some biochemical characteristics of common carp (cyprinus carpio) and silver carp (hypophtalmichthys moltrix) surimi prepared by a conventional washing method and protein isolated using alkaline-acid-aided processes were investigated. solubility of protein in silver carp and common carp were found to be highest by using the conventional washing method. decreases in myoglobin and lipid contents ...

Chemical changes and shelf-life of common carp (Cyprinus carpio) surimi prepared by conventional washing method and solubilization by acid and alkali processes were investigated during 5 months of storage at -18 °C. Results showed that surimi produced with acid and alkaline solubilization is significantly higher yield than the conventional surimi. Protein solubilization by using acid and alkali...

A study was performed to investigate the efficiency of rhizobacteria on solubilization of rock phosphate and their assimilation by wheat plants in quartz sand potted experiments. Two phosphate solubilizing bacteria, P. fluorescens and Serratia sp. were encapsulated in sodium alginate and potato starch beads and selected to investigate the variation on pH values, the enzymatic activity of alkali...

Isoelectric solubilization/precipitation (ISP) processing allows selective, pH-induced water solubility of proteins with concurrent separation of lipids and removal of materials not intended for human consumption such as bone, scales, skin, etc. Recovered proteins retain functional properties and nutritional value. Four roe protein isolates (RPIs) from yellowfin tuna roe were prepared under dif...

Steam explosion at 180, 190 and 200°C for 15min was applied to sugarcane straw in an industrial sugar/ethanol reactor (2.5m(3)). The pretreated straw was delignificated by sodium hydroxide and hydrolyzed with cellulases, or submitted directly to enzymatic hydrolysis after the pretreatment. The pretreatments led to remarkable hemicellulose solubilization, with the maximum (92.7%) for pretreatmen...

Waste activated sludge (WAS) originating from kraft pulp mill effluent treatment plants represents an important environmental challenge for this industry. Anaerobic digestion is a promising option WAS treatment, with the added benefit of biogas production. This paper presents application thermal, thermal-alkaline, and mechanical pretreatment methods in order to promote solubilization organic ma...

For many years the major problem impeding the elucidation of the structure of melanin and the melanosome has been the insolubility of the melanin polymer. To date, alkaline and acid hydrolysis seem to be the only methods available which can completely solubilize the melanosome (1); unfortunately, both methods degrade the constituents of the organelle other than the melanin polymer. The recent e...
