See related research by Jhanji et al., http://ccforum.com/content/14/4/R151 Adequate hemodynamic management using well-defined perioperative goal-directed therapy (GDT) is a corner-stone of tissue perfusion and oxygenation that can improve outcome.
The objective was to improve the antioxidant property of stone fish tissue by the proteolysis of its proteins and production of proteolysates and antioxidative bioactive peptides.
Many basic questions remain unanswered about the biochemical makeup of stone tissue, how it is formed and whether or not stone tissue differentiation is controlled in the same way as enb development in Arabidopsis.
In the present findings, moderate free radical scavenging and reducing power activities of crude alcoholic extracts of stone fish tissue were recorded, while those taken before adding enzyme including the bufferic tissue extracts showed no radical scavenging and very low reducing power activities.
With the aim of enhancing the antioxidant activity of stone fish tissue, the enzymatic proteolysis was carried out to digest the stone fish tissue proteins and generate proteolysates including bioactive peptides with higher antioxidative potentials.
The main component of stone fish tissue extract with the highest peak area of 59.7% identified by GC/MS was dimethyl sulfoxide, which is an amphiphilic compound with ability to dissolve lipophilic compounds [ 22].
The composition of the antioxidative compounds present in crude extract of stone fish tissue was determined by GC/MS.
In the present study, the proteolysis of stone fish tissue with 6 proteases commonly used in enzymatic proteolysis of animal products, including alcalase, bromelain, flavourzyme, papain, pepsin, and trypsin was carried out under their optimum conditions for 24 h.
It is obvious that proteolysis of stone fish tissue by proteolytic enzymes can considerably enhance its antioxidant activity.
The enzyme was re-added every 5 h, in order to complete the digestion of stone fish tissue proteins.
