Escherichia coli O157:H7 is a member of the enterohemorrhagic group of pathogenic E. coli that has emerged as a foodborne pathogen of major public health concern. E. coli O157:H7 is highly tolerant of acidic pH and outbreaks attributed to this bacterium have been in many acidic foods which have pH level with similar to those of pickled products. Therefore, pickled vegetables, although acidic, m...

Mushroom is a very popular food that is consumed around the globe yet it finds very limited acceptance in India, that too mainly among the elite. Non-availability of mushrooms around the year and its highly perishable nature makes it an expensive commodity for the common people to afford. Hence pickling may be viewed as a method to increase the shelf life of oyster mushrooms from 4-7 days under...

BACKGROUND Plating and pickling processes are the most effective ways for increasing the strength of metal structures, and workers in these units are exposed to various contaminants, including acid mists. The aim of this study was to investigate the effect of protective masks in decreasing the respiratory symptoms and the aerobic capacity of workers that are exposed sulfuric acid mist. METHOD...

Pidan and salted duck eggs are of nutritional rich alternative duck egg products which are predominantly consumed in China, Thailand, South Korea and other Chinese migrated countries. Both eggs are rich in proteins, lipids, unsaturated fatty acids and minerals. A Pidan whole egg contains 13.1% of protein, 10.7% of fat, 2.25% of carbohydrate and 2.3% of ash, whereas the salted duck egg contains ...

We established a method of gas chromatography with flame ionization detector (GC-FID) using N-methyl-N-(tert-butyldimethylsilyl) trifluoroacetamide (MTBSTFA) as derivatisation reagent and DL-2,6-diaminopimelic acid (DPA) as internal standard for the determination of lysinoalanine (LAL) in Chinese preserved egg. The derivatisation reaction was under the optimized condition of 75 °C and 30min. Me...

Trivalent Chromium Process (TCP) was developed as a promising conversion process aiming at enhancement of corrosion properties and adhesion aluminium alloys. The alkaline etching acid pickling are usually applied surface pretreatments on alloys before TCP deposition in order to optimize their properties. In this work, the modifications an Al-Cu-Li alloy (AA2050-T8) different stages pretreatment...
