Development of a sandwich enzyme-linked immunosorbent kit for reliable detection of milk allergens in processed food.

The inclusion of undeclared cow's milk proteins may cause health complications to milk-allergic consumers and is one of the leading cause of food recall in many countries all over the world. Therefore, to keep control on such incidences in processed products, we established a milk sandwich ELISA test kit by incorporating two polyclonal antibodies against milk proteins obtained from different species. Its analytical effectiveness in terms of sensitivity, specificity, accuracy, trueness, and precision were all analyzed.

A sensitive sandwich enzyme-linked immunosorbent assay (sELISA) targeted multiple wheat protein fractions for the detection of several cereal grains in processed foods.

Wheat allergy has become a global public health and food safety concern; however, there is no accessible cure for wheat allergy. The complete exclusion of wheat-containing foods and environmental exposure is the most efficient allergy management to avoid the adverse reactions, which can be severe and occasionally life threatening. Therefore, the assay for accurate detection of wheat residues is demanded urgently for appropriate labeling guidelines and consumer safety.

Development of a sensitive sandwich-ELISA assay for reliable detection of fish residues in foods.

A new sandwich-type Enzyme-Linked Immunosorbent Assay (ELISA) method was developed based on goat IgG as capturing antibody and rabbit IgG as detecting antibody targeting soluble antigenic fish proteins in foods as detection targets. The assay has provided a relatively lower limit of quantitation (LoQ) for fish proteins with LoQ 0.5 ng/ml and appears highly sensitive.

Whey allergens: Influence of nonthermal processing treatments and their detection methods.

Whey and its components are recognized as value-added ingredients in infant formulas, beverages, sports nutritious foods, and other food products. Whey offers opportunities for the food industrial sector to develop functional foods with potential health benefits due to its unique physiological and functional attributes. Despite all the above importance, the consumption of whey protein (WP) can trigger hypersensitive reactions and is a constant threat for sensitive individuals.

Extraction of total wheat (Triticum aestivum) protein fractions and cross-reactivity of wheat allergens with other cereals.

A one-step mild extraction of total wheat protein fractions was developed in this study, and the allergic cross-reactivity among dietary cereals were assessed by SDS-PAGE, western blotting, indirect ELISA, and inhibition ELISA using sera from 12 wheat allergic patients. The fractions of albumin, globulin, gliadin and glutenins in wheat flour can be obtained by a one-step extraction with NaCO-NaHCO (20 mM, pH 9.6, 0.

A review on food processing and preparation methods for altering fish allergenicity.

People eat many varieties of food to satiate their hunger. Among them, a few numbers of food cause overreaction of the body's immune system, and fish holds a permanent position on that list. Processing methods, including one treatment or a combination, can have different effects on the allergenic potential of food proteins.
