background: anecdotal information has suggested that sodium benzoate is used with more than permissible doses during production steps of food products especially pickles and pickled cucumbers in food producing factories in markazi province and other food producing factories . the present study was done to evaluate factual concentration of sodium benzoate in these products. methods: in this stud...

Background: Holothuroids (sea cucumbers) are members of the phylum echinodermata, which produce saponins. Saponins exhibit a wide spectrum of pharmacological and biological activities. In this study, we isolated the crude saponins from the body wall of the dominant Iranian species of sea cucumber, Holothuria leucospilota (H. leucospilota). The purpose of this study was to confirm the presence o...

The quality of Dutch cucumbers in storage was investigated by four kinds of storage technique, especially such as weight loss, soluble solid content, firmness and their appearance. The results indicates that the quality of the Dutch cucumbers stored after pre-cooling is very near that of those stored after preheating, while they are higher than that of those primarily stored. And the quality of...

The antigenic and physical properties of several representative invertebrate phosphagen kinases have been examined in order to further characterize the relationship between taxonomic assignment, quaternary protein structure and evolution of this class of enzymes. Antibodies against dimeric arginine kinase from the sea cucumber cross-reacted with dimeric arginine kinase purified from sea urchin ...

While some aspects of the phylogeny of the five living echinoderm classes are clear, the position of the ophiuroids (brittlestars) relative to asteroids (starfish), echinoids (sea urchins) and holothurians (sea cucumbers) is controversial. Ophiuroids have a pluteus-type larva in common with echinoids giving some support to an ophiuroid/echinoid/holothurian clade named Cryptosyringida. Most mole...

Experiments about the forced-air precooling of cucumbers were carried out under different operation parameters. The results show that the relation between cooling rate and air velocity can be given by power function. The linear relationship between the initial temperature of cold air and cucumbers and the final temperature of cucumbers is gained. Temperature gradient exists in different radius ...

The Galeommatoidea is a bivalve superfamily that exhibits high species diversity in shallow waters. Many members of this superfamily are associated commensally with burrowing marine invertebrates in benthic sediments. The genus Borniopsis is known only from eastern Asia and exhibits high host diversity (e.g., mantis shrimps, crabs, holothurians, sipunculans and echiurans). A new species, Bornio...
