Casein Testing Solutions 
for Lab and On-Site Detection

Casein refers to a family of proteins commonly found in milk, with approximately 80% of bovine milk proteins being caseins. Composed of α-, β-, and κ-caseins, this protein fraction is the primary component in cheese and is frequently used as a food additive.

As heat-stable allergens, caseins pose a significant risk for some individuals. Bovine milk is a particularly common allergenic food ingredient, especially for children. As a result, many countries around the world mandate the labeling of casein or milk in their products.

While there are no legal threshold limits for casein, food manufacturers are strongly encouraged to test for even the lowest concentrations of casein to protect allergic individuals and avoid allergen-related recalls.
 

Fast and Highly Sensitive Casein Analysis Solutions

At Romer Labs, we offer a comprehensive range of solutions for casein detection, consisting of test kits and analytical services. Our casein test kit portfolio features quantitative ELISA tests and qualitative lateral flow devices (LFDs) that are specifically designed to detect casein proteins in environmental samples, rinse waters, and liquid and solid foodstuffs.

Fast and Reliable Test Kits for Casein Detection

Food allergens present a persistent challenge for individuals with allergies, making it crucial for food producers to accurately detect potential allergen contamination. Employing reliable test kits ensures the safety of consumers and compliance with regulatory standards.

Romer Labs provides a comprehensive portfolio of casein test kits designed for both qualitative (AgraStrip®) and quantitative (AgraQuant®) analyses of food allergens. These versatile tests cater to various applications, covering all phases of the food production process:

  • Testing of raw materials and finished food samples
  • Analysis of rinse waters (integral to cleaning validation)
  • Detection of allergens in environmental swab samples

Our casein test kits are designed for seamless integration into routine analyses as part of an allergen management plan, aligning with HACCP principles. The user-friendly test format ensures a streamlined workflow for both on-site and laboratory settings.
 

Detecting Fining Agents in Wine

Casein is an organic compound frequently used as a fining agent in winemaking. During the fining process, casein is added to bind to suspended particles, which then precipitate from the wine.

For wine samples, Romer Labs provides the validated AgraQuant® Casein ELISA and the AgraStrip® Casein LFD, both featuring a special wine extraction buffer specifically developed for wine analysis.
 

Legislative Compliance

In light of global regulations concerning food allergens (e.g., Regulation (EU) No 1169/2011; U.S. FDA – FALCPA 2004), it is imperative to properly label food products. Romer Labs' test kits support producers in fulfilling legal requirements, guaranteeing the safety and compliance of their products.

LFD - AgraStrip® Pro Allergen Test Kits

AgraStrip® Pro Allergen Test Kits represent a user-friendly, rapid solution for on-site allergen detection. These state-of-the-art lateral flow devices (LFD) deliver accurate results in just 11 minutes, including extraction time, making them an ideal choice for fast-paced environments.

Our AgraStrip® LFDs employ a cutting-edge qualitative strip test method that harnesses the power of specific antibodies, labeled with colloidal gold, to generate a visually discernible color development in both test and control zones. This innovative approach enables rapid analysis of a broad spectrum of food and environmental samples, ensuring the utmost safety and quality for your consumers.

The test kits come complete with strips, antibody-coated incubation vials, extraction tubes, an extraction buffer, surface swabs and additional accessories.
