An investigation of green tea’s effect on mackerel (Scomber Scombrus)’s protein structure during frozen storage by FT-Raman spectroscopy

نویسندگان

چکیده

FT-Raman spectroscopy (FT-RS) was used to investigate green tea’s potential protective effect as an antioxidant during frozen storage of Atlantic mackerel (Scomber scombrus). stored for more than 26 weeks at −10°C or –80°C (control), with without tea (GT). Raman analysis showed substantial changes in protein structure due storage, especially the higher temperature (−10°C), compared findings −80°C instant GT, indicated by a decrease tyrosine doublet ratio, a-helix content. O-H stretching band intensity, along increase tryptophan intensity and β-sheet structure. GT concentration ~250 ppm can protect fish proteins limited period. However, optimal freshness, should be very low temperatures.

Population Structure of Atlantic Mackerel (Scomber scombrus)

Atlantic mackerel (Scomber scombrus) occurs on both sides of the north Atlantic and has traditionally been grouped into 5 spawning components, some of which were thought to be isolated natal homing stocks. Previous studies have provided no evidence for cross Atlantic migration and no or weak support for isolated spawning components within either side of the North Atlantic. We question the de-fa...

Aldehyde formation in frozen mackerel (Scomber scombrus) in the presence and absence of instant green tea.

The effect of frozen storage on lipid peroxidation in Atlantic mackerel (Scomber scombrus) stored for up to 26 weeks at -10 or -80°C (control), with and without green tea antioxidants, was investigated. Hydroperoxides (PV) and aldehydes (TBARS) were measured by HPLC and LC-MS and hexanal by GC. There was an increase in peroxide value which was associated with an increase in aldehydes, followed ...
