Abstract

This experiment was conducted to study the detoxification of steam explosion technology on free gossypol content of cottonseed meal. Seven treatments were exploded to commercially available cottonseed meal, which water material ratio was 0, 30% and 50% and retention time was 10, 20 and 30 s per ratio of water to material, except only 30 s was exploded on 0 water material ratio (control), the steam pressure was kept at 2.0 MPa for all treated cottonseed meal. Each treatment had three replicates. The content of free gossypol and protein solubility were analyzed for choosing a better steam exploded treatment, and then the amino acid content, and nutrient digestibility in vitro by simulative digestion system of pig were analyzed. The results showed that the detoxification efficient of free gossypol and protein solubility were increased with steam retention time increased, and they were firstly increased then decreased with the water material ratio increased. So according to free gossypol content and protein solubility, water material ratio of 30%, steam pressure of 2.0 MPa for 30 s was the better steam explosion treatment, which could remove 87.0% of free gossypol content to 85.0 mg/kg in cottonseed meal, and decrease protein solubility to 42.3%. Compared with the control group, steam explosion significantly decreased lysine content and arginine content (P<0.01), and significantly decreased the digestibility of crude protein and lysine in vitro (P<0.01), but had no significant effect on the digestibility of dry matter and gross energy in vitro (P>0.05). In conclusion, steam explosion treatment can decrease the content of free gossypol, protein solubility, lysine content, arginine content, crude protein digestibility and lysine digestibility in vitro. Water material ratio of 30%, steam pressure of 2.0 MPa for 30 s is chosen as the better steam explosion treatment.
