The special structure of yeast cell wall has an adsorption effect on mycotoxins. There are polysaccharides, proteins, and lipids on the cell wall, which can adsorb mycotoxins through hydrogen bonds, ionic bonds, and hydrophobic forces.
Glucomannan 葡甘露聚糖酵母细胞壁的特殊结构对真菌毒素具有吸附作用。细胞壁上有多糖、蛋白质和脂质,可通过氢键、离子键和疏水力吸附霉菌毒素。
Glucomannan is an active ingredient in the yeast cell wall that has a certain adsorption capacity for mycotoxins. In vitro studies have shown that glucomannan can adsorb up to 75% of gibberellin. Aflatoxin is 92%; Fumarisin accounts for 59%
Adsorption of corn gibberellin by glucomannan and clay葡甘露聚糖和粘土对玉米赤霉素的吸附葡甘露聚糖是酵母细胞壁中的一种活性成分,对真菌毒素有一定的吸附能力。体外研究表明,葡甘露聚糖可以吸附高达75%的赤霉素。黄曲霉毒素占92%;富马菌素占59%
Glumanannan combined with other clay like fungal toxin adsorbents (zeolite, calcium sodium silicate)
Compared the effectiveness of combined use with mycotoxins. The results showed that piglets fed with a glucomannan diet had higher daily weight gain and feed conversion rate than other treatment groups. The adsorption effects of glucomannan and sodium calcium silicate on aflatoxins in moldy chicken feed were compared. At the highest dose, aflatoxin can absorb over 80% of feed, but the dose of glucomannan is much lower. The adsorption effect of glucomannan on corn gibberellin was compared with that of three other clay products. They found that glucomannan adsorbed about 70% of corn gibberellin within 10 minutes after addition, making it superior to aluminum silicate adsorbents. In acute poisoning cases, i.e. in feed containing high concentrations of aflatoxin, glucomannan can bind up to 2000 pg/kg with aflatoxin.
conclusion
According to the definition of "ideal fungal toxin adsorbent", yeast cell walls have the ability to simultaneously adsorb multiple fungal toxins, with low and effective addition amounts, high stability in the gastrointestinal tract, and degradability after discharge. It is a very promising fungal toxin adsorption product.
