Abstract “Zhongbai” papaya fruit were treated with 15 mmol/L glycine betaine ( GB ) and then refrigerated at 6°C for 40 days to study the influence of on chilling injury (CI) possible mechanism associated energy metabolism. The results exhibited that treatment remarkably reduced CI severity as indicated by lower index during storage. lowered electrolyte leakage malondialdehyde content, which accounted maintenance membrane integrity lipid peroxidation. Moreover, improved status revealed...

This study evaluated the physicochemical properties of oils extracted from steam-exploded camellia seed (Camellia oleifera Abel.). Steam pressure, resident time, fatty acid composition, total phenolics, tocopherol, squalene, and sterol contents, volatile compounds were determined. 1H NMR FTIR spectra performed for structure oil. has found highest yield oil was 86.56% obtained when steam explosion pretreatment at 1.6 MPa 30 s. Oil by exhibited favorable stronger antioxidant activities...

Abstract BACKGROUND Cyromazine and acetamiprid are widely applied as pesticides in agriculture, causing increasing concerns about their residues crops. In this study, cyromazine, mixture were to cowpea investigate degradation dynamics perform a dietary risk assessment. RESULTS The dissipation behavior of cyromazine the single‐ mixed‐pesticide groups followed first‐order kinetics, with linear correlation coefficient 0.910 0.987. half‐lives 1.56–11.18 days four different matrices. half‐life...

A variety of pesticides are often used in agricultural management to control target pests but may trigger disruptions the metabolism nontarget organisms, ultimately affecting crop quality. Acetamiprid (ACE) and cyromazine (CYR) two frequently insecticides on cowpea, so it is critical understand whether these cause metabolic disorders cowpea quality changes mechanism by which they do so. Here, we metabolomic transcriptomic methods explore mechanisms effects ACE, CYR, their mixture (MIX)...

Pesticide residues have been one of the food safety problems that plague consumers. It is necessary to develop validated detection methods monitor pesticide in food. In this study, fluopyram was analyzed fruits (banana, grape, and citrus) vegetables (tomato, cucumber, cowpea, pepper, eggplant, potato) by optimizing QuEChERS combination with GC-MS/MS. The recoveries all matrices ranged from 87.02% 101.42% RSD below 9.25%. matrix effect ranging −1.41% 17.67%. Finally, market investigation...

Phenolics have been used to suppress the formation of advanced glycation end products (AGEs) in food; however, enhancing their thermostability and photostability foods remains a key issue. Ferulic acid (FA), quercetin (QT), vanillic (VA), which reduce production AGEs, were embedded bovine β-lactoglobulin (β-LG) interaction mechanism was investigated. Fluorescence experiments demonstrated that FA QT displayed typical static quenching, while VA caused fluorescence sensitization β-LG....

β-Lactoglobulin (β-LG) is a whey protein with multiple binding sites for bioactive phenolics. Encapsulation of components in β-LG could enhance their activity and stability. In this study, vanillic acid (VA), ferulic (FA), quercetin (QT) were encapsulated β-LG. The resulting complex was studied by fluorescence spectroscopy, isothermal titration calorimetry, molecular docking, dynamics simulations. β-LG–tri-ligand successfully formed via an exothermic process when the ligands added sequence...

We investigated the effects of low pH on photosynthesis, chlorophyll fluorescence, and mineral contents leaves ginger plants under salt stress. This experiment involved four treatments: T1 (pH 6, 0 salinity), T2 4, T3 100 mmol L −1 salinity) T4 salinity). study showed that photosynthesis (Pn, Gs, WUE Tr) fluorescence (qP, Φ PSII, Fv/Fm) significantly decreased stress; however, all parameters low-pH treatment stress recovered. Moreover, reduced content Na enhanced K, Mg, Fe Zn in Taken...

Summary The nutritional value of Hainan camellia oil is incomparable to other places, and expensive, so unscrupulous businessmen often mix edible oils into them for illegal profit. This study detected the changes volatile components in adulterated with five (peanut, soybean, corn, rapeseed, sunflower oils) using comprehensive two‐dimensional gas chromatography quadrupole time‐of‐flight mass spectrometry (HS‐SPME‐GC × GC‐Q‐TOFMS). principal component analysis (PCA) score plot showed that pure...

Summary We aimed here to investigate the ability of steam‐exploded camellia seed protein (SECSP) in stabilising oil‐in‐water emulsion comparison with soy isolate (SPI). Emulsions different SECSP and SPI contents (0.5, 1, 1.5 2 g 100 mL −1 ) were formulated effect concentration on droplet size, zeta (ζ)‐potential, physical stability bioaccessibility was examined. The increased increasing concentration. characterised by smaller sizes, higher surface charge better than emulsion. Furthermore,...

Abstract Mulberry ( Morus alba L.) leaf, a “source of both medicine and food”, contains antioxidant ingredients such as flavonoids, alkaloids polyphenols. The effects 6-benzylaminopurine (6-BA) treatment on plant growth flavonoid contents in mulberry leaves were investigated this study. expression rutin (Rut), chlorogenic acid (ChA), isoquercitrin (IQ) astragaloside IV (Ast) related genes the synthesis pathways was leaves. results showed that 6-BA significantly promoted differentiation well...

A rapid and sensitive method for the simultaneous determination of cyromazine acetamiprid in cowpeas by high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) was developed. The cleanup performance primary secondary amine (PSA), C18 graphitised carbon black (GCB) carried out optimise sample preparation step. analytical showed satisfactory specificity, selectivity, linearity (R2 > 0.99) recoveries (85.8–109.0%), relative standard deviation (intra-day RSD)...

<title>Abstract</title> Pesticide residues have always been one of the food safe issues troubling consumers. Agricultural production is usually accompanied by a mixture pesticides, and pesticide are not only present on plants but also contaminate soil in environment. In this study, 15 pesticides commonly found cowpea were analyzed optimizing QuEChERS combining GC-MS/MS HPLC. Various extractants different methanol water ratios evaluated to extract from soil.C18, PSA GCB used purify extracts,...

Abstract BackgroundSalt stress is one of the abiotic stresses that affect plant growth, and it mainly reduces biomass plants by affecting their photosynthesis. However, little known about mechanisms which low pH improves growth under salt stress. The effects on photosynthesis, chlorophyll fluorescence mineral content in ginger ( Zingiber officinale Roscoe) leaves were investigated.ResultsIn this study, we found height fresh weight, photosynthesis parameter (Pn, Gs, WUE Tr), pigment...
