Alicyclobacillus spp. are a group of thermophilic, acidophilic, spore-forming bacteria, some of which cause spoilage in commercially pasteurized fruit and vegetable juice products including apple, orange, tomato and carrot juice. In this study, we characterized seven isolates of Alicyclobacillus (14-2, KF, A-Gala 2-1, C-Fuji 6, Gala 9-2, 1016, 18-1) and a reference strain A. acidiphilus DSM 145...

BACKGROUND Alleles of the receptor gene TAS2R38 are responsible in part for the variation in bitter taste perception of 6-n-propylthiouracil (PROP) and structurally similar compounds (eg, glucosinolates in cruciferous vegetables). At low concentrations, people with the PAV ("taster" amino acid sequence) form of TAS2R38 perceive these bitter compounds, whereas most with the AVI ("nontaster" amin...

In this study Response Surface Methodology was used to optimize process conditions and to evaluate the effect of ultrasound on quality attributes (antioxidant activity, pH, total soluble solid, turbidity) and the inactivation of Escherichia coli bacteria in carrot juice. Independent variables in this study were temperature (25-50°C), time (20-40 min) and frequency (0-130 kHz). In this study the...

A human intervention study was conducted to determine the effect of the consumption of carotenoid-rich vegetables on the immune system. Subjects, (twenty-three men), who were non-smokers, were not restricted in their daily diet, except that they had to abstain from fruit and vegetables high in carotenoids throughout the whole study period. The study was divided into four periods, each lasting 2...

Crown-gall tumor cells induced by Agrobacterium tumefaciens (Sm. and Town.) Conn develop from normal plant cells by the action on them, in sequence, of several causal factors.1 Inoculations of susceptible species frequently result in fairly uniform tumors in 100 per cent of the trials. Inoculations of other plant species are not always successful or may result in tumors showing considerable siz...

The antimicrobial activity of partially purified bacteriocin produced during natural lactic acid fermentation of carrot, radish and cucumber was assessed and characterized. Out of ten strains, the isolated strain CA 44 of Lactobacillus genus from carrot fermentation produced bacteriocin with maximum antimicrobial activity against Escherichia coli, Staphylococcus aureus and Bacillus cereus, thou...

The high rate of hypertension causes to be a problem that must overcome. In herbal medicine with the therapy giving wordu juice (honey carrots), it contains potassium which can maintain blood pressure and aceticolin helps improve vessel circulation. To determine effect Wordu (carrots honey) on reduction in patients hypertension. research design used pre-experimental one group pretest-posttest d...

This study aimed at investigating the regulatory system of bacteriocin synthesis by Lactobacillus plantarum strains in vegetables and fruits in a model system. Sterile and neutralized cell-free supernatant (CFS) from L. plantarum strains grown in MRS broth showed in vitro antimicrobial activities toward various indicator strains. The highest activity was that of L. plantarum C2. The antimicrobi...
