Turnip (Brassica rapa var. rapa L.), beetroot (Beta vulgaris L.) and carrot (Daucus carota L.) are common vegetables in South Africa. The allelopathic potential of aqueous leaf and root extracts of Aloe ferox Mill.a highly valued medicinal plantwas evaluated against seed germination and seedling growth of the three vegetables in Petri dish experiments. The extracts were tested at concentrations...

Polygalacturonase (PG) was purified from Erwinia carotovora EC. A hybrid cosmid, pSH711, that encodes PG activity but not pectate lyase activity was identified from an E. carotovora genomic library by an immunological screening method. A cell extract of Escherichia coli cells containing pSH711 was able to produce plant tissue maceration when spotted on carrot, potato, or turnip slices. In addit...

The objective of this study was to evaluate the contamination of vegetables, fruits and soil with zoonotic parasite eggs on organic and conventional farms in south-eastern Poland. To evaluate the contamination with eggs of zoonotic parasites, examinations were conducted on 8 conventional and 11 organic farms in south-eastern Poland from May-October in 2008 and 2009. The following fruit and vege...

Fresh agricultural produce can harbor pathogenic microorganisms that can cause serious illnesses when transmitted to the human beings after consumption. The frequency of outbreaks from the consumption of contaminated fresh vegetables and fruits has amplified in recent decades (1). True and opportunistic human pathogens have been reported with foodborne outbreaks due to their continuously increa...

The osmotic dehydration (OD) process consists of the removal of water from a material during which the solids from the osmotic solution are transported to the material by osmosis. This process is commonly performed in sucrose and salt solutions. Taking into account that a relatively high consumption of those substances might have a negative effect on human health, attempts have been made to sea...

  ABSTRACTBackground : The presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. Measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations.   Materials and methods: A total of 56 samples from 18 different foodstuf...

Human manipulation of wild progenitors during crop domestication has led to the foundation of modern agriculture ( Zohary and Hopf, 2000 ; Glémin and Bataillon, 2009 ). A common suite of traits including loss of seed shattering, dormancy, and branching are often selected during the domestication process and referred to as the “domestication syndrome” ( Zohary and Hopf, 2000 ). After primary tra...

Wounding of fresh produce may elicit an increase in antioxidant capacity associated with wound-induced phenolic compounds. However, there have been no reports on the wounding response of different types of fresh produce. Changes in antioxidant capacity, total soluble phenolics, ascorbic acid, total carotenoids and total anthocyanins were evaluated after wounding in zucchini, white and red cabba...
