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.

Knowledge distillation(KD) enhances student network generalization by transferring dark knowledge from a complex teacher network. To optimize computational expenditure and memory utilization, self-knowledge distillation(SKD) extracts dark knowledge from the model itself rather than an external teacher network. However, previous SKD methods performed distillation indiscriminately on full datasets, overlooking the analysis of representative samples. In this work, we present a novel two-stage approach to providing targeted knowledge on specific samples, named two-stage approach self-knowledge distillation(TOAST). We first soften the hard targets using class medoids generated based on logit vectors per class. Then, we iteratively distill the under-trained data with past predictions of half the batch size. The two-stage knowledge is linearly combined, efficiently enhancing model performance. Extensive experiments conducted on five backbone architectures show our method is model-agnostic and achieves the best generalization ***, TOAST is strongly compatible with existing augmentation-based regularization methods. Our method also obtains a speedup of up to 2.95x compared with a recent state-of-the-art method.
