New SENSIStrip PowerLine Tests for Crustaceans, Lupin, Ovalbumin and Sesame: Fast Results, No False Negatives

We are pleased to announce the launch of four new products in our allergen PowerLine test range:

• SENSIStrip Crustaceans PowerLine
• SENSIStrip Lupin PowerLine
• SENSIStrip Ovalbumin PowerLine
• SENSIStrip Sesame PowerLine

These new SENSIStrip PowerLine lateral flow tests deliver highly sensitive allergen detection with integrated hook-line technology to eliminate false-negative results.

Allergenic proteins and their impact

Crustaceans are among the most important food allergens, partly due to their cross-reactivity with house dust mites. The key allergenic protein is tropomyosin, which is present in all common crustacean species and accounts for around 20% of the total protein in cooked crustacean extracts.

Lupin is a protein-rich legume, with proteins accounting for approximately 35–45% of the seed. Several of these compounds are known allergens and may cross-react with soy and peanut allergens. Due to its valuable nutritional properties, lupin flour is increasingly used as a food ingredient, especially in dairy-free, vegetarian, and gluten-free products. As its use continues to grow, reliable detection of lupin residues is becoming increasingly important for food safety and allergen management.

Ovalbumin is a major egg white allergen, widely used in the food industry and as a fining agent in wine production. For egg-allergic individuals, even trace amounts can trigger allergic reactions, including severe anaphylaxis. Undeclared ingredients and cross-contamination therefore pose significant risks. As allergen labeling is required for wine in the European Union, sensitive detection methods are essential for the reliable identification of ovalbumin residues.

Sesame seeds are very rich in proteins and well-known food allergens. Due to its widespread use in food products, sesame poses a significant risk for allergic individuals. As cross-contamination during food production cannot always be avoided, highly sensitive detection tools are crucial to protect allergic consumers.

Given the significant risks these allergens pose, precise and sensitive allergen detection systems are essential to ensure consumer safety. Our SENSIStrip PowerLine lateral flow tests provide rapid and reliable allergen detection, featuring an integrated hook-line technology to prevent false negative results and to ensure maximum reliability.

Allergen PowerLine Tests: Technology Advantages

• Hook-Line Technology: Eliminates the risk of false-negative results from hook effect in highly contaminated samples
• Highly Sensitive Detection: High sensitivity and specificity
• Versatile Application: Suitable for food matrices, rinse water, and environmental swabs
• Rapid Testing: Only minutes of preparation and evaluation
• Convenience: 20 individual tests per kit
• Complete Test Solution: All necessary, ready-to-use materials included
• Obtain the most precise results: Results can be interpreted visually with the evaluation card provided in the kit. In addition, a quantitative evaluation in combination with our RapidScan ST5 lateral flow reader, is also possible and validated.

These highly sensitive tests are specifically designed for the detection of crustacean / lupin / ovalbumin / sesame residues in a variety of sample types, including food matrices, rinse water, and environmental swabs:

• SENSIStrip Crustaceans PowerLine Food matrix sensitivity: 50 ppb, Swabbing sensitivity: 0.13 ng/cm2, Rinse water sensitivity: 6.67 µg/L
• SENSIStrip Lupin PowerLine Food matrix sensitivity: 0.5 ppm, Swabbing sensitivity 1.33 ng/cm2, Rinse water sensitivity: 0.07 mg/L
• SENSIStrip Ovalbumin PowerLine Food matrix sensitivity: 100 ppb, Swabbing sensitivity: 1 ng/cm2, Rinse water sensitivity: 50 µg/L
• SENSIStrip Sesame PowerLine Food matrix sensitivity: 5 ppm, Swabbing sensitivity: 0.013 µg/cm2, Rinse water sensitivity: 0.67 mg/L
