laboratory Protocol for starch profiling in processed foods is a comprehensive analytical method designed to determine the types and amounts of starch present within various food products. This protocol is essential for ensuring the accurate assessment and quality control of processed food items, especially those containing carbohydrates or fibers as key ingredients.
Starch plays a crucial role in many processed food products due to its functional properties such as gelling, thickening, textural stability, and binding capabilities. Understanding starch composition helps manufacturers optimize recipes for improved sensory characteristics while also ensuring compliance with regulatory standards.
The USDA protocol involves several steps including sample preparation where raw samples are ground into fine powders before extraction using appropriate solvents like ethanol or water. After extraction, the resulting slurry is analyzed via high-performance liquid chromatography (HPLC) coupled with refractive index detection to quantify individual components of starch.
Importantly, this service provides detailed information about the types and levels of amylose and amylopectin present in the sample which are key indicators for determining overall quality. Additionally, it identifies any additional complex carbohydrates or sugars that may be present alongside simple sugars like glucose and fructose.
This comprehensive approach allows us to not only meet but exceed USDA standards by offering accurate results that reflect the true nature of starches within processed foods.
Scope and Methodology
The scope of this service includes detailed analysis of carbohydrates present in various types of processed food products. Our laboratory adheres strictly to USDA guidelines when conducting starch profiling tests ensuring reliable data that can be used for quality assurance purposes.
- Sampling: Samples are collected from representative locations within the production facility or directly from retail outlets depending on client requirements.
- Preparation: Collected samples undergo thorough cleaning followed by drying and grinding into fine powders suitable for further processing steps.
- Extraction: Extracted starches are then subjected to HPLC analysis using specific reagents designed to separate different components based on their molecular weight distribution.
- Data Analysis: Results from the chromatograms are interpreted to provide insights regarding the presence and quantity of various types of starch molecules including amylose, amylopectin, dextrins, etc.
The methodology employed by our laboratory ensures consistency with international standards such as ISO 15263 which provides guidelines for determining total dietary fiber in foods. By adhering to these protocols we ensure that every test conducted meets industry best practices and regulatory requirements.
Why Choose This Test
