Generally speaking, the research of physiological transgene shows (the latest information I saw is the data in the annual report in March 2007, which should be the latest, hehe) that the larger the molecular weight of antigen, the more complex the chemical composition, the more complete the three-dimensional structure, and the farther the genetic relationship with immune animals, the stronger the antigenicity.

The physical state of antigen will also affect antigenicity, typically protein in food (especially animal food). In addition, a small amount of tyrosine (phenyl amino acid) and cholesterol can also enhance antigenicity.

Besides protein contained in mutton and seafood (such as chicken), chicken has a high protein content.

Protein content in mutton and chicken is very high. The protein content of mutton is as high as19.50g (per100g), and the protein content of chicken is19.30g (per100m).

In addition, cholesterol contained in chicken (106 mg) can also enhance human immune function by triggering antigen reaction.

However, I don't know what you said about bamboo shoots.

However, bamboo shoots contain a white nitrogen-containing substance, which does not exist in other foods. This is unique. This nitrogenous substance can promote digestion and increase appetite, and can be used to treat dyspepsia and anorexia, but it is not clear whether it is related to antigen reaction.

As for other similar foods, there are (ranked in the top ten by protein content)

Rapeseed oil, shark fin (dry), cuttlefish (dry), spirulina (dry), squid (dry), scallop, dried abalone, sea cucumber (dry) and mussel (dry),

yeast
