Abstract
Hydrodynamic cavitation (HC) is thought weaken the allergenicity of beer gluten proteins. However, the mechanism of action has not been thoroughly studied. In this study, an HC device was used to treat wheat gliadin and two specific celiac-toxic peptides, P1 and P2. FT-IR, MFS, HPLC, and CD were used to monitor the structural characteristics of gliadin and the two peptides. HC reduced the abundance of the coeliac toxic peptides P1 and P2 in solution and the contents of secondary structure β-turns and PPII, which are related to reduced allergen immunoreactivity. This meant that both the primary and secondary structures of P1 and P2 were affected by HC, leading to fewer allergic reactions. This study was focused on the impact of HC on the secondary structures of allergens produced from gluten raw materials, and it has positive implications for reducing product allergenicity.
期刊介绍：
The Journal of Food Science and Technology (JFST) is the official publication of the Association of Food Scientists and Technologists of India (AFSTI). This monthly publishes peer-reviewed research papers and reviews in all branches of science, technology, packaging and engineering of foods and food products. Special emphasis is given to fundamental and applied research findings that have potential for enhancing product quality, extend shelf life of fresh and processed food products and improve process efficiency. Critical reviews on new perspectives in food handling and processing, innovative and emerging technologies and trends and future research in food products and food industry byproducts are also welcome. The journal also publishes book reviews relevant to all aspects of food science, technology and engineering.
