Superheated steam drying technique has been known for a long time, but its application to food drying has received little attention. In this work, superheated steam was applied to dry fresh parsley (Petroselinum Cripsum). A mathematical model to simulate this drying process was developed by using mass and energy conservation equations for solid and steam phases. The resulting partial differenti...

The activity of caffeoyl-coenzyme A (CoA) 3-O-methyltransferase, an enzyme widely distributed in plants and involved in cell wall reinforcement in a disease resistance response, appears to be subject to a complex type of regulation in vivo. In cultured parsley (Petroselinum crispum) cells treated with an elicitor from Phytophthora megasperma f.sp. glycinea, the enzyme activity is rapidly induce...

A simple test for shelf-life assessment of frozen spinach and parsley is presented. specific that considers three storage temperatures proposed to accelerate the rate quality decay in parsley. The scope was provide a reliable rapid way (one month vs years) predict by using experimental approach mathematical models based on some physical product attributes. Physical properties were evaluated at ...

yersiniosis is a common infection in human and animals. yersinia enterocolitica infection has been associated with a variety of clinical manifestations. this bacterium has been isolated from water, meat, milk environment, animals and so on. our studies have been accomplished about isolation of y. enterocolitica from vegetables such as lettuce, carrot, celery, parsley, tomato, cabbage, radish, m...

The common plant regulatory factors (CPRFs) from parsley are transcription factors with a basic leucine zipper motif that bind to cis-regulatory elements frequently found in promoters of light-regulated genes. Recent studies have revealed that certain CPRF proteins are regulated in response to light by changes in their expression level and in their intracellular localization. Here, we describe ...

Suspension-cultured cells of parsley (Petroselinum crispum L.) were used to study the regulation of extracellular H2O2. After resuspension, the washed cells regulated the H2O2 concentration spontaneously to a constant level that was greatly increased when the cultures were pretreated for 1 d with salicylic acid (SA). The H2O2 level was further increased on addition of a fungal elicitor preparat...

AIM To investigate the bactericidal and anti-adhesive properties of 25 plants against Helicobacter pylori (H. pylori). METHODS Twenty-five plants were boiled in water to produce aqueous extracts that simulate the effect of cooking. The bactericidal activity of the extracts was assessed by a standard kill-curve with seven strains of H. pylori. The anti-adhesive property was assessed by the inh...

Fungal elicitor stimulates a multicomponent defense response in cultured parsley cells (Petroselinum crispum). Early elements of this receptor-mediated response are ion fluxes across the plasma membrane and the production of reactive oxygen species (ROS), sequentially followed by defense gene activation and phytoalexin accumulation. Omission of Ca2+ from the culture medium or inhibition of elic...

We have combined in vivo genomic footprinting and light-induced transient expression of chalcone synthase promoter derivatives in parsley protoplasts to identify cis sequences regulating light activation. The parsley chalcone synthase promoter contains two cis "units" that are light-responsive. Each unit is composed of short DNA stretches of approximately 50 base pairs, and each contains two in...

This study evaluated the degree of parasitic contamination of vegetables which are commercialized and consumed fresh in Benha, Egypt. It included 530 vegetables: lettuce, watercress, parsley, green onion, and leek. Vegetables were collected randomly from markets within Benha. Samples were washed in saline, and the resulting washing solution was filtered and centrifuged to concentrate the parasi...
