Outline of Final Research Achievements

Food-derived proteins and its hydrolysates are being used for beneficial application for cosmetic products such as moisturizers. In this study, we focused on hen’s eggs as a representative food derived-cosmetic material. In order to obtain information that contributes to the establishment of safety index, we have developed an LC-MS/MS method for simultaneous four egg white allergens quantification, such as ovomucoid, ovalbumin, ovotransferrin, and lysozyme. Using this method, we assessed the allergen levels in fresh and dried egg white and determined the degradation degree of ovalbumin in enzymatic hydrolysates derived from fresh and dried egg white, indicating the progress of the hydrolysis reaction.

Academic Significance and Societal Importance of the Research Achievements

鶏卵アレルゲンは複数種類存在するため、免疫学的手法に基づく従来の個別分析の手法では分析が煩雑であった。本研究では、質量分析計を用いて複数種類の鶏卵アレルゲンに対する同時定量を可能とした。また、本法を利用することで、従来の手法では分析困難とされていた鶏卵加水分解物中のアレルゲン定量が可能となり、その分解度の制御が可能となった。これらの客観的な情報を指標として活用することで、鶏卵タンパクおよびその加水分解物を使用した化粧品の安全性と品質の向上が期待される。
