This study aimed to investigate the effects of different preheating treatments （steaming， roasting and microwave） of flaxseed on cyanide content， nutritional composition， physicochemical properties， color and oxidative stability of flaxseed meal. The three preheating methods of flaxseed all significantly decreased the hydrocyanic acid （HCN） contents. By contrast， microwave was the most effective detoxification method. After 5 min of microwave treatment， the HCN content in flaxseed was reduced from 94.65 ± 1.68 mg/kg to 7.80 ± 0.57 mg/kg. In addition， the three preheating methods all significantly increased the polyphenol content， thiobarbituric acid reactive substances （TBARS）， peroxide value （POV）， and a*value， and slightly decreased polyunsaturated fatty acid （PUFA） contents， but significantly decreased total amino acid contents as well as L*， W*and b*values. Interestingly， the three preheating methods all improved the oxidative stability and color stability of flaxseed upon accelerated storage under 40 °C. Compared with steaming （120 ℃ for 20 min） and roasting （100 ℃ for 40 min）， microwave （560 W for 4 min） is recommended for decreasing cyanide content， as well as enhancing the flaxseed' stability and qualitative attributes.

Salmonella grows better under aerobic conditions as a facultative anaerobic foodborne pathogenic bacteria. The oxygen-scavenging activity of Lactococcus lactis in the intestinal tract is a promising strategy for preventing Salmonella infection. In this study， the aerobic respiration requirement and preventive mechanism of Lactococcus lactis subsp. lactis (L. lactis) KLDS 4.0325 in murine models infected by Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) SL1344 were investigated. Results indicate that L. lactis KLDS 4.0325 is capable of aerobic respiratory metabolism in the host intestine when exogenous heme exists， and decrease intestinal oxygen concentration， which in turn trigger autophagy of intestinal cells to reduce S. Typhimurium load， improve gut microbiota composition， alleviate intestinal barrier injury and inflammation response. These results suggest that aerobic respiration L. lactis KLDS 4.0325 can prevent S. Typhimurium infection in a new way in which by restoring intestinal cell hypoxia， maintaining immune balance and regulating intestinal flora.
