                                A 9 kDa lipid transfer protein (LTP) was identified as a major protein on the surface of broccoli leaves as early as 1994. Yes, broccoli does contain LTP, a type of protein that is increasingly recognized as a significant food allergen, particularly in certain populations and geographical regions.
