Key points

The results showed that the Cd content in fresh AbM was 10.27 mg kg(-1) DM. The cooking treatments of boiling and microwaving with water significantly decreased Cd contents in fresh AbM by 36.4% and 30.2% (P<0.05), respectively
Cd in fresh AbM showed the highest bioaccessibility of 77.8% during the biomimetic digestion in stomach, followed by that of 69.4% from the gastrointestinal digestion
Cooking treatments also significantly lowered the bioaccessibility of Cd (P<0.05)
Cd in boiled AbM showed 50.7% and 46.1% bioaccessibility during the gastric and gastrointestinal procedures
While, Cd in microwaved AbM showed 58.2% and 50.4% bioaccessibility
This study confirmed that the health risk assessment of AbM depending on the total Cd levels in fresh AbM was inaccurate, especially for the products domestically cooked

Metadata-grounded summary

Citation abstract

Bioaccessibility of cadmium (Cd) in fresh and cooked Agaricus blazei Murill (AbM) was studied by an in vitro biomimetic digestion system in this paper. The results showed that the Cd content in fresh AbM was 10.27 mg kg(-1) DM. The cooking treatments of boiling and microwaving with water significantly decreased Cd contents in fresh AbM by 36.4% and 30.2% (P<0.05), respectively. Cd in fresh AbM showed the highest bioaccessibility of 77.8% during the biomimetic digestion in stomach, followed by that of 69.4% from the gastrointestinal digestion. Cooking treatments also significantly lowered the bioaccessibility of Cd (P<0.05). Cd in boiled AbM showed 50.7% and 46.1% bioaccessibility during the gastric and gastrointestinal procedures. While, Cd in microwaved AbM showed 58.2% and 50.4% bioaccessibility. This study confirmed that the health risk assessment of AbM depending on the total Cd levels in fresh AbM was inaccurate, especially for the products domestically cooked.
