As primary coffee by-products, Arabica husks are largely discarded during coffee-drying, posing a serious environmental threat. However, could be used as potential material for extracting pectin polysaccharides, with high bioactivities and excellent processing properties. Thus, the present study aimed to extract polysaccharide from husk(s) (CHP). The CHP yield was calculated after vacuum freeze-drying, its average molecular weight (Mw) detected by gel permeation chromatography (GPC)....
Previous studies supposed that Amadori rearrangement products (ARPs) of peptides might have better umami-enhancing abilities. To confirm this, five ARPs (EP-ARP, AH-ARP, EE-ARP, β-AH-ARP, RFPHADF-ARP) were synthesized using a food-grade preparation method, and their chemical structures clearly demonstrated by mass spectrometry 1D/2D NMR. Sensory experiments showed had abilities than the corresponding in this research, though enhancing performance varied. synergistic effect with multiple...
The purpose of this study was to investigate the neuroprotective effect Arg-containing peptides from walnut storage protein sequences in scopolamine-induced zebrafish and further validate potential neuroprotection peptide enriched hydrolysates prepared by silico hydrolysis controlled enzymatic release. Results showed that derived with high abundance great bioactivity predicted bioinformatics displayed potent zebrafish, regulation neurotransmitter level antioxidant enzyme activity might be...
The metabolic modulation of major flavor precursors during coffee cherry ripening is critical for the characteristic formation. However, formation mechanism remains unknown. In present study, a colorimeter was employed to distinguish different maturity stages based on skin colors, and proteomics metabolomics profiles were integrated comprehensively investigate precursor dynamics involved in Arabica ripening. data obtained study provide an integral view pathways changes Moreover,...
The primary processing method of coffee plays a crucial role in determining its flavor profile. In this study, roasted beans were subjected to three methods, i.e., natural (SC), washed (WC), and honey (MC), that analyzed by LC-MS/MS GC-MS metabolomics. Additionally, sensory evaluation was conducted the Specialty Coffee Association America (SCAA) assess characteristics. results showed 2642 non-volatile compounds 176 volatile detected across methods. Furthermore, significant differentially...
To improve the insecticidal activity of (+)-nootkatone, a series 42 (+)-nootkatone thioethers containing 1,3,4-oxadiazole/thiadiazole moieties were prepared to evaluate their activities against Mythimna separata Walker, Myzus persicae Sulzer, and Plutella xylostella Linnaeus. Insecticidal evaluation revealed that most title derivatives exhibited more potent than precursor after introduction on (+)-nootkatone. Among all derivatives, compound 8c (1 mg/mL) best growth inhibitory (GI) M. with...
The study aimed to explore umami peptides derived from protein hydrolysates of Morchella esculenta. According the electronic tongue and sensory evaluation, ultrafiltration fractions (<3 kDa) exhibited strongest taste. overall flavor screened was significantly improved after Maillard reaction, based on nose analyses, content total free amino acid increased 387.35 589.30 μg/mL. A 37 with high confidence were identified using LC-MS/MS. Additionally, two novel through bioinformatics molecular...
Abstract This study aimed to compare chemical compositions, antioxidant activities, and acetylcholinesterase inhibitory activities of coffee flowers (ACF) leaves (ACL) with green beans (ACGB) Coffea Arabica L. The compositions were determined by employing high‐performance liquid chromatography–mass spectroscopy (HPLC–MS) gas (GC–MS) techniques. Antioxidant effects the components evaluated using DPPH ABTS radical scavenging assays, ferric reducing power (FRAP) assay. Their also evaluated....
The peptide MOp2 obtained from Moringa oleifera seeds showed good antimicrobial activity. However, the stability of its activity has not yet been studied. In present study, MOp2-loaded thiolated chitosan-stabilized (CMOp2) Pickering emulsion was prepared and applied to prolong shelf life grass carp. encapsulation rate 57.7% in CMOp2. addition, effects different concentrations CMOp2 solid particles pH on droplet size, zeta optional storage emulsions were evaluated; best condition for...
2-(2-Phenylethyl)chromones (PECs) are the primary constituents responsible for promising pharmacological activities and unique fragrance of agarwood. However, O-methyltransferases (OMTs) involved in formation diverse methylated PECs have not been reported. In this study, we identified one Mg2+-dependent caffeoyl-CoA-OMT subfamily enzyme (AsOMT1) three caffeic acid-OMT enzymes (AsOMT2–4) from NaCl-treated Aquilaria sinensis calli. AsOMT1 only converts caffeoyl-CoA to feruloyl-CoA but also...
Two series of novel fraxinellone-based thioethers containing 1,3,4-oxadiazole moiety were prepared as insecticidal agents against the oriental armyworm, Mythimna separata Walker. The structural assignment was based on spectroscopic and X-ray analysis data. Among all target compounds, compounds 4b , 4k 5b 5j 5k exhibited more potent activity with final mortality rates (FMRs) than 65%, especially FMR 75.9%, when compared toosendanin. Some interesting results structure–activity relationships...
