Abstract A novel polysaccharide (PFP1) with an average molecular weight of 2.02 × 10 5 g/mol was isolated from Passiflora foetida fruits through hot water extraction, ethanol precipitation and column chromatography. The structure of PFP1 was determined by GPC-MALS-RI, IC, FT-IR, GC–MS and NMR. The structural analysis showed that PFP1 was a heteropolysaccharide and composed of mannose (48.83%), galactose (32.46%), glucose (6.21%), arabinose (5.88%), fructose (2.24%), galacturonic acid (2.20%), xy...

Abstract To monitor illegal addition of tadalafil and its analogues in health food, a new polyclonal antibody was prepared by immunizing New Zealand white rabbits with a common skeleton structure hapten combined with an unsaturated linear alkyl arm hapten strategy, which could simultaneously recognize tadalafil, amino tadalafil and N-Desmethyl tadalafil. A microwell lateral flow immune- chromatographic assay (mwLFIA) method combined with simple sample pretreatment was developed. The mwLFIA showe...

Abstract In our study, a 3D printed smartphone-based detection device integrated with solid phase latex microsphere immunochromatography platform (SIAP) is developed for sensitive and quantitative detection of zearalenone (ZEN) in cereals and feed. A user-friendly Android application (App) is self-written to analyze, report and share the detection results. The cut-off values of latex microsphere immunochromatography for ZEN in cereals and feed were 2.5 and 3.0 μg/kg, respectively. The SIAP detec...

Abstract Atypical porcine pestivirus (APPV), a newly discovered member of the genus Pestivirus , is considered to be associated with congenital tremors (CT) in piglets. From June 2016 to January 2018, 440 serum and tissue samples from CT-affected piglets in Anhui, Guangdong and Guangxi provinces were collected to detect APPV. The results showed a high level of 63.4% preference for APPV in 27 swine farms and complicated co-infection cases between APPV and other 12 swine viruses. Meanwhile, 12 nov...

Abstract Alternariol (AOH), a secondary metabolites of the genus Alternaria , is a genotoxic mycotoxin. Because the previous “Mannich antigen” for AOH readily underwent unstable induction, a new AOH hapten was designed for inducing a high-quality antibody against AOH using a conjugate of the AOH carboxymethyl derivative with a carrier protein as the immunogen. A competitive indirect chemiluminescence enzyme immunoassay (ciCLEIA) for AOH was optimized and showed good sensitivity (limit of detecti...

The aim of this work was to clarify the formation of ethyl carbamate (EC) and its influence factors throughout the production process of Cantonese soy sauce. The results showed that EC was not detected in the koji-making and early moromi fermentation stages, but started to be generated when pH of the moromi decreased to about 4.9—at the same time, the levels of ethanol, urea and citrulline increased significantly. Most EC was formed during raw soy sauce hot extraction (40.6%) and sterilization (...

Abstract An electrochemical immunosensor for ultrasensitive detection of acrylamide (AA) in water and food samples was developed. SnO 2 -SiC hollow sphere nanochains with high surface area and gold nanoparticles with good electroconductivity were fabricated onto the surface of a glassy carbon electrode pre-coated with chitosan. The coating antigen (AA-4-mercaptophenylacetic acid-ovalbumin conjugate, AA-4-MPA-OVA) was immobilized on the electrode. Polyclonal antibody specific for AA-4-MPA was con...

ABSTRACTIn this study, dehydroepiandrosterone (DHEA) hapten and high sensitivity polyclonal antibody against DHEA were prepared, a competitive indirect enzyme-linked immunosorbent assay (ciELISA) and lateral flow immunochromatography (LFA) for the determination of DHEA in slimming products were developed for the first time. The sample pretreatment was very simple and fast, the limit of detection (LOD) of the ciELISA for DHEA in slimming products was 9.6 μg/kg. The average recoveries of slimming ...

ABSTRACTIn this work, a rapid, convenient and sensitive Au nanoparticle-based immunochromatographic sensor (AuNPs-ICS) for simultaneous detection of various tadalafil adulterants in health food was established for the first time, based on one high affinity and broad-spectrum antibody through skeleton-specific hapten design according to the common structure of tadalafil drugs. This immunochromatographic sensor was developed by the polyclonal antibody conjugated with AuNPs and the IC50 was 10.04 n...
