Biofilms can persist in food industry environments leading to repeated cross-contamination, thus threatening human health. Slightly acid electrolyzed water (SAEW) and ultrasound have emerged as environmentally-friendly antimicrobial agents. However, their bactericidal efficacy is not high when used alone. In the present study, effect of combined with SAEW on removing Listeria monocytogenes biofilms from a glass surface was evaluated. were treated by immersion sterilized deionized (control...

Tiger nuts were enzymatically hydrolyzed by Alcalase and then separated purified ultrafiltration classification Sephadex G-15 fractionation to obtain tiger nut peptides. Their chemical antioxidant activities cytoprotective functions on HepG2 Caco-2 cells systematically evaluated in this study. The peptides (TNP) found perform excellent activity supported their cell behaviors, amino acid composition, morphological observation. Higher 1,1-diphenyl-2-picrylhydrazyl radical scavenging (DPPH•...

In this study, eight cultivars of hempseed were collected from different regions China for analysis physiochemical properties and chemical composition, as well seed indexes proximate composition kernel. The results indicated that Yunma No. 1 Bama Huoma, with more than 50% oil 30% protein in dehulled seed, could be considered extraction material source respect to kernel yield. Iodine values ranging 153.6 169.1 g/100 g reflected the high degree unsaturation. concentration unsaturated fatty...

This study investigated the antifungal effect of curcumin-mediated photodynamic inactivation (PDI) with ascorbic acid (Vc) as a synergist on Penicillium italicum and its biofilms, evaluated efficacy in inactivating P. fresh-cut orange. Results showed that number spores decreased by 4.61 Log CFU/mL when concentration curcumin, Vc illumination time was 75 μmol/L, 250 mg/L 20 min, respectively. After PDI treatment, cell structure destroyed leakage contents observed. Mature biofilms were formed...

It is inevitable for polyphenols and polysaccharides to interact during food preparation. Modifications in microstructure can lead changes the physical chemical properties of systems, which turn may influence nutritional characteristics functional activities food. Recent studies have shown that, addition traditional Chinese medicine compounds, certain natural exhibit significant anti-inflammatory antioxidant properties. These compounds are also associated with beneficial therapeutic effects...

Sprouts have many advantages, such as high nutritional value and simple cultivation conditions. In recent years, the loss rate of sprouts due to microbial contamination has been 40%, it is necessary strengthen control technology reduce losses. Current methods issues a narrow bactericidal spectrum cost contamination, whereas slightly acidic electrolyzed water (SAEW), new type disinfectant, can solve these problems. present study, efficacy SAEW treatments in disinfection oat during germination...

In the present work, bactericidal efficacy and mechanism of slightly acidic electrolyzed water (SAEW) on L. monocytogenes were evaluated. The results showed that strains killed completely within 30 s by SAEW whose available chlorine concentration (ACC) was higher than 12 mg/L, it confirmed ACC is main factor affecting disinfection SAEW. Moreover, our demonstrated could destroy cell membrane monocytogenes, which observed SEM FT-IR, thus resulting in leakage intracellular substances including...

Slightly acidic electrolytic water (SAEW) treatment for seed germination is a promising technique sustainable agriculture. This study investigated the antioxidant activity of germinated sesame seeds treated with SAEW first time. Specifically, impact and correlation on activities total phenols, flavonoids, oxidase in were examined. The results showed that low ACC inhibited germination, high promoted buds 30 mg/L 50 lower phenolic flavone content compared to tap water. In contrast, had no...

Previous studies have confirmed that electrolyzed water had disinfection potential and enrich functional nutrients during seed germination. However, the effect of slightly acidic (SAEW) on quality safety peanut sprouts is poorly understood. In this study, influence mechanism SAEW antibacterial, antioxidant capacity, allergenicity were investigated. Although SAEW-3 with 33.85 mg/L available chlorine concentration (ACC) showed better antibacterial effect, SAEW-2 (23.74 ACC) group has a 20% 50%...

Abstract Here, the bactericidal efficacy and mechanism of action combination alkaline electrolyzed water (AlEW) acidic (AcEW) on Pseudomonas aeruginosa biofilm were investigated, in comparison with single AcEW or AlEW treatment. The mature P. was formed at 120 h cultivation. number bacteria decreased by 7.87 2.51 Lg CFU/mL after treatment for 8 min, while sterilization rate reached 92.2% 33.1%, respectively. group (7 min) co‐action (1 had a 85%. (3 (5 showed best efficacy. With this...

Abstract Background Lentinan can inhibit the proliferation of many kinds tumor cells, and some studies have shown that lentinan growth tissue by directly killing cells. The purpose this study was to investigate immunoprophylaxis effect mechanism specific antigen induced on liver cancer in mice. Methods immunogen prepared which lentinan. And two different mouse H22 models (ascites solid tumor)were established after immunized. immune organ index mice each group were measured. In order analyze...

<title>Abstract</title> The antioxidant activity of the peptides from tiger nut was investigated for first time. (TNP) were found to perform excellent supported by their chemical and cell behaviors, amino acid composition, morphological observation. Higher 1,1-diphenyl-2-picrylhydrazyl radical scavenging ferric ion reducing power observed in TNP with more hydrophobic acids compared traditional soybean peanut peptides. Furthermore, could effectively protect H₂O₂-induced...

Abstract A highly sensitive and reliable fluorescence immunoassay based on the inner-filter effects (IFE) of quantum dots (QDs) was developed for detection norfloxacin (NOR) in animal-origin foods. Briefly, enzymatic formation horseradish peroxidase conventional ELISA effectively quenched QDs through IFE, then absorption signal transformed to fluorescent signals, resulting a higher sensitivity NOR foods.The limit this method 0.20 µg L − 1 standard solution, which 12-fold more than (2.50 )....

Food enzymology and enzyme engineering is an important professional course of food science. The includes the basic theory enzymology, technology application enzymes in industry.
