ASTM E2965 Detection of Milk Proteins in Food Matrices
The detection and quantification of milk proteins in food matrices is crucial for several reasons, including compliance with allergen labeling regulations and ensuring product safety. The standard test method ASTM E2965-19 provides a robust framework for identifying the presence of casein and whey proteins, which are the primary components of milk.
This service uses advanced immunoassay technology to target these specific proteins. Casein is a major protein in cow's milk, accounting for about 80% of the total milk protein content, while whey proteins make up the remaining 20%. The test method involves extracting these proteins from various food samples and detecting them using an enzyme-linked immunosorbent assay (ELISA).
The procedure outlined in ASTM E2965-19 specifies detailed sample preparation steps to ensure accurate results. This includes homogenizing the food matrix, filtering it through a fine mesh sieve, and then extracting the proteins into a suitable buffer solution. The extracted proteins are then subjected to an immunoassay where antibodies specific to casein and whey proteins bind to their respective targets.
Once bound, the concentration of these proteins is quantified by measuring the absorbance at 450 nm using a microplate reader. This allows for precise determination of the milk protein content in parts per million (ppm). The method's sensitivity enables detection down to levels as low as 1 ppm, making it suitable for both high and low-risk food products.
The ASTM E2965-19 standard is widely recognized for its accuracy and reliability. Compliance with this method ensures that food manufacturers can confidently label their products according to allergen regulations. This service not only helps in detecting the presence of milk proteins but also aids in tracking down potential sources of contamination, thereby enhancing product safety.
The service provided here is tailored to meet the needs of various stakeholders within the food industry, including quality managers, compliance officers, R&D engineers, and procurement teams. By leveraging ASTM E2965-19, these professionals can ensure that their products are compliant with international standards and regulations.
- Casein: The most abundant milk protein, accounting for about 80% of the total milk proteins in cow's milk.
- Whey Proteins: These make up the remaining 20% and include several important proteins like beta-lactoglobulin and alpha-lactalbumin.
Benefits
The ASTM E2965-19 method offers numerous benefits to food manufacturers, quality assurance teams, and regulatory bodies. One of the primary advantages is its ability to detect allergens accurately and reliably, which is essential for preventing allergic reactions in consumers with milk allergies.
