    AN ABSTRACT OF THE THESIS OF Larry Stanford Merrifield for the M.S. in Food Science (Name) (Degree) (Major) Date thesis is presented June 26, 1964 Titie FACTORS AFFECTING THE ANTIMICROBIAL ACTIVITY OF VITAMIN K 5 Abstract approved (M^jor Tp&Sfesso/) Vitamin K, 4-amino-2-methyl- 1-naphthol hydrochloride, a 5 water soluble analog of vitamin K has been shown to possess an anti- microbial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preserva- tive, and it was the purpose of this study to investigate some of the factors which might affect the antimicrobial activity of vitamin K in order to add insight into its more effective use as a food preserva- tive. Pure cultures of Escherichia coli, Bacillus subtilis, Proteus vulgaris, Staphlococcus aureus, and Pseudomonas fluorescens were utilized. The effect of the method of application of vitamin K on Escherichia coli; the effect of purity of vitamin K against Escherichia coli; the bactericidal concentrations required for Escherichia coli, Bacillus subtilis, Proteus vulgaris, Staphlococcus aureus, and Pseudomonas fluorescens; the effect of an absence of oxygen; the effect of contact time with Escherichia coli; the effect of initial count/ml of Escherichia coli; and the synergistic action in combination with propylene glycol were studied. The results demonstrated that air oxidation of vitamin K was 5 necessary to obtain maximum inhibitory activity against Escherichia coli. The use of white, crystalline vitamin K synthesized in the laboratory, as compared to partially oxidized commercial prepara- tions, gave better results against Escherichia coli.

  • Scientific Opinion on the Safety and Efficacy of Vitamin K3 (Menadione
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Directory of Open Access Journals EFSA Journal 2014;12(1):3532 SCIENTIFIC OPINION Scientific Opinion on the safety and efficacy of vitamin K3 (menadione sodium bisulphite and menadione nicotinamide bisulphite) as a feed additive for all animal species1 EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)2,3 European Food Safety Authority (EFSA), Parma, Italy ABSTRACT Vitamin K describes a group of lipophilic vitamins that exist naturally in two forms: vitamin K1 (phylloquinone, found in green plants) and vitamin K2 (a group of menaquinones synthesised by bacteria in the intestine). Vitamin K3 (or menadione) is a synthetic form of vitamin K without a side chain. To become active, menadione needs to undergo prenylation. Vitamins K1, K2 and K3 are metabolically activated in the liver to become co- factors in the activation of vitamin K-dependent proteins, which are important for normal blood coagulation, and normality of bones and arteries (Gla proteins). Acute toxicity of menadione or its derivatives is reached at levels exceeding the requirements by a factor of at least 1 000. Menadione sodium bisulphite (MSB) and menadione nicotinamide bisulphite (MNB) are safe for all animal species at practical use levels in feed. The use of MSB in water for drinking is likely to increase the exposure of target animals to chromium(VI). Therefore, the FEEDAP Panel has concerns about the safety of MSB when administered by this route. The use of MSB and MNB in animal nutrition does not give rise to safety concerns for consumers.

  • VITAMIN K SUBSTANCES 1. Exposure Data
    VITAMIN K SUBSTANCES Vitamin K comprises a group of substances, which are widespread in nature and are an essential co-factor in humans in the synthesis of several proteins that play a role in haemostasis and others that may be important in calcium homeostasis. The K vitamins all contain the 2-methyl-1,4-naphthoquinone (menadione) moiety, and the various naturally occurring forms differ in the alkyl substituent at the 3-position. Phylloquinone (vitamin K1) is 2-methyl-3-phytyl-1,4-naphthoquinone and is widely found in higher plants, including green leafy vegetables, and in green and blue algae. The menaquinones (formerly vitamin K2) have polyisoprenyl substituents at the 3-position and are produced by bacteria. The compound menadione (formerly vitamin K3) lacks an alkyl group at the 3-position but can be alkylated in vivo in some species. Several synthetic water-soluble derivatives, such as the sodium diphosphate ester of menadiol and the addition product of menadione with sodium bisulfite, also have commercial applications (National Research Council, 1989; Gennaro, 1995; Weber & Rüttimann, 1996). 1.
