Extraction of polysaccharides from Camellia oleifera leaves by dual enzymes combined with deep eutectic solvents screened by ANN and COSMO-RS.

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.

Volatile profiles and characteristic odorants in camellia seeds with different heat pretreatments.

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.

Extraction and identification of polyphenol from Camellia oleifera leaves using tailor-made deep eutectic solvents based on COSMO-RS design.

Camellia oleifera leaf is a rich source of polyphenols. In this study, 50 polyphenolic compounds from C. oleifera leaves was identified by UHPLC-Q-TOF-MS/MS.

Extraction, Structural, and Antioxidant Properties of Oligosaccharides Hydrolyzed from by Ultrasonic-Assisted Fenton Degradation.

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.
