—Cold tolerance of striped bass Morone saxatilis, white bass M. chrysops, palmetto bass (female striped bass 3 male white bass), and sunshine bass (female white bass 3 male striped bass) were compared under controlled laboratory conditions. Two groups of each taxon were acclimated at 208C in a recirculating-water system housed in an environmental chamber and were fed either a natural or prepare...

Biological packaging material based on obtained proteins from fish waste, are biopolymers that have the capability of biodegradable film formation. Thus, purpose of this research is to study and investigate some of films’ physical features made from trout fish Myofibril protein. The film forming solution containing 1.5%, 2% and 2.5%(w/v)Myofibril protein isolate of 100ml solution and glycerol a...

Bigeye snapper skin was pretreated with 0.025 N NaOH for 2 h and 0.02 M acetic acid for 2 h. Minced pretreated fish skin extracted at 80, 90, 100oC for 1, 2, 3 h and 110, 120, 130oC for 30 min were compared. The result showed that protein content and hydroxyproline (Hyp) yield of skin gelatin increased with increasing extraction temperature and time (p<0.05). The samples extracted at 120 or 130...

Sun-drying was carried out to dry fish skins of four species of seawater fish, namely yellowfin tuna, brown stingray, red snapper and white cheek shark, and the gelatins extracted from the skins were characterized in comparison to those of extracted from fresh skins. The fish skins were pretreated using 0.05 M acetic acid followed by extraction at 80oC for 2 h. The gelatin obtained was analyzed...

Edible films from chitosan, cassava starch, and gelatin plasticized with glycerol have been developed by casting method, and the effects of cassava starch (50, 100 and 150 g per 100 g of chitosan), gelatin (0, 25 and 50 g per 100 g of chitosan) and glycerol (21, 42 and 63 g per 100 g of chitosan) from the film solution on various properties of chitosan-based films have been studied using respon...

When a thin film of initially hydrated gelatin is allowed to dry from the surface, superficial changes in the structure of the material affect the local mechanical properties of the drying region. If the film is simultaneously subjected to large strain deformation (above 20%), a periodic pattern of wrinkles appears on the surface of the gelatin along the length of the sample in the direction of...

NH(4)(+) concentration in an individual droplet was determined by forming a Liesegang ring on a gelatin film containing NaB(C(6)H(5))(4). The NH(4)(+) concentration (mol L(-1) abbreviated to M) was calculated from the NH(4)(+) amount (mol) ascertained in a droplet using pixel count measurements. The droplet volume (L) was calculated by measurement of the diameter of a droplet print on the gelat...
