“…Recently, much attention has been focused on the utilization of TC peel, which exhibits strong various functional properties, including antioxidant, antimicrobial, anticancer, anti-inflammatory, antiobesity, and antihyperglycemic activities ( 3 , 4 ). While the left peel waste is a rich source of organic carbon, it has attracted much attention, but the problems of sustainability, bioavailability, and secondary pollution remain unsolved ( 5 ). More research regarding TC peel by-products has attracted public attention as well as environmental concerns.…”

The traditional hydrodistillation (HD) and ultrasound-assisted pretreatment extraction (UAPE) methods were proposed to obtain essential oil (EO) from Tribute citrus (TC) peels. The Box-Behnken design was employed to optimize the HD and UAPE procedures. Moreover, gas chromatography-mass spectrometry (GC-MS) and electronic nose (E-nose) were applied to identify the discrepancy of the extraction methods. The yield of EO extracted by UAPE (114.02 mg/g) was significantly higher than that by HD (85.67 mg/g) (p < 0.01) undergoing 40 min short time-consuming UPAE. A total of 28 compounds were extracted from the TC peels as terpenes were the predominant components. d-Limonene was the most vital compound in the T. citrus essential oil (TCEO), accounting for 86.38% of the total volatile concentration in HD and 86.75% in UAPE, respectively, followed by α-pinene, sabinene, γ-myrcene, and β-phellandrene. The chart of radar and graphic of the principal component analysis by E-nose displayed no significance, which was similar to the GC-MS results. This study demonstrated that UAPE is an efficient and short time-consuming method for TCEO extraction, which provides a promising method for the separation of EO from aromatic plant materials.

“…OGs, which are plant cell wall-derived oligomers specifically obtained from the homogalacturonan domain, are promising immune-stimulating molecules to fulfill this goal. They are extracted from fruit industry waste, such as apple byproducts and citrus peel [ 9 , 10 , 11 ]. These oligomers have been shown to participate in relevant plants mechanisms such as the trade-off between plant growth and defense.…”

The remarkable capacity of the generalist aphid Myzus persicae to resist most classes of pesticides, along with the environmental and human health risks associated with these agrochemicals, has necessitated the development of safer and greener solutions to control this agricultural pest. Oligogalacturonides (OGs) are pectin-derived molecules that can be isolated from fruit industry waste. OGs have been shown to efficiently stimulate plant defenses against pathogens such as Pseudomonas syringae and Botrytis cinerea. However, whether OGs confer resistance against phytophagous insects such as aphids remains unknown. Here, we treated Arabidopsis plants with OGs and recorded their effects on the feeding performance and population of M. persicae aphids. We also identified the defense mechanism triggered by OGs in plants through the analysis of gene expression and histological approaches. We found that OG treatments increased their resistance to M. persicae infestation by reducing the offspring number and feeding performance. Furthermore, this enhanced resistance was related to a substantial accumulation of callose and reactive oxygen species and activation of the salicylic acid signaling pathway.

“…(2015) optimized hydrolysis conditions of 1.3 mol TFA at 105°C for 3 h to hydrolyze 20 polysaccharides derived from mollusks; the analysis of disaccharides showed that its basic repeating unit is →4)‐GlcA(1→2)‐Man‐(1→). In addition, different methods have been proposed to certify that using two sequential acid technology to hydrolyze fruit wastes can obtain pectin oligosaccharides with degrees of polymerization 3–9, 6–8, and 16–55, respectively (Cano et al., 2021). The choice of partial acid hydrolysis conditions should consider the polysaccharide's molecular weight, glycosyl linkage types, backbone, and branched structures (Table 4).…”

Polysaccharides are promising biomolecules with lowtoxicity and diverse bioactivities in food processing and clinical drug development. However, an essential prerequisite for their applications is the fine structure characterization. Due to the complexity of polysaccharide structure, partial degradation is a powerful tool for fine structure analysis, which can effectively provide valid information on the structure of backbone and branching glycosidic fragments of complex polysaccharides. This review aims to conclude current methods of partial degradation employed for polysaccharide structural characterization, discuss the molecular mechanisms, and describe the molecular structure and solution properties of degraded polysaccharides. In addition, the effects of polysaccharide degradation on the conformational relationships between the molecular structure and bioactivities, such as antioxidant, antitumor, and immunomodulatory activities, are also discussed. Finally, we summarize the prospects and current challenges for the partial degradation of polysaccharides. This review will be of great value for the scientific elucidation of polysaccharide fine structures and potential applications.
