Camellia oleifera leaves were byproduct of the C. oleifera industry which was rich in polysaccharides. Deep eutectic solvent-dual enzyme system (DES-dEAE) was established to achieve the simultaneous hydrolysis reaction of dual enzymes and DES extraction.

Heat pretreatment plays a crucial role in affecting the quality, colour and aroma of camellia oil during the extraction process. This study aimed to investigate the effects of steaming, stir-frying, roasting, microwave and infrared treatment on the flavour and physicochemical quality of camellia seeds. The results indicated that, compared with unpretreated samples, the heat-pretreated ones exhibited increased oil content and browning degree, imparting a caramel colour with toasty and nutty flavours.

Plant polysaccharides exhibit many biological activities that are remarkably affected by molecular size and structures. This study aimed to investigate the degradation effect of ultrasonic-assisted Fenton reaction on the polysaccharide (PP). PP and its three degradation products (PP3, PP5, and PP7) were obtained from optimized hot water extraction and different Fenton reaction treatments, respectively.
