Tóm tắt

Vị mặn là một thuộc tính cảm giác quan trọng trong nhiều loại thực phẩm, kích thích sự thèm ăn. Tuy nhiên, chế độ ăn nhiều muối mang lại nhiều rủi ro cho sức khỏe, do đó cần khám phá các lựa chọn thay thế có vị mặn để giải quyết vấn đề này. Các chất giảm muối có thể tạo ra những mùi vị mới trong thực phẩm. Do đó, nghiên cứu cần tập trung vào việc phát triển một chất mới, có thể thay thế muối mà không làm ảnh hưởng đến hương vị của thực phẩm. Thông thường, một số chiết xuất men có vị mặn và có thể được sử dụng để thay thế muối trong thực phẩm mà không tạo ra mùi vị bổ sung nào. Trong nghiên cứu này, chúng tôi đã phân lập các peptide mặn từ FA31 (Men Angel) bằng phương pháp siêu lọc, sắc ký thẩm thấu gel, sắc ký lỏng chuẩn bị (pre-HPLC), kết hợp với đánh giá cảm quan, và chuỗi peptide đã được xác định bằng ESI-Q-TOF LC/MS là Asp-Asp, Glu-Asp, Asp-Asp-Asp, Ser-Pro-Glu, và Phe-Ile.
