Since enterohemorrhagic Escherichia coli O157, Salmonella, etc., sometimes contaminate animal feces and may cause infectious diseases to humans, it is important to remove pathogenic bacteria from domestic animal waste. For the purpose, we examined the antibacterial activity of chaff vinegar. We found that the chaff vinegar inhibited the growth of pathogenic bacteria immediately in vitro but not...

background and objective: garlic, in different types, is a very common food ingredient all over the world. traditionally, garlic is fermented in grape vinegar to produce garlic pickles; in this study, to produce a novel fermented food, garlic was fermented in kombucha beverage; then, antibacterial and chemical properties and color changes of garlics fermented in kombucha and vinegar were compar...

In order to achieve non-destructive of mature vinegar varieties, a fast discrimination method was put forward based on Visible_near infrared reflectance (NIR) spectroscopy. The FieldSpec3 spectrometer was used for collecting 20 sample spectra data of the three kinds of mature vinegar separately. Then principal component analysis (PCA) was used to process the spectral data after pretreatment usi...

The antioxidant and antibacterial activities of wood vinegar from Litchi chinensis, and its components have been studied. The chemical compositions of wood vinegar were analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 17 chemical compounds were identified, representing 83.96% of the compositions in the wood vinegar. Three major components, included 2,6-dimethoxyphenol (syrin...

Introduction: Gardnerella vaginalis is a significant pathogen associated more frequently with genital and rarely extragenital infections in women of reproductive age. Few natural antimicrobial agents such as soap nut, garlic, calendula oil are reported to inhibit the growth of G.vaginalis. The present study was intended to investigate the antibacterial and antibiofilm actions of Tea Tree oil an...

This paper proposes two ways to fix the broken Square-Vinegar signature scheme. We give heuristic arguments as well as experimental evidence to support the security claims. The first variant, Square-Vinegar with Embedding, uses a simple modification that nonetheless changes the nature of the public key polynomials. The second, 2-Square-Vinegar, is a more significant overhaul of the construction...

Two gas chromatography-olfactometry (GC-O) techniques were used to screen targeting compounds with an impact on the perceived quality of Sherry vinegar: detection frequency and aroma extract dilution analysis (AEDA). The GC-O study revealed the presence of 108 aromatic notes, of which 64 were identified. Diacetyl, isoamyl acetate, acetic acid, and sotolon reached the highest frequency and flavo...

We evaluated the transfer of Pb from shot to meat during the preparation of breasts of quails with 0, 1, 2 or 4 embedded Pb shot. A traditional Spanish recipe was used which utilizes vinegar during cooking to enhance the long-term preservation of the meat. The effect of the acidic conditions generated by the vinegar on Pb transfer was compared with the same recipe when the vinegar was substitut...

Vinegar has long been added to foods in the home and in the commercial packing plant as a flavoring element; in addition, it has adefinite preservative action against spoilage microorganisms. Any toxic effect of vinegar is undoubtedly due to its acetic acid content. Levine and Fellers (1940) showed that the toxicity of acetic acid is not due to pH alone although an increase in the hydrogen ions...
